Non-local program shielding method based on wireless set top box

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...
