Problems solved by technology

However, when the network channel itself is already congested, the SR / RR packets that come and go once in a while may also be lost. As long as the SR / RR packets lack one of them, the effective packet loss rate information cannot be obtained, resulting in code The rate cannot be adjusted in time

Abstract

The invention discloses a video code rate adjustment method, comprising: counting the packet loss rate and the received video code rate according to the packet header information of the received real-time transmission protocol packet; according to the packet loss rate and the received video code rate Generate an information packet at a high rate; send the information packet so that the receiving end obtains the packet loss rate and the video bit rate of the sending end according to the information packet, and adjusts the receiving end according to the packet loss rate and the video bit rate of the sending end end video bit rate. The invention can realize accurate and rapid self-adaptation adjustment of the video code rate in the communication process. The embodiment of the invention also discloses a video code rate adjustment system, a terminal and a storage medium.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to a video bit rate adjustment method, system, terminal and storage medium. Background technique [0002] In the field of network communication, in order to ensure the real-time timeliness of video images, general network video communication systems use UDP (User Datagram Protocol) to send RTP (Realtime Transport Protocol) / RTCP (Realtime Transport Control Protocol) packets for data transmission and instructions control. However, since UDP transmission does not have a channel blockage detection and elimination mechanism, when the network is unstable and leads to blockage, packet loss will occur, which will eventually lead to problems such as freezes, mosaics, and screen delays when decoding at the receiving end. [0003] In the prior art, in order to solve this phenomenon, the video communication system obtains the packet loss rate by periodically sending ...
