Abstract
In a recent work, we proposed a method for
unequal error protection with Luby Transform codes and
showed that it achieves lower bit error rates than a state
of the art technique when the information symbols are
partitioned into two protection levels (most important and
least important). In this paper, we apply our previous
work to the problem of video multicast with heterogeneous
receivers. We provide simulations for the scalable video
coding (SVC) extension of the H.264/AVC standard and
show that our unequal error protection method provides
significantly better objective video quality results than two
state of the art techniques in applications where a high video
quality is desired.
