Abstract

The invention provides a time synchronization method, a television and an EPG (Electronic Program Guide) server. The method comprises the steps of receiving first EPG information sent by the EPG server, wherein the first EPG information comprises a first system time when the first EPG information is sent by the EPG server, and a first system time difference between the EPG server and a program source server; according to a first device time when a television requests the EPG server for the first EPG information and a second device time when the television receives the first EPG information, and determining a second system time difference between the television and the EPG server; and according to the first system time, the first system time difference and the second system time difference, realizing time synchronization between the television and the program source server. According to the time synchronization method, the television and the EPG server provided by the invention, the time synchronization between the television and the program source server is realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a time synchronization method, a television and an EPG server. Background technique [0002] At present, there are more and more types of programs that can be played by smart TVs, including live TV programs from traditional signal sources and program resources in the network. Therefore, the user has more and more options for the television programs to be watched. The programs of the network carousel channel may come from multiple program source servers distributed in different geographical regions. [0003] In the prior art, the smart TV can periodically obtain EPG information from the Electronic Program Guide (EPG) server side, and then play the channel selected by the user according to the EPG information. The source server obtains the video code stream. The EPG information on the EPG server side is EPG information in a unified format that is formed by rearranging and ...
