Abstract :
A general necessary condition is established for the lossy source broadcast problem and is further leveraged to derive an outer bound on the admissible source region for broadcast channels with correlated sources. It is shown that the new outer bound is strictly tighter than the existing one by Gohari and Anantharam.
