The invention relates to methods for data transmission, in particular transmission of multimedia data to subscriber systems with bilateral mode of operation, for example, when a subscriber sends a signal program selection, and can be used in multiservice networks transmit digital data, including voice, video, audio and data Internet Protocol.

Under multimedia data can understand the simultaneous use of different forms of information representation and processing in a unified object-container. For example, in the same object container (eng. container) can contain text, audio, graphic and video data, and possibly interactive method of interaction with such information ().

A distinction is made between linear and non-linear method of transmitting data, including multimedia data. In the case of the linear method of transmitting user data in any way cannot affect the acquisition of these data and gets them in direct mode. In the case of nonlinear data transmission method, the user is able to interact with the display tool multimedia data by using certain software and/or hardware to ensure the participation of the user in the selection and transmission of multimedia data. This involvement of the user in the process� data transmission is also known as "interactivity".

The applicant there are many ways of allocating channel resources in a broadband access system during data transfer, including multimedia data, among which the most similar in essential features are as follows.

Known method of transmitting video data that contain video services, described in patent RU 2384969 published 20.03.2010 in Bulletin No. 8, IPC: H04N 7/16, H04L 12/28. In accordance with this method, realize transmission of video data in a broadband access system, a transmission from a user terminal to at least one server services through the channel of the broadband data that includes a request to receive video data, the identification of the user terminal in a broadband access system, a transmission from at least one server of the services to the user terminal, the video data in accordance with the request received from the user terminal. The transfer of video data from at least one server of services carried out through a gateway service using the broadband access device, on the built-in component video services which carry out the storage of video data that are transmitted. Transmits video data to the user terminal in accordance with his request is carried out from the built-in component video device broadband. Videodan�s contain video unicast and multicast.

The presence of additional built-in feature, video services in the broadband access device allows to optimize the allocation of channel resources in a broadband access system during transmission of video data in case of interference in media content and the loss of some packets are unicast or multicast, i.e. when functioning in the mode of an emergency situation. This is accomplished by localizing packet loss and re-sending of lost packets on the user's device in the mode of individual unicast. This approach gives the possibility of reducing the requirements of video services using the frequency band broadband systems and reducing limitations in bandwidth in systems with limited resources environment data.

However, the specified technical result is achieved by the presence of an additional component, which complicates the resource management system of broadband access. Also transfer video with Videology to some extent limits the scope of application of this method. Moreover, this method does not provide cost savings and efficient allocation of channel resource in the normal mode of operation of the transmission media in General during the transmission of video data from the service to the user terminals through op�imitatie of video streams directly or content of threads and not corrective messages.

Also known way to perform operations on transfer of multimedia data in accordance with the patent RU 2391780 published 10.06.2010 in Bulletin No. 16, IPC: NN 60/91, H04N 7/173. According to this method, realize transmission of video data in a broadband access system, a transmission from a user terminal to at least one server services through the channel of the broadband data that includes a request to receive video data, the identification of the user terminal in a broadband access system, a transmission from at least one server of the services to the user terminal, the video data in accordance with the request received from the user terminal. Also further comprising recording the user-selected media data (content), i.e. data that is transmitted via a channel of a broadband access system, and storing them in a database in accordance with a user request sent from his terminal during the transmission of these data from the server services through the channel of the broadband data to the user terminal. Also ensure the cessation and resumption of the above save when the user changes the channel of a broadband access system or a return to the receive data of this channel. Preservation, termination and resumption �recording, i.e. operations with data being transferred, is carried out using a controller, which is controlled by software of the user terminal.

In accordance with this method, achieve a reduction of the period of delay associated with the switching of channels, the presence of the controller, which is controlled by software of the user terminal. This method allows the user to move quickly through the channels, and special software buffers not only adjacent channels, but the channels based on user preferences according to statistics hits. This method allows for independent selection of a certain channel by the user and obtaining data of this channel, to optimize the reception to the user terminal programs from the media data, but does not allow to optimize the use of bandwidth broadband access systems in General. The method allows for the saving of resources for a specific terminal user that does not improve the efficiency of the allocation of channel resources in a broadband access system with the tastes of all users of a medium, localized to certain areas.

Also known system and method for establishing a filtered list of TV programs n� the basis of the user profile in accordance with the application of US 2003/0063117, published 03.04.2003. The method includes transmitting data, TV channels with content by broadcast to at least one of the access devices of the user.

According to the application US 2003/0063117, filtering a subset of the channels received in broadcast mode (broadcast). The results are displayed in the electronic program schedule (EPG) in a system which contains at least one television (TV) that displays EPG multiple channels, at least one media hub connected to the TV, several removable media, which can be connected to the hub for transfer of user profiles.

To implement this method is carried out the connection or integration of the media hub to the TV, the hub stores the user profiles. The contents of the electronic schedules of TV programs and the list of channels is filtered based on the profile, which is contained on removable media. Selection of programs is based on the formation of group preferences based on the analysis of the profiles loaded into a media hub so that such preferences provided interest group.

The disadvantage of this method is that the system provides coordination group selection based on user profiles, but only filters the data with EPG and Kahn�s broadcast on the local device, and in no way associated with the media content, and does not evaluate its resources. Thus, the invention under the application US 2003/0063117 can not ensure the communication channels that are aligned in a user group, in the data environment with resource constraints.

