1 is a view schematically showing an example of an entire broadcasting system including a video display device according to an embodiment of the present invention.

As shown in Figure 1, the entire broadcast system including the video display device according to an embodiment of the present invention, a content provider (Content Provider; CP) 10, a service provider (Service Provider; SP) 20, It can be divided into a network provider (Network Provider; NP) 30 and HNED (40). The HNED 40 corresponds to, for example, the client 100 as a video display device according to an embodiment of the present invention. The client 100 corresponds to a video display device according to an embodiment of the present invention, and the video display device is, for example, a network TV, a smart TV, or an IPTV.

The content provider 10 produces and provides various contents. As shown in FIG. 1, the content provider 10 includes terrestrial broadcasters, cable operators (SO) or multiple system operators (MSOs), satellite broadcasters, and satellite broadcasters. A ruler (Internet broadcaster) may be exemplified.

In addition, the content provider 10 may provide various applications in addition to broadcast content. In this regard, it will be described in more detail later.

The service provider 20 may provide contents packaged by the content provider 10 by service packaging. For example, the service provider 20 of FIG. 1 may package the first terrestrial broadcast, the second terrestrial broadcast, the cable MSO, the satellite broadcast, various Internet broadcasts, applications, and the like, and provide it to the user.

Meanwhile, the service provider 20 may provide a service to the client 100 using a unicast or multicast method. The unicast method is a method of transmitting data 1:1 between one sender and one receiver. For example, in the case of the unicast method, when the receiver requests data from the server, the server may transmit data to the receiver according to the request. The multicast method is a method of transmitting data to a plurality of recipients of a specific group. For example, the server may transmit data to a plurality of pre-registered receivers at once. For such multicast registration, an Internet Group Management Protocol (IGMP) protocol may be used.

The network provider 30 may provide a network network for providing the service to the client 100. The client 100 may also be provided with a service by constructing a Home Network End User (HNED).

As a means for protecting the content transmitted from the video display device system as described above, conditional access or content protection may be used. As one example for such restriction reception or content protection, a method such as a cable card or a downloadable conditional access system (DCAS) may be used.

Meanwhile, the client 100 may also provide content through a network. In this case, as described above, conversely, the client 100 may be a content provider, and the content provider 10 may receive content from the client 100. When designed in this way, there is an advantage that interactive content service or data service is possible.

2 is a diagram schematically showing another example of an entire broadcasting system including a video display device according to another embodiment of the present invention.

As shown in FIG. 2, the video display device 100 according to another embodiment of the present invention is connected to a broadcast network and an Internet network. The video display device 100 is, for example, a network TV, smart TV, HBBTV, and the like.

In addition, the video display device 100, for example, broadcast interface 101, section filter 102, AIT filter 103, application data processing unit 104, broadcast data processing unit 111, media player 106 ), an Internet protocol processing unit 107, an Internet interface 108, and a runtime module 109.

Through the broadcast interface 101, application information table (AIT) data, real-time broadcast content, application data, and stream events are received. Meanwhile, the real-time broadcast content may be referred to as Linear A/V Content.

The section filter 102 performs section filtering on the four data received through the broadcast interface 101 to transmit AIT data to the AIT filter 103, and the linear AV content is the broadcast data processing unit 111. The stream event and application data are transmitted to the application data processing unit 104.

Meanwhile, non-linear A/V content and application data are received through the Internet interface 108. The non-linear AV content may be, for example, a Content On Demand (COD) application.

The non-linear AV content is transmitted to the media player 106, and the application data is transmitted to the runtime module 109.

Furthermore, the runtime module 109 includes, for example, an application manager and a browser, as shown in FIG. 2. The application manager controls life cycle for an interactive application using, for example, AIT data. Then, the browser performs a function of displaying and processing the interactive application, for example.

FIG. 3 is a diagram illustrating a step in which the video display device shown in FIG. 1 or 2 connects to a service provider and receives channel information. Of course, FIG. 3 is an embodiment, and the scope of the present invention is not limited only by the method of FIG. 3.

