ABSTRACT
The heterogeneity of the Internet's transmission resources
and end system capability makes it difficult to agree on ac­
ceptable traffic characteristics among the multiple receivers
of a multicast video stream. Three basic approaches have
been proposed to deal with this problem: 1) multicasting of
replicated video streams at different rates, 2) multicasting
the video encoded in cumulative layers, and 3) multicasting
the video encoded in non­cumulative layers. Even though
there is a common belief that the layering approach is bet­
ter than the replicated stream approach, there has been no
studies that compare these schemes. This paper is devoted
to such a systematic comparison. Our starting point is an