Also known a method of providing program access services from the list of Multiple Triple Play at the request of US 2007/0261085 published 08.11.2007 G. the Term "Multiple Triple Row" involves a set of telematic services, i.e. information and telecommunication services. Respectively [K. Seliverstov, the Implementation of Triple Play services in FTTx access networks, "journal of communication, No. 4, 2010], consumers telematic services can be offered the following services - data transmission HSI (High Speed Internet), video BTV (Broadcast TV), VoD (Video on Demand, Video on demand), nVoD (near Video on Demand, also used as PPV - Pay per View, imitation, home theater, voice VoIP (IP telephony). Especially critical to the allocation of channel resources in a broadband access system is the transmission of video data BTV (Broadcast TV), or IP-TV. Respectively [http://ru.wikipedia.org/wiki/IPTV], IP-TV is a digital interactive television data networks over IP. The main advantage of IPTV is an interactive video service and a wide range of additional services. Feasible�STI IP Protocol allow to provide not only a video service, but a much broader package of services, including interactive and integrated. Thus, the main advantage of IPTV is its interactivity.

According to the application US 2007/0261085, in the method of providing program access to the list of services Multiple Triple Play realize transmission from the user terminal to at least one server services through the channel of the broadband data that includes a request to receive data, including multimedia data, the identification of the user terminal in a broadband access system, a transmission from the at least one service to the user terminal data, including multimedia data, in accordance with the request received from the user terminal, the formation of a single schedule data, including multimedia data, for at least one of the user terminals or at least one group of devices, user access, data transmission over IP networks, including multimedia data, for at least one of the user terminals or at least one group of users in accordance with the schedule. In this case, the user is offered a list of data, including multimedia data, from which it by means of a terminal access system broadband access necessary data selects Dunn�e, that are sent or will be sent by broadcast (BTV), in certain time intervals. Also form additional list of data, including multimedia data, which the user can browse in private mode (VoD/nVoD/PPV) for at least one of the user terminals or at least one group of user terminals, send it to the user and the user can perform the query using its terminal to receive certain data, including multimedia data, integrating the individual services with a pre-formed schedules into a single schedule.

The disadvantage of this method is that the system is in no way associated with the media content does not assess its resources and cannot provide the transmission channels that are selected by each user, in the presence of medium to resource constraints. Also, the system does not coordinate group selection, and focuses only on the content that is broadcast, multicast, or are in the database for individual viewing. The schedule of thematic content is also formed on the pre-created PPV or nVoD channels, the number of which is not regulated depending on the state and resource constraints of the media content. In addition, the choice to�of ntent users is carried out from a pre-formed Studio of the list of content units, rather than from the free choice of user content units by vote. Also missing is the mechanism to secure the necessary bandwidth in a parity situation that users can select some of the content units in General, and subject to the limitations of resources of the transmission medium of the content.

Known method of transmitting data in a broadband access system, including multimedia data (application US 201002836 published 21.10.2010). According to this method, realize transmission of multimedia data to the access device of the user in the form of a stream of content-units, in particular, the digital audio data stream (Internet radio) by broadcasting in the broadband access system. Also form the local base of multimedia data, including audio data, which contain the identifier (metadata). Establish a database with a user profile that contains information about user preferences regarding multimedia data. On the basis of the generated database of user preferences determine the relevance of the following content units from the stream of multimedia data to the user's preferences. In the absence of relevance, realize transmission of multimedia data from the local database that are relevant to the user requests�La. And continuously (seamless) switching source data by joining with the previous content of the unit.

The described method allows continuous transmission of multimedia data to the device user that match his preferences. This method does not take into account the preferences of the user group in relation to multimedia data, which is especially important in the broadband access system. Moreover, the method does not allow to consider the state of the environment data with a limited resource. The disadvantage of this method is the fixed program data, that is, the difficulty of choosing the content of a unit of a user or group in forming the list of transferred data (feedback), making it impossible to dynamically change the list of data to include the content of units available for transmission to the access device, but not included in the list of data during its formation. This leads to the impossibility of formation of dynamic broadcast and multicast of multimedia data to meet the preferences of groups of users depending on the user's location with regard to the workload of the data transmission channel, especially when implementing a wireless LAN system�th broadband and, as a consequence, the lack of saving resources channel system wireless broadband access.

Also known a method of transmitting data in a broadband access system, including multimedia data (application US 20100267331 published 21.10.2010). According to this method, determine the relevance of multimedia data to the user's preferences for information about multimedia data contained in the library of multimedia data on the user's device or remote databases (libraries, broadcast studios, and then to recommend to the user a connection to the stream of multimedia data, in particular Internet radio that fit their preference. Thus also perform the analysis and clustering of content units using data on user preferences.

This method also allows continuous transmission of multimedia data to the device user that match his preferences, without data on the preferences of the users from themselves, which simplifies the formation of a database of user preferences and to consider the preferences of groups of users by exchanging data with remote databases.

