Problems solved by technology

[0009] The synchronization reference is specified when the playback is started, which is specified by the developer or the user interface. Although the user can specify it again during the playback process, after the designation, the player will passively use this synchronization reference, and the specified synchronization reference during the playback process. The synchronization reference may be unstable, or may not exist at all. At this time, the synchronization of each playback data cannot be realized, which may cause audio and video stuck, stuttering, jumping, etc.

Abstract

The invention discloses a method for synchronizing media play, belonging to the electronic technical field, which can acquire data of each synchronous reference of media play, takes a local system clock as reference to analyze the fluctuation of data of each synchronous reference, takes the synchronous reference corresponding to the data which has minimum fluctuation to implement synchronous operation of media play. The embodiment of the invention correspondingly provides media play equipment. The embodiment of the invention monitors the reliability of various synchronous references at real time, can identify the synchronous reference according to the actual condition of media play, and realizes dynamic regulation synchronous reference of media play, greatly eliminates the problems of audio / video pause and frame missing and the like brought by PTS and PCR, thus enabling the actual playing effect to achieve optimal smooth degree and improving the experience of users.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and device for synchronizing media playback. Background technique [0002] Media playback devices generally have the synchronization function of audio and video playback, that is, the picture and sound are played synchronously to provide users with a good viewing experience. Especially when playing news programs, lip synchronization is critical to the user experience. [0003] Currently, there are several synchronization methods for media playback devices: audio synchronization, program clock reference (PCR, Programe Clock Reference) synchronization, and video synchronization. The audio synchronization, that is, the video and subtitles follow the audio, are synchronized based on the audio playback time stamp (PTS, Play Time Stamp); the PCR synchronization, that is, a program clock reference provided by the program sending end, and the audio, video and subtitles are ...
