The Makeover from DVD to Blu-Ray Disc
Praise for Blu-ray Disc Demystified “BD Demystified is an essential reference for designers and developers building with- in Blu-ray’s unique framework and provides them with the knowledge to deliver a compelling user experience with seamlessly integrated multimedia.” — Lee Evans, Ambient Digital Media, Inc., Marina del Rey, CA “Jim’s Demystified books are the definitive resource for anyone wishing to learn about optical media technologies.” — Bram Wessel, CTO and Co-Founder, Metabeam Corporation “As he did with such clarity for DVD, Jim Taylor (along with his team of experts) again lights the way for both professionals and consumers, pointing out the sights, warning us of the obstacles and giving us the lay of the land on our journey to a new high-definition disc format.” — Van Ling, Blu-ray/DVD Producer, Los Angeles, CA “Blu-ray Disc Demystified is an excellent reference for those at all levels of BD pro- duction. Everyone from novices to veterans will find useful information contained within. The authors have done a great job making difficult subjects like AACS encryption, BD-Java, and authoring for Blu-ray easy to understand.” — Jess Bowers, Director, Technical Services, 1K Studios, Burbank, CA “Like its red-laser predecessor, Blu-ray Disc Demystified will immediately take its rightful place as the definitive reference book on producing BD. No authoring house should undertake a Blu-ray project without this book on the author’s desk. If you are new to Blu-ray, this book will save you time, money, and heartache as it guides the DVD author through the new spec and production details of producing for Blu-ray.” — Denny Breitenfeld, CTO, NetBlender, Inc., Alexandria, VA “An all in one encyclopedia of all things BD.” — Robert Gekchyan, Lead Programmer/BD Technical Manager Technicolor Creative Services, Burbank, CA About the Authors Jim Taylor is chief technologist and general manager of the Advanced Technology Group at Sonic Solutions, the leading developer of BD, DVD, and CD creation software.