The disadvantage, as in the previous method, is the lack of analysis of the load at redeparede data and conserve its resources, as it does not use information about the content units that are transmitted in the data transmission system at the moment, and about the resources channels. Therefore, the method does not allow for the calculation of loading and release of transmission media for broadcast and multicast messaging, create a list of data to transfer (a program) in accordance with the preferences of the user group, the distribution of the frequency resource in a given time taking into account the preferences of users, grouped on the basis of location.

As a prototype adopted a method that can be implemented through a system of automatic generation of an electronic schedule of programs, according to the patent EP 1387583 B1, published 02.11.2005 G. in the Bulletin 2005/44, IPC: H04N 7/173, H04N 5/445. According to this method, as according to previous, realize transmission from the user terminal to at least one server services through the channel of the broadband data that includes a request to receive data, including multimedia data, the identification of the user terminal in a broadband access system, a transmission from at least one server of the services to the user terminal data, including multimedia data, in accordance with the request received from the user terminal, the scheduling of data transmission, including h�the following multimedia data, for at least one of the user terminals, the transmission, including multimedia data, for at least one of the user terminals in accordance with the schedule. In this case, the scheduling data, including multimedia data, for at least one of the user terminals, is carried out not only through the receipt of requests from users and their subsequent processing, but also searches for other multimedia data, for example, television programmes, which are relevant to the user request, for inclusion in the schedule that is sent to the user. Thus provide a database with information about the types of data, particularly multimedia, which is prevalent in requests for a specific user, and use this database when you perform a search.

This optimization while scheduling the transmission of data, including multimedia data, for at least one of the user terminals, allows to take into account the statistics of users to save time search for a channel, create a personal channel for a user, and perform the inclusion in the schedule and the user's other data, in particular advertising, which are characterized by the information about the preferences of the user, taken from pre�tion generated databases.

The disadvantage of the prototype is the lack of ability to control resource environment of a broadband access system during data transfer in systems that have physical, resource and other constraints, for example in systems of high-speed wireless transmission of data from the application servers, i.e., sources of data, including multimedia, to the user terminal. The system does not take into account the possibility of grouping users by any criteria and change user group sequence of data transmission, including multimedia, or other users of the data, which differ from pre-formed in the Studio schedule for channels multicasting or broadcasting. For such systems it is expedient to carry out not only the formation of a database with statistics about user preferences, but also take into account the localization of users who, together with the known state of the media content with limited resources, will be allowed to perform the best, from the point of view of saving resources of media content, optimizing schedules based on group preferences. The absence of a description of the distribution of users by type of data that they request and which are transmitted at the moment, is also weeks�the shortcoming of this method. Also for the specified method is carried out so-called "seamless" creating a schedule for data transmission, which serves to fill the gaps between the transmission of the data to use only data nVoD), which to some extent limits the use of the method. Also the implementation of such a "seamless" formation of the schedule of data transmission involves a fairly intensive user interaction, which reduces the attractiveness of this technique, and for the user too. In addition, the selection of content by the users is carried out from a pre-formed Studio of the list of content units, rather than from the free choice of user content units by vote. Also there is no mechanism for resolving the situation of parity that users can select some content units overall, including in situations with limited resources of media content.

The basis of the invention is improving the efficiency of distribution frequency of channel resources in a broadband access system during data transfer, including multimedia data, especially for broadband wireless access systems with limited data rate in the channel, while maintaining the mass quantity of users that receive these �data and additional ease-of-use and reduces the time required for generating the user schedule data, including multimedia data, i.e. increasing the "interactive" component of the multimedia data transfer.

The problem is solved by a method of allocating channel resources in a broadband access system during data transfer, including multimedia data, which includes transmitting from at least one device user's access to the core network broadband access systems through the channel of the broadband data that includes a request to receive data content, including multimedia data. Access device user broadband identify through access broadband access systems. Data content, including multimedia data, from the core network broadband access systems to the at least one access device of the user is passed in accordance with the request received from the access device user. Schedule transmission of data content, including multimedia, form for at least one of the access devices of the user or to the at least one group of access devices users. The data content of the transmit unicast/�, multicast or broadcast distribution, including multimedia data, for at least one of the access devices of the user or to the at least one group of devices of the user access in accordance with the schedule.

