Live video control method, equipment and system

Abstract

The embodiment of the invention discloses a live video control method, live video control equipment and a live video control system, wherein the method comprises the realization steps that a video server retransmits video frames from main broadcasting equipment to user equipment; the video server monitors whether the loss of key frames occurs in the video frames or not; if the video server monitors that the loss of key frames occurs, notification information is sent to the main broadcasting equipment for notifying the main broadcasting equipment of the loss of key frames so that the main broadcasting equipment sends recoded key frames. The video server monitors whether the loss of key frames occurs or not, then, the video server notifies the main broadcasting equipment of the loss of key frames, the main broadcasting equipment recodes the key frames so that the main broadcasting equipment can upload new key frames in time, and the phenomena of picture display incapability and screen fuzzyness caused by the loss of key frames are eliminated. The improvement on the occurrence frequency of the key frames is not needed, so the data transmission quantity can be reduced, the width requirement is reduced, and a network can be smoother.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video live broadcast control method, device and system. Background technique [0002] A frame is a single image frame in the smallest unit of video or animation, which is equivalent to every frame on a movie film. [0003] A key frame is a complete reservation of a frame of pictures. When decoding, only the data of this frame is needed to complete the display of a picture. Generally, it can be referred to as an I frame. The frame between two key frames is a non-key frame, which can generally be called a transition frame or an intermediate frame. The frame that records the prediction information in the transition frame is also called a prediction frame. The prediction information recorded according to the prediction frame can be used in the decoding process. Combining key frame decoding to obtain images, transition frames generally refer to P frames, B frames, etc. ...

AI Technical Summary

Problems solved by technology

[0006] Based on the above introduction, due to the large amount of key frame data, the above scheme increases the frequency of key frames (that is, shortens the interval between key frames), which will greatly increase the bit rate of the video, which will put extremely high requirements on bandwidth, even cause network congestion
