Enhanced prioritization for video streaming over wireless home networks with IEEE 802.11e

Abstract: Cyclic intra refresh is able to mitigate temporal error propagation. This paper exploits the unequal error sensitivity introduced within individual video frames when using a cyclic intra refresh line of macroblocks. Slice-level priority is proposed based on the relative position of a slice with respect to the intrarefresh line. Two in-frame prioritization schemes are investigated: a region-based priority assignment and a packet-based priority assignment. The region-based scheme assigns packet priorities in the… Show more

“…However, the work in [11] made no contribution to the issue of prioritization. In fact, both the other two schemes [9,10] differed from the present proposal because prioritization of slices was determined by the position of the cyclic intracoded line within each video frame rather than through distortion analysis.…”

“…In [9], the line split the frame into three unequal regions and a scheme was presented that ensured the regions' areas were properly assigned to slices. Then in [10], regions were allowed to wrap around a frame's boundaries so that region sizes could be equalized. The latter scheme was found to be preferable to a simple geometrical division.…”
