Problems solved by technology

[0004] However, because the existing video encoding method encodes the video picture as a whole, it needs to encode all the pictures at the same frame rate, especially for some videos that basically do not change during the playback process of some pictures, there are problems such as long encoding time, low efficiency

Embodiment Construction

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] Considering that the traditional video encoding method encodes the video picture as a whole. In some occasions, there may be obvious differences between fast-moving parts and slow-moving parts in the video picture. For example, in the broadcasting scene of the announcer and the monitoring picture scene of the monitor, the background part hard...

Abstract

The present invention provides a video coding method and device, a decoding method and device, and a video transmission system. The video coding method includes the steps: acquiring a video frame of atarget video; dividing the video frame into at least two changing areas, wherein the change rates of the changing areas in the video frame are different; coding each of the changing areas at a framerate corresponding to each of the changing area to obtain a coded stream corresponding to each of the changing area, where the change rate of each changing area and the respective frame rate have a positive correlation therebetween. The method can effectively improve the efficiency of video coding and the pertinence of coding, thereby further improving the efficiency of video transmission.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a video encoding method and device, a decoding method and device, and a video transmission system. Background technique [0002] Video encoding (Video Encoding) refers to the method of converting a video format file into another video format file through a specific compression technology. Video technology has a wide range of applications, such as online video conferencing, online video e-commerce, online government affairs, online shopping, online schools, telemedicine, online seminars, online exhibition halls, personal online chat, visual consultation and other services. However, all of the above applications must be compressed. The amount of data to be transmitted is so large that it is unrealistic to simply expand the memory capacity and increase the transmission rate of the communication trunk line. Data compression technology is an effective solution. There...
