Abstract

Disclosed is an audio / video playback control method. The audio / video playback control method comprises the following steps: upon receiving an audio / video playback request sent by a mobile terminal, obtaining the preset feature data for audio / video playback from the audio / video playback request; obtaining the audio / video data to be coded by screening the audio / video data corresponding to the presently received bit stream according to the audio / video playback feature data; coding the audio / video data to be coded to form multimedia files; outputting the multimedia files to the mobile terminal for audio / video playback by the mobile terminal. Further disclosed is an audio / video playback control device. The present invention solves the problem that during multi-screen interaction a mobile terminal cannot perform playback due to the limitation of decoding capability of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of display terminals, in particular to an audio and video playback control method and device. Background technique [0002] At present, TV, computer and mobile phone are the three platforms that ordinary users are most exposed to in their daily life. They each have their own characteristics: large TV screen and good viewing experience; computer with many functions and abundant storage space; mobile phone is the most convenient to carry around. When users watch videos on TV at home, although the viewing experience is good, it is far less rich in operation and content resources than mobile phones and computers. The emergence of multi-screen interactive technology aims to integrate the advantages of the three platforms to achieve the best user experience. [0003] In the prior art, in the multi-screen interactive technology, usually each terminal directly obtains the original audio and video data, deco...
