The original idea for a book stemmed from a meeting with Jennifer Welham of Focal Press at a papers session during an annual conference of the National Association of Broadcasters. I would like to thank Philip O’Ferrall for suggesting streaming media as a good subject for a book; we were building an ASP to provide streaming facilities. I received great assistance from Colin Birch at Tyrell Corporation, and would like to thank Joe Apted at ClipStream (a VTR company) for the views of an encoding shop manager. I am especially grateful to Gavin Starks for his assistance and for reading through my draft copy.
The web sites of RealNetworks, Microsoft, and Apple have provided much background reading on the three main architectures.
