The invention relates to a multi-channel digital television, in particular aspects related to navigation channels. The proposed system television differs in that the right of access to a program or channel are received and analyzed by the decoder, which determines whether to allow or deny full audio and visual user access to the program or channel displayed in a window mosaic patterns. 2 N. and 78 C.p. f-crystals, 15 ill.

The invention relates to a multi-channel digital television, in particular aspects of the system related to navigation channels.

One of the advantages of digital television, is the number of channels available in such systems, as well as the flexibility provided by the television service provider in respect of the selection of channels that can be offered to the subscriber. In addition to the standard set of subscription channels, the system may include other channels with controlled access, such as, for example, a channel with pay-per-view (PPV channel), allows subscriber to pay for the viewing of any particular movie, sports, etc.,

Yunogo nature, such as text listings, maps, weather, etc., These services can be associated with specialized digital channels used to transmit information. You may also have other services, use the advanced menu provides the user access to some basic information through a series of drop-down menus while watching a broadcasting program. These services operate using the so-called "pilot" the information transmitted on the same channel as the usual audio-visual channels.

Although the audience benefits from a wider range of available options, a large number of available channels and services can be confusing, and in practice for the viewer using the variety of opportunities is often difficult. In addition, existing navigation AIDS are often unable to correctly organize the interaction between the navigation means and channels with controlled access, some of which may not be available for this user.

The purpose of the present invention in its broader and/or more specific aspects to overcome some or all of these disadvantages, and to facilitate navigateuri aspect of the present invention is proposed a decoder to control the display of multiple digital TV channels in the boxes, included in the mosaic structure, which includes a means, such as an interface, for receiving access rights to a certain program or a certain channel and a means, such as a Central processor, to prohibit, in accordance with said received access rights, full audio and visual user access to the said program or said channel when it is displayed in the above window.

Use display the available channels in a mosaic format to facilitate navigation through channels known in the art. However, such a mosaic tools allow the user full access to all available channels, albeit with a reduced image. If the digital sound for this channel is also available, the user can view and listen to in full, for example, usually only available by special subscription or payment, but shown here in one of the Windows of the mosaic image. The present invention solves this problem.

This aspect of the present invention extends to a system of digital television that contains the decoder is configured to display multiple digital TV channels in order to solve or prevent full audio and visual user access to this program or this channel when it is displayed in a window mosaic patterns, taken and analyzed by the decoder.

The above-mentioned decoder preferably includes means for receiving data access rights together with the audiovisual data to guide these mosaic patterns. In order to make possible for the user to purchase the full rights to the program and/or channel, the decoder preferably includes means for issuing a request for full audio and visual access to a certain program or a certain channel, displayed in a window.

Said data access rights can be used by the decoder in several ways. For example, in implementations in which to select the desired channel is used the cursor and the audio information generated by the decoder in response to the positioning of the cursor, the decoder may be configured to enable or disable the generation of audio information for a program or channel with controlled access.

Accordingly, the decoder preferably includes means for generating a cursor displayed in said mosaic structure, which can be selectively navigate through the Windows mentioned mosaic patterns, objectsto for generating audio information, associated with some particular channel in response to the positioning of the above-mentioned cursor on the window that displays referred to a specific channel, and may also include means for prohibiting generation of the mentioned audio information in accordance with the above adopted access rights.

Audio information may be blocked programs or channels with controlled access, for which the decoder does not have appropriate access rights, constantly. Alternatively, the audio information may be blocked when the cursor is positioned on the banned box mosaic patterns longer than some preassigned period of time. Accordingly, the said prohibiting means may be configured to prevent generation of the mentioned audio information when the cursor is positioned at the window longer than some preassigned period of time.

In yet another variant implementation in dependence on the access rights associated with the program or channel that is displayed in this window can be supplied with the interaction of the cursor with window mosaic patterns. For example, the decoder can be performed with vozmojnoe mosaic patterns, corresponding to a program or channel with controlled access. Accordingly, the decoder preferably includes means for automatically changing the position of the cursor if the cursor is positioned on the window that displays a certain program or a certain channel, which denied full audio and visual access.

