Wireless television live broadcasting system and live broadcasting method thereof

Abstract

The invention discloses a wireless television live broadcasting system and a live broadcasting method thereof. The wireless television live broadcasting system mainly comprises a live broadcasting server, a forwarding server and a user terminal, wherein the live broadcasting server is used for converting live broadcasting information into streaming media data and sending the streaming media data; the forwarding server is used for receiving the streaming media data sent by the live broadcasting server and forwarding the streaming media data according to the HTTP (Hyper Text Transport Protocol); and the user terminal is used for sending an HTTP request to the forwarding server and watching live television according to the received streaming media data after being connected with the forwarding server through wireless network. According to the television live broadcasting system and the live broadcasting method, the forwarding server sends streaming media data to the user terminal through the HTTP, so that the defect can be avoided that the traditional broadband IP access network adopts the RTSP (Real Time Streaming Protocol) / RTP (Real-time Transport Protocol) to transmit multimedia data, so that the number of file headers is large, and signalling interaction is cumbersome.

Description

technical field [0001] The invention relates to the field of live TV broadcasting, in particular to a wireless TV live broadcasting system and a live broadcasting method thereof. Background technique [0002] With the development and popularization of wireless networks, there is an increasing demand for watching wireless video such as live TV and real-time video and voice chat with mobile phones. However, traditional broadband IP Internet access mainly uses Real-time Streaming Protocol / Real-time Transport Protocol (RTSP / RTP, Real-time Streaming Protocol / Real-time Transport Protocol) to transmit multimedia data such as live TV or video and voice. [0003] However, wireless network clients such as mobile phones use GPRS for data transmission, and the transmission code rate is low, generally around 30Kb / s. If RTSP / RTP protocol is also used for multimedia data transmission, there will be many defects. Because the RTSP / RTP protocol has a large number of file headers (Overhead), ...

AI Technical Summary

Problems solved by technology

[0003] However, wireless network clients such as mobile phones use GPRS for data transmission, and the transmission code rate is low, generally around 30Kb / s. If the RTSP / RTP protocol is also used for multimedia data transmission, there will be many defects

Because the RTSP / RTP protocol has a large number of file headers (Overhead), such as transmitting 10M useful data, there will be a 2M file header, which invisibly increases the burden of wireless network transmission; and the RTSP / RTP protocol has a large number of signaling interactions, such as To receive a piece of data, the client needs to interact with the server multiple times, and multiple signaling interactions will also increase the burden of wireless network transmission; and the RTSP / RTP protocol has a large number of signaling interactions, and the CMWAP developed by China Wireless Does not support a large number of signaling interactions, so mobile clients using CMWAP to connect to the network will not be able to use CMWAP to connect to the network to watch live TV

[0004] Although some high-end mobile phone clients can support RTSP / RTP protocols to watch live TV, they require fast and stable wireless network communication quality, and relatively high requirements for mobile phone software. If the general mobile client or network is normal, Still can't watch live TV smoothly
