The technical field to which the invention relates.
The present invention relates to the issue of allowing consumer access to the media product through connection digital subscriber line (DSL, DSL) and, in particular, is about allowing the user to quickly switch from channel to channel with the media product, provided through a DSL (digital subscriber line).
The level of technology
Twenty-five years ago the phone company used local telephone lines to provide voice communication services to customers. For entertainment consumers usually left the house, visiting cinemas, restaurants or parks. The main source of entertainment directly to the home was television broadcasting. Appeared the cable television industry, which primarily involved the installation of large antennas and connecting linear amplifiers to supply the received signals to many houses. At the same time, telephone companies were satisfied that their share in the market voice was undeniable. The operators of cable networks were too small and specialized to be interesting.
Today, the predominant service offered by telephone companies, still voice communication. However, the border between the cable industry and the telecommunications industry is erased. Cable companies are not focused on the delivery of entertainment media product. They, in particular, also provide data services through cable modems and demonstrate intent to compete with the telephone companies in providing voice communication services to domestic consumers.
With the development of communication technologies telephone wires and cable connections routed to the houses, almost ceased to differ from each other. What really distinguishes a separate wire from any other services that you can provide to consumers on this wire. In turn, the service that is provided over the wire determines its importance and value. The more services you can provide to the consumer over a single wire, the more valuable it is. Thus, suitable to house wires, separate for each type of service has lost its value, and the hour is about to be unnecessary.
Over time the point type/join to access home became less important than the services that this connection can provide. Although you can try to assess the problems of group psychology and human behavior to try to determine why there has been exponential growth mainly the entertainment industry (in the form of cable companies and Internet companies), it is not the purpose of this discussion. However, it is important to emphasize that the growing number of such companies indicates that expanding audience of consumers of mass market entertainment has led to the creation of a profitable and growing segment of the market. Observations have confirmed the emergence of cable and Internet companies, which, being small, has grown today to a huge conglomerates.
These observations revealed two aspects. On the one hand is the growing audience of consumers on the market of mass entertainment, delivered to the house. On the other hand - yourself entertainment played adequately important role in the emergence of an entirely new profitable sector.
Entertainment can be visual and acoustic, such as videos or movies. Pure visual entertainment can consist of books, magazines or Newspapers. Acoustic entertainment can include music, comments, news, and so what. The emergence of an open format for the exchange of visual entertainment via the Internet has become one of the cornerstones that underlie the emergence and consolidation of the market major providers of online services. In the above-described entertainment programs cannot distinguish between information and pure entertainment. The difference information from entertainment is more qualitative and subjective. Their share in the delivered volume is not necessarily different. Therefore, visual and acoustic entertainment together will be called a media product (audiovisual information).
Telecommunication companies to effectively compete for consumers in the future, should develop a compulsory set of services, including media products. The quality of these services should be at least no worse, and possibly better than similar services in other networks, for example, services provided by cable companies. The present invention was developed taking into account these and other considerations.
The present invention aims at eliminating the above-mentioned shortcomings, disadvantages and problems, and the idea of it is possible to obtain, after reading and studying the following description.
According to one aspect of the invention proposes a method for fast authentifizierung the th switching channels for the media product, such as video delivered to the consumer through a network Internet Protocol (IP). The invention allows to quickly switch channels with confirmation in the access node. An example of the access node is an access multiplexer digital subscriber line (DSLAM, MAZAL), which provides high-speed access to the consumer, which is the channel. Why channel may not be available to the consumer, can be commercial, that is, the consumer may not subscribed to the requested channel or not paid it. A possible reason could also be the lock acquired for the requested channel to limit its availability to the consumer based on time constraints or personal preference. For example, the consumer may not allow the child to watch a certain channel movies with scenes of violence.
According to another aspect of the invention features a method to allow quick access to at least one channel via an xDSL connection. To allow access to at least one channel in the base network using at least one multiplexer access to digital subscriber line (DSLAM, MDCL) resolution broadcast. To the core network via the xDSL connection is connected to at least one subscriber. In the multiplexer of MDCAL W is the group of broadcast request from the subscriber is received by at least one channel. Host MDCAL locally serves the xDSL connection for the subscriber. The information stored in the host MDCAL use to determine whether to allow the subscriber access to the requested channel. If it is determined that the subscriber is allowed access to the requested channel, MDCAL used to grant access to the requested channel on the core network with the installation of a single instance of each channel selected by subscribers.