This change of position of the cursor can be performed instantaneously, so that the decoder does not allow you to place the cursor directly on any program or channel with controlled access that is displayed in the window mosaic patterns. Alternatively, change the cursor position can be performed after some preassigned period of time. Accordingly, the said means for changing the position of the cursor is preferably made with the possibility of changing the position of the cursor after some preassigned period of time. In the case when, for example, when selecting the appropriate window with the cursor is activated sound, this time delay allows the user some time to have full access to the code, allowing the user evaluations from the rights of access to the program and/or channel, displayed in a window. For example, in addition to the above operations, or alternatively, the decoder may include a means for automatically changing the position of the cursor after some preassigned period of time. This may provide the user the ability to "surf" on the mosaic image, receiving in turn during this preassigned period of time of the audio information for each window of this mosaic image. This mode of operation ("surfing") can be enabled by pressing special keys on the remote control.

Alternatively, change the cursor position after lapse of a preassigned period of time referred to the decoder can be performed with automatic prompting for full access rights to a certain channel and/or program to which the full audible and visual access is denied, if the location of the cursor on the window displaying the above-mentioned channel and/or program, for some preassigned period of time. This can be provided the ability to automatically order the rights Poltrona user.

In addition to the operations described above, or alternatively, the above-mentioned decoder may be configured to generate a message informing the user about the lack of access to a program or channel when positioning the cursor on the forbidden window mosaic patterns. Accordingly, the decoder may include a means for generating a message informing the user about the access rights to a certain program or a certain channel when positioning the cursor on the window displaying the program or referred to the channel.

Alternatively or additionally, the decoder can simply disable the generation of video data in a window mosaic patterns depending on the access rights associated with a particular program or channel, under normal conditions displayed in this window. Accordingly, the decoder may include a means for prohibiting generation of at least part of the video information in the above box, depending on access rights to the program or channel that is displayed in this window.

This additional videos may contain promotional information, such as the announcement of some future program, which must be shown on the channel displayed in the window.

Access rights to a program and/or channel typically contain information about the type of this program or channel, such as, for example, whether the channel podminirane or deny full audio and visual access to the program and/or channel, displayed in a window mosaic patterns, these and other access rights can also be used by the decoder to configure the various settings of the image.

For example, the decoder may include a means for changing some attribute of the above-mentioned cursor depending on some characteristics of the at least one program or channel is displayed in the window, on which the cursor is positioned. This characteristic may include, for example, the category of the program (such as "only for adults" or "children's program"), theme of the program (e.g., sports, wildlife, politics) whether the program transfer with pay-per-view, etc. in Addition, programs and/or channels can be divided into groups in accordance with a user selection, for example, a group of "favorite" channels, and these attribute cursor changes accordingly each time when positioning the cursor on a window, display one of your favorite channels of the user. This can make it easier for the user identification of channels and programs that are displayed in a mosaic structure.

Accordingly, in accordance with another aspect of this image is appropriate boxes, included in the mosaic structure comprising means for generating a cursor displayed in said mosaic structure, and mentioned the cursor can be moved across this mosaic structure to select the desired channel, and means for changing some attribute of the above-mentioned cursor depending on some characteristics of the at least one program or channel is displayed in the window that contains the cursor.

The overall structure of the digital television system 1 in accordance with the present invention shown in Fig.1. This invention includes almost normal system 2 digital television, using known compression system MPEG-2 to transmit compressed digital signals. In more detail, the MPEG-2 compressor 3 in the broadcast center receives a stream of digital signals (typically a stream of video signals). The compressor 3 is connected to the multiplexer and scrambler 4 using the communication channel 5.

The multiplexer 4 receives a lot of additional input signals, assembles one or more transport streams and transmits compressed digital signals in the transmitter 6 of the broadcast center via a communication channel 7, which, of course, may be different, including telecommunication lines. The transmitter 6 transmits electromagnetic signals through the channel Ground-to-satellite 8 JV is anal "satellite-to-Ground 10-ground receiver 12, usually having the form of plates, belonging to the end user or rented them. The signals received by the receiver 12, are transmitted in a combined receiver/decoder 13, owned by the end user or rented by him, and is connected to the TV 14 end user. The decoder 13 decodes the compressed MPEG-2 signal in the television signal to the television 14.

Of course, other transport channels for transmitting data, such as TV terrestrial broadcasting, cable transmission, combined satellite-cable TV, telephone networks, and so on,

In a multichannel system, the multiplexer 4 handles audio and video information received from multiple sources, and communicates with the transmitter 6 for transmitting this information to the appropriate number of channels. In addition to audio-visual information in some or all of these channels can be entered messages, or applications, or digital data of any other type, alternating with the transmitted digital audio and video information.

System 15 conditional access connected to the multiplexer 4 and the receiver/decoder 13 and is located partially in the broadcast center, and partly in the decoder. It allows the end user is amnic/decoder 13 can be installed smart card, able to interpret the messages related to the commercial offerings (i.e., to one or more television programs that are sold by the broadcast network operator). Using the decoder 13 and the smart card end-user can buy transmission mode subscription or pay-per-view (PPV).

