Abstract

Application layer error resilience techniques in video communication are a relatively lightweight way of countering both isolated and burst error patterns. This paper systematically investigates their role. Flexible Macroblock Ordering (FMO) is shown to be an effective form of protection when errors are isolated but when burst errors are likely increasing the level of slicing is preferable. The paper considers which form of FMO produces the most gains in conjunction with error concealment. Video quality is shown to be content dependent, which may indicate a strategy for successful provision of conversational services for mobile devices.
