采用vb开发的监控类代码，可以使用该代码对海康卡传输过来的码流进行截图的功能。-used vb development of the control category code The code can be used for transmission over Haikangka Bitstream screenshots for the function.

LZW的压缩算法，比较简单，只能实现对输入字符串的实现码流-LZW compression algorithm is relatively simple, can only be realized on the importation string achieve bitstream

BCS-SPL-DPCM将DPCM和均匀标量量化应用于BCS-SPL，以从BCS测量产生压缩比特流。(BCS-SPL-DPCM applies DPCM and uniform scalar quantization to BCS-SPL to produce a compressed bitstream from the BCS measurements.)
