Raptor coding technology

Over the past 10+ years Digital Fountain (now part of Qualcomm) has invented, developed, standardized and deployed fountain coding technologies. Raptor codes, for example as specified in IETF RFC 5053, are the most well-known and used of these technologies, as they are the foundation of a number of data transport paradigms used to support higher level services such as broadcast file delivery and video streaming. In this talk I will overview many of the theoretical and practical ideas that have been integrated into the design of Raptor codes over the years, including RaptorQ codes which are the newest and most advanced generation of Raptor codes.