As mentioned above, the program transferred by the system, scribblenauts in the multiplexer 4, the conditions and the encryption keys used for this transfer are determined by the system 15 access control. Such transmission scrambled data is well known from the field of pay-TV. Usually scrambled data is transmitted together with the word control to diskriminirovaniya these data, and the control word is encrypted by using the so-called working key and transmitted in encrypted form.

Then scrambled data and the encrypted control word is accepted by the decoder 13, having access to the equivalent working key stored in the smart card installed in the decoder for decoding the encrypted control word and the subsequent diskriminirovaniya transmitted data. Paid for a subscription, the subscriber receives, for example, in the monthly peredavai the encrypted control words, what you need to watching.

Interactive system 16, also connected to the multiplexer 4 and the receiver/decoder 13 and is also located partially in the broadcast center, and partly in the decoder, enables the end user to interact with various applications via modem back channel 17. The modem back channel may also be applied for the implementation of transmission used by the system 15 conditional access. The interactive system can be used, for example, to enable the user to communicate directly with the transmitting center to request authorization to view a particular event, the application is loaded, and so on

With reference to Fig.2, will be described below, the elements of the receiver/decoder 13 or user consoles. The items shown in this drawing, will be described as functional blocks.

The decoder 13 includes a CPU 20, with the respective memory elements, and is configured to receive input data from the serial interface 21, a parallel interface 22, a modem 23 (connected to the modem back channel 17 shown in Fig.1) and the switching contacts 2 the ACLs of the input signals from the remote control 25 remote control means 26 controls and is equipped with two devices smart card reader (27, 28), is performed with the read Bank cards and subscription smart card, respectively. The device 28 reads subscription smart card communicates with the established subscription smart card and means 29 conditional access for issuing the word you want to control the demultiplexer/descrambler 30, making possible diskriminirovaniya encrypted broadcast signal. The decoder also includes a conventional tuner 31 and demodulator 32 for reception and demodulation of satellite transmission before filtering and demultiplexing in the tool 30.

Data processing in the decoder is usually performed by the CPU 20. When accepted audio and video, MPEG packets containing these signals will be demultiplexor and filtered in such a way as to transmit audio and video data in real time in the form of a packetized elementary stream (PES) audio and visual data in specialized processor of the audio signal and the video processor or the decoders 33 and 34. The converted output signal processor 33 of the audio signal enters the amplifier 35, and then the audio output of the receiver/decoder. The converted output signal of the video processor 34 receives che the processor 36 preferably has a capability of forming a display image, combining moving images with superimposed over the text or other images. More specifically, it can combine four layers: a layer of still images, the layer of moving images, the graphic layer and the layer of the cursor. The GPU 36 optionally accepts graphic data to be displayed (for example, the generated image, and so on), from the Central processor 20, and combines this information with information adopted from the video processor 34, for forming a display image.

Software architecture Central processor can match the one used in a known decoder, and will not be described here in detail. Its Foundation can be, for example, the virtual machine that communicates via the interface level with the operating system of the lower level, built-in hardware decoder. In terms of architecture the hardware decoder will be equipped with a processor, memory elements, such as ROM, RAM, flash memory, etc., as known decoders.

The Central processor 20 can be configured to run multiple applications that define the functionality of the decoder. Priaulet, for example, higher-level functions of the machine. Typical applications may include forming a sequence of graphical objects on the TV screen in response to a command from the remote control or send a message through the modem decoder in the server digital broadcasting system.

As will be described below, according to the present invention is a application designed to generate display images, cursor, and information about programs that overlap or replace normal TV picture, and navigating through multiple channels or interactive services offered by this system. The displayed information may include substantially unchanged data menu and/or data which is updated using the information contained in the MPEG transport stream in one or more channels.

Applications can be a self-hosted application, stored in ROM or flash memory of the decoder, including any attachments, sent or downloaded via the MPEG decoder interface 20 or, indeed, any other interface decoder, such as a serial interface 21, the device 27 smart card reader, etc. Applications m is ment for T-Commerce (shopping), as well as the initialization of the application, allowing the decoder immediately after turn on go to the operating state, and the application to configure the decoder.

Applications are stored in the memory cells of the decoder and are represented as resource files, including files descriptions of graphical objects, files, libraries, files, blocks, variables, files, sequences of commands, files, applications, data files, etc.

