Media stream real-time pushing method and server

Abstract

The invention discloses a media stream real-time pushing method and a server. The method comprises the steps that a media segment is generated, an initial media segment is generated, a new media segment is generated according to feedback of a client and generation conditions of media units, at least one media unit is packaged in the media segment, and the feedback of the client comprises an indication that data is received in the media segment; and the generated media segment is sent to the client and feedback of the client is received, and at least one transmission connection with the clientis established by adopting a preset network transmission protocol so as to transmit the generated media segment by using the at least one transmission connection. According to the pushing method provided by the embodiment of the invention, self-adaptive segmented pushing of the media stream can be realized, various network transmission protocols are supported, and the transmission efficiency of the media stream and the transmission performance in a complex network environment are improved.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a method and server for real-time pushing of media streams. Background technique [0002] With the rapid development of the Internet, especially the mobile Internet, real-time transmission of multimedia data such as audio, video, and images through the Internet has become a basic requirement for many applications. In order to meet this demand, various real-time streaming media transmission technologies have been proposed. The originator of the transmission is different. These streaming media real-time transmission technologies can be divided into two categories: one is the stream pull method. The basic principle is that the client actively requests real-time data from the server. The technical solutions using stream pull are: Apple Inc. HLS (HTTP Live Streaming) proposed by Microsoft, Smooth Streaming proposed by Microsoft, HDS (HTTP Dynamic Streaming) pr...

Problems solved by technology

In various related push schemes, once the media data is generated, it will be sent to the sending buffer immediately. However, if the data volume of a single media unit is small, frequent single push will increase the network transmission overhead and reduce the transmission efficiency.

[0006] 2. Only a single network transmission protocol is used, which cannot adapt to various complex network environments

First of all, due to the settings of routers and firewalls in the Internet, only specific transmission protocols can be used between the server and certain clients, and the server needs to select different network transmission protocols for different clients; secondly, when the terminal where the client is located passes through When a wireless network accesses the Internet, the signal quality of its access link will vary with the location of the terminal. Correspondingly, the network transmission bandwidth, transmission delay and packet loss rate will also change, which cannot be guaranteed by using only one network transmission protocol. Service performance, such as when the link packet loss rate is high, the TCP transmission efficiency is very low, or even unable to work

[0007] 3. Only use a single transmission connection, resulting in cumulative delay

For RTMP or HTTP-FLV, it is necessary to establish a TCP connection before transmission and use the connection during the entire transmission process, which can easily lead to cumulative delay, that is, when network congestion occurs, the data packets that are too late to be sent are accumulated Up, blocking the transmission of subsequent data packets

Although the above problems can be compensated by clearing the cache and disconnecting and reconnecting, this will cause the loss of all data in the cache
