Using Powerful FEC Codes for File and Streaming Delivery to Mobile Receivers


Date Thursday September 2nd 2004
Time 4:00-5:00pm
Venue George E. Pake Auditorium

PARC Forum

We describe Raptor codes, the most flexible and powerful FEC codes available for delivery of data over packet-based networks. We demonstrate that Raptor codes are crucial for both efficient delivery of files and for high-quality video streaming over emerging broadcast and multicast wireless networks. Example applications include delivery of navigational updates and point-of-interest data to automobiles and delivery of multimedia files and H.263 streaming video to 3G telephones and PDAs. Standardization of the general approach of using FEC codes for file and streaming delivery within the IETF and 3GPP will also be outlined.


Dr. Michael Luby cofounded Digital Fountain, Inc. in 1998, where he currently holds the position of Chief Technology Officer. Michael is a world-renowned Theoretical Computer Scientist, and has made breakthrough research contributions in the areas of coding theory, randomized algorithm design and analysis, transport protocols and cryptography. He is actively leading the development of several transport standards within the Internet Engineering Task Force (IETF). After receiving his Ph.D. in Theoretical Computer Science from UC Berkeley in 1983 he was a Professor in Computer Science at the University of Toronto. In 1988 Michael joined the International Computer Science Institute in Berkeley to become the Leader of the Theory Group and concurrently an Adjunct Professor at UC Berkeley. Michael is a recipient of the 2002 Information Theory Society Paper Award for some of his coding theory research and the 2003 SIAM Outstanding Paper Prize for some of his cryptography research.
