Abstract

The invention provides display equipment and a sound and picture synchronization control method. The display equipment and the sound and picture synchronization control method have the advantages thata callback function is registered for decoded multi-frame playing data and used for monitoring whether parameter configuration of a first frame of video data in the playing data is completed or not,the starting time of a system clock is delayed during execution of the parameter configuration, and the system clock is restarted until the parameter configuration of the first frame of video data iscompleted, thereby playing the video data and the audio data frame by frame according to the system clock, and realizing audio and video synchronization. According to the sound and picture synchronization control method, the system clock can be started after parameter configuration of the first frame of video data is completed, so that the problem of sound interruption caused by relatively long processing time of the first frame of video data and unstable output speed of the video data can be relieved.

Description

technical field [0001] The present application relates to the technical field of smart TVs, in particular to a display device and a method for synchronously controlling audio and video. Background technique [0002] Smart TV is a TV product based on Internet application technology, with an open operating system and chip, and an open application platform, which can realize two-way human-computer interaction, and integrates multiple functions such as audio-visual, entertainment, and data. Diverse and individual needs. Audio and video files can be played through the smart TV to form streaming media. In order to output better streaming media audio and video effects, smart TVs need to ensure multimedia audio and video synchronization. [0003] The multimedia synchronization function is to allow media data with the same time stamp (presentation timestamp, pts) in multiple streams to be played at the same time, that is, to achieve audio and video synchronization. For example, in...