Another aspect of the invention is to provide at least one broadcast Protocol (IGMP broadcast communication Protocol groups the Internet). Also, the subscriber can use the set-top box to provide xDSL connection, which is locally served by the host multiplexer of MDCL. In addition, the stored information may be included in the database of the host MDCAL.
Another aspect of the invention aims at providing each instance of each channel to the core network through a router connected to another network. To maintain the saved information, you can also use the remote (remote) processing. In addition, the remote processing can be used to update the stored information.
Another aspect of the invention relates to the access to the requested channel via an xDSL connection d is I the subscriber, which is locally served by the host MDCAL. The channel may include a media product (audiovisual information) for display, recording and playback using a set top box. In addition, the media product may include at least one of the following: video, graphics, images, text, talk shows and television programs.
According to another aspect of the invention for the practical implementation of essentially the same operations discussed above in connection with the description of the method, it is possible to use the device, system and media that is read by the computer.

Each exercise is described in sufficient detail to enable specialists in the art to implement the invention in practice, and you should understand that you can use other options, and make other changes, without going beyond being and scope of the present invention. Thus, the following detailed description should not be construed in a restrictive sense and the scope of invention is defined solely by the attached formula is subramania.
Throughout the description of the invention and its formula, the following terms are explicitly associated with them meaning, unless the context requires otherwise. The term "package" refers to the IP packet. The term "flow" means the flow of packets. The term "connection" refers to the flow or flows of packets that share a common path. The term "node" refers to a network element that connects one or more networks or devices. The term "user" refers to any person or consumer, such as a company or organization that uses the device for communication or access to resources across the network. The term "operator" refers to any technical personnel or organization that supports or maintains the network-based packages.
The term "router" refers to a specialized (dedicated) network element that receives packets and forwards them to the addressees. In particular, the router is used to expand or segmenting the network by sending packets from one logical network to another. A router is typically operates at level 3 and lower levels of the reference model of the interaction of the open systems interconnection (OSI) networking. However, some routers can provide additional functionality that are implemented above the level of the OSI reference model.
The term "xDSL" refers to any version of digital subscriber line (DSL DSL)service, which provides packet transmission between the modem end user and the access node, for example, the access multiplexer digital subscriber line (DSLAM, MDCL)connected to the core network. Version MDCAL include asynchronous DSL, synchronous DSL, high speed DSL, hybrid DSL, high speed DSL, etc.
The term "core network" refers to any digital network packet. For example, the System relay Frame Relay, Asynchronous transfer mode (ATM), switched Service multimegabit data (SMDS), etc.
The term "DSLAM" (MDCL) refers to the access multiplexer digital subscriber line, which is used for "splitting" of signals from multiple local loops xDSL, analog speech signals to the public switched telephone network (PSTN) and the data signals for the basic network.
The term "set top box" or "STB" refers to a device that allows you to turn the monitor display screen, TV, etc. in the user interface for a digital network, such as core network, the Internet, etc. the set-top Box also enables receiving and decoding digital programs broadcast for recording, playback and/or display.

Proposed method and system for fast channel switching of audio-visual information provided by companies house via the xDSL connection. Subscriber information of each user stored in MDCAL that supports xDSL connection going to the house. Also, each of MDCAL supports broadcast protocols, so that the network is only one instance of the channel, regardless of how many consumers have requested access to this channel.
When the consumer sitting at home, looking at audio-visual information on television, which receives radio signals from a terrestrial TV station, channel switching is performed quickly. Usually change channels occur within one second or less. When the user is watching a channel on TV that accepts a signal on a cable network, channel switching also be very fast. As a result, consumers expect a relatively quick response to their requests for channel switching. When the number of channels of audiovisual information is increasing, to provide the user the ability to quickly switch channels becomes more difficult.