Applications typically loaded into the decoder via a broadcast channel, divided into modules, where each module corresponds to one or more MPEG-tables. Each MPEG-table can be divided into several sections. In the case where data transfer is also carried out via the serial and parallel ports, modules can be also divided into tables and sections, and the size of the partition depends on the channel used.

In the case of transmission by broadcasting the modules are transmitted in the form of data packets, data streams of the respective types, such as video data, audio data stream, a stream of textual data. In accordance with MPEG standards, each packet is preceded by a packet identifier (PID) with a length of 13 bits, one PID for each packet transmitted in the MPEG data stream. For certainly the different data streams for that channel, and determine the contents of each stream, using a reference to its corresponding PID. Access to the table or tables RMT is through the main table access programs (PAT).

In the system of digital broadcasting information is transmitted on multiple frequency channels, having beforehand set constant throughput. One frequency channel may include multiple streams of audio and/or video data. For example, one data stream may be associated with multiple streams of audio data synchronously sounding program in several languages. In alternative or additional features in the stream of packets corresponding to a given frequency channel can contain multiple video streams, showing, for example, the same sporting event with the positions of several different cameras. Although these different streams of audio and video broadcasts on the same frequency channel, the viewer can perceive the transition from one stream of audio/video data of this frequency channel to another as the corresponding physical channel switching.

In addition to the normal audiovisual records programs on the frequency channel can be transmitted and other data. As will be described below, programs, etc. The PID values for such data can also be accessed through the table RMT.

In order to ensure consistent interface, some information should be broadcast on all frequency channels. For example, data associated with an application type of "Pilot", which includes basic information about the program and available for the user to choose the options that can be passed on all frequency channels, so that the user can always access this information, regardless of the preview program or channel. This ensures the integrity of the interface.

With reference to Fig.3, will be described below controls panel 25 remote control for the receiver/decoder. This structure of the remote control corresponds to the control panel, supplied together with the existing digital dekodery system Canal+Mediahighway. It is clear that the response of the decoder to the involvement of a particular organ, TV remote control is programmable and may be different depending on the applications loaded in the decoder. Thus, although certain functions (on/off, beep suppression (mute), and so on) are universal, others may change program has a key PROG (40) and press PILOT (41). In existing digital dekodery system Canal+ Mediahighway these keys are called, respectively, the program guide, which lists programs available on each channel, and the application-pilot, providing information about the program that the user is looking at this channel, as well as certain information about other programs that should be on this and other channels at this time, in the near future, and so on,

In the proposed version of the application pressing the PROG (40) on the remote control will call the main service menu of a more General plan, and referred to the program guide is available as one of the items of this menu, along with other services, such as interactive applications for shopping, etc. the Application by pressing PILOT (41), remains largely unchanged.

The console is also equipped with a group navigation pointing direction keys 42, to control the movement of the screen cursor in the OSD menu, and click "OK" ("Confirmation") 43, to select the item selected with the cursor.

Group 44 numeric keys provides the possibility of direct selection with some room to kultovitsa to enter additional data, such as days of the week, day/night/evening, etc., These data can be written above the keys and can be used when programming the application timer, when navigating the program guide, etc.,

Remote 25 remote control is further provided with a key 45 preferences, providing access to a menu with a list of a limited number of preferred channels selected by the user. This way the user can quickly switch between channels, which he sees most often. Key 46 is used for output from the activated application or the OSD menu.

Key SERV (47) is used to retrieve information about the services provided by the activated application, such as user manuals for the application shopping.

Key "+" (48) provides access to menus that allow you to choose subtitles in one of several languages and/or to choose the language used in the sound of the displayed program.

Key PERSO (49) invokes the application that allows the user to configure and customize some of the basic functions of the decoder, including the volume level of the sound from the audio decoder, the video signal from the video decoder and so on

To ofany specific applications and at the discretion of the developer to cause a specific action, such as the return to the previous menu, etc.

Finally, the key 51 suppression sound signal enables or disables the sound that accompanies the display channel button (TV/SAT (52) allows the user to switch from channels received via satellite input to the channels received through the broadcasting antenna, and the 53 "sleep mode" provides the user the ability to remotely activate and deactivate the decoder.

Please refer to Fig.4; one of the services offered is the "lattice" or the mosaic structure (education), showing the content of the channels received by the decoder. In response to the selection of this service, the decoder switches to the frequency channel associated with this service and then displays the mosaic image 80 shown in Fig.4. In this embodiment, the implementation of a mosaicked image 80 is broadcast on channel 8 and, thus, when the remote control press the number key "8", the decoder is tuned to this frequency channel. In alternative implementations, the remote control may have a special key for the settings on this frequency channel.

