PAV (H265) 是 音视频 压缩解压 协议,非常不同于H264/MPEG4,ZPAV (H265) 的基本算法 是 小波,多级树集合群,广义小波,数学形态小波,......
ZPAV (H265) 基本算法 :
1,图象与声音分解与合成 :小波 ;
2,图象与声音前处理 :小波子带零交叉降噪,目标纹理处理,语音处理 ;
3,速率控制 :小波子带熵速率控制 ;
4,量化与反量化 :小波子带熵量化与反量化 ;
5,低频分量和高频分量的降维 :小波子带邻域交叉降维 ;
6,运动矢量和量化表的分解与合成 :广义小波 ;
7,位面编码 :数学形态小波,多级树集合群,嵌入零树,位面降维 ;
8,位流编码 :算术编码,熵编码 ;

B,图象与声音后处理 :低通滤波,断点重构,宏块平滑 ;
C,误码纠错 :矢量仿真,帧间仿真 。
(The PAV (H265) is the audio and video compression and decompression protocol, is very different from H264/MPEG4
ZPAV (H265) algorithm is a wavelet, multi-level tree collection group, and generalized wavelets, mathematical morphology, wavelet, ...
ZPAV (H265) algorithm:
1, image and sound decomposition and synthesis: wavelet
2, image and sound processing: wavelet sub-band zero-crossing noise, target texture processing, speech processing
3, the rate control: wavelet subband entropy rate control
4, quantization and inverse quantization: Wavelet subband entropy quantization and inverse quantization
5, the dimensionality reduction of the low frequency component and high frequency components: the wavelet subbands neighborhood cross-dimensionality reduction
6, the decomposition and synthesis of the motion vector and quantization tables: generalized wavelet
7, bit-plane coding: the mathematical form of wavelet multi-level tree collection group, embedded zerotree, bit plane)

GZIP解压例子
利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)

HuffMan
哈夫曼编码译码系统,设置发送者和接受者两个功能,
发送者的功能包括:
①输入待传送的字符信息;
②统计字符信息中出现的字符种类数和各字符出现的次数(频率);
②根据字符的种类数和各自出现的次数建立哈夫曼树;
③利用以上哈夫曼树求出各字符的哈夫曼编码;
④将字符信息转换成对应的编码信息进行传送。
接受者的功能包括:
①接收发送者传送来的编码信息;
②利用上述哈夫曼树对编码信息进行翻译,即将编码信息还原成发送前的字符信息。
(Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)
