Embodiment Construction

[0036] In order to make the above purpose, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] refer to figure 1 , shows a schematic diagram of a principle of playing audio and video data. Such as figure 1 As shown, after video-on-demand, the audio-video data reading module in the display terminal reads multimedia data, that is, audio-video data, and then decodes it to obtain compressed video data and audio data. The audio and video decompression module decompresses the compressed video data and audio data, and then sends the decompressed video data to the video output module, and sends the decompressed audio data to the audio output module. The audio and video data of the on-demand video file are sent to the audio output module and the audio display module in units of frames, and each fr...

Abstract

The invention provides a playing method of audio data and video data, a smart television set and mobile equipment. The method includes the steps that an audio and video file is received by a display terminal; the video data and the compressed audio data are read from the audio and video file; the compressed audio data are sent to the mobile equipment, wherein the compressed audio data are used for being decompressed and played on the mobile equipment; the video data are played. By means of the playing method of the audio data and the video data, the smart television set and the mobile equipment, delay between the audio data and the video data is avoided, and synchronization performance of the audio data and the video data is improved.

Description

technical field [0001] The present application relates to the technical field of audio and video playback, in particular to a method for playing audio and video data, smart TVs and mobile devices.