According to the invention, carry out the formation of the base gear of constant content-channels, which contains a set frequency parameters and/or modulation method of the input signal is broadband access for multimedia communication of constant content-channels and/or identifiers of constant content-channels, the list of content units, the metadata of the content units. Also carry out the formation of the base current dynamic content-channels, which contains a list of content-units of current dynamic content-channels, metadata, content units and identifiers of current dynamic content-channels. Also carry out the formation of a database of multimedia data services, VoD and/or nVoD (PPV), which may contain the same content units of permanent or dynamic content-channels. Base multimedia data services, VoD and/or nVoD can be combined with the base gear of constant content-channels and base current dynamic content-channels. Also carry out the formation multimedia data channels that contain content of a unit of advertising and/or information�wow content. Send at least one device access the user data packet containing a content of units of constant content-channels, current dynamic content-channels, metadata, content units, and/or data services VoD and/or nVoD, and/or multimedia data channel. On the access device user guide data contains a request for selection in the time interval T content-units of permanent content-channel or dynamic content-channels or VoD and/or nVoD. Carry out the formation and transmission from at least one device user's access to the core network and broadband access data on the user selecting at least one content unit of current dynamic content-channel or content units of constant content-channels or VoD and/or nVoD. Establish a database on the server of the network core, which contains data for each of the identified users or for each group of identified users, which contains information about the users of the content units content-channels or VoD and/or nVoD. Determine the number of users with the same selection of content units in a time interval T on the basis of the created database, and based on this statistics realign the existing or form new groups�of isolately. Establish at least one threshold value for the number of users with the same selection of content units. Form schedule data with content items of current dynamic content-channel and/or content units of permanent content-channel and/or the services of VoD and/or nVoD in accordance with data received from at least one access device of the user for at least one access device of the user or to the at least one group of access devices users. Increase the number of transmissions of data packets multicast and/or broadcast downflow channel broadband for content-unit, which is selected by the number of users is greater than the threshold value, and/or multimedia data over the time interval t1<T<t2where t1- start of broadcast of the content unit that elected the number of users is larger than the threshold value, and t2- completion of translation of the content unit that elected the number of users is greater than the threshold value, respectively, to the schedule. Then reduce the number of transmissions of data packets multicast and/or broadcast downflow channel broadband access to content units that elected �the number of users greater than the threshold value, at time tK>t2. Carry out the formation and transmission to the at least one device user access a data block that contains data with an information message to users about access time t3to content the unit chosen number of users, smaller than the threshold value, or informational messages about the possibility of downloading a content unit that the selected number of users, smaller than the threshold value, via VoD and/or nVoD, after time t4>t3. Transfer the content units of permanent content-channel in accordance with the current data transmission permanent content-channel on the access device user or content units of permanent content-channel, content, or any other attributes or metadata close content-unit, which was broadcast during T, or content-unit permanent content-channel, which is elected by the majority of users in accordance with the statistics database to the at least one access device of the user, from which no information was available on the user selecting content of a unit of the respective request. Carry out the formation and distribution of data that includes contextual advertising, or background information on devices�about the user's access of a group of identified users, formed according to the statistics of the database. Carry out the formation and distribution on the access device user posts about switching to another current dynamic content-channel or for download and playback of pre-formed data via VoD and/or nVoD identified on the access device of the user for each of the groups identified users, formed according to the statistics of the database. Carry out the formation of the database on the server of the network core, which contains data for each of the identified users or for each group of identified users, formed according to the following criteria: data about the query or the selection of content-units or content-channels or VoD services and/or nVoD, or data with feedback about the content-tinize or content channel or service VoD and/or nVoD, or data on the number and time of transitions between content-channels or VoD services and/or nVoD, or send multimedia data through the channel system is unicast or multicast.

The above set of essential features leads to a saving of channel resource broadband access depending on the data type of the content units and the processing statistics of requests for content units that come �t access devices of users and/or groups of users.

Also, as creating a schedule for transferring data using search queries from access device of the user, and searches the content units according to certain similarity criteria, save the resource of the transmission medium content by connecting the device user's access to the content unit, the data content of the channel which has already passed. Preliminary data is sent with information about connectivity to the content channel with a content unit that responds to a user request, the access device user. In this pre-assess the resources of the media content to obtain information about the time required to obtain data that contain the necessary content unit and order form send data to the at least one access device of the user, for example, for a day or for a few days. In such cases, the grouping of multiple access devices users into groups according to certain criteria, for example, depending on the type of content units that are requested. Also, after the formation of the order data, the possible implementation of a more accurate calculation of channel resources required broadband access to perform data transfer with the aim of improving the economy of these resource�in:

- set the order of data transfer to reserve speed for each content unit in accordance with the request from each access device of the user or any group the user devices

- simultaneous data transmission for the access devices of the user from whom the request was made to receive the same or similar content units;

- switch access device user to receive data with a content channel, which correspond to the request from the access device of the user and which is already transmitted in the medium.

Also the above features allow the formation of a certain dynamic content-channel, which will be broadcast to a group of users, selected according to certain criteria, for example, for users of some social networking site, residents, visitors of any institution, etc., i.e., this channel contains content units that meet the needs of the user group or similar in content or other characteristics or metadata with them and broadcast time which is agreed in accordance with their wishes. Thus, unlike their counterparts listed in the section "prior art", the formation of such a channel can be provided not only in advance but also during the data transmission, and they�NGO formation data with content units can be implemented with the participation of the user by sending him a request and receive data from it with his choice, and in "background" mode, i.e. without user action.

The expediency of such a dynamic channels, the content of which will be carried out accordingly to user requests collected in a group according to certain criteria, in networks with limited resources of a data channel, dictated by trends in the development and growth of video data, the personal video content units, Web-TV, as well as interactive and/or personalized advertising (source: Cisco VNI forecast), as well as interactive content units (presentation Apple Event January 2010), while growth and promotion of social and group services. Experience from the history of the transmission of video data for target groups is widely used in such services as Apple Event Live, Cisco WeBex seminars, a grouping of videos on YouTube. Similar results are confirmed by the statistics view user content units television (branch butt "Television in Russia 2010", Federal Agency for press and mass communications, may 2010), moreover, the audience is subjected to segmentation.

