解 释: 一种新型的脉冲编码技术，它是利用自适应技术和差值编码技术相结合的一种编解码技术。可以使64 kbit/s的脉冲编码(PCM)信号进一步压缩为32 kbit/s的脉冲编码数据。使传输脉冲编码所需要的带宽减少一半，提高了信道的利用效率，并且还可以使脉码调制 ...

This paper presents the Adaptive Differential Pulse Code Modulation (ADPCM) method of digitally storing and reproducing speech or other waveforms. A detailed explanation of the encoding steps is given ...

Hi everybody,<BR><BR> Just for fun, I've decided to try writing my own lossless image compressor. Its nothing special, just differential pulse code modulation with rice coding and a huffman encoder ...
