The Setting Strategy of Multi-source Streaming Media Buffer Size Based on Grouping

多媒体系统必须能够限制时延抖动的变化,通过在播放端设置缓冲区以抵消时延抖动,从而保证媒体内及媒体间的同步。根据多源流媒体的分发特点,文章设计了一种分组的媒体缓冲区大小的设置方案,该方案在保证流媒体同步的基础上,巧妙地解决了流媒体不同码率的缓冲区大小设置问题。

In streaming media systems end-to-end delay jitter often leads to the discontinuity of information playback. According to the distributing character of multi-source streaming media, a setting strategy of multi-source streaming media buffer size based on grouping is proposed. This strategy not only guarantees the streaming media synchronization, but also ingeniously sloves the setting problem of buffer size, especially for the media programs of different code rates.
