| Abstract: | This paper presents an overview 1] of the MPEG-4 (Motion Picture Experts Group) coded video file structure and the VOP (Video Object Plane) types followed by classification of errors and introduction of the NEWPRED mechanism in MPEG-4 for error concealment. An UEP (Unequal Error Protection) scheme is described with a discussion on how the proposed scheme affects the UMTS (Universal Mobile Telecommunications System) network efficiency.
