BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

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 is a term arbitrarily selected by the applicant, and in this case, the meaning will be described in the corresponding description of the 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 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 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.

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. Multicasting is a method of transmitting data to a plurality of recipients of a specific group. For example, the server can send data to multiple pre-registered receivers at once. For such multicast registration, the Internet Group Management Protocol (IGMP) protocol may be used.

The network provider 30 may provide a network for providing a service to the client 100. The client 100 may establish a home network end user (HNED) to receive a service.

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

In this case, unlike the above, the client 100 may be a content provider, and the content provider 10 may receive content from the client 100. In the case of designing as described above, an interactive content service or a 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 image display device 100 is, for example, a network TV, a smart TV, an HBBTV, or the like.

In addition, the video display device 100 may include, for example, a broadcast interface 101, a section filter 102, an AIT filter 103, an application data processor 104, a broadcast data processor 111, and a media player 106. ), An internet protocol processor 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 ave content (Linear A / V Content).

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

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

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

Further, the runtime module 109 includes, for example, an application manager and a browser as shown in FIG. 2. The application manager controls the life cycle for the interactive application using, for example, AIT data. 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 to 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).

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

Meanwhile, data transmitted from the server to the video display device after the service attachment procedure is successful 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 virtual channel description including detailed information of each channel. tables, and source tables that contain access information to access the actual services.

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, when the service configuration is different for each region or 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 the channels in the virtual channel map, but includes location information from which the detailed information may be obtained. The virtual channel description location of the virtual channel map table informs the location of the 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 above-described master SI table, virtual channel map table, virtual channel description table, and source table 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.

FIG. 5 illustrates an example of the image display apparatus shown in FIG. 1 or 2 in more detail. 5 is only an example, and the scope of the present invention should be determined by the claims rather than the principles of FIG. 5.

The video display device 700 includes a network interface unit 701, a TCP / IP manager 702, a service delivery manager 703, and a demultiplexer (Demux). 705, PSIP and / or SI decoder 704, audio decoder 706, video decoder 707, display A / V and OSD module 708 , Service Control Manager (709), Service Discovery Manager (710), Metadata Manager (712), SI & Metadata DB (711), UI Manager (714), and Services Manager 713 and the like.

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

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

The service delivery manager 703 is responsible for controlling the received service data. For example, RTP / RTCP can be used to control real-time streaming data. When transmitting the real-time streaming data using the RTP, the service delivery manager 703 parses the received data packet according to the RTP and transmits it to the demultiplexer 705 or under the control of the service manager 713. Accordingly stored in the SI & Metadata DB (711). Then, the RTCP is used to feed back the network reception information to a server that provides a service.

The demultiplexer 705 demultiplexes the received packet into audio, video, program specific information (PSI) data, and the like, and transmits the demultiplexer 705 to the audio / video decoders 706 and 707 and the PSIP and / or SI decoder 704, respectively. do.

PSIP and / or SI Decoder 704 decodes service information such as, for example, Program Specific Information (PSI). That is, the PSIP and / or SI Decoder 704 receives and decodes the demultiplexed PSI section, the Program and Service Information Protocol (PSIP) section, or the Service Information (SI) section from the demultiplexer 705.

In addition, the PSIP and / or SI Decoder 704 decodes the received sections to create a database of service information, and stores the database of service information in the SI & Metadata DB 711.

An audio / video decoder 706/707 decodes the video data and the audio data received at 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 Graphic User Interface (GUI) for a user by using an OSD (On Screen Display) and the like, and receives a key input from the user to perform a receiver operation according to the input. For example, upon receiving a key input related to channel selection 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. 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.

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

Of course, if necessary, it is also possible to design the tuner and the demodulator without including the network module, and conversely, it is possible to design the network interface without the tuner and the demodulator.

The tuner selects an RF broadcast signal corresponding to a channel selected by a user or all pre-stored channels among RF (Radio Frequency) broadcast signals received through an antenna. Also, the selected RF broadcast signal is converted into an intermediate frequency signal, a baseband image, or a voice signal.

For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal (DIF). If the selected RF broadcast signal is an analog broadcast signal, it is converted into an analog baseband image or voice signal (CVBS / SIF). That is, the tuner can process both digital broadcast signals or analog broadcast signals. The analog baseband video or audio signal CVBS / SIF output from the tuner may be directly input to the controller 170.

In addition, the tuner may receive a single carrier RF broadcast signal according to the Advanced Television System Committee (ATSC) scheme or a multi-carrier RF broadcast signal according to the Digital Video Broadcasting (DVB) scheme.

The tuner may sequentially select RF broadcast signals of all broadcast channels stored through a channel memory function among RF broadcast signals received through an antenna and convert the RF broadcast signals into intermediate frequency signals or baseband video or audio signals.

The demodulator receives a digital IF signal DIF converted by the tuner and performs a demodulation operation.

For example, when the digital IF signal output from the tuner is an ATSC scheme, the demodulator performs 8-VSB (8-Vestigal Side Band) demodulation, for example. In addition, the demodulator may perform channel decoding. To this end, the demodulator includes a trellis decoder, a de-interleaver, and a reed solomon decoder to perform trellis decoding, deinterleaving, and reed soloman decoding. Can be done.

The demodulator may also perform channel decoding. To this end, the demodulator may include a convolution decoder, a deinterleaver, a reed-soloman decoder, and the like to perform convolutional decoding, deinterleaving, and reed soloman decoding.

The demodulator may output a stream signal TS after performing demodulation and channel decoding. In this case, the stream signal may be a signal multiplexed with a video signal, an audio signal, or a data signal. For example, the stream signal may be an MPEG-2 TS (Transport Stream) multiplexed with an MPEG-2 standard video signal, a Dolby AC-3 standard audio signal, or the like. Specifically, the MPEG-2 TS may include a header of 4 bytes and a payload of 184 bytes.

On the other hand, the demodulation unit described above can be provided separately according to the ATSC system and the DVB system. That is, it can be provided as an ATSC demodulation unit and a DVB demodulation unit.

The stream signal output from the demodulator may be input to the controller 170. After performing demultiplexing, image / audio signal processing, and the like, the controller 170 outputs an image to the image processor 180 and outputs an audio to the audio output unit 185.
