Description

CHANNEL LIST CONSTRUCTION METHOD FOR INTEGRATION PROGRAMS OF RESPECTIVE CHANNELS}

The present invention relates to a method of constructing a channel list of a digital broadcast receiver, and more particularly to a method of constructing a channel list of a digital terrestrial broadcasting system (hereinafter referred to as "DTTV") capable of receiving multiple networks. Digital video broadcasting (DVB) refers to a digital broadcasting standard jointly developed by European countries, and digital television receives a TV broadcasting signal transmitted digitally. Digital broadcasting (DVB) provides a variety of services by the transmission of additional data. In digital broadcasting, various service information (SI) is added to program specific information (PSI) so that it can be used for the purpose of an electric program guide (EPG). As one of the data services in digital multi-channel broadcasting, EPG, which provides a program schedule and information on the contents of each program, is considered as one of the basic services. In general, channel numbers, channel names, program names, schedules, and the like, which are transmitted as data, are displayed on TV screens as program tables having a time axis and a channel axis by EPG software of a digital broadcast receiver set. Satellite-based digital broadcasting (DVB-S) system constructs a channel list using integrated PSI / SI and shows it through EPG. Parsing PSI / SI using one transponder included in the current network. Fig. 1 is a screen state diagram for explaining a conventional channel list construction method. Conventionally, a channel list using PSI / SI integrated in a specific network is constructed and shown through an electronic program guide (EPG). In the case of DVB-S, the PSI / SI is combined to form a channel list including a station name and a program number. This channel list analyzes the service description table (SDT) in the current network and shows program names by one-to-one mapping to enable playback of audio / video data and channel selection according to user channel selection. do.

However, in case of digital terrestrial broadcasting (DVB-T), it is composed of several single networks or service insertion points (SIPs), and at the same time, the basis of a multi frequency network (MFN). Is implemented. Therefore, it is impossible to implement a channel list that can know the entire network that can be received only by analyzing PSI / SI through a specific SIP.

Accordingly, an object of the present invention is a channel in which a service insertion point (SIP) is integrated based on a link-list method that can access another network through an auto channel search (ACS) function. It is to provide a channel list construction method for organizing a list and selecting a desired network directly on the EPG screen.

1 is a screen state diagram for explaining a conventional channel list implementation method;

2 is a view for explaining a channel list construction method according to an embodiment of the present invention;

3 is a view showing a channel list to enable integrated network access according to the present invention,

4 is a screen state diagram in which service contents added when the network B is selected in FIG. 3 are included in a channel list.

Features of the present invention for achieving the above object is (1) constructing a channel list for all channels in the network to which the user selected program belongs, (2) in addition to the network currently selected in the last configuration position of the channel list, Displaying other network information that is receivable using a link-list method accessible to other networks, and (3) determining whether the user has selected a network movement, and if not selecting the network movement, the channel list is cyclically If a program is selected while searching for and network movement is selected, the method moves to the selected network and (4) adding program information obtained by parsing PSI / SI from the moved network to the channel list.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a view for explaining a channel list configuration method according to an embodiment of the present invention.

The program is tuned to the program stored in the memory before powering off (step 210). In step 220, a channel list is configured for all channels broadcast in the network to which the program belongs. When ACS is performed in the cold boot mode after powering on the DTTV set for the first time, network information that can be received in the current DTTV set is registered as the last component of the channel list (step 230). It is determined whether the user has selected network movement (step 240). If the user has not selected network movement, the channel is selected while recursively searching the existing channel list (step 250). If the user has selected network movement, the program is added to the PSI / SI decoding and existing channel list from the moved network (step 260). The user then selects the channel through the channel list as shown in FIG. 3 (step 270).

3 is a view showing a channel list configured to enable integrated network access according to the present invention. As shown in FIG. 3, the channel list is configured based on a specific service of a network to which the service viewed before power-off belongs, or a network automatically selected after ACS execution. Referring to FIG. 3, the display mode corresponding to the PRESENT / FOLLOWING method is a vertical axis of transmitted transmitted / following information, and the current program title and the next program title are divided into two areas. This mode is to display on the screen as a graphic chart.

As shown in FIG. 3, the present invention shows not only the previously displayed channel name, the current program title, and the next program title, but also the reception of NETWORK and service selection. It also shows the name of the currently selected network.

4 is a screen state diagram in which the added service content is included in the channel list when the network B is selected in FIG. NNN24 and MMM25 were added by the user selecting network B, and the broadcast time of the previous network events is deleted by time zone. When comparing the channel list shown in FIG. 3 and FIG. 4, the EVENT 5 having the channel name 'CCC13' of FIG. 3 has elapsed since the airing time has elapsed and thus is not displayed on the screen. In addition, the deleted EVENT 5 was filled with the next service program EVENT 6. And the seat of EVENT 6 becomes 'No Event' indication that there is no service program.

As described above, the present invention provides a cyclic response to a remote controller input using a link-list method in which the existing channel list is accessible to another network as a result of parsing the SDT in the method of receiving digital broadcasting. By implementing the channel list, it is effective to show the user the channel list integrating the entire network.
