Method and system of video transmission

Abstract

Provided are a method and a system of video transmission. The method includes the steps that frame pictures of a transmission video are acquired according to an original video; circumscribed polygons of displacement of moving objects and position information of the moving objects in the frame pictures are calculated; according to the position information, background pictures of the circumscribed polygons are collected, and moving objects videos of all frame pictures inside the circumscribed polygons are collected; and the video transmission is conducted according to the position information, the background pictures and the moving object videos. According to the method and the system of the video transmission, video data of the minimum region of the displacement of the moving objects of the transmission video are transmitted, images, except for the minimum region, only need to be transmitted for one time, transmission of the redundant data size of the background part is reduced, transmission data are effectively reduced, and speed and efficiency of the video transmission are improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video transmission method and system. Background technique [0002] There is a large amount of redundant information between adjacent frames of video images. In the field of video processing technology, although the H.264 standard proposes many advanced video compression methods for video, which removes a large amount of redundant information within and between frames, but These compression methods are at the cost of high computational complexity, which reduces video compression and decoding efficiency, and limits the effect and quality of real-time video transmission. [0003] In the patent document whose publication number is CN102724492A, it is disclosed that a background image and a moving image are respectively extracted from the frame image of the original video stream; the moving image and its corresponding coordinate position information and the extract...

Problems solved by technology

[0004] However, in practical applications, there is a large range of movement in the video image movement. If the range of the changing area is large, the use of this technology will lead to excessive video data processing and information capacity, thereby reducing the transmission efficiency of video image information.
