Embodiment Construction

[0108] In order to make the above objectives, features, and advantages of the embodiments of the present invention more obvious and understandable, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementations.

[0109] Reference figure 1 , Shows an example diagram of the process of synchronously playing video data and audio data on a display terminal.

[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 a time stamp 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 playback time control module synchronizes the time stamps of the video data and audio data, and then the video output module plays the video da...

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; playing object timestamps returned by the mobile device side are received; the playing object timestamps are timestamps generated according to currently-played audio timestamps when the audio data are played by the mobile device side; the video data corresponding to the playing object timestamps are played on the display terminal side. 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] The embodiment of the present invention relates to the technical field of multimedia data processing, in particular to a method for synchronously playing video data and audio data, a device for synchronously playing video data and audio data, and a device. Background technique [0002] With the popularity of players that can support various media, more and more media files are played simultaneously to obtain better appreciation and artistic effects. Among them, playing videos, enjoying music, and browsing pictures are the most widely used Media execution method. [0003] Taking smart TV equipment as an example, smart TVs include smart TVs and smart set-top boxes, which can play multimedia data. In situations such as family rest at night, in order to avoid disturbing other people and ensure the viewing of multimedia data, users may wish to listen to the sound of the smart TV device playing video by wearing headphones to replace the speaker device of the smart...
