As used herein, terms used in the present invention are selected from general terms that are widely used in the present invention while taking into account the functions of the present invention, but these may vary depending on the intention or custom of a person skilled in the art or the emergence of new technologies. In addition, in certain cases, there may be a term arbitrarily selected by the applicant, in which case the meaning thereof will be described in the description of the corresponding invention. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

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

1, an overall broadcasting system including an image display apparatus according to an exemplary embodiment of the present invention includes a content provider (CP) 10, a service provider (SP) 20, A network provider (NP) 30 and an HNED 40. [ The HNED 40 corresponds to, for example, a client 100 which is an image 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. 1, a terrestrial broadcaster, a cable SO (System Operator), a MSO (Multiple System Operator), a satellite broadcaster, Internet broadcaster and the like can be exemplified.

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

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

Meanwhile, the service provider 20 can 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 a unicast method, when a receiver requests data from a server, the server can transmit data to the receiver upon request. The multicast method is a method of transmitting data to a plurality of receivers of a specific group. For example, the server can transmit data to a plurality of pre-registered receivers at once. An Internet Group Management Protocol (IGMP) protocol may be used for multicast registration.

As an example of such restriction reception or content protection, a scheme such as a cable card (CableCARD) and a DCAS (Downloadable Conditional Access System) may be used.

On the other hand, the client 100 can also provide the content through the network. In this case, conversely, conversely, conversely, the client 100 may be a content provider, and the content provider 10 may receive content from the client 100. [ In this case, there is an advantage that an interactive content service or a data service is possible.

2 is a diagram schematically showing another example of an entire broadcasting system including an image 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, a smart TV, an HBBTV, or the like.

The video display device 100 may include a broadcast interface 101, a section filter 102, an AIT filter 103, an application data processing section 104, a broadcast data processing section 111, a media player 106 ), An Internet protocol processing unit 107, an Internet interface 108, and a runtime module 109.

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

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

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

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

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

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

The service provider performs a service provider discovery operation (S301). The video display device transmits an SP connection request (Service Provider Attachment Request) signal (S302). When the SP connection is completed, the video display device receives the provisioning information (S303). Further, 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).

More specifically, the following will be described.

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 methods for finding an address list that can receive information (for example, SP discovery information) about an SD (service discovery) server, for example, as follows. First, an address preset in the video display device or an address set by the user's manual operation can be used. Second, you can use the DHCP-based SP discovery method. Third, DNS SRV-based SP discovery method can be used. Also, the video display device accesses a server of an address obtained by any one of the above three methods, and receives a service provider discovery record containing information necessary for service discovery by SP. Then, the service searching step is carried out using this. These processes are available in either push mode or pull mode.

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

Further, a separate authentication procedure may be performed by accessing the authentication service server of the SP designated as the SP authentication locator, and then the service authentication procedure may be performed.

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

In the service attaching process, the video display device provides its own ID and location information to the data transmitted to the server, and the service attachment server can specify the service to which the video display device subscribes based on the ID and the location information. Further, the address information for obtaining the service information to be received by the video display device is provided in the form of a provisioning information table. The address information corresponds to the connection information of the master SI table. When such a method is used, it is easy to provide customized services for each subscriber.

The service information includes a master SI table record for managing connection information and version for a virtual channel map, a virtual channel map table for providing a service list of a package type, and a virtual channel description table , And a source table containing access information to access the actual service.

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

Figure 4 is a more detailed illustration of Figure 3. Hereinafter, the relationship of the data in the SI will be described with reference to FIG.

The master SI table contains location information for 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. When any one of all tables connected in the arrow direction 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 increase of the corresponding table. Therefore, by monitoring the master SI table, it is possible to immediately check the change in the entire SI table.

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

There may be one Master SI table per service provider. However, when the configuration of the service is different according to the region or the subscriber (or subscriber group), the service provider designes a plurality of master SI tables to provide a customized service for each unit. In such a 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 may include location information for acquiring the detailed information, rather than including detailed channel information in the virtual channel map. The virtual channel description location of the virtual channel map table indicates the location of the virtual channel description table including the 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 (for example, IP address, port, AV codec, transmission protocol, etc.) necessary for accessing the actual service on a service-by-service basis.

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 the push mode and the pull mode are available. On the other hand, the master SI table can be transmitted in multicast for version management, and receives the multicast stream to monitor the version change.

FIG. 5 is a diagram showing an example of the image display apparatus shown in FIG. 1 or FIG. 2 in more detail. However, the drawings shown in FIG. 5 are merely examples, and the scope of rights of the present invention should in principle be determined by claims rather than FIG.

The service manager 713 controls the manager associated with the service, such as the service delivery manager 703, the service discovery manager 710, the service control manager 709, and the 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. The service manager 713 receives the service information of the channel from the PSI & PSIP and / or SI Decoder 704 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 705.

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

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

The metadata manager 712 manages the 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 provider provided by the service discovery manager 710 Store the necessary information. Also, the SI & Metadata DB 711 can store setup data and the like for the system.
