By directed acyclic graph model , video server can select correct substreams by network bandwidth and terminal capability to get any frame rate , spatial resolution but coarse granular scalability presentation of video 通过该模型,视频流媒体服务器能够根据网络带宽,终端能力,正确地选择子码流进行传输播放。
Aimed at the weakness encountered in the dynamic performance analysis tools of parallel programming , a new intermittent approach is provided for performance analyzing of coarse granular parallel programs 摘要针对?行程序的动态性能分析方法存在的问题,提出了一种大粒度?行程序的新的性能分析方法,即间歇性性能分析方法。
