HEVC算法和体系结构：编码框架

这部分的具体分析在《HEVC算法和体系结构：环路滤波技术》中已有详细介绍。5、熵编码熵编码模块将编码控制数据、量化变换系数、帧内预测数据、运动数据、滤波器控制数据编码为二进制进行存储和传输。熵编码模块的输出数据即是原始视频压缩...

HEVC算法和体系结构：编码结构之编码完后码流的语法架构

编码结构之编码完后码流的语法架构本博文主要介绍HEVC编码结构，从编码完后码流的语法架构这一方面进行描述。在码流结构方面，HEVC采用了类似于H.264的分层结构，将属于GOP层、Slice层中共用的大部分语法游离出来，组成序列参数集SPS...

HEVC算法和体系结构：预测编码之帧内预测

这是由于H.264以固定大小的宏块为单元进行编码，在对当前块进行帧内预测时，其左下边方块很有可能尚未进行编码，无法用于参考，而HEVC的四叉树编码结构使得这一区域成为可用像素。2、帧内预测过程在HEVC中，35种预测模式是在PU的基础上...

HEVC算法和体系结构：预测编码之帧间预测

预测编码之帧间预测（Inter-Picture Prediction）帧间预测是指利用视频时间域相关性，使用临近已编码图像像素预测当前图像的像素，以达到有效去除视频时域冗余的目的。由于视频序列通常包括较强的时域相关性，因此预测残差值接近于0，将...
