Problems solved by technology

[0004] However, because the network conditions used to transmit compressed video streams fluctuate every moment, and the compressed video streams are pre-generated based on the previous feedback from the network, the estimated network capacity has a lag. Continuous time, it is difficult to adjust the video quality in real time, which may cause picture freezing and loss during real-time video

Abstract

The present invention discloses a video frame transmission method, system and server, wherein the video frame transmission method includes: the sending end obtains the original video data and the reference network information fed back by the receiving end; and the first code is determined according to the reference network information rate and a second bit rate; encode the video frames to be transmitted in the original video data according to the first bit rate and the second bit rate respectively, to obtain the first video frame corresponding to the first bit rate and the first video frame corresponding to the first bit rate A second video frame corresponding to the second code rate; obtaining current network information, matching the first video frame and the second video frame with the current network information to obtain a matching result; sending the matching result to the The receiving end sends the first video frame or sends the second video frame or does not send a video frame. The technical scheme provided by the invention improves the fluency and stability of video.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a video frame transmission method, system and server. Background technique [0002] With the rapid development of the Internet, real-time video technologies such as video conferencing, cloud video games, robot and vehicle remote control are also constantly improving. [0003] In the current real-time video transmission system, the sending end can use the transmission protocol to estimate the average data transmission rate in the network path, and provide the estimated value to the codec, and the codec determines the encoding parameters according to the estimated value, for example , bit rate, etc., and generate a compressed video stream according to the determined encoding parameters, so that the average bit rate of the generated compressed video stream is close to the estimated network capacity, and send the produced compressed video stream to the receiving end using the tr...
