Synchronization process for mobile phone stream media audio and video

Abstract

The invention discloses a synchronization method of a mobile phone streaming media audio and video, comprising the steps as follows: the received audio and video data packet is registered into the buffer area of a mobile phone terminal to carry out framing and sorting; when the audio data packet is decoded by a decoder, the difference value between system time when the audio data packet is sent to the decoder and time stamp of the audio frame of the audio data packet is recorded to be taken as a reference time offset value; the decoding and sending display time of the video data packet can be determined according to the reference offset value, so as to realize the synchronous playing. As the synchronization proposal before the audio and video decoding is adopted, more particularly, the reference time offset value is corrected by the audio and video decoding time compensation time, the time offset of the audio and video data flow caused by the equipment in the process before the transmission and decoding is effectively solved, the restriction that the decoded audio and video data flow can not be operated by certain techniques of the current mobile phone terminals and the used decoder is broken down, and the synchronous playing of the audio and video of the mobile phone is excellently realized.

Description

technical field [0001] The invention relates to a mobile phone streaming media technology, in particular to an improved audio and video synchronization method for mobile phone streaming media. Background technique [0002] In recent years, with the development of computer technology, compression technology and Internet network technology, streaming media services in wireless networks have also been rapidly developed and applied. The so-called streaming media simply refers to multimedia data (audio, video, animation or other multimedia files) transmitted over the network using streaming technology. An acute problem of multimedia data transmission is the unpredictable data arrival time. [0003] However, the transmission of streaming media requires the timely arrival of data for playback and playback, and streaming technology is to upload continuous video and audio information to the website server after compression processing, allowing users to watch and listen while downloa...

AI Technical Summary

Problems solved by technology

However, due to some technical limitations of the mobile terminal, sometimes the decoding chip used cannot provide the operation of the decoded data, and it is impossible to implement an ideal synchronization scheme for the decoded audio and video data

[0008] Therefore, prior art still needs to improve and develop