Example of possible use of the saving method of channel resource broadband access may be building a data network that uses LTE technology (full name 3GPP Long Term Evolution), mobile technology�Noah data WiMAX (eng. Worldwide Interoperability for Microwave Access), telecommunications technology was developed to represent universal wireless connectivity at greater distances for a wide range of devices (from desktops and laptops to mobile phones) or network of BARS (patent of Ukraine No. 26552), which are formed using radio links point to point or point to multi-point, or other wireless and wired data transmission, where there is a lack of frequency resource channel broadband access in case of simultaneous transmission of the content units. The introduction of such dynamic content-channels as a way of saving the resource channel, can create a natural transition from the model of content-channels, data is constantly being transferred to a fully personalized content channels.

For example, LTE is obvious that in the radio frequency channel, which consists of several sub-channels with a total speed of up to 300 Mbps in a descending channel (DL channel, Download channel), will be available in 3 groups of data: the multicast data of constant content-channels (1/N bandwidth broadcast, multicast data transmission of current dynamic content-channels (1/M the capacity of the cell broadcast channel access and transmission of multimedia data services VoD/nVoD and other data are sent to the device d�stupa user (1/To the capacitance of the cell broadcast channel access), which together make up the Bandwidth), i.e. nominal bandwidth bandwidth (K+M+N=1) in the medium of information transfer. It is possible to transfer data of permanent and current dynamic content-channels single channel system formed by the transport of the DVB-H (eng. Digital Video Broadcasting - Handheld) and/or similar data transmission technology digital video signal to mobile and stationary devices user access. Meaning all of the content transmission channels content units and other data from the point of view of the access device of the user form a single transmission medium, the content of items in a broadband access system.

As described above, the LTE scheme works similarly in the specified system BARS or other similar system. When using additional capacity, for example, existing networks in DVB-T or DVB-H, the possible joint use of their resources.

In a microwave radio link is possible, such a scheme of organizing data.

The use of these three content types allows you to enter additional parameters in the model, QoS (Quality of English Serv ice, quality of service). This term in the field of data transmission is called the probability that the system is broadband (media information) meets the specified regulations on the transfer of data. Introduction �additional parameters permit greater flexibility to manage resources, broadband access systems, depending on various conditions, that affect the data transmission channel. In particular, changing weather conditions resulted in a decrease in data transfer speed in the channel. Therefore, the operator who organizes the broadband access system using the described method save channel resources, can pre-allocate resources for all three data types. When reducing the data rate in the channel is guaranteed to retain data with constant content-channels, reduce data transfer with dynamic content-channels and also will decrease the rate of transmission of other data in the channel. Since the number of dynamic content-channels can be adjusted respectively by the proposed method at a time, reducing the data rate can be flexibly limit the conditions for the creation of new dynamic content-channels and ensure that these savings resource channel broadband access systems.

Additionally, a list of content units that fill dynamic content-channel, may display additional information, including from other users about the content unit by extracting the metadata and sending them from the respective bases of the transmission of content channels on the access device user. For example, such information may be the number of "�of podpischikov" content-units, i.e. the number of requests for the same or similar content unit received from the access devices of users, or user rating of the content unit, or other metadata.

Thus, the claimed method allows you to save channel resources broadband access simultaneously with the transmission via a multicast or a broadcast e-mail to only those data that are necessary pre-defined or the vast majority of users in accordance with their request in a certain time interval, allowing the access of other users to the data that they require a convenient way for them.

Also, the claimed method allows to increase the usability of the list of content units, in particular to reduce the time spent on the formation of such a list, as well as to improve convenience of a user of the content units in accordance with their requests.

Additional data for transmission by the broadband access system may include data IP packets, and/or storage of the signal and/or video and/or multimedia data channel.

Thus, data transmission is achieved, which at least include the Triple Play services, i.e. high-speed transmission of Internet data, Internet television data and Internet telephony.

Also can increase the width of the frequency range downstream channel broadband access to content units that elected the number of users is greater than the limit value, and/or multimedia data over the time interval.

Also can realize the reduction of the width of the frequency range downstream channel broadband access to content units that elected the number of users is greater than the limit value, and/or multimedia data, at time t2.

Thus, reach flexible regulation of channel resources depending on his workload a certain time interval.

Additionally, when forming the data, which contain a schedule of content-units of dynamic content-channels, constant content-channels, services, VoD and/or nVoD, can add data with audio, video fragments of content units.

Thus, in addition send information data to improve user experience by compiling a list of content channels, as well as for the possibility of obtaining user data to advertising or informational nature.

Can also provide the user access to the database that contains the data� for each of the identified users or for each group of identified users.

Thus, in addition to inform users about the ratings of individual content items or content channels, thus reducing the operating time of the user over the list of content channels.

Can also provide transfer of data blocks between the device user and the server services the core of the network by creating two-way communication between base station and subscriber station system wireless broadband access.

Thus, provide a system of conditional access data through a system of high-speed wireless broadband access, making it possible to send digital services and media content units, for the access device of the user.

Can also break each block of data into N-parts in the Converter of the direct channel of the base station.

Also can encode each of the N-pieces of data block own coder base station in a transport code.

Also can convert each encoded N-a portion of the data block in the corresponding N-modulator direct channel of the base station to the signal.

Can also transmit a signal to the receiver in the subscriber station using the base station's antenna.

