Enhanced slicing for robust video transmission

This paper presents a low complexity yet effective slicing scheme for enhanced error resiliency. The proposed scheme uses Flexible Macroblock Ordering (FMO) with no decoder modifications and without introducing any increase in bitrate or computational complexity. Frame level packet priority is then provided based on slice position within the frame. Experimental results indicate that, when FMO is combined with Unequal Error Protection, the scheme can achieve quality gains up to 4 dB over other slicing techniques.
