Problems solved by technology

[0002] At present, when transmitting media streams on the Internet, due to problems such as large data volume and unstable network bandwidth, the transmission rate is very slow, and even transmission failures occur, making it difficult for users to obtain the information they want.
The current technology to solve this problem is mainly to use buffering technology to wait until all the data arrives before sending it to the user. In this way, the user sometimes has to wait for a long time and cannot see what they want, and the data is lost when it reaches the user. Real-time, and some methods of using algorithms to drop frames are more complicated and difficult to implement

Embodiment Construction

[0022] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0023] As shown in Figure 1, the video terminal is connected to the main server of the operator through Ethernet, and a buffer pool for storing video data is implemented on the main server by software. The user terminal is any terminal device that can be connected to the server. The link with the server can be realized through GPRS / CDMA / GSP, or ADSL, etc. Suppose a user terminal needs a video information, it sends a request to the operator server through GPRS / CDMA / GSP or ADSL, etc., the server receives this command, and forwards the request to the video interception terminal, and the video terminal receives this command. Start to package the intercepted video stream into data packets and send them to the server. The server sets up a buffer pool for each video terminal to save the data. At the same time, the server sends the cached data back to the user terminal. At t...

Abstract

The invention discloses a self-adapting method of media stream transmission bandwidth and pertains to the data communication field. In remote transmission media flow process, the method sets up a buffer pool of a media flow data packet on a master server and decide the bandwidth condition of the networks on both sides of the master server, according to the time interval of the data packet arriving at the buffer pool and the data volume stored in the buffer pool currently and then, performs self-adapting transmission. The main steps are: 1) a user terminal sends out a request order to the master server, which analyzes the order; 2) after the request order analysis, the master server sends out an order of reading out a video message to a video terminal by Ethernet; 3) after receiving the order, the video terminal transmits the data packet of the obtained video data to the server buffer pool with certain velocity; 4) the server responds to the request from the user terminal and realizes data transmission. The media flow transmission realized by the method can guarantee the user obtaining the data packet with enough message volume in time in network congestion, with easier implementation.

Description

technical field [0001] The invention relates to a method, that is, in the process of long-distance transmission of media streams, by setting a buffer pool of media stream data packets on a general server, and then judging the bandwidth status of the network according to the amount of data currently stored in the buffer pool, and then automatically Adapted transmission. technical background [0002] At present, when transmitting media streams on the Internet, due to problems such as large data volume and unstable network bandwidth, the transmission rate is very slow, and even transmission failures occur, making it difficult for users to obtain the information they want. The current technology to solve this problem is mainly to use buffering technology to wait until all the data arrives before sending it to the user. In this way, the user sometimes has to wait for a long time and cannot see what they want, and the data is lost when it reaches the user. Real-time, and some met...
