Efficient transmission system for online competition rebroadcasting

Abstract

The invention belongs to the technical field of competition rebroadcasting systems or video transmission methods, and particularly relates to an efficient transmission system for online competition rebroadcasting. The system comprises a video coding layer and a transmission control layer. The video coding layer at least comprises a coder module and a decoder module; the transmission control layer at least comprises a data sending module connected with the encoder module and a data receiving module connected with the decoder module; and the invention provides an efficient transmission system for online match rebroadcasting, which is high in coding and decoding efficiency, small in total data volume of video transmission, and capable of reducing network transmission pressure and improving the smoothness of online match videos. Through a system structure of a traditional reference coding scheme, a better optimization scheme is provided at the same time, the data compression efficiency is further improved, and the continuity and stability of continuous transmission of competition videos are ensured.

Description

technical field [0001] The application belongs to the technical field of event broadcasting system or video transmission method, and in particular relates to an efficient transmission system for online event broadcasting. Background technique [0002] With the rapid development of domestic wireless network transmission technology, there are more and more audio transmission tasks that require continuous large-scale data transmission and encoding and encoding, including sports rebroadcast video and panoramic VR video. At the same time of information, it also puts a lot of pressure on the network transmission system. In order to improve the data transmission speed, multi-channel synchronous or asynchronous transmission schemes continue to emerge. Using intelligent adjustment of network efficiency and transmission channels can avoid single-channel congestion. , but the multi-channel data processing method for data segmentation also puts forward new requirements for video encodin...

Problems solved by technology

As a basic video encoding and decoding scheme, using reference images or videos, inter-frame or intra-frame prediction through reference frames to achieve compressed video capacity, compressing redundant data is an emerging video processing scheme, but this scheme is still not yet available. There is a lack of a sufficiently complete and feasible transmission scheme, and compared with the original video, the video or image used for reference needs to occupy a certain amount of network capacity, so how to select a suitable reference image is also a problem
