Embodiment Construction

[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0053] The invention provides a video quality optimization method.

[0054] Reference figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the video quality optimization method of the present invention.

[0055] In this embodiment, the video quality optimization method includes:

[0056] Step S10: When the video frame freeze time of the first client exceeds a first preset time, the first client sends an instruction to reduce the bit rate to the second client, so that the second client can follow The instruction to reduce the code rate returns a response;

[0057] When the user of the first client and the user of the second client are in video communication, the network transmission capacity of the second client to send video data drops sharply, that is, when the network condition is in a congested s...

Abstract

The invention discloses a video quality optimizing method. The method comprises the steps that when video frame jamming time of a first client exceeds first preset time, the first client sends a code rate reducing instruction to a second client, so that the second client returns response according to the code rate reducing instruction; when the response returned by the second client is received, whether the present network is in an unblocked state is determined according to a preset algorithm; and when the present network is in the unblocked state, a code rate recovering instruction is sent to a second client, so that the second client transmits video data to the first client according to the code rate in the unblocked state. The invention also discloses a video quality optimizing device. When jamming occurs in the present video frame, the sharpness of the video frame is reduced to prevent serious frame jamming, and user experience is improved.

Description

Technical field [0001] The present invention relates to the technical field of video networks, in particular to a video quality optimization method and device. Background technique [0002] With the popularity of smart TVs, video chat applications on smart TVs are becoming more and more accepted and well-known. Because the operation of video chat on smart TV is simple, there is no need to care about power consumption and traffic, and the screen is large enough to bring a video conference-like experience. Therefore, more and more users like to video chat on smart TV. However, because smart TVs are limited by their own hardware and software conditions and the uncertainty of network conditions, there are also uncertainties in video quality. When the smart TV is in a good network condition, the video quality is usually no problem; and when there is a small amount of packet loss (within 20%) or a slight delay (within 1s) on the network, the picture may have a certain delay and jam H...
