Problems solved by technology

However, this method cannot work in one-to-many video communication systems such as video conferencing, because if the bandwidths of multiple receiving terminals are very different, the sending terminal will not be able to encode and generate a video that meets the bandwidth requirements of all receiving terminals. stream

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 2 A schematic flowchart of a method for video encoding, video code stream adaptive transmission and display according to an embodiment of the present invention is shown. like figure 2 As shown, the video coding, video code stream adaptive transmission and display method according to the embodiment of the present invention includes three stages of coding, transmission and display. In order to illustrate the method more clearly, it is assumed in the following description that a server relay communication mode is adopted in the video communication process.

[0032] 1. Coding stage

[0033] In this stage, divide and conquer strategy is adopted, including two parts of video stream segmentation and video stream encoding.

[0034] (1) Video stream segmentation

[0035] Divide the original video stream V into n video streams, so ...

Abstract

The invention provides a video coding method which comprises the steps of a first step, dividing a to-be-transmitted original video stream V into n sub-video streams V1,...Vn, wherein each sub-video stream comprises different pixels in the original video stream, and n is an integer which is larger than 1; and a second step, coding the sub-video streams, thereby forming a plurality of sub-video code streams. The invention correspondingly provides a video code stream adaptive transmission method which corresponds with the video coding method, and a display method. The video coding method can perform adaptive combination in transmission according to a bandwidth value. Not only can available bandwidth be utilized maximally, but also video lag and mosaic caused by bandwidth bottleneck can be prevented.

Description

technical field [0001] The present invention relates to the technical field of video communication, in particular, the present invention relates to a video coding method, a video code stream adaptive transmission method and a corresponding display method. Background technique [0002] With the development of mobile terminals and network technologies, especially the rapid development of 3G / 4G mobile wireless networks, video communication in heterogeneous networks is becoming more and more popular, such as figure 1 shown. Traditional video communication systems generally use peer-to-peer network access, and the access bandwidth of terminals is similar, and the bandwidth is relatively stable. The unified video code stream generated by the sending terminal can meet the bandwidth requirements of all receiving terminals. However, the access bandwidth of the heterogeneous network is high or low, and the stability of wireless access is also poor. Traditional video communication met...
