METHOD AND SYSTEM FOR REALIZING SYNCHRONIZATION BETWEEN RECEIVER AND SOURCE OF BROADCASTING TV SERVICE

摘要

The invention discloses a method and a system for realizing the synchronization between a receiver and a source of the broadcasting TV service. The invention mainly includes the following steps: first, determining the time difference information between a program source and a transmitter on the transmitter, and transmitting the time difference information and its own time information from the transmitter to the receiver; finally, realizing the synchronization with the program source by the receiver based on the time difference information and the time information of the transmitter. Realization of the invention can ensure that the synchronization between the program source and the receiver is realized in a broadcasting TV service network, thus a user receiver can obtain accurately precise starting time information of the program stream which the receiver receives from the program source. The method of the invention is simple and it is easy to realize the method , and it is convenient to operate the method, and the invention effectively avoid the problem of energy waste resulted in that the receiver need turn on the device in advance for receiving the corresponding program.
