Abstract

The invention belonging to the technique area of the computer multi-media includes following steps. (1) Nagle algorithm for closing the sending end of the stream media. (2) Deleting the transmissio control function of the real-time transmission control protocol in the RTPprotocol as well as changing the content of the sequence number parameter space, making the load content be changed from the sequence number to the length of the data message. (3) According to the changed RTP data format, the sending end transmits the stream media data message. (4) Based on the length of the data message indicated by the parameter at the head of the RTP data message, the receiving end receives sectionally RTP massage in TCP message. With the received and not integral RTP messages being assembled, the data in the assembled RTP message are decoded. The invention increases the transmission reliability of the stream media.

Description

technical field

[0001] The invention belongs to the technical field of computer multimedia, in particular to a streaming media transmission method. Background technique

[0002] To transmit multimedia information such as audio and video on the network, there are currently two schemes for downloading and streaming. Audio and video files are generally large, so the required storage capacity is also large, and due to the limitation of network bandwidth, the download time is also very long. In recent years, in order to solve the above problems and adapt to the development trend of network multimedia, streaming media technology has emerged as the times require.

[0003] The streaming transmission method of streaming media technology realizes the continuous and real-time transmission of audio, video or animation and other multimedia from the audio and video server to the user's computer. Start the time-lapse to watch. Streaming media technology not only shortens the start-up de...