An image mosaic (mosaic) 80 consists of multiple Windows 81 with umeno some channel, and each window is provided (position 82) indicating the name of the channel that is shown in this display window 81. The mosaic image is also equipped with General information line 84.

Performed in the decoder application forms the floating cursor frame, shows the position 83. This cursor can be moved in horizontal or vertical directions using the navigation keys of the remote control. For example, in Fig.5 the cursor 83 is positioned so that the selected third and bottom third side window. Program name displayed at this time on this channel is displayed in the information line 84. The advanced decoder selects and reproduces the audio data stream associated with this channel. Pressing "OK" on the remote control causes the setting of the decoder to the channel displayed in this window.

In the mosaic image shown in Fig.4 shows 20 channels. In practice, the decoder can be made up to 60 or more channels. In this case, you may have access to other mosaic images with the programs. For example, if the cursor is placed on the window 84 shown in Fig.4, pressing the directional key right navigation arrow will cause perekhodtsev in the left part of the screen 80, pressing towards the left navigation arrow will cause the switching of the screen to another mosaic image with the programs. Screens mosaic display can also be looped, so that the output of the last tile of the screen will bring the user back to the first screen and so on

Mosaic image with the programs shown in Fig.4 shows a sampling of all channels, which are broadcast program for a given decoder. However, in some cases, the decoder may not have full access to all channels. For example, some channels may be allocated for PPV programs, or may require additional subscription by the user. In this case, it seems undesirable that the user had full access to audio and video data of the program, even for versions with a reduced screen image displayed in the display Windows 81.

Accordingly, in one embodiment, the implementation decodeme application which controls the display mosaic image made with the possibility of tracking time during which the cursor frame is in the same position. After a certain period of time, such as 30, this PR is the user entitled to full access to the program or channel, displayed in this window mosaic patterns.

In that case, if the decoder does not have the necessary access rights, the application can disable the sound signal output after the expiration of 30, so that the user will no longer be able to hear the sound of this program.

In that case, if the user does not have the necessary access rights, the cursor frame is moved to another window this mosaic image, such as the first element in the upper left corner of the first screen. Alternatively, the cursor may move to a window of another mosaic image. Over the next 5 min or so the application may not allow re-place the cursor in this window with disabled access.

In this case, the application may prompt the user to pay for access to this channel, as shown at position 86 in Fig.7. If the user agrees, the application can immediately switch to this channel using, for example, pre-paid "tokens" that are stored in the subscription card user. In alternative implementations of the present invention, the application can activate the menu screens of payment used for subscription by the user. Mostly saddle acquired, the controller 20 may, running some application, to generate an animated image or an icon symbolizing the purchase of transmission. For example, the controller can generate an animated image of a shopping cart, which begins to fill as buying gear.

Alternatively, the actions performed after some time, the application can take the necessary actions to move the cursor and/or disable the beep, immediately after stopping the cursor on the window for the program or channel, the access to which is denied.

Not necessarily change the cursor position should depend on access rights to the program and/or channel displayed in a window. For example, in addition to the above operations, or alternatively decodeme the application can be configured to automatically change the cursor position after lapse of a preassigned length of time. This may provide the user the ability to "surf" on the mosaic image, receiving in turn during this preassigned period of time of the sound information for the special keys of the remote control.

Alternatively, change the cursor position after lapse of a preassigned length of time, the application can be performed with automatic prompting for full access rights to a certain channel and/or program to which the full audible and visual access is denied, if the location of the cursor on the window displaying the above-mentioned channel and/or program, for some preassigned period of time. This can be provided the ability to automatically order full access rights to a particular program and/or channel without the need for any additional operations by the user.

In addition to disabling the output sound signal or instead, the application can disable the video output. In some cases, for example if the displayed transfer "for adults", the decoder can always "score" output video and audio signals for a given program or channel, so that the lines 84 and 82 displays only the information of channel names and program. Since such material may be removed from all mosaic images regardless of the permissions of this decoder, this operation can b the em described the architecture of the elements of the transmission system, associated with the formation of the mosaic channel. Video sixty channels are accepted by the server 90, associated with the station 91. The server 90 performs the filtering those signals that should not be included in the mosaic image, for example, video signals associated with the channels "for adults only" and so on, Then the processed signals are sent to the processor 92, which changes the size and placement of the video signals within the display image so as to create three "grid", or mosaic screen shown position 93, which are then sent to the multiplexer 4.

