Abstract

The invention provides a method and device for generating an electronic program manual, a program searing method of a TV terminal and a searching engine. The searching method comprises: analyzing the digital TV front-end set-top box to receive from the transport stream TS packets, the TS packet contains program classification criteria, classification of programs and program information in order to receive program classification criteria, classification of programs and program information; be based on the analysis of the program to find the order of classification criteria at all levels of classification, search for the corresponding programs at all levels of classification and/or the next level of classification at all levels of classification, and search-based programs to extract the corresponding program information; in the digital television terminal interface on classification criteria in accordance with the program shows search programs. The invention of the search programs to increase the speed and accuracy.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a digital television EPG generation method and device, a digital television terminal set-top box program search method and a search engine. Background technique [0002] Global digital TV has entered a stage of rapid development, and services related to digital TV have also increased significantly. When digital TV can provide users with programs several times larger than current programs and various services, Electronic Program Guide (EPG: Electronic Program Guide) becomes an indispensable tool. EPG enables users to find desired programs conveniently, quickly and intuitively, and provides users with navigation services. When users are looking for programs, they only need to use the set-top box remote control to switch the TV screen to the EPG interface, and they can see the program name, broadcast time and program introduction of each digital TV channel within a period of time....
