Résumé
This book concentrates on three main challenges of video
coding for mobile communications: higher coding efficiency,
reduced computational complexity, and improved error
resilience. Unlike other high level books and articles that
focus on individual aspects in this field, this book has
been designed as a quick, easy, and practical introduction
to all of the fundamentals and standards of video source
coding. will be of particular interest to the thousands of
engineers and computer scientists who are working to link
our global economy through mobile multimedia
communications.