Similarly, the audio signals of each channel are filtered (item 94), and shall be arranged and marked by the values of the PID (position 95), and then served in the multiplexer 4.

In addition to broadcasting audio and visual data that injects CA/DA-server 96 and its associated workstation 97 can add additional data. In particular, the server and the station add configuration data that defines the configuration elements of the mosaic image, and pilot data containing minimal information about the programs broadcast on each channel. These pilot data can the project information line 84 mosaic screen.

Configuration data typically includes guidance on the number of mosaic images, the size and position of each display element in each of the mosaic image, the size of the cursor frame boundaries, which can move the cursor. This information will be used in order to allow appropriate performed in the decoder application to correctly carry out the positioning and movement of the master cursor. In addition, these data identify the location of each channel in the mosaic images (page number and coordinates), the PID of the corresponding sound in the above linked thread sound data and the reference pilot data for this channel.

In order to provide the aforementioned performed in the decoder application, the ability to switch directly to the desired channel configuration data should also include relevant information about the channel (frequency, value PID) associated with the respective element. It may also include information regarding access (pay-per-view, subscription and so on), in order to allow running in the decoder application predprinimatelyu prohibited. Finally, the configuration data includes a PID value for each tile of the page and the default message for the header (if any) corresponding to this mosaic page.

Below with reference to Fig.9-11'll see an example of a mosaic structure in which at least a fragment of the video output "hammered".

Mosaic image 100 is transmitted on channel 1, so that by pressing on the remote control numeric keys "1", the decoder is tuned to this frequency channel. In alternative implementations, the remote control may be provided with a special key, used for configuration on this frequency channel.

Mosaic image 100 comprises a window 101 with a reduced screen image that displays in real time the channel showing announcements of future transmission, which should be shown on one or more other channels, and four Windows 102 with a reduced screen image, each of which is displayed in a real-time program passed by some appropriate channel. This mosaic image also contains General information line 104 and row the security button 108, the purpose of which is described below.

By activating the mosaic image 100 output audio signal associated with the channel displayed in the window 101, and as shown in Fig.9, the common data line 104 tells the user how to navigate through the mosaic image 100. In response to pressing one of the navigation keys of the remote control are performed in the decoder application forms the floating cursor frame on one of the Windows 102, as shown by item 110 in Fig. 10, or on one of the buttons 108. This cursor can be moved in horizontal and vertical directions using the navigation keys of the remote control.

Button 108 provide quick access to one of the channels identified by the text shown on each button. For example, positioning the cursor on the button 108 with the words "CANAL SATELLITE", and press "OK" to initiate the setting of the decoder on the frequency and CANAL SATELLITE.

When the cursor 110 is located on one of the Windows 102, in the General information line 104 displays the program name, the currently displayed channel to be displayed in this window. In addition, the decoder selects and reproduces the stream audiance decoder per channel, displayed in this window.

As described above with reference to Fig.4-7, in some cases, the decoder may not have full access to all channels. For example, some channels may be allocated for a PPV program or may require additional subscription by the user. In this case, it seems undesirable that the user had full access to the sound and image of a program displayed in the display Windows 102. The limitation of the output signal into a mosaic structure 100 is particularly desirable because the window 102 has a size large enough for the user to be able to view the program to which he may not have full access rights.

Accordingly, in one embodiment, the implementation decodeme an application that manages a mosaic image made with the possibility of controlling the time during which the cursor frame 110 is in the same position. After a certain period of time, such as 30, the application will compare the access rights for the given channel with the access rights of the decoder to check whether the user has the right to full access to the program or channel, so what gives on the audio output signal, associated with the channel displayed in the window 101, and accordingly moves the cursor (in this implementation in that case, if the output sound signal corresponds to the channel displayed in the window 101, the cursor is not formed; this point is not essential). Almost simultaneously, the output signal for the channel displayed in the window 102 mosaic patterns, is turned off, as shown by the position 112 in Fig.11, thus preventing the viewing of this program by the user. In this case, the application may prompt the user to pay for access to this channel, as shown at position 104 in Fig.11.

Video output one or more Windows 102 can be "scored" by simply disabling ("cut") the output signal in the part of the screen where this window. At the same time "driving" can be implemented in any of several different ways, as described below.

As mentioned earlier, the decoder typically has a four-layer structure of the image displayed on the TV screen; these four layers are a layer of still images, the layer of moving images, the graphic layer and the layer of the cursor. The graphics layer is preferably used, the application can control the display of text, images or combined text and images in a layer of still images, overlapping at least a fragment of the mosaic window 102 and thereby closing the video displayed in this window.

