A streaming media transmission method, device and system thereof

Abstract

The present invention provides a streaming media transmission method, comprising: a streaming media sending device simultaneously encodes the first stream and the second stream according to the network state to form a first code stream and a second code stream; respectively packs and buffers the first code stream A code stream and a second code stream form a first code stream buffer and a second code stream buffer, wherein the time lengths of the first code stream buffer and the second code stream buffer are the same; The media receiving device sends the data of the first time period buffered in the first code stream; and updates the second code stream buffer every second time period. The present invention dynamically adjusts the cache length and key frame interval according to the network state, so that the displayed image can be transmitted with higher quality when the network state is not good, and at the same time, the displayed image can be quickly restored in the case of packet loss.

Description

technical field [0001] The present invention relates to the field of streaming media data transmission, in particular to streaming media network transmission technology, in particular, but not constituting a limitation to the present invention, to a streaming media encoding and decoding technology. Background technique [0002] Now streaming media in the case of poor network status, such as a large delay or packet loss, the common method is to increase the I frame ((I frame) by analyzing the network status when the network status is not good It is also known as the interval of an intra picture (a complete image can be decoded alone) so that the streaming media receiving device will not be stuck for a long time when playing. But this solution will bring some problems. Increasing the I frame will increase the load pressure of the network. Doing so when the network state is already bad will make the state of the network further deteriorate, and this problem has not been solved ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned defects of streaming media transmission stuck and blurred screen caused by poor network status, the present invention provides a method, device and system for streaming media transmission, the purpose of which is to provide higher quality Transmission of displayed images can reduce the load pressure on the network at the same time, making the decoding and playback screen of the streaming media receiving device smoother, and can also quickly restore the displayed image in the event of packet loss