The service provider performs a service provider discovery operation (S301). The video display device transmits an SP connection request signal (S302). When the SP connection is completed, the video display device receives provisioning information (S303). Furthermore, the video display device receives the master SI table from the service provider (S304), receives the Virtual Chnnanel Map table (S305), receives the Virtual Channel Description table (S306), and receives the Source table ( S307).

The details are as follows.

The service provider discovery may mean a process in which service providers providing services related to IPTV find a server providing information about their services.

There are three ways to find a list of addresses that can receive information (for example, SP discovery information) about an SD (service discovery) server. First, it is possible to use a preset address for a video display device or an address set by a user's manual operation. Second, a DHCP-based SP discovery method can be used. Third, DNS SRV-based SP discovery method can be used. In addition, the video display device accesses a server having an address obtained by any one of the above three methods, and receives a service provider discovery record containing information required for service discovery for each SP. Then, using this, a service discovery step is performed. These processes can be either push mode or pull mode.

Connect to the SP attachment server designated as the SP attachment locator of the SP discovery record, and perform the registration procedure (or service attachment procedure).

Furthermore, a separate authentication procedure may be performed by accessing an SP authentication service server designated as an SP authentication locator, and then a service authentication procedure may be performed.

Meanwhile, the data transmitted from the server to the video display device after the successful service attachment procedure may be in the form of a provisioning information table.

In the service attachment process, the video display device provides its own ID and location information in data transmitted to the server, and the Service attachment server can identify the service to which the video display device subscribes. Furthermore, the address information from which the video display device can obtain the service information to be received is provided in the form of a provisioning information table. The address information corresponds to the access information of the master SI table. When using this method, it is easy to provide customized services for each subscriber.

In addition, the Service Information includes a master SI table record that manages access information and a version for a virtual channel map, a virtual channel map table that provides a package type service list, and a virtual channel description including detailed information of each channel. It includes a table and a source table that contains access information to access the actual service.

4 is a diagram illustrating an example of data used in the steps shown in FIG. 3.

FIG. 4 is a view showing FIG. 3 in more detail. Hereinafter, the relationship between the data in the SI will be described with reference to FIG. 4.

The Master SI table includes location information that can receive each virtual channel map and version information of each virtual channel map.

Each virtual channel map is uniquely identified by a virtual channel map identifier, and the virtual channel map version represents version information of the virtual channel map. If any one table among all the tables connected in the direction of the arrow starting from the master SI table shown in FIG. 4 is changed, the version of all the upper tables (up to the master SI table) increases with the version of the corresponding table. Therefore, by monitoring the master SI table, there is an advantage that the change on the entire SI table can be immediately confirmed.

For example, when a change occurs in the source table, the version of the source table is increased, and the version of the virtual channel description table that references the source table is also changed. Therefore, the change of the lower table causes the change of the upper table, and ultimately, the version of the master SI table is changed.

One Master SI table may exist for each service provider. However, when the configuration of the service is different for each region or for each subscriber (group of subscribers), the service provider is designed to have a plurality of master SI tables in order to provide customized services for each unit. When designed in this way, it is possible to efficiently provide customized services suitable for the subscriber's region and subscription information through the master SI table.

The virtual channel map table may have one or more virtual channels, and does not include detailed information of the channel in the virtual channel map, but includes location information for obtaining the detailed information. The virtual channel description location of the virtual channel map table informs the location of the virtual channel description table including channel detailed information.

The virtual channel description table includes detailed information of the virtual channel, and access to the virtual channel desctiprion table by using the virtual channel description location of the virtual channel map table.

The source table provides access information (eg, IP address, port, AV codec, transport protocol, etc.) required for accessing the actual service for each service.

The master SI table, virtual channel map table, virtual channel description table, and source table described above are logically transmitted through four separate flows, and both push mode or pull mode are possible. Meanwhile, the master SI table may be transmitted in multicast for version management, and a version change is monitored by receiving a multicast stream.