This text and/or graphic image may have any suitable shape. For example, the application can control the formation of:

(i) square, rectangle, or other geometric shapes for at least a partial overlap mentioned Windows;

(ii) channel logo displayed in this window.

(iii) text advertising a program, or currently in, or planning to show on this channel; and/or

(iv) a still image associated with a certain program, or currently in, or planning to show on this channel.

These parts of the image can be pre-stored in the memory of the decoder to extract and use as needed. For example, such text and/or image can be loaded by the decoder together with the audiovisual information for the mosaic structure 100.

The introduction of an additional layer of moving image window 102 mosaic patterns may be additionally or alternatively "Zam together with audio-visual information for the mosaic structure 100.

The decoder can be programmed so that each time you initialize the decoder will display the channel with a mosaic image. In addition, although the cursor can also be set to the same channel each time activating mosaic patterns, and other possible options for implementation. For example, by activating the decoder may receive the mosaic image with the cursor, the illumination channel that the user was looking last. When switching between screens with mosaic images of one channel can be seen on all screens. For example, in Fig.5 and 6 shows the channel 9. Similarly, when the user switches to a channel with a mosaic image, a screen may appear with a mosaic image in which the said channel selected, ensuring the effect of the type "zoom" - the transition from display in full screen mode to the reduced version in one of the Windows of the mosaic image.

In the above-described embodiments of the present invention pressing "OK" in the situation when the cursor is placed on a window mosaic image, causes the setting of the decoder on a frequency channel that is displayed in a window moat one of several different applications, stored in the decoder. For example, pressing one of the keys In-E (key And is usually reserved for the volume level, as shown in Fig.4) can trigger decoder electronic program guide (Epps) associated with the channel displayed in the window that contains the cursor.

There are many different types of Epps. For example, the EPP may include displayed in text form schedule for the transfer of future programmes on the channel. Displaying information of this type is well known in the art and will not be described here in detail. In alternative implementations, as shown in Fig.12, the EPP may contain mosaic image 120, which includes a set of mosaic Windows 122 (although in Fig.12 shows only three Windows, there can be any other number of Windows or the configuration of the Windows). Each window contains an image (still or moving) of the future programme, together with the name (124) of this program. Mosaic image also includes General information line 126 indicating the name of the channel and the time period covered by the mosaic image 120.

Performed in the decoder application forms the floating cursor frame is UYa navigation keys of the remote control. Positioning the cursor on a window displays the names and information about the duration of the program, as shown by the position 128 in Fig.12, together with brief information about the content of the program, as shown by the position 130 of Fig.12.

To display the programs that will be shown in a later period of time, you may need to address other mosaic images Epps this channel. For example, when the cursor is placed on the window 122 in the right part of the mosaic image, the choice pointing to the right navigation arrow will cause the next mosaic image with three programs that should be shown in a later period of time, and displayed. Similarly, if the cursor is placed in the left part of the mosaic image 122, the choice towards the left navigation arrow will cause a transition to another mosaic image with three programs that have already shown or to be shown during the earlier (previous) period of time, and displaying it.

Epps may be due to the configuration of the decoder on the frequency channel containing the mosaic structure 120. In alternative implementations, the APP may be adopted by the decoder together with the BCC is .12, or instead, the EPP may be in the form of a mosaic structure 80 shown in Fig.4, to display information about the programs that will be shown on all channels at a certain time. In this example, each window 81 displays a still or moving image of a program, which should be shown at a certain time on a given channel, for example one hour. This time is preferably indicated in the information line 84. The cursor will move to the mosaic structure causes the display name of the selected program in the information line 84. Pressing special keys of the remote control initiates the display of the electronic program guide with a similar mosaic image for different values of time, for example two hours.

In addition to the call Epps or alternatively, pressing one of the keys In may initiate the display decoder for more information about the program, shown in the window where the cursor is located. This information preferably includes the program name, start time, end time and/or duration, and information on the content of the program. This patterns. In alternative implementations, it can be loaded by the decoder as necessary in its display.

In embodiments of the mosaic structure described with reference to Fig.4-11, the cursor keeps a constant size and format (color, shape etc) when moving on the mosaic image. In an alternative implementation, the format of the cursor may be different depending on some characteristics of the window that contains the cursor. In one implementation options of the application can change the color of the cursor depending on the access rights assigned to the program and/or channel displayed in the window where the cursor is located. For example, the cursor may be green, if the user has full access rights to the program and the channel displayed in the window where the cursor is located, and red if the user does not have full access to the program and the channel displayed in the window that contains the cursor.

