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.
In order for wireless devices to function, the signals must be coded in standard ways so that the sender and the receiver can communicate. This area of video source coding is one of the key challenges in the worldwide push to deliver full video communications over wireless devices. This important new book reviews current progress in this field and looks at how to solve some of the most important technology issues in the months and years ahead.
The vision of being able to communicate from anywhere, at any time, and with any type of information is on its way to becoming reality. This natural convergence of mobile communications and multimedia is a field that is expected to achieve unprecedented growth and commercial success. Current wireless communication devices support a number of basic multimedia services (voice, messages, basic internet access), but have coding problems that need to be solved before "real-time" mobile video communication can be achieved.
