Video technology continues to advance since the publication, in early 2003, of the first edition of this book. Further “convergence” – Jim Blinn might say collision – between video and computer graphics has occurred. Television is losing; computing and internet transport are winning. Even the acronym“TV” is questionable today: Owing to its usage over the last half century, TV implies broadcast, but much of today’s video – from the Apple iTunes store, Hulu, NetFlix, YouTube – is not broadcast in the conventional sense. In this edition, I have replaced SDTV with SD and HDTV with HD.
