Heresy audio and video playback method, device and audio and video playback system

Abstract

Embodiments of the present invention provide a heretical audio and video playback method, device, and audio and video playback system. Among them, a heterogeneous audio and video playback method is applied to the first device to obtain audio and video data; using the first communication protocol, the audio data and delay detection data are sent to the second device at the same time, so that the second device receives After receiving the audio data and the delay detection data, return the delay response data, and buffer the audio data, and play the audio data after the preset buffer duration; receive and based on the delay response data, obtain the second device to play the audio data The playback delay; the delay response data includes: feedback data corresponding to the delay detection data, and a preset cache duration; after the playback delay, the video data is played. This solution can achieve the effect of synchronizing audio and video when playing heresy audio and video.

Description

Technical field [0001] The present invention relates to audio and video technologies, and more particularly to a method for playing audio and video heresy, audio and video playback apparatus and system. Background technique [0002] When using an electronic device to play audio and video data, there may be cases of abnormal electronic devices to play audio data audio and video data. For example, the need to use headphones audio data, the electronic device can not connect headphones abnormal playback; or damage to the speaker of the electronic device, the audio data can not be played like playing abnormality. [0003] In the related art, in response to the electronic device for playing audio data in audio and video data are abnormal, can only be performed by the electronic device to play the audio and video playback heresy: the electronic device displays the video data as the video picture, which is different from the electronic device and another electronic device can play the no...

Problems solved by technology

[0004] However, when playing video, it is necessary to ensure that the picture and sound of the video are synchronized, and the electronic device in the above-mentioned heterodox play is different from the other device, which may easily cause the video picture played by the electronic device to be different from the sound of the video played by another electronic device. out of sync problem
