Online live video player and method

Abstract

The invention provides an online live video player. The online live video player comprises a player interface component which is used for receiving a playing time adjustment instruction, a protocol switching component which is used for determining whether a current first stream media transmission protocol is switched to a second stream media transmission protocol according to the playing time adjustment instruction, and a playing control component which is used for carrying out video live broadcast or replaying according to the stream media transmission protocol determined by the determining result of the protocol switching component. The first stream media transmission protocol is selected from one of a live broadcast stream media transmission protocol and a replaying stream media transmission protocol, while the second stream media transmission protocol is the other. The invention further provides a corresponding video playing method. According to the invention, two protocols are used for switching; the characteristic of great live broadcast instantaneity of the stream media real-time transmission protocols is used; delay time produced by replaying in live broadcast in the prior art is reduced; and dual demands of live broadcast and replaying at any time are perfectly met.

Description

technical field [0001] The invention relates to the video field, in particular to an online live video player and method. Background technique [0002] With the development of computer technology, currently online live video players are usually streaming media players that utilize streaming media technology to play on the network. Streaming Media (SM for short) technology is a data transmission technology that sequentially compresses a series of media data packets and sends them to a terminal in segments. The terminal receives multiple streaming media packets sequentially like an assembly line and decompresses and plays them sequentially. Compared with the ordinary "download first, play later" playback mode, streaming media technology can realize online playback of audio and video files. Common streaming media transmission protocols used by online live video players during playback include smooth streaming protocol, mms protocol, HLS protocol, HTTP protocol, RTSP protocol, ...

AI Technical Summary

Problems solved by technology

[0007] The embodiment of the present invention provides an online live video player, which is used to solve the defects in the prior art that the live video cannot be watched back when using the streaming media live broadcast protocol, and that there is a relatively large delay when using the streaming media on-demand protocol for live broadcast and playback. Realize the way to switch between the two protocols for live broadcast and playback of video
