Abstract In this paper, we investigate successive refinement for the Wyner-Ziv source coding problem, in which the sources are considered to be vector Gaussian distributed and the side information has a degraded order. We fully characterize the rate-distortion region of this problem with covariance mean square error distortions. Toward this end, we use jointly Gaussian auxiliary random variables to give the achievability by evaluating the single-letter description of the rate region of Tian and Diggavi in 2007. For the converse part, we apply the information estimation relationship to prove our tight outer bound.
