ABSTRACT
Due to the increase in diversity of wireless devices, streaming media
systems must be capable of serving multiple types of users. Scalable
coding allows for adaptations without re-encoding. To account for
various viewing capabilities of each user, such as different spatial res-
olutions, multiple distortion measures are used [1]. In this paper, we
examine the question of how to broadcast media packets with multiple
distortion measures to multiple users. We cast the problem as a sto-
chastic shortest path problem and use Dynamic Programming to find
the optimal policy. We generate an offline algorithm to generate the
optimal transmission policy for the general case. We then show the op-
timal policy can be done online via a simple threshold policy for the
case of independent Bernoulli packet losses. Through experimental
