Abstract

The invention provides a video data transmission method and device, an edge service node and a medium. The method comprises the following steps: caching video data to be sent to a video data receivingend from a video data sending end; obtaining channel state information between the video data sending end and the video data receiving end; when the channel state information satisfies a first predetermined condition, obtaining a capacity-reduced version of cached video data, the transmission capacity of the capacity-reduced version being lower than the transmission capacity of the cached video data, but ensuring the decoding of the video data; and sending the capacity reduction version to a video data receiving end for decoding by the video data receiving end. According to the embodiment ofthe invention, the video data to be sent to the video data receiving end is cached, the channel state information between the sending end and the receiving end is automatically monitored, and when thechannel state indicated by the channel state information is poor, the capacity-reduced version of the cached video data is sent, so that the video playing fluency is ensured, and the jamming is avoided.

Description

technical field [0001] The present disclosure relates to the technical fields of computer and communication, and in particular, to a video data transmission method, device, edge service node and medium. Background technique [0002] With the rapid development of information technology, the form of expression and transmission of information has changed: from the traditional text (such as: books, newspapers) and audio (such as: broadcasting), etc., to more vivid and expressive Informative video way. Today's TV and the Internet present and share rich and comprehensive resources such as various film and television programs, news, advertisements, chats, education, and games in the form of video, so that video has become an irreplaceable and important tool for people to learn, socialize, and entertain. Way. [0003] However, due to the large video capacity, when the network status of the receiving end is not good, it is difficult to quickly process and display the received video...
