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 non-local program shielding method based on a wireless set top box. Through description of an SDT table in an MEPG2 standard, the provider name function of the table is expanded, and the purpose of shielding non-local programs is achieved. The method includes the following steps that firstly, through a multiplexer at the front end of an operator, unique identification information of a provider name is changed or added to the SDT table; secondly, the set top box starts search and analyzes the SDT table, and then the provider name is acquired; thirdly, whether the analyzed provider name is identification of the operator is compared so as to judge whether the name of the operator is correct or not; fourthly, according to the result in the third step, if the name the operator is correct, programs are saved, or else the programs are not saved. According to the non-local program shielding method, operator management and client expansion are convenient, later maintenance and operation are facilitated, the bandwidth is not occupied, cost is not increased, and the method is convenient to implement 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...
