Problems solved by technology

[0002] At present, due to the chaotic frequency point planning of wireless terrestrial digital set-top boxes, there are many non-self wireless frequency points under one operator, such as some county-level signals or provincial-level signals under a city-level network
In this way, when users watch, they may search for many programs issued by non-local operators or programs that cannot be watched normally. The operation is cumbersome and not conducive to user expansion.

specific Embodiment

[0014] A kind of non-local program shielding method based on the wireless set-top box, by utilizing the description of the SDT table (service description table) in the MEPG2 standard, expand the function of the provider name (operator name) under this table, comprise the following steps:

[0015] a). Through the multiplexer at the front end of the operator, change or add the unique identification information of the provider name in the SDT table, such as describing a radio and television as "XXTV";

[0016] b). The set-top box starts the search, and parses the SDT table to obtain the provider name;

[0017] c). Compare whether the parsed provider name is the identifier of the operator to determine whether the operator name is correct;

[0018] d). According to the result of step c, if it is correct, the program is saved, otherwise it is not saved.

[0019] When the set-top box searches, it first judges the input frequency. If the judged frequency is an integer multiple of 100...

Abstract

The invention discloses a method for shielding non-local programs based on a wireless set-top box. By using the description under the SDT table in the MEPG2 standard and expanding the provider name function under the table, the purpose of shielding non-local programs is achieved. The method includes the following steps: a). Through the multiplexer at the front end of the operator, change or add the unique identification information of the provider name in the SDT table; b). The set-top box starts the search and parses the SDT table to obtain the provider name; c). Compare the parsed ones Whether the provider name is the identifier of the operator is to determine whether the operator name is correct; d). According to the result of step c, if it is correct, the program is saved, otherwise it is not saved. The invention not only facilitates operator management and customer expansion, but also facilitates later maintenance and operation, does not occupy bandwidth, does not increase costs, and is convenient and feasible.

Description

technical field [0001] The invention belongs to the technical field of wireless digital TV set-top boxes, and in particular relates to a non-local program shielding method based on a wireless set-top box. Background technique [0002] At present, due to the chaotic frequency point planning of wireless terrestrial digital set-top boxes, there are many non-self wireless frequency points under one operator, such as some county-level signals or provincial-level signals under a city-level network. In this way, when users watch, they may search for many programs issued by non-local operators or programs that cannot be watched normally, which is cumbersome to operate and is not conducive to user expansion. Contents of the invention [0003] The object of the present invention is to solve the above technical problems, and achieve the purpose of shielding non-local programs through a non-local program shielding method based on a wireless set-top box. [0004] The present invention...
