Problems solved by technology

However, this automatic update function still has some limitations in the use of regions, often resulting in the following situation: because operators in some regions often have several sub-level operators in different townships or regions, these townships or regions are not for enriching local Due to the cultural characteristics of the region, it is necessary to add some self-managed programs to the signal broadcast by the front-end of the set-top box in the township or region, so the front-end needs to update the NIT table, but if the front-end updates the NIT table, it will cause set-top boxes in all subordinate regions Updates will be detected to enter the automatic search and automatically update the program list, causing the inconvenience of passive update for areas that do not need to update the program list

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0021] The cable digital TV system is mainly composed of a cable digital TV front end and a digital TV set-top box or a digital TV with a built-in digital TV set-top box function. The following uses the set-top box as an example to illustrate. The cable digital TV front end includes PSI (Program Specific Information, program-specific information) in the TS (Transport Stream, transport stream) that carries multiple TV program information, so that the set-top box can correctly find a specific TV from a certain TS stream. programme. In this embodiment, the cable digital TV front end inserts a private description about the program list update area into the PSI information released by it, so that the set-top box can determine whether the program list needs to be updated.

[0022] Specifically, such as figure 1 and figure 2 As shown, the ca...

Abstract

The invention relates to the field of set top boxes, and in particular relates to a method for updating a program list by the set top box. The set top box receives a transmission stream (TS) sent by a front end system; whether the set top boxes in all regions uniformly update the program lists is judged according to region information in peripheral service information (PSI) issued by a wired digital front end; and when only the set top boxes in partial regions are required to update the program lists, the program lists in partial regions are updated according to region numbers of the program lists to be updated in the region information. According to the updating method, a clear logic management hierarchy is involved, so that the set top boxes in different regions can update the program lists regionally, and the trouble that the set top boxes in different regions passively update the program lists is avoided.

Description

technical field [0001] The invention relates to the field of set-top boxes, in particular to a method for updating a program list in a set-top box and a method for updating a program list (distributing a program list) at a cable digital TV front end. Background technique [0002] In recent years, digital TV technology has developed rapidly, and the transmission standards of TV broadcast channels have gradually matured. With the widespread popularization of digital TV signals, more and more users use set-top boxes to receive digital TV signals. In a digital TV system, a user terminal needs to use a set-top box to receive digital TV programs broadcast by an operator. The set-top boxes on the market now have a simple program list automatic update function designed in the software, that is, to re-search for programs and automatically update the program list according to the version number change of the NIT table (Network Information Table) issued by the operator, so that if the ...
