| 摘 要： | 视频和音频是流媒体传输的主要数据,各个媒体流在时间上彼此关联,互相约束.针对多媒体业务传输中出现的音视频不同步问题,提出一种将RTP时间戳映射到RTCP绝对时间NTP轴的方法,建立音视频之间的同步点和同步检测判决准则.通过仿真实验,该算法能够实现音视频的基本同步.

| Abstract: | Video and audio is the main data stream media transmission, All media streams are related to each other in time. For multimedia services transmission of audio and video sync problem, Make an absolute time to map RTP timestamps to RTCP NTP axis methods, establis- hing synchronization and synchronization between audio and video detection of sentencing guidelines. Through simulation, the algorithm is a- ble to achieve synchronization of audio and video. |
