substreams中文什么意思

例句与用法

1. the lagrange multiplier method using rate and distortion information is then applied to optimal allocates bitrate for each frame in fine granular scalability substreams
   基于拉格朗日乘子法的最优化码率分配算法可以利用该模型中的率失真信息分配码率,在码率一定的条件下提供最好的视频效果。
2. 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。
3. a file format is proposed based on the generic model and iso base media file format . we first create a directed acyclic graph model to describe the substreams and relationships among those substreams in a scalable video stream
   本文首先建立了一个有向无环图模型,该模型能够描述可扩展视频编码码流中各子码流和子码流间复杂的依赖关系。
4. a file format is proposed based on the generic model and iso base media file format . we first create a directed acyclic graph model to describe the substreams and relationships among those substreams in a scalable video stream
   本文首先建立了一个有向无环图模型,该模型能够描述可扩展视频编码码流中各子码流和子码流间复杂的依赖关系。
5. in this paper, a gray video md-3d-spiht algorithm is proposed, which extends the md-spiht algorithm into 3d-spiht . this method is to divide the 3-d wavelet coefficients into some number p of different groups according to their spatial and temporal relationships, and then to encode each group independently using 3d-spiht algorithm, so that p independent embedded 3d-spiht substreams are created . multiple descriptions are created
   2、将md-spiht方法推广应用于视频序列,提出了灰度视频md-3d-spiht算法,该算法先对一组视频图象进行多级离散三维小波变换,在小波域建立空间方向树,及对空间方向树分组,再分别对各组进行3d-spiht编码,即产生多个描述,且每一描述的码流是完全嵌入式的,易于实现质量可分级编码。