Can also perform demodulation of the signal in N-demodulators �abonentskoy station.

Can also combine N pieces of demodulated signals in the data block in the Converter in the subscriber station.

Also can form a database, which contains information about the user's choice, for each sector antenna of the base station.

Also can convert each encoded N-part of the block of data in the signal using the corresponding N-modulator direct channel of the base station, separately from the corresponding N-transmitter base station.

This division of the data block into pieces and ensure their transmission and reception between a subscriber station and a base station of a wireless system allows the flexibility to scale up or broadband access and optimize bandwidth broadband access depending on the type of data, i.e. data for broadcast, multicast or unicast.

Can also provide transfer of data blocks between the device user and the server services the core of the network by creating two-way communication between base station and subscriber station system wireless broadband access using a duplex channel with time division or duplex channel frequency division.

When it� this method allows data transfer from base station to subscriber stations without encapsulating them in a DVB transport stream, so the speed of the downward flow of a single trunk may reach considerable values of tens or even hundreds of megabits per second).

Can also provide transfer of data blocks between the device user and the server services the core of the network by creating an ascending (UL) of the communication channel between a subscriber station and a base station system wireless broadband access using channel time division or channel frequency division.

Can also provide transfer of data blocks between the device user and the server services the core of the network by creating two-way communication between base station and subscriber station system wireless broadband access using an asymmetric channel.

Thus, increase the speed of the broadband channel access by dividing the input and initial data regarding the access devices of the user based on the statistics regarding the correlation of data streams from/to the user and the state of the environment data.

Drawings that illustrate the invention and shows an example of embodiment of the method of allocation of channel resources in a broadband access system during data transfer, including multimedia data, in any rank do not limit the scope of the claims set forth in the formula, but only to explain the essence of the invention.

A data transmission environment, which is part of the data transmission system, consists of three levels: core, distribution level and the access level (Fig.1). Under the media content is commonly understand a set of bands, frequencies, ka�Alov communication equipment that comprise a unified media content between servers, networks, devices, user access, communication centers, etc.

The core network may be connected to at least one source of content units, which can be a television Studio, network, Internet or other, and can be United with the databases that contain the content unit metadata or statistics. Metadata is information that describes the content of the unit. An example of such information may be data packets EPG (English - Electronic Programs Guide), i.e. the service "TV guide", an interactive service media content channels, which is implemented through a system of broadband access, in particular during the transmission of the content channels using MPEG-streams (MPEG, group for the manufacture of standards for digital video and audio, MPEG-streams also contain a stream of MPEG video data and MPEG audio data). Also an example of such information may be Program Table (MPEG-streams). As sources of metadata can be used external sources of metadata that describe the content of the unit, as for example, in the XML-TV (the XML file format for describing TV programs IP-TV) or WEB-TV (the software for the transmission of television content channels), as well as the content units that are created by users,�geoconference, video calls, etc., as well as statistics on them.

The access level of the environment is also combined with access devices users.

Typically, the source content units or transmits data with content-channels, which are real-time services, or data flows on request from the access device user. Example of data with content units may be separate television programs, radio programs, movies, etc. Data with content units can be written into the multimedia data services, VoD and/or nVoD or are sent multicast.

Each content channel is identified by its ID. Identifiers of content channels is data that is intended for marking each content channel, or its smallest components, including transportation, which are then used in the process control data transfer with content channels. Example identifiers may be PID, IP, group ID multicast, MPLS network, VPN ID, etc.

For some systems, broadband access is known in advance a limit on the amount of data with content channels that can simultaneously be transmitted by the channel of broadband access. Therefore, as a rule, the data with a certain number of content channels transmit media content const�about, but data from another part of the content of the transmit channels in the media content accordingly to the requests coming from the devices user access. This pattern of data with content-channels in conformity with the policy broadcasting networks in the broadcast television (TV broadcast) today. Under this policy, the portion of data that includes television channels, for example, nationally in Ukraine or in Russia Federal, will be transmitted continuously in the system, i.e., for transmitting the data allocated system resources, in particular, sets or IDs, or frequency parameters and modulation method of the input signal is broadband, for transmitting multimedia data of constant content-channels. Other data that contain content channels that will be transmitted to the user in case of receiving the signal they receive from the access device user.

Accordingly to the invention, content channels broadcasting on the user's device continuously, called constant content-channels and other available content feeds is called dynamic content-channels.

Metadata, descriptions, identifiers corresponding to the content of the channels entered in the database transmission of constant content-channels in the base of current dynamic content-channels. Under the base gear permanent con�UNT-channels and base current dynamic content-channels referring to the database, in which retain information about those content units relevant content channels, which broadcast their description, identifiers of content channels. Also, each base is connected with storage devices, such as servers, through which some form of buffer to record the content of units and transfer them to devices access user specific offset in time, for example, if it is a different time zone.

In addition, the database of current dynamic content-channels records information about the identifiers of those of the dynamic channels whose data is passed at this point in the media content at the user's request.

Managing data with content-channels is performed by assigning a content channel identifiers for delivery of content units to the devices user access.

Reception, processing and further distribution of the data before input to the transmission medium of the content (as a rule, these functions are performed by the main station, Head-end, link: http://en.wikipedia.org/wiki/Head_end) is as follows.

