In order to achieve the above object, the EPG information of major region of the present invention master headed comprises complete, all service of all each department sub-headends comprise that complete NIT, SDT, many BAT tables, EIT, PAT, PMT information can sort use for each department.The present invention includes following steps:
(1) built-in specific Bouquet ID is as the specific identifier of a collection of set-top box in set-top box, and the set-top box in an area is only used a specific Bouquet ID;
(2) utilize self-defining bouquet ID list descriptor to be inserted among the NIT, describe all regions in the major region;
(3) utilize many BAT tables, every corresponding Bouquet ID of BAT table, and in table, list all business of supporting in this area;
Built-in Bouquet ID when (4) utilizing set-top box to dispatch from the factory searches the BAT table of getting its ID unanimity, and represents the business in this table.
On the frequency of major region, utilize multiplexer that the BAT table that the higher level transmits is filtered, only filter out the BAT table relevant and broadcast with this area.
Set-top box is transregional can not to circulate, and need increase a multiplexer on the frequency in district, and the BAT table that the higher level is transmitted filters, and only filters out the BAT table relevant with this area and broadcasts.Like this, the set-top box of this area, because its built-in Bouquet ID is consistent with the BAT table of broadcasting, set-top box can search the rendition list, can normally watch.And the set-top box of other regions is searched for less than the rendition list because its built-in bouquet ID is inconsistent with the BAT in the broadcasting stream, therefore can't watch.Therefore can realize the function that trans-regional set-top box can't circulate.
The present invention utilizes BAT, self-defined bouquet ID list descriptor and the built-in bouquet ID of set-top box, can realize not circulating mutually of how regional set-top box, when being watched, the user can only see this city or certain major region front end and the local channel list of managing program by oneself, but both resources advantage in the active set, do not undertake redundant construction, can give full play to the enthusiasm in each district, town again.Can be widely used in the digital video broadcasting of each major region.
