摘要
A method and apparatus are described for constructing efficient Slepian-Wolf codes for inputs that do not have uniform probability distributions, and for channels which are not symmetric. Whereas conventional Wyner-Ziv video compression systems assume symmetrical probability distributions and ignore the marginal distribution component, the invention incorporates the marginal distribution component by combining the marginal distribution and conditional distributions as input to a transform that generates a symmetrical output, which is then fed into the conventional density evolution method.
