Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 As shown, the first embodiment of a program update method of the present invention is shown.

[0044] The program update method provided in this embodiment is mainly used for terminals to update programs. The type of the terminal can be set according to actual needs for receiving programs. For example, the terminal can be a digital TV set-top box, a digital TV all-in-one machine, a handheld TV terminal Wait for digital TV. The following will take the updating of TV programs by digital TV as an example to describe in detail.

[0045] The program updating method of the present embodiment includes the following steps:

[0046] Step S10, obtaining the program data table corresponding to the current frequency point, the program data table including the version number and program information;

Abstract

A program updating method. The program updating method comprises: acquiring a program data table corresponding to a current frequency point, the program data table comprising a version number and program information; after the program data table is acquired, acquiring a program data table stored in a server and a version number thereof; and when the version number of the program data table of the current frequency point is inconsistent with the version number of the program data table stored in the server, updating a program data table corresponding to each frequency point by means of the program information and version number in the program data table stored in the server, the program data table comprising program information about all the frequency points. Also disclosed is a program updating apparatus. A program can be updated at a current frequency point without frequency hopping updating, so as not to affect a user to watch the program.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a program updating method and device. Background technique [0002] At present, when updating a program, the terminal first jumps to the main frequency point to load the data of the NIT (Network Information Table, frequency-locked loading Network Information Table). When the version number in the NIT table at the main frequency point changes, jump to the program search interface to obtain PAT (Program Associate Table, program association table), PMT (Program Mapping Table, program mapping table) from each frequency point in turn , SDT (Service Description Table, Service Description Table) and other data to search for programs and save the programs found to update the program list. Therefore, when the terminal is searching for a program, the user has to terminate the current activity of watching the program. Contents of the invention [0003] The main purpos...
