Different-end audio and video playing method, device and audio and video playing system

Abstract

The embodiment of the invention provides a different-end audio and video playing method, a device and an audio and video playing system. The different-end audio and video playing method is applied tofirst equipment. The method comprises the steps of acquiring audio and video data; simultaneously sending the audio data and the time delay detection data to second equipment by utilizing a first communication protocol, so that the second equipment returns time delay response data and caches the audio data after receiving the audio data and the time delay detection data, and playing the audio dataafter a preset caching duration; receiving data based on the time delay response data, obtaining the playing time delay of playing the audio data by the second device, wherein the time delay responsedata comprises feedback data corresponding to the time delay detection data and preset cache duration; and playing the video data after the playing time delay. According to the scheme, the effect ofaudio and picture synchronization during different-end audio and video playing can be achieved.

Description

technical field [0001] The present invention relates to the technical field of audio and video playback, in particular to a method, device and audio and video playback system for heresy audio and video playback. Background technique [0002] When using an electronic device to play audio and video data, the electronic device may play abnormally the audio data in the audio and video data. For example, when the audio data needs to be played with headphones, the electronic device cannot be connected to the headphones and the playback is abnormal; or, the speaker of the electronic device is damaged, and the audio data cannot be played abnormally, and so on. [0003] In the related art, in order to deal with the abnormal situation that the above-mentioned electronic equipment plays the audio data in the audio and video data, it is possible to carry out heresy playback to the audio and video that needs to be played by the electronic equipment: the video data as the video picture is...