Respectively of Fig.2, transmit data with content channels from the teleport or source content units to the base transmission for all channels teleport to the base content for VoD and/or nVoD for recording the content units. Typical teleport represent�t a set of means of satellite communication (usually designed for simultaneous operation through several transponders), means of connection with terrestrial networks of General use, and support systems (systems of guaranteed power supply, security, etc.), source http://www.connect.ru/article.asp?id=7954.

Carry out the simultaneous transfer of data with a fixed number of constant content-channels to the transmission of constant content-channels and data transfer with other content channels that are broadcast at the moment the demands received from the device user's access, including via VoD and/or nVoD, to the basis of current dynamic content-channels. As a result, the current content constant content-channels and stream content dynamic content-channels is sent from the respective databases via the media content to the device groups user access.

Respectively of Fig.3 and Fig.4, the data transmission of constant content-channels and current dynamic content-channels according to requests from access devices of the user is as follows.

Users get data with content channels on the access device of the user (PC, STB (Set Top Box, player, TV, smartphone, etc.) and view them, for example, through a control interface. One option p�inspection of the content of the channels is the choice of the content channel switching according to its number or select from the list of content channels similar to the conventional television channels. The user can cause the information retrieval menu with a list of gear, with specification of genres or other additional information concerning the content of the channels or content units to facilitate user navigation. In addition, the user can enter their search keys via the control device interface user access to search the most suitable content of units that should be sent in the moment through content channels. After sending team of choice or switching with the remote control device a user's access is the order of the content channel to receive it from the media content.

May occur a case where the user is unsatisfied content units that pass through the permanent and current dynamic content-channels, or wishes to receive the content unit, including exclusive, with multimedia data using the services of VoD and/or nVoD (Fig.5). In this case, search a database of content for VoD and/or nVoD and, if the search results satisfy the user, display the access device of the user. The search results may contain the attached metadata such as rating, novelty, duration of the broadcast content units, etc., Thu� improves the selection by the user.

If, according to the search results, are the same or similar content units already passed in the environment of the broadcast content at the time of the search, the user can send a message with a connection request, to view these and already broadcasted content units on the broadband access device. This enables the saving of a resource of the media content if the user doesn't care, since what moment to review the content of the unit. Thus, the probability of connection of users to view the content of a unit with a high rating is high enough, if he checks the content of the channels that he was not satisfied.

Data transmission services VoD or nVoD is carried out immediately after confirmation by the user receiving the selected content units (VoD), or after matching received content units (nVoD) using menu this service. To perform this estimation of resources of the media content and send messages to the user about the time required to send data to VoD or nVoD.

While there are a variety of patterns of transmission of the content of units of services VoD or nVoD, for example, by means of forming the list of content units that respond to a user request, for a day or a week, and the timing of sending these content units. In this �inappropriate, after receiving these lists, the content of units from multiple access devices of the user/s, carry out a correction calculation resources in a broadband access system, thereby conserving resources of the media content.

Respectively of Fig.6, when implementing the procedure to search for content units in accordance with a user request in a broadband access system, when data is received from the access device user with a search key demands of the last process, form selection criteria and search our database of static content transmission channels, base current dynamic content-channels (at the time of the search) and in the database content VoD or nVoD. The search results display the access device of the user. If the search results satisfy the user returns to the stage of the procedure call search. If the search results do not satisfy the user, form new criteria for finding similar content units. The criteria of similarity of form with the help of the user or on the basis of statistics taken from the database on the server services the core of the network, or receive from an external source, for example, together with metadata. Similarly, an operating system of the Apple Genius, which is component software iTunes® compan�and Apple Inc. In accordance with the new formed criteria again sample the transmission from the base static content channels from a database of current dynamic content-channels and content from the database VoD or nVoD.

According to Fig.7, Fig.8, the process of forming schedules data transfer dynamic content-channel and the formation and transfer of these data is as follows.

Dynamic content-channels are the content units of the length of a translation T, where T is the time interval that is transmitted to device groups user access in specific time intervals. The number and order of data transmission through dynamic content-channels are formed, respectively, the resources of the media content, and accordingly requests received from devices user access. These dynamic content-channels can be formed from the content of units that are sent from the base transmission static content channels, the base current dynamic content-channels (at the time of the search) and content from the database VoD or nVoD.

The device group user access can be formed according to any grounds, for example, the members of the social network, the inhabitants of one settlement, the employees of one company, students of the same class, etc.

an Example of the process of creating dynamic content-channels next. To access devices of users send data with the list of content units from the base of the static transmission of the content channels, the base current dynamic content-channels (at the time of the search) and content from the database VoD or nVoD, data and asks you to select a time interval T of the content units of permanent content-channel or dynamic content-channel or data services VoD and/or nVoD.

When receiving data that includes a request for selection in the time interval T content-units of permanent content-channel or dynamic content-channel or data services VoD and/or nVoD, carry out the formation and transmission from at least one device user's access to the core network and broadband access data on the user's choice.

Also carry out the formation of the database, e.g., server services, network core or to an intermediate device, which contains data for each of the identified users or for each group of identified users, which contains information about the users of the content units content-channels or VoD and/or nVoD, primarily, to determine the number of users with the same selection of content units in a time interval T on the basis of the created database.

