Video transmission method, play method, terminal and server

Abstract

The invention discloses a video transmission method, a play method, a terminal and a server, and belongs to the field of streaming media. The transmission method comprises the following steps: receiving the current network and resource parameters of the terminal when the server transmits the current video segment to the terminal; obtaining video stream of the next video segment according to the starting timestamp of the current video segment and the obtained current network and resource parameters, wherein the grade of the video stream of the next video segment corresponds to the current network and resource parameters; and transmitting the next video segment to the terminal by the server when the current video segment is transmitted. According to the invention, video streams can be dynamically provided along with change of bandwidth and decoding capacity of the accessed terminal. Videos with higher quality can be provided if the bandwidth is great and the decoding capacity is strong, while videos with poor quality can be provided if the bandwidth is small and the decoding capacity is weak, so that the resources are adequately utilized and the video experience of users is improved.

Description

technical field [0001] The invention relates to the field of streaming media, in particular to a video transmission method, a playback method, a terminal and a server. Background technique [0002] With the development of network technology, video websites provide users with more and more video resources, and in order to meet the access needs of most mobile Internet terminals, video websites will transcode the video resources provided on the Internet into Videos with low bit rate, low compression efficiency, and poor quality, and then provide these pre-transformed videos to mobile Internet users in the form of streaming media. While improving compatibility, the video effect is greatly sacrificed, and it does not It can make full use of the dynamically changing resources of the mobile Internet access terminal, especially the network bandwidth. Contents of the invention [0003] The embodiment of the present invention provides a video transmission method, a playback method,...
