Actually, CD uses a form of the Reed Solomon code. Though the Hamming

Not sure of all the details, but yes IIRC it is a form of cross interleaved
RS code. I think this is a 'block' code equivalent to a hamming code.

I haven't done this in a while, but IIRC the Reed Solomon code is a type of BCH
code, which itself is a cyclic code.


However the channel bit stream is encoded on a number of levels between the
sample data and the disc.


did you mean 'cross interleaved code' when you said 'encoded on a number of
levels between the sample data and the disc'?
