Technical Field
[0001] This invention relates to the field of set-top box technology, and in particular to a region-based set-top box channel filtering method, system, device and medium. Background Technology
[0002] With the development of digital television, set-top boxes have become widespread and developed in various regions, and each region also has its own local digital television broadcast channels, resulting in a large number of channels. In order to facilitate channel management, it is necessary to filter channels by region, with each region only managing the channels within its own region.
[0003] Currently, set-top box channel search is mainly based on the nit table (Network Information Table) and sdt table (Service Description Table), and then the bat table (Service Group Association Table) is used to filter unwanted channels. The lack of a front-end that can flexibly control the set-top box to filter channels by region makes it difficult for operators to manage regional channels.
[0004] Therefore, how to provide a region-based set-top box channel filtering method, system, device, and medium to achieve channel filtering by region, thereby improving the convenience and flexibility of channel management, has become an urgent technical problem to be solved.

[0013] Further, step S20 specifically includes:
[0014] Create a channel filter list, and iteratively compare the local area code with the channel area codes in the area filter information. Add the channels corresponding to the channel area codes that do not match the local area code to the channel filter list.

[0017] Secondly, the present invention provides a region-based set-top box channel filtering system, comprising the following modules:
[0018] The area information acquisition module is used to acquire the set-top box's local area code and area filtering information;
[0019] The channel filter list creation module is used to create a channel filter list based on the local area code and area filter information.
[0020] The channel filtering module is used by the set-top box to search for channels and filter the searched channels based on the channel filtering list.
[0021] Furthermore, the area information acquisition module is specifically used for:
[0022] When the set-top box is powered on, the local area code is obtained through the CA interface;
[0023] When the set-top box performs a channel search, it locks onto a preset main frequency point, then obtains the service group association table under the main frequency point, and parses the service group association table to obtain regional filtering information including channel area codes.

Ultimately, this enables channel filtering by region, greatly improving the convenience and flexibility of channel management.
[0032] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0037] Figure 4 This is a schematic diagram of the structure of a region-based set-top box channel filtering medium according to the present invention. Detailed Implementation
[0038] This application provides a region-based set-top box channel filtering method, system, device, and medium to achieve channel filtering by region, thereby improving the convenience and flexibility of channel management.
[0039] The technical solution in this application embodiment has the following general idea: channel filtering is performed through regional codes, which allows the front end to better allocate channels and makes it easier for the set-top box to distinguish regional channels, thereby improving the convenience and flexibility of channel management.
[0040] Example 1
[0041] This embodiment provides a region-based set-top box channel filtering method, such as... Figure 1 As shown, it includes the following steps:
[0042] Step S10: Obtain the local area code and area filtering information of the set-top box;
[0043] Step S20: Create a channel filtering list based on the local area code and area filtering information;
[0044] Step S30: The set-top box searches for channels and filters the searched channels based on the channel filter list.
[0045] Step S10 specifically involves:
[0046] When the set-top box is powered on, the local area code (zoneid) is obtained through the interface function of the CA (ConditionalAccess) interface;
[0047] When the set-top box performs a channel search, it locks the preset main frequency point, and then obtains the service group association table (bat table) under the main frequency point. It parses 0x3, 0x4a, 0xfe, and 0x6e of the service group association table to obtain regional filtering information including channel area codes.
[0048] The specific area filtering information includes: 1. CA replacement service channel information; 2. Channel TSDID, ServiceID, and NetID with area control; 3. Channel area code described for each channel; 4. LCN (International Chinese Network Inc. / TV Network) corresponding to the area.
[0049] Step S20 specifically involves:
[0050] Create a channel filter list, and iteratively compare the local area code with the channel area codes in the area filter information. Add the channels corresponding to the channel area codes that do not match the local area code to the channel filter list.
[0051] If the local area code is not among the channel area codes described in the channel description, it means that the channel corresponding to the channel area code does not belong to the local area and needs to be filtered, so it is added to the channel filtering list. Channel descriptions in the BAT table are separated by bouquetid. One area code can only filter one channel per bouquet, and each bouquet contains a CA replacement service channel and an LCN. If all channels in a bouquet are filtered, the CA replacement service channel is not filtered, and the LCN described in that bouquet must be modified to match the LCN described in that bouquet.
[0052] Step S30 specifically involves:
[0053] The set-top box searches all channels, obtains channel information for all channels through the nit table and sdt table, filters the searched channels based on the channel filtering list, and stores the channel information of the filtered channels in the database and flash memory.
[0054] Filter the channel by comparing serviceid, tsid, and netid. If they are all the same, filter the channel.
[0055] Example 2
[0056] This embodiment provides a region-based set-top box channel filtering system, such as... Figure 2 As shown, it includes the following modules:
[0057] The area information acquisition module is used to acquire the set-top box's local area code and area filtering information;
[0058] The channel filter list creation module is used to create a channel filter list based on the local area code and area filter information.
[0059] The channel filtering module is used by the set-top box to search for channels and filter the searched channels based on the channel filtering list.
[0060] The area information acquisition module is specifically used for:
[0061] When the set-top box is powered on, the local area code (zoneid) is obtained through the interface function of the CA (ConditionalAccess) interface;
[0062] When the set-top box performs a channel search, it locks the preset main frequency point, and then obtains the service group association table (bat table) under the main frequency point. It parses 0x3, 0x4a, 0xfe, and 0x6e of the service group association table to obtain regional filtering information including channel area codes.
[0063] The specific area filtering information includes: 1. CA replacement service channel information; 2. Channel TSDID, ServiceID, and NetID with area control; 3. Channel area code described for each channel; 4. LCN (International Chinese Network Inc. / TV Network) corresponding to the area.
[0064] The channel filter list creation module is specifically used for:
[0065] Create a channel filter list, and iteratively compare the local area code with the channel area codes in the area filter information. Add the channels corresponding to the channel area codes that do not match the local area code to the channel filter list.
[0066] If the local area code is not among the channel area codes described in the channel description, it means that the channel corresponding to the channel area code does not belong to the local area and needs to be filtered, so it is added to the channel filtering list. Channel descriptions in the BAT table are separated by bouquetid. One area code can only filter one channel per bouquet, and each bouquet contains a CA replacement service channel and an LCN. If all channels in a bouquet are filtered, the CA replacement service channel is not filtered, and the LCN described in that bouquet must be modified to match the LCN described in that bouquet.
[0067] The channel filtering module is specifically used for:
[0068] The set-top box searches all channels, obtains channel information for all channels through the nit table and sdt table, filters the searched channels based on the channel filtering list, and stores the channel information of the filtered channels in the database and flash memory.
[0069] Filter the channel by comparing serviceid, tsid, and netid. If they are all the same, filter the channel.
