For progressive frame based video data it is possible to use more bit-energy for important bits of the frame to increase the probability that these bits are transfered correctly in a wireless link. With a progressive bit stream the usual bit error probability is less important than the position measure of the first error within the frame. Here we propose the use of two alternate metrics to dynamically fine tune the performance for a link with a low data rate feedback channel by changing the bit-energy distribution in the transmitted signal and thereby aid unequal error protection.