Mentioned the cursor may also vary depending on other characteristics, not only access rights. For example, the user can define some specific channel as a "favorite" channel, for example, by pressing spezialmaschinen this channel as a "favorite" channel is memorized in the memory of the decoder, so when the cursor is subsequently positioned on the window displaying the channel, the cursor is displayed in a different color, for example blue. As an alternative to choose a "favorite" channel through mosaic structure, some application stored in the decoder may display a list of all accepted by the decoder channels, the user selects different channels from this list as a "favorite" channels using the remote control.

In addition to this selection cursor "favorite" channels, the format of the cursor may be different depending on the nature of the program displayed in the window, on which the cursor is positioned. For example, the cursor may change the format depending on the program categories (e.g., "children's program", "adults-only"), thematic focus of the program (for example, "sports", "wildlife", "politics"), and so on,

In another configuration, additionally, the user may be determined by "clogging" of the image and/or sound for some specific Windows of a mosaic structure. For example, the user may want to restrict any access to the channels that usually show programs for adults, if such destuser is located on the window, showing some program and/or the channel to which the user wishes to restrict access, the user can give the command decoder to prevent any access to this channel. This information is stored in the decoder, so that subsequent activation of this mosaic structure of the video and audio information for this channel "hammered". For security reasons, the decoder may prompt the user to enter a PIN code before you can change access rights.

In the above with reference to Fig.4-11 embodiments of the channels displayed in a certain structure (education), defined by the provider of audiovisual data of these channels. Accordingly, various "favorite" channels the user can be distributed in a mosaic structure in random order. In order to make it possible to change the position of the various Windows in this structure, in one embodiment, the implementation decodeme application is arranged to control the relative position of the Windows in the mosaic structure.

As mentioned above, the decoder receives from broadcast configuration data, which include guidance on the number of tiles and the size and position to cameramate received data about the location so to the location of the display elements on the screen meets the requirements of the user.

In one embodiment, the implementation of these decodeme application is arranged to control the relative position of the Windows of a mosaic image based on the received access rights for channels or programs that are displayed in these Windows. For example, programs and channels with pay-per-view, for which the user does not have full access rights, can be shown in adjacent Windows of a mosaic structure.

In addition or as an alternative mentioned decodeme the application can be configured to control the relative position of the Windows of a mosaic image, based on commands from the remote control. That way the user can easily change the relative position of the Windows in the mosaic structure, for example, by pressing one of the keys In-S remote control. For example, open mosaic image can be pressing some keys have been grouped by themes, such as sports, wildlife, children's programs, adult programs, etc.,

Fig.4-12 illustrated versions of mosaic structures in the Windows which is not limited to television programs. For example, the mosaic structure 80 shown in Fig.4, may include one or more Windows associated with the respective radio channels. In this case, the window mosaic patterns for these channels display the logo of the station.

The above-mentioned decoder can also receive frequency channels with other mosaic structures. As an example in Fig.13 shows a mosaic structure 140 from the Windows 142, each of which displayed the logo of the radio channel and the channel name shown in this window 142. This mosaic image also contains General information line 146. Performed in the decoder application forms the floating cursor frame, shows the position 148. This cursor can be moved in horizontal or vertical directions using the navigation keys of the remote control. For example, in Fig.5 the cursor 83 is positioned so that the selected first from the bottom and the third side window. The indication on what music is playing now on the channel displayed in this window is displayed in the information line 146. The decoder also chooses the audio data stream associated with this channel, and reproduces it.

Pressing "Ormala, on the selected channel. For example, as shown in Fig.14, pressing "OK" on the remote control initiates the generation of the image decoder with additional information on the transfer transmitted at this time on this channel. Alternatively, pressing the "OK" button initiates the display of the text decoder schedule of future transmission of musical works on this channel or additional information about the musical piece that is being broadcast at the moment.

In Fig.15 shows a mosaic structure 160 includes box 162, each of which is associated with the corresponding interactive application stored in memory of the decoder. Each window contains the logo of the application and indicating the name of the application (item 164). Performed in the decoder application forms the floating cursor frame, shows the position 166. This cursor can be moved in horizontal and vertical directions, using the navigation keys of the remote control. For example, in Fig.15 the pointer 83 is positioned so that the selected first bottom and the second side of the window. Pressing "+" on the remote control causes the start interactivee; margin-top:2mm;">Claims