Not all channels of audio-visual information is identical. Besides the obvious differences in subject matter and quality of programs, as well as individual differences, some channels are channels special demand. The TV special demand have different price structures for the consumer. This cost structure can be expressed in terms of different rates of subscription for a certain period of time (per week or per month), or that the viewer can make additional pay-per-view (pay per view for a special occasion). Other channels special demand can be combined with standard channels to create different packages or subscription levels. The combination of the set of channels is often called a package, and sometimes defined as the subscription level. The package can be a combination of any number of channels special demand and standard channels. Also some packages may not display the video.
To ensure collection of payments for service packages service providers typically use packet inspection services. For example, in the cable television industry this package test is called a conditional access system (CAS COURT). Another example is a smart card that is often used is implemented by service providers, delivering your packages descending satellite communication line. Checking packages are well organized in the cable television industry, as well as in the industry of satellite television. In the case of providing packages of cable television services the subscriber has the ability to quickly switch channels (channel "surfing", view), and the test can be carried out quickly and in real time. However, the packet inspection services in the telecommunications industry is not known.
Service providers in the form of audio-visual information for the effective use of wired or wireless access to the homes covered by the telephone network, you must have a system for checking packages. However, any system packet inspection services provided by the telephone network must process requests for channel switching as fast as terrestrial or cable television. For telephone networks popular option transmit audiovisual information to consumers are based network Protocol. Often the audiovisual information is transmitted by the circuit broadcast from one source in order to save bandwidth in the backbone network. The protocols of broadcasting on the Internet in detail is defined as an international standard Protocol management the ia group of the Internet (IGMP). See the documentation IETF RFC 2236, included here by reference.
Although fast channel switching can be performed using protocols IGMP, it is not always possible to quickly switch channels when the query user must first be authenticated and authorized. In the past, when the audiovisual information is distributed over a telephone network based on the IP Protocol using the methods of broadcasting, authentication and authorization are processed separately by initiating explicit calls sent to the agent or the authorization system application level. This individual processing was often made a significant delay in responding to requests to change channels from consumers.
Figure 1 gives an overview of an exemplary system 100 that allows the user to toggle/select media channels (channels with audio-visual information) using set-top boxes 110A-F through a telephone line xDSL. The multiplexers MDCAL 108A-C are connected to the core network 112 and support telephone line xDSL, which are connected with the corresponding locally-arranged set-top boxes 110A-F. In another network (not shown), the server 104 management programs connected to the router 106 and the server 102 management billing and subscribers. In addition, the type of audio-visual information provided by the channel, can the t to include, but not only: video, graphics, images, music, text, talk shows, TV programs, etc.
In figure 1 the consumer has requested/switched the channel using the box 110F. The request channel is taken along the line xDSL multiplexer of MDCAL S and sent to the server 104 program management for core network 112 via a router 106. The server 104 program management processes the request by allocating identification numbers (ID) of the consumer and other characteristics of the query. The server 104 control program sends a request to the server 102 management billing and subscribers to check the request for the channel from the consumer. The server 102 management billing and subscriber determines whether the consumer is entitled to receive the requested channel, and sends a response to the verification server 104 management programs, which either meets or does not meet the request for the switch based at least in part, the content response with the validation result.
Also, if a request for a channel is enabled, the server 104 management programs will provide audiovisual information for the requested channel in MDCAL S, which then takes audiovisual information requested channel to the set-top box 110F. Alternatively, if the server 104 program management rejected C the question, then audiovisual information is not provided in MDCAL S that locally maintains the consumer requesting the selected channel using the set top box 110F.
Temporal parameters associated with the above-described process include: TCthe time needed by the consumer device (set top box) to make a request; TCDthe time of transition from consumer to MDCAL; TDPthe time of transition from MDCAL to the management server programs; TP- processing time in the server management programs; TPBthe time of transition between the management server programs and server data processing in the accounts and subscribers; TB- processing time in the processor for data processing in the accounts and subscribers; TBPthe time of transition from B to P; TPDthe time of transition from P to D; TDCthe time of transition from D to C; TCSthe time required (the consumer) for the organization of the action taken as a result of the response. Thus, the total time required to satisfy the request of the consumer, will be:
Alternatively, the program guide (control programs)that are displayed to the consumer, can accommodat is to provide for a choice of channels, recourse to which was confirmed in advance. Therefore, any request that comes from the consumer, can be considered legitimate. In this case, the total required time is given by the following equation:Talternative=TC+TCD+TDC+TCS.
