Hello,

Assuming that I have a very sparse data-stream (16 bit/sample) which contains 80% zeros.

I know that in the worst case i'll need 2*20%=40% to transfer the non-zero data along with their indices. But this seems stupid, isn't it?

do you know if there is any standard coding scheme for compression of such data stream. I suppose there should a more efficient standard methods...

thanks a lot

But RLE seems to be useful when all your data contains repetitive patterns. Otherwise it could impose more data load... other than trains of zeros that I have, sometimes I have series like 4 0 -6 0 0 185 0 -28 0 0 277....
you see zeros are more but they are not necessarily together...
