Abstract

The invention discloses a data output method and related equipment. The method is applied to host equipment included in a video playing system. The video playing system further comprises an audio playing device and a sub-machine device comprising a display screen. The method comprises the following steps: timestamps are marked on the video stream data frame and the audio stream data frame by the host equipment; then, the video stream data frame with the time stamp is sent to the sub-machine equipment, and the audio stream data frame with the time stamp is sent to the audio playing equipment; and then the sub-machine equipment feeds back a delay time length to the host equipment when extracting the data in the video stream data frame, the audio playing equipment feeds back a delay time length to the host equipment when extracting the data in the audio stream data frame, and finally, the host equipment adjusts the output time of the audio data and the video data based on the two delay time lengths. By adopting the embodiment of the invention, the synchronous playing probability of the audio data and the video data can be improved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a data output method and related equipment. Background technique [0002] At present, mobile phones have become an indispensable part of people's lives. People can use mobile phones to play video, play audio, etc. When playing a video, if you use an external audio playback device (such as a Bluetooth headset, Bluetooth speaker, etc.) to play audio, or due to the layout of the phone, the audio playback device (such as a loudspeaker, etc.) And / or there is a certain distance between the display of the mobile phone and the processor of the mobile phone, and there may be a problem that audio data and video data are played out of sync. Contents of the invention [0003] Embodiments of the present application provide a data output method and related equipment, which are used to increase the probability of synchronous playback of audio data and video data. [0004] In ...
