Abstract

This article describes error resilience aspects of the video coding techniques that are standardized in the ISO MPEC-4 standard. It begins with a description of the general problems in robust wireless video transmission. The specific tools adopted into the ISO MPEG-4 standard to enable the communication of compressed video data over noisy wireless channels are presented in detail. These techniques include resynchronization strategies, data partitioning, reversible variable length codes (VLCs), and header extension codes. An overview of the evolving ISO MPEG-4 standard and its current status are described
