Problems solved by technology

For P frames with low transmission quality requirements, these technical measures to ensure the quality of the transmission channel have caused a waste of transmission channel resources
[0014] It can be seen that code streams with different characteristics are transmitted on the same transmission channel, resulting in large changes in the bit rate of the transmission channel, which is not conducive to the design and management of the transmission channel by the system, resulting in low resource utilization efficiency of the transmission channel, especially a large number of P frames Existing code stream

Embodiment Construction

[0031] The core idea of ​​the present invention is: after the video signal is encoded by the source encoder, according to the characteristics of the code stream of the video coded signal, the sender separates the code streams with different characteristics, and the different code streams are transmitted through different transmission channels. On the receiving side, the code streams from different transmission channels are combined according to the order of the video coded signals before transmission, and then input to the source decoder for decoding and output.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0033] figure 2 It is a schematic diagram of the transmission principle of the video coded signal in the present invention, and the video signal is coded using the H.264 coding s...

Abstract

This invention discloses a method for transmitting video coding signal to adopt different transmission channel for different characteristic video coding signal code stream. Said method includes coding video signal by source encoder, the sender separating coded signal according to different character of video coding signal code stream, the separated code stream transmitted in different transmission channel, receiver merging code stream according to coding signal sequence before transmission, imputing in source encoder for decoding and then transmitting. Said invention reduces the bit rate change in transmission channel.

Description

technical field [0001] The invention relates to a video information processing technology, in particular to a transmission method of a video coded signal. Background technique [0002] A typical communication system consists of a sender, a source encoder, a channel encoder, a modem, a channel decoder, a source decoder and a receiver. [0003] The sending end generally includes voice, video, data and other forms. As a very special kind of information, video will play an increasingly important role in future communication systems. Applications such as video telephony, video conferencing and streaming media all contain a large amount of video information. [0004] A video service transmission process is realized in this way: the video coded information code stream after the source code is transmitted to the source decoder through the transmission system, and after decoding, it is delivered to the receiving end to complete the communication. The transmission system can be a wi...
