The program searching module links to each other with the keyword extraction module, is used for search key search network information source according to keyword extraction module transmission, program or the channels of network TV of search and search key coupling from network.
For instance, if the program of the current broadcast of television set is four " exploration discovery " programs of central authorities, the user wishes program source identical in the search network, can start the internet program function of search by TV remote controller or control panel.After the internet program function of search of television set starts, TV MCU will be controlled demultiplexing and decoder module analyzing atransmission stream, therefrom obtain SI, then by the parsing of SI being obtained the short_event_descriptor in the EIT table, obtain the event_name(event name among the short_event_descriptor), the programm name that obtains the television set current playing program is " exploration discovery "; By the parsing of SI being obtained the service_descriptor in the SDT table, obtain the service_name among the service_descriptor, the channel designation that obtains the television set current playing program is " four in central authorities ".
Demultiplexing and decoder module are transferred to the keyword extraction module with programm name " exploration discovery " and the channel designation " four in central authorities " that obtains, the keyword extraction module is therefrom extracted search key " exploration discovery " and " four in central authorities ", the search key " exploration discovery " and " four in the central authorities " that extract are transferred to the menu generation module, the menu generation module generates " search key list menu " as shown in Figure 2, and the menu that generates is transferred to the display module demonstration.
This moment, the user can choose the keyword that needs search from " the search key list menu " that show, select " exploration discovery " as the user, MCU will control the keyword extraction module search key " exploration discovery " will be transferred to the program searching module, control mixed-media network modules mixed-media simultaneously and connect network, the program searching module is searched the program source with " exploration discovery " coupling with the media resource in the search network.Then Search Results is transferred to the menu generation module, menu generation module Search Results generates " search result list menu ", " search result list menu " is transferred to display module shows.
The user therefrom chooses the internet program that needs switching according to " the search result list menu " that show, confirms that back MCU will control television set and switch to the network information source from television information source, the program in the playing network.If do not search respective program, still keep the normal play of current Digital Television, only need to eject a wicket prompting user and do not search identical internet program.
Embodiment of the invention flow chart specifically comprises the steps: as shown in Figure 3
1, television set receives television information source, plays TV programme;
2, the user starts television set internet program function of search, and television set is resolved SI, obtains programm name and the channel designation of current playing program;
3, generate " search key list menu " for user's selection according to programm name and channel designation;
4, television set connects network, the internet program of the search key of choosing with the user in search network coupling;
5, Search Results is shown to the user by " search result list menu ";
6, the user chooses the internet program that needs broadcast from " search result list menu ";
7, television set switches to the network information source from television information source, plays the internet program that the user chooses.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