FIG. 5 is a diagram illustrating an example of the image display device illustrated in FIG. 1 or 2 in more detail. However, the drawing shown in FIG. 5 is only one embodiment, and the scope of the present invention should be determined by the claims rather than FIG. 5 in principle.

The network interface unit 701 receives packets received from the network, and transmits the packet to the network. That is, the network interface unit 701 receives a service, content, etc. from a service provider through a network network.

The TCP/IP manager 702 is involved in packet transmission from the source to the destination for packets received by the video display device 700 and packets transmitted by the video display device 700. Then, the TCP/IP manager 702 classifies the received packets to correspond to an appropriate protocol, and classifies them into a service delivery manager 705, a service discovery manager 710, a service control manager 709, and a metadata manager 712. Prints out the packet.

The service delivery manager 703 is responsible for controlling received service data. For example, when controlling real-time streaming data, RTP/RTCP may be used. When the real-time streaming data is transmitted using RTP, the service delivery manager 703 parses the received data packet according to RTP and transmits it to the demultiplexer 705 or to control the service manager 713. Accordingly, it is stored in the SI&Metadata DB 711. Then, the network reception information is fed back to a server providing a service using RTCP.

The demultiplexer 705 demultiplexes the received packets into audio, video, and PSI (Program Specific Information) data, and transmits them to the audio/video decoders 706 and 707, and the PSI&(PSIP and/or SI) Decoder 704, respectively. do.

The PSI&(PSIP and/or SI) Decoder 704 decodes service information such as, for example, PSI (Program Specific Information).

Further, the PSI&(PSIP and/or SI) Decoder 704 decodes the received sections to create a database for service information, and the database for service information is stored in the SI&Metadata DB 711.

The audio/video decoder 706/707 decodes video data and audio data received from the demultiplexer 705. The audio data decoded by the audio decoder 706 and the video data decoded by the video decoder 707 are provided to the user through the display unit 708.

The UI manager 714 and the service manager 713 manage the overall state of the video display device 700, provide a user interface, and manage other managers.

The UI manager 714 provides a graphical user interface (GUI) for a user using an on-screen display (OSD), and receives a key input from a user to perform a receiver operation according to the input. For example, when a key input regarding channel selection is received from a user, the key input signal is transmitted to the service manager 713.

The service manager 713 controls a manager associated with a service, such as a service delivery manager 703, a service discovery manager 710, a service control manager 709, and a metadata manager 712.

In addition, the service manager 713 creates a channel map and selects a channel using the channel map according to a key input received from the user interface manager 714. In addition, the service manager 713 receives the service information of the channel from the PSI&(PSIP and/or SI) Decoder 704 and sets the audio/video PID (Packet Identifier) of the selected channel to the demultiplexer 705.

The service discovery manager 710 provides information necessary to select a service provider providing a service. When a signal regarding channel selection is received from the service manager 713, the service discovery manager 710 finds a service using the information.

The service control manager 709 is responsible for selecting and controlling services. For example, if a user selects a Live Broadcasting service such as an existing broadcasting method, IGMP or RTSP is used, and when a service such as Video On Demand (VOD) is selected, RTSP is used to select and control the service. To perform. The RTSP protocol may provide a trick mode for real-time streaming. In addition, the service control manager 709 may initialize and manage a session through the IMC gateway using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The above protocols are one embodiment, and other protocols may be used according to implementation examples.

The metadata manager 712 manages metadata associated with the service and stores the metadata in the SI&Metadata DB 711.

The SI&Metadata DN 711 selects the service information decoded by the PSI&(PSIP and/or SI) Decoder 704, the metadata managed by the metadata manager 712, and the service providers provided by the service discovery manager 710. Save necessary information. In addition, the SI&Metadata DB 711 may store setup data for the system.

The SI&Metadata DB 711 may be implemented using non-volatile memory (NonVolatile RAM: NVRAM) or flash memory.

Meanwhile, the IG 750 is a gateway that collects functions necessary for accessing an IMS-based IPTV service.
