Embodiment Construction

[0108] In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0109] refer to figure 1 , shows an example flow diagram of a display terminal synchronously playing video data and audio data.

[0110] Such as figure 1 As shown, the audio and video data reading module in the display terminal reads multimedia data, and then decodes to obtain video data and audio data, and the video data and audio data have time stamps for synchronization.

[0111] Then the video data is sent to the video output module, and the audio data is sent to the audio output module. When playing multimedia data, the time stamp synchronization of video data and audio data is performed by the playback time point control module, and then the video output module plays the vid...

Abstract

The embodiment of the invention provides a video data and audio data synchronized playing method and device and equipment. The method includes the steps that multimedia data are received on a display terminal side; the multimedia data comprise video data and audio data; the video data carry one or more video timestamps; the audio data are sent to a mobile device side; the display terminal side is connected with the mobile device side in a wireless transmission mode; when the video data are played, playing object timestamps are generated according to currently-played video timestamps; the playing object timestamps are sent to the mobile device side; the mobile device side is used for playing the audio data corresponding to the playing object timestamps. With the video data and audio data synchronized playing method and device and the equipment, the constraint caused when wired earphones are directly connected with a display terminal can be gotten rid of by a user, operation of the user is facilitated, and synchronized playing of the audio data and the video data is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of multimedia data processing, in particular to a method for synchronously playing video data and audio data, an apparatus for synchronously playing video data and audio data, and a device. Background technique [0002] With the popularization of players that can support various media, more and more media files are played synchronously to obtain better appreciation and artistic effects. Among them, playing videos, enjoying music, and browsing pictures are the most widely used media execution. [0003] Taking a smart TV device as an example, the smart TV includes a smart TV and a smart set-top box, which can play multimedia data. In situations such as when the family is resting at night, in order to avoid disturbing others and ensure viewing of multimedia data, the user may wish to listen to the sound of the video played by the smart TV device by wearing headphones instead of the speake...
