Abstract

The invention relates to a digital image processing and video displaying technology, solves the problem of poor program changing experience of users in the prior art and provides a program searching method of a digital television set-top box. The technical scheme includes that the digital television set-top box receives information from an NIT (network information table) of a front-end server, the NIT includes private description characters, and the description characters comprise service ID (identity) information, service program package marks and service program frequency points in mutual correspondence. In searching programs, only program information matched with the service program package marks and the service ID information are stored in a program list of the digital television set-top box. The program searching method of the digital television set-top box has the advantages of convenience for users and applicability to the digital television set-top boxes.

Description

Technical field [0001] The invention belongs to the technical field of digital image processing and video display, and specifically relates to a program search method for a digital television set-top box. Background technique [0002] With the continuous development of digital TV technology, digital TV set-top boxes are used by more and more users and become the main way to watch TV; digital TV programs are becoming more and more abundant, generally as many as 100 sets. Under normal circumstances, the digital TV set-top box program will save all the searched TV programs in the program list, but users will often encounter unauthorized encrypted programs that cannot be watched during the channel change process, which affects the user experience. Summary of the invention [0003] The technical problem to be solved by the present invention is to propose a digital TV set-top box program search method to solve the problem that there are too many programs in the program list in the tradi...
