Mobile broadcast network system and method for implementing synchronous of the network

Abstract

The invention discloses a mobile broadcasting network system and a method for synchronizing the system. The system includes: a content provider, which provides and sends program information with broadcast time requirements; a regional service terminal, which receives the broadcast time sent by the content provider and program information, the regional service end generates a MAC data packet with a time stamp according to the broadcast time and program information, and sends it to each base station under its jurisdiction with the same reference time; each base station detects that the time stamp of the MAC data packet is within the time In the window, the MAC data packet is put into the buffer, and the MAC data packet is sent when the time specified by the timestamp is the same as the base station's reference time, otherwise the MAC data packet is discarded. The present invention adopts the same reference time at the program sending end, the regional service end and the base station, adds the playing time requirement to the program information, and adds the playing time stamp to the MAC packet of the program data to ensure the time difference between different areas and different communities. Synchronized playback between programs.

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...
