Embodiment Construction

[0047] The present invention provides a mobile broadcasting network system and a method for realizing network synchronization, so as to solve the delay error in the same content sent by the same frequency network (SFN) adjacent cell base station existing in the prior art, and then cause out-of-synchronization The problem of mutual interference between programs. The present invention adopts the method of adding a time stamp to the broadcasting program to make precise regulations on the time of playing the program data, and can detect the time stamp at the base station to ensure the synchronization of the program broadcasting in each community, and to avoid the time stamp in adjacent areas. There is a phenomenon that the programs interfere with each other and are not synchronized.

[0048] In order to solve the problems existing in the prior art and realize the purpose of the present invention, the present invention proposes a mobile broadcasting network system, the structural b...

Abstract

This invention discloses a mobile broadcast network system and a method for synchronization, in which, the system includes: a content providing end providing and sending program information with the requirement of playing time, a region service end receiving the play time and program information sent by the content providing end and generating MAC data packets with timestamp and sending them to base stations governed by it to transmit the MAC data packets within the time appointed by the timestamp, which applies same primary time at the program transmission end, region sservice end and base stations and adds requirement on playing time in program information and attaches timestamp on the MAC data packet to guarantee synchronous play of programs among different regions and local areas.

Description

technical field [0001] The invention relates to information communication technology in the field of information transmission, in particular to a mobile broadcast network system and a method for realizing network synchronization. Background technique [0002] With the rapid development of information and communication technology, there are more and more ways for people to learn about information, such as the Internet and radio and television. However, radio and television have been operating in a fixed mode until the rise of mobile TV technology. The concept of mobile TV includes not only mobile phone terminals, but also other types of mobile terminals (such as vehicle-mounted equipment, notebook computers, hand-held personal terminals, etc.). [0003] Mobile TV can also be called mobile TV service, which is a specific application of digital technology. Through the transmission of digital signals, the image quality is clearer and the image reception is more stable. Mobile TV...
