Abstract :
It is shown that the mixture of two codes of block length 
can have a distortion strictly less than the distortion of the best possible code of block length having the same rate. The seeming contradiction is explained by offering two interpretations for the mixture of two codes and then explaining why the bound for the performance of the best code cannot be applied directly to the mixture.