In this equation also has two assumptions. Firstly, MAZAL is a multiplexer with a resolution of broadcasting, or in other words, in MDCAL available broadcast channel. If MDCAL broadcasting is not authorized, then the request should be passed on down to the management server software or the reception point of the video. In this case, the total time increases to TC+TCD+TDP+TP+TDC+TCS.Secondly, the management server software can remotely manage consumer device by sending updated information without a request from the device user.
The invention improves the previously used technical solutions in at least two ways. First, each of MDCAL allowed to broadcast using IGMP. Secondly, requests for channels from consumers checked locally in MDCL, the technician set-top box.
On figa shows the example system 200, which demonstrates at least some of the s disability associated with the use of multiplexers MDCAL A-without broadcasting. The system 200 allows the user to toggle/select channels of audio-visual information via the set top box 204 via the telephone line xDSL. The multiplexers MDCAL A-without broadcasting connected to the core network 208 and support telephone line xDSL, which are connected with the respective local set top box 204. In another network to the router 202 and the server management billing and subscribers connected to the management server software. Although not shown, these servers are actually in the same manner as discussed in connection with figure 1.
Bandwidth for audio-visual information from another network (not shown here) to the core network 208 at the point of reception of audio-visual information, that is, the router 202, is directly proportional to the number of consumers requesting a channel from their set-top boxes 204 via respective multiplexers MDCAL A-C. Even if two consumers served by the same multiplexer of MDCAL without broadcasting, has requested the same channel, each consumer to view this channel set independent channels through the underlying network. In this case, for each request, the consumer must be installed to a separate channel, for example, for six comp the computer consoles, connected to the core network through MDCAL without broadcasting, the router 202 will need to have a capacity for six channels, even if each box has requested the same channel.
The equation expressing this relationship is as follows
(Core Network Utilization)NOMULTICAST_DSLAM∝ The number of Active Consumers
(Basic network)without _DSLAM∝ number of active consumers
On FIGU shows the approximate system, where the multiplexer of MDCAL allowed broadcasting. An exemplary system 220 allows the user to switch/select channels of audio-visual information via the set top box 224 via the telephone line xDSL. The multiplexers MDCAL A-resolution broadcasting connected to the core network 228 and support telephone line xDSL, which are connected with the respective local set top box 224. In another network (not shown) to the router 222 and server management billing and subscribers connected to the management server software. Although not shown, these servers operate in much the same way as discussed in connection with figure 1.
In this embodiment, there is no duplication of channel traffic through the core network 228. Instead, the multiplexers MDCAL resolution broadcast interrupt the connection for each ka is Ala in the core network 228, and then process the broadcast requests from consumers (set-top boxes, 224), which they serve locally. Thus, the bandwidth at the point of reception of audio-visual information, i.e., router 222 and core network 228 is directly proportional to the number of available channels. For example, if the core network via the multiplexers MDCAL resolution broadcasting connected six set-top boxes, and each box asks for only one of the two different channels on the router 202 to provide audio-visual information to the set top box 224 will be required bandwidth for only two channels.
The equation expressing the operation of this variant is as follows:
(Core Network Utilization)MULTICAST_DSLAM∝ The number of Available Channels(basic network)_DSLAM∝ the number of active channels
Usually the Number of active users (The number of Active Consumers)≫ Number of active channels (The number of active Channels)
Figure 3 shows the combination of both improvements (first and second), proposed in the invention. In particular, the second enhancement allows verification (authentication/authorization) requests user of the set top box at a local technician of MDCAL resolution broadcasting (supports IGMP). banatska information information about Bank accounts and additional information related to the user, is stored locally in MDCAL resolution broadcasts. This information, in combination with means for broadcasting in MDCAL allows you to quickly assess the request for channel switching from the consumer, and, if the query is confirmed, then almost immediately available audiovisual information, which is reproduced on the requested channel.
