 1 is a diagram 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 FIG. 1, an entire broadcasting system including a video display device according to an embodiment of the present invention includes a content provider (CP) 10, a service provider (SP) 20, It may be divided into a network provider (NP) 30 and an HNED 40. The HNED 40 corresponds to, for example, the client 100 which is a video display device according to an embodiment of the present invention. The client 100 corresponds to an image display device according to an embodiment of the present invention, and the image display device is, for example, a network TV, a smart TV, an IPTV, or the like.

The content provider 10 produces and provides various contents. As shown in FIG. 1, the content provider 10 includes a terrestrial broadcaster, a cable system operator or a multiple system operator, a satellite broadcaster, and an internet broadcaster. An internet broadcaster and the like can be exemplified.

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

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

Meanwhile, the service provider 20 may provide a service to the client 100 using a unicast or multicast scheme. The unicast method is a method of transmitting data 1: 1 between one sender and one receiver. For example, in the unicast method, when a receiver requests data from a server, the server may transmit data to the receiver according to the request.

Further, the runtime module 109 includes, for example, an application manager and a browser as shown in FIG. 2. The application manager, for example, uses AIT data to control the life cycle for the interactive application. The browser, for example, performs a function of displaying and processing the interactive application.

FIG. 3 is a diagram illustrating a step in which the video display device illustrated in FIG. 1 or 2 receives channel information and the like by accessing a service provider. Of course, Figure 3 is an embodiment, and the scope of the present invention is not limited only by the method of Figure 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 a master SI table from the service provider (S304), receives a Virtual Chnnanel Map table (S305), receives a Virtual Channel Description table (S306), and receives a Source table ( S307).

More detailed description is as follows.

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

There are three ways to find an address list that can receive information (eg, SP discovery information) about an SD (service discovery) server. First, an address set in the image display device or an address set by a user's manual operation may be used. Second, DHCP-based SP discovery can be used. Third, the DNS SRV-based SP discovery method may be used. In addition, the video display device accesses the server of the 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. And using this, the service search step is performed. These processes are available in either push mode or pull mode.

Access the SP attachment server designated as the SP attachment locator of the SP discovery record and perform a registration procedure (or service attachment procedure).

In addition, after accessing the authentication service server of the SP designated as the SP authentication locator and performing a separate authentication procedure, the service authentication procedure may be performed.

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

In the service attachment process, the video display device includes its ID and location information in the data transmitted to the server, and the service attachment server may specify a service subscribed to by the video display device based on this. Furthermore, address information for obtaining service information that the video display device wants to receive is provided in the form of a provisioning information table. The address information corresponds to connection information of the master SI table. When using such a method, it is easy to provide a customized service for each subscriber.

The service information may include a master SI table record managing access information and a version of a virtual channel map, a virtual channel map table providing a list of services in a package form, and a virtual channel description table including detailed information of each channel. And a source table containing access information for accessing the actual service.

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

FIG. 4 is a diagram 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 for receiving 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 indicates version information of the virtual channel map. When any one of all tables connected in the direction of the arrow starting from the master SI table shown in FIG. 4 is changed, the version of all upper tables (up to the master SI table) increases with the version increase of the corresponding table. Therefore, by monitoring the master SI table, there is an advantage that can immediately see the change on the entire SI table.

For example, when a change occurs in the source table, the version of the source table increases, and the version of the virtual channel description table that references the source table also changes. 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.

There may be one Master SI table for each service provider. However, if the service configuration is different by region or by subscriber (or subscriber group), the service provider is designed to have a plurality of master SI tables to provide customized services for each unit. In this case, it is possible to efficiently provide a customized service according to 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 channels in the virtual channel map, but includes location information from which the detailed information can be obtained. The virtual channel description location of the virtual channel map table indicates a location of a virtual channel description table including channel detail information.

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

The source table provides connection information (eg, IP address, port, AV codec, transmission protocol, etc.) necessary for accessing a real service by service.

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

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. The service manager 713 receives service information of a channel from a PSSI and / or SI Decoder 704 and sets an audio / video PID (packet identifier) of the selected channel to the demultiplexer 705.

The service discovery manager 710 provides information necessary for selecting a service provider providing a service. Upon receiving a signal for channel selection from the service manager 713, the service discovery manager 710 finds a service using the information.

The service control manager 709 is in charge of selecting and controlling a service. For example, if a user selects a live broadcasting service like the conventional broadcasting method, IGMP or RTSP is used. If a user selects a service such as VOD (Video On Demand), RTSP is used to select and control the service. 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) or a session initiation protocol (SIP). The protocols are one embodiment, and other protocols may be used depending on implementation.