Also set at least one limit �the value of N 1for the number of users with the same choice of content-units.

For example, at the end of the broadcast of certain content units or DC current dynamic content-channel users send a message containing a selection menu through which it is possible to choose to view another content unit in the next time period. The selection menu may contain a number of points relative to different time intervals. Users can choose from a suggested menu items or to refrain from choosing, in this case from the device for access users may not send any signal.

Thus, in the case of broadcast content units of permanent content-channel, the user can agree or disagree with the further transfer already on the schedule data or select from the list of content channels another content unit, for example, a television program.

Carry out the formation of the schedule data with content items of current dynamic content-channel and/or content units of permanent content-channel and/or the services of VoD and/or nVoD in accordance with data received from at least one access device of the user for at least one access device of the user or to the at least one group of access devices user�her.

To further analyze the results of the select users, calculated with the N(i)(where i is the parameter grouping users), for example, the number of users who chose the same content unit. Index N(i)compared with a fixed threshold N1for each i-th group. Also check an available channel resource of broadband access. In the case of N(i)>N1and in the presence of free reserves resource identifier for each content unit for which N (Ni)>N1, and broadcast information of such content units from the database of current dynamic content-channels. Can also try increasing the number of transmission data packets multicast and/or broadcast. Can also try increasing the number of multicast and/or broadcast mailings downflow channel broadband access with a content unit that elected the number of users N(i)greater than the boundary value of N1during the time interval t1<T<t2where t1- start of broadcast of the content unit that elected the number of users is greater than the threshold value, a t2- completion of translation of the content unit that elected the number of Paul�of obatala, greater than the threshold value, respectively, to the schedule.

Increase or decrease the width of the frequency band downstream channel broadband for content-unit, which is selected by the number of users is greater than the limit value, and/or multimedia data over the time interval T, can implement to optimize resource channel broadband access in case of use of the claimed method in the system high-speed wireless broadband access. In this case would be the energy resource of the downlink and uplink channels of the system. Down channel system is used for data transmission from the base station system (BS) to subscriber stations (MSS) according to the scheme of multicast. In this case, use the antenna that allows it to transfer data to multiple speakers simultaneously. In the opposite direction the speaker uses a rising channel to the BS, which transmit data packets, including data packets that correspond to user requests.

Thus, to increase the width (bandwidth) and/or number of channels of broadband access such a system, check the availability of a free frequency channel among the sectors of the antenna and use another frequency channel, if Nai�Yong free channel and free or backup transmitter.

Also given the fact that according to the modifications of the inventive method, provide a breakdown of the data blocks in the descending and ascending channels between the MSS and BS on N-blocks, for example, by providing a reserve amount of demodulators, i.e. those who are not involved in a specific time, enable the use of additional frequency channel of a certain sector in the case of increasing the number of data packets that need to be transferred between BS and SS.

When the broadcast content units, during the broadcast which was carried out a survey on a group of access devices send data in a content channel selected by the user. Ie, perform background, invisible to the user, switching the content of the channel according to its request.

At the same time for groups of users such that N(i)<N1send data that contain a menu with a proposal to obtain the content unit via VoD and/or nVoD at time t3or information about the availability of content units via VoD and/or nVoD at a later time t4.

If the access device the user has not received a response to the request, after the occurrence of time t2can send to the device data of the same constant content-channel and�and similar in some sense permanent content-channel or data content of the channel selected by most users at the moment and for which the increase in the number of transmissions of data packets multicast and/or broadcast downflow channel of broadband access.

After you perform a new regrouping of access devices users to send data with content-channels or VoD services and/or nVoD, carry out the reduction of the number of transmissions of data packets multicast and/or broadcast downflow channel broadband access at time tK, later than time t2the end of the previous broadcast content units. This release channel resource broadband access systems by ending the dynamic broadcast channel, assign the ID of this dynamic channel status unoccupied and sent back to base current dynamic channels.

Can also make the formation of a database on the server of the network core, which contains data for each of the identified users or for each group of identified users. The formation can be performed based on criteria such as:

- data about the query or the selection of content-units or content-channels or VoD services and/or nVoD;

data with feedback about the content unit or con�UNT-channel or service VoD and/or nVoD;

- data on the number and time of transitions between content-channels or VoD services and/or nVoD;

- multimedia data channel is sent through the system unicast or multicast.

During transmission of the data with content-channels or data services VoD and/or nVoD can transmit multimedia data channel. Such data may include background information or contextual advertising information to access devices of the user from the group of identified users, formed according to the statistics of the database. The purpose and content of these data have practical, aimed at a specific user or group of users in accordance with the information from the database statistics.

The use of the described method of allocation of channel resources in a broadband access system during data transfer, including multimedia data, is particularly effective for systems of high-speed wireless broadband access, for example, for such networks as LTE or BARS and the other with the constraint resource environment data, as described above, and to improve the optimization of channel resources broadband, to increase the degree of interactivity in the provision of multi-service data transmission services, particularly TriplePlay services, especially services like IPTV, as well as to simplify and reduce the costs of formation of the list of content units to send versus how it is performed according to the analogs of the present technology.
