decompressCtu函数用来对coding_tree_unit函数解码得到的数据进行解析,根据解码得到的运动参数恢复ctu的像素信息,即重建像素reco信息。 入口参数cs是picture的cs,其中包括了一帧内所有ctu的所有信息,ctuArea即需要decompress的ctu区域。 获取ctu区域内的所有cu,判断这些cu的预测模式是intra还是inter,然后分别进行帧内和帧间...

Examples include a device for coding video data, the device including a memory configured to store video data, and one or more processors configured to obtain adaptive loop filtering (ALF) information for a current coding tree unit (CTU) from one or more of: (i) one or more spatial ...
coding tree unitThe High Efficiency Video Coding standard increases in the range of [30, 40] % data compression ratio compared to H.264/MPEG-4 (AVC), but it requires bigger number of operations. HEVC uses a quadtree coding structure. The quadtree partitioning process is a high complexity ...
Method based on coding tree unit level rate-distortion optimization for rate control in video codingA method based on CTU level rate-distortion optimization for rate control in video coding which can effectively improve the perceptual rate-distortion performance and coding efficiency is provided. ...

Received video data with encoding tree unit size. By setting two or more flags, the size of encoding tree units associated with video data is identified. Encode/decode video data based on flags corresponding to the size of signal encoding tree units....
In an example, a kind of method of encoded video data may include selection, it can be used as during entropy coding, the one or more adjacent C Us of context syntactic element and current unit (CU) based on the related information of CU depth are relative to current CU. Syntactic ...
Coding tree unitSynthesized viewsComplexityThe scalable extension of the high efficiency video coding standard (SHVC) combines the large compression efficiency and high visual quality of HEVC, with the possibility of encoding different versions of the same video in a single bitstream. However, this ...
A hardware encoder has a bit estimation block to compute an estimated bit size for a Coding Tree Unit (CTU). A CTU bit size limit manager selects quantization parameters for use in quantization. The quantization parameters are selected based upon the estimated bit size to insure that the CTU...
