Method for improvement of network video quality with bandwidth self adaption

Abstract

The invention relates to the network video field, particularly to a method for improvement of network video quality with bandwidth self adaption. The method comprises: a video sharing client collects coding video data and sends the data to a transmission server; the transmission server detects and analyzes network situations, classifies the network situations into a plurality of grading factors in an order from a poor one to a good one, and feeds back the network grading factors to the a video sharing client; the a video sharing client carried out layered compression based on the network grading factors, wherein the layers include a base layer and a weight layer; the transmission server transmits layered image information to a video watching client; the video watching client carries out coding fusion on a layered image; and a video server receives a video sharing request instruction sent by the video sharing client and a video watching request instruction sent by the video watching client. With the method, self adaption of various bandwidths is realized; and the higher image quality for an image key region is obtained.

Description

Technical field [0001] The invention relates to the field of network video, in particular to a method for self-adapting bandwidth to improve network video quality under complex network conditions. Background technique [0002] With the continuous development of information technology, network video calls have become an indispensable tool in life and work. However, the network bandwidth situation is complex and changeable. How to obtain better video call effects under complex network conditions has always been a problem. Commonly used network video calls have many defects, such as video freezes, screens, and screens when the network is poor. Blurring and other phenomena. When the network is good, the video is still blurry and unclear. When the main body of the video is not distinguished from the video background, the main body of the video cannot be highlighted. Therefore, how to design a method that can adapt to the network situation and improve the quality of the network video b...

However, the network bandwidth is complex and changeable. How to obtain better video call effects under complex network conditions has always been a problem. Commonly used network video calls have many defects, such as video freezes, blurred screens, etc. when the network is poor. Blur and other phenomena, when the network is good, the video is still blurred and unclear, and the video subject cannot be highlighted when there is no distinction between the video subject and the video background. Therefore, how to design a method that can adapt to the network situation and improve the quality of network video becomes a basic Technical problems that need to be solved urgently
