Abstract

The successive refinement of information (or source divisibility) under error exponent or reliability constraint is discussed. By rehabilitating Maroutian's result on multiple descriptions [13], we refine our previous proof on successive refinability conditions reported in [7] and restate the result by Tuncel and Rose [17]. In particular, it is noted that the successive refinement in “purely” reliability sense is always possible.
