rate control scheme for base layer in scalable video coding 基于可分级编码基本层的码率控制方法
so scalable video coding ( svc ) is presented . recently, it has been researched intensively and has got noteworthy achievement 于是可伸缩性视频编码(svc)便应运而生,并且成为近几年视频编码领域的研究热点,取得了显著的研究成果。
this thesis has focused on the key technologies of video transmission system, including fine granular scalable video coding, congestion control and error control technology 然而,由于视频的信息量大,且internet又是尽力型网络,因此internet上的视频通信也是一个研究难点。
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。
due to its multiresolution, time / frequency localization and lower time complexity, wavelet is suitable for scalable video coding, which has been applied to coding algorithms such as ezw, spiht and ebcot 随着用于图像压缩的ezw、spiht和ebcot模型及用于视频压缩的3d-ezw、3d-spiht和3d-escot模型的出现,基于小波变换的嵌入编码已成为图像视频压缩研究的主流。
