Query: Excellent Book on MPEG-4

For readers requiring to jumpstart their knowledge in MPEG-4, this is an excellent book to buy. The text is very well written and is extremely readable. The authors provide a lot of insights into the technology and its use. The only problem I had in reading the book was incorrect units for the numbers in some of the tables. It is fairly easy for the reader to detect and correct these. Hopefully the authors will take care of that in future editions.
