Problems solved by technology

This aspect is not applicable to the real-time video stream control of the national standard platform. On the one hand, this control method requires information on the delay and packet loss rate. If the delay of these information is large and is being adjusted, it will be difficult to achieve the desired effect. On the other hand, Based on the GB28181 national standard platform, it is difficult to adjust the code stream of the sender in real time, and it is necessary to adjust and modify the received video stream

Embodiment 1

[0043] Such as figure 1 As shown, the present invention proposes a real-time video stream self-adaptive coordination system and method, aiming at the problems of the real-time video stream data acquired on the GB28181 national standard platform often causing stuttering and video quality jitter. According to the current packet loss situation, the obtained video stream data is adjusted to make the video more balanced and improve the video quality.

[0044] The real-time video stream self-adaptive coordination system described in the present invention, the system is applied to the GB28181 national standard platform, and the GB28181 national standard platform connects two non-national standard monitoring equipment and monitoring networking platforms of different communication protocols of the system, wherein:

[0045] Non-national standard monitoring equipment, including a number of cameras that send video streams, the video streams are compressed into numerous video units including...

Abstract

The invention relates to a real-time video stream adaptive coordination system and method, and belongs to the technical field of video signal transmission. The system comprises a non-national standard monitoring device which comprises a plurality of cameras for sending video streams; the monitoring networking platform comprises a video stream optimization and adjustment module and a monitoring networking display module, the video stream optimization and adjustment module obtains the sent information packet digital code, the lost information packet digital code and the jitter condition of the information packet from the national standard platform through the RTCP protocol, and the frame loss condition of the current video stream can be judged through the information; and the video stream optimization and adjustment module optimizes video stream lagging caused by frame loss through a frame number dynamic planning algorithm. According to the method, the smoothness of the real-time video stream can be improved, and the picture lag caused by frame loss is optimized through a frame number dynamic planning algorithm, so that the picture is smoother and more balanced, and the method is effectively applied to real-time video stream monitoring of a national standard platform.

Description

technical field [0001] The invention relates to a real-time video stream adaptive coordination system and method, belonging to the technical field of video signal transmission. Background technique [0002] GB28181 is a communication protocol standard designated by the country for the security field, the purpose is to solve the problem of inconsistent communication protocols of different platforms and different devices. Streaming media technology refers to a technology that compresses a series of media data and transmits them in segments in the network in a streaming manner, so as to realize real-time transmission of audio and video on the network for viewing. [0003] At present, real-time video streaming data is required for monitoring and live broadcasting. Due to the unreliable conditions of the Internet, its bandwidth and load change drastically, which makes it difficult to make the streaming media bandwidth approx. It has high requirements for real-time performance, n...
