Abstract

With all the hype created around multimedia in the last few years, consumers expect to be able to access multimedia content in a real-time manner, anywhere and anytime. One of the problems with the real-time requirement is that transportation networks, such as the Internet, are still prone to errors. Due to real-time constraints, retransmission of lost data is, more often than not, not an option. Therefore, the study of error resilience and error concealment techniques is of the utmost importance since it can seriously limit the impact of a transmission error. In this paper an evaluation of a part of flexible macroblock ordering, one of the new error resilience techniques in H.264/AVC, is made by analyzing its costs and gains in an error-prone environment. This paper concentrates on the study of flexible macroblock ordering (FMO). More specifically a study of scattered slices, FMO type 1, is made. Our analysis shows that FMO type 1 is a good tool to introduce error robustness into an H.264/AVC bitstream as long as the QP is higher than 30. When the QP of the bitstream is below 30, the cost of FMO type 1 becomes a serious burden.
