Abstract :
It is shown that the rate-distortion bound 
remains true when 
in the definition of mutual information is replaced by an arbitrary concave 
nonincreasing function satisfying some technical conditions. Examples are given showing that for certain choices of the concave functions, the bounds obtained are better than the classical rate-distortion bounds.