Figure 3 provides an overview of an exemplary system 300 that enables the user to toggle/select channels with audiovisual information using set-top boxes 310A-F phone line xDSL. The multiplexers MDCAL A-resolution broadcasting connected to the core network 312 and support telephone line xDSL, which are connected with the respective local set-top boxes 310A-F. In another network to the router 306 and the server 302 management billing and subscribers connected to the server 304 management programs. These servers operate almost the same way as discussed in connection with figure 1, except that they load the information needed to verify and authorize the request for channel switching, each of MDCAL before the query.
In this embodiment, a request to switch channels from a set-top box 310F applies only to the mul is plexor of MDCAL S resolution broadcasting, providing local service. Basic network 312 must provide only one copy of each requested channel instead of separate channels for each authenticated and authorized request.
Thus, the total time of switching channels for the variant shown in figure 3, can be expressed by the following equation:
Although the total processing time of the request for channel switching can sometimes be close to the total processing time on a number of the methods mentioned above, the invention removes at least three weaknesses existing in the above-described methods. In the invention, the data consumer/subscriber, used for authentication/verification, load only to MDCAL. MDCAL supported and managed by a service provider, such as the telephone company. Consumers do not have access to this information or to the management interfaces for MDCAL. Therefore, it is difficult unlawful to change or access this information for unauthorized access to audiovisual information.
In contrast, in the previous methods the data used for authentication/verification and authorization for switching channels loaded in the device, such as a set-top box, nah desousa in the home of the consumer, that increases the likelihood of attack from hackers and/or unauthorized switching. In this case, an unscrupulous user (hacker) can use the methods of unauthorized access, such as vingiani channel (channel sniffing). When vingiani channels" hacker activates a program that gives the right to view requests for channel switching, using a properly installed protocols are broadcast in the hope that at least one of the requests will ask the right set of channel identifiers. If there is sufficient time, the hacker can figure out the correct channel identifiers. In addition, if MDCAL does not validate requests for channel switching, it will respond to any request with the correct data. Thus, the invention can reduce the number of attempts to "vingiani channels", etc.
In addition, previous methods were based on the user ID stored in the device, such as a set-top box in the home of the consumer. This approach is not reliable, because this information may be false. In contrast, the invention features authentication/verification of customer information based on the access port in MDCL. Since the service provider maintains information about the ports access the PA, it is easier to accurately establish the relationship between service subscription and the particular location of the consumer.
Figure 4 gives an overall view 400 of one variant of the invention, which includes at least two software components: module 402 authentication, which is performed in MDCAL 414 resolution using IGMP, where this module authenticates requests for customer service; and module 408 operation support system (OSS STRs), which supports update data for authentication of the user stored in MDCAL 414, and is in communication with a remote application that handles authentication data for each MDCAL in the core network (not shown, but essentially similar to the system shown in figure 3).
Figure 4 shows that MDCAL 414 receives a request for audio-visual (video) channel from the set top box (STB TA) 404 in the form of an IGMP query. In this example, the monitor 406 is connected to the TA 404 for playback of audio-visual information (video) product on the requested channel. To TA 404 is also connected audio interface 412 to audio signals via the requested channel.
After receiving the request for switching channels MDCAL 414 performs parsing and uses module 402 authentication to perform the search in the database 410 for authentication on the new IP address of TP or a suitable identifier of the consumer, such as a port identifier, and a broadcast channel address included in the content request. It can be assumed that the device ID of the user is correct and unique. This information is checked in near real time by matching with the ID of the STB (e.g., the address of the access Protocol environment) and information on the profile of audiovisual services stored in the cache memory of MDCAL 414.
If the consumer is allowed the reception of the requested channel, the STB TA 404 will be provided a copy of this channel, while at other times you do not select a new channel. If a customer is not subscribed to the requested channel may be provided with a common message about the denial of service. In most cases, the transaction time from TA to make a request channel and a response sent back by the multiplexer of MDCAL will be less than 250 milliseconds when using the present invention.
