In contrast to audio and video, which are often transmitted unreliably, other media, such as slides, images and animations require reliability. Our approach transmits the data in two layers. One layer is for session-persistent data, with reliability achieved by FEC alone, using the Fcast protocol. The other layer is for dynamic data, with reliability achieved using the ECSRM protocol, which combines FEC with NACK suppression. Our approach is scalable to large heterogeneous receiver sets, and supports late-joining receivers. We have implemented our approach in a multicast version of PowerPoint, a graphical slide presentation tool. About the speaker: Jim Gemmell is a researcher in the Microsoft Research Telepresence Research Group - a part of the Bay Area Research Center (BARC) in San Francisco. He received his Ph.D. and B.Sc. from Simon Fraser University and his M. Math from University of Waterloo (all in computer science). His research interests include telepresence, telepresentations, digital audio and video storage/retrieval, and reliable multicast. He produced the on-line version of the ACM 97 conference.
