....reduced quality due to the resulting congestion. A uniform transmission rate fails to accommodate the bandwidth heterogeneity of this diverse set of receivers. An often cited approach for coping with receiver heterogeneity in real time multimedia transmissions is the use of layered media streams [2, 3, 4, 5, 6, 7, 8, 9]. In this model, rather than distribute a single level of quality using a single network channel, the source distributes multiple levels of quality simultaneously across multiple network channels. In turn, each receiver individually adapts its reception rate by adjusting the number of layers that ....

....: and each decoder module D is capable of decoding any cumulative set of bit strings. Each additional string produces an improvement in reconstruction quality. By combining this approach of layered source coding with a layered transmission system, we can solve the multicast heterogeneity problem [3, 5, 6, 8]. In this architecture, the multicast source produces a layered stream where each layer is transmitted on a different network channel, as illustrated in Figure 3 for the case of the UCB seminar. In turn, the network forwards only the number of layers that each physical link can support. For ....