As implied above, the privileges of the user on the channels will be stored in the cache memory of the multiplexer of MDCAL 414 resolution broadcasts. In one embodiment, the invention can provide an interface with the upper level system, documented according to SNMP (simple network management Protocol), which allows the application of str 408 to maintain the reliability of you who upomanutoi information. This variant is capable of maintaining the specified information for each TA. Changes to such information can be maintained during run-time, and this information can be stored in the hash table to maintain a high speed retrieve information.
As a component of str is usually located at a distance, updates may come in MDCAL with each change of subscription for each user. In most cases, the service provider wants to distribute changes to your subscription to the multiplexers MDCAL in the underlying network in near real time. Therefore, when the user requests a new subscription to the channel or cancel an existing subscription, component STRs can immediately provide these changes in MDCAL in the underlying network, which serves locally TS the consumer. It is clear that the remote application STRs can send messages about changes on the basis of SNMP requests in MDCAL for processing.
In one embodiment, the module STRs and/or the remote application can be written in the programming language "JAVA" to run in a virtual environment JAVA. In another embodiment, the implementation module authentication based MDCAL is written in the programming language and runs on the operating system of MDCL.
Figure 5 gives a General idea about 500 operations of modulememorysize. From the initial stage, the process goes to step 502, where the authentication module based MDCAL parses the request for channel switching request (IGMP)taken from the locally accepted set-top boxes in the home of the consumer. The process then passes to step 504, where the authentication module performs the search function in the subscriber database stored in MDCAL that locally maintains the set-top box. Next, the process goes to step 506 decision where you determine whether the authentication module a request for the channel, based on at least part of the privileges of the consumer, included in the locally stored subscriber database. If a negative decision, the process proceeds to the end step and returns to processing other operations.
However, if at the stage of decision 506 issued a positive decision, then the process continues to step 508, where the resolution on the provision of consumer audio-visual information on the selected channel. The process then passes to step 510, where the authentication module asynchronously receives updates the subscriber database, provided by the module STRs. Next, the process moves to the final stage and returns to processing other operations.
6 gives a General idea about 600 operations performed by the module STRs. From the beginning of the high phase, the process goes to step 602, where the module str asynchronously supports each subscriber database, stored locally in MDCL. The process continues to step 604, where the module SPO provides each subscriber database based MDCAL update the subscriber when adding, changing or removing characteristics of media services. The process continues to step 606, where the module str asynchronously checks the subscriber data stored in the subscriber database in each of MDCL. Next, the process moves to the final stage and returns to perform other operations.
7 gives a schematic overall view of an exemplary device (TA) 700. The power source 720 provides the electric power required for operation of each component included in the TA 700. Bus 710 provides the ability to share signals of several components, including random access memory (RAM) 702, a persistent storage device (ROM) 704, audio interface 706, the interface 708 output interface 716 memory controller interface 714 and 712 for xDSL. Programs and data to control the operation of the TA 700 may be stored in the RAM 702, a ROM 704 and/or the storage device 718 connected to the interface 716 memory. Although not shown, the interface 712 for through xDSL xDSL circuit connected with local service multiplexer of MDCL. Audio interface 706 can and shall be used for playback and/or recording at least audio information, contained in the channel selected by the operator/user.
Interface 708 is used to output video signals contained in the channel selected by the operator/user. The output signals can be provided in any of a number of known formats for playback on the display device, such as a monitor, display screen, TV, etc.
On Fig schematically shows an exemplary multiplexer of MDCAL 800. Interface 806 core network is used for communication essentially the same underlying network, which was discussed above and is discussed below. Many set-top boxes (see Fig.7) can be serviced through the interface 802 for xDSL, which is connected to the local (closed) xDSL circuits for each consumer. Module 810 authentication performs essentially the same operations discussed above and discussed below, and is connected with the interface 802 for xDSL, the system controller 812, a subscriber database 814 and module 808 access to audiovisual information. The function of each components of MDCAL 800 and their interaction helps to ensure the functionality of broadcasting and local authentication requests for channel switching consumers, as discussed above and discussed below.
