A comprehensive presentation of the video communication techniques
and systems, this book examines 4G wireless systems which are set
to revolutionise ubiquitous multimedia communication.4G Wireless
Video Communications covers the fundamental theory and looks at
systems’ descriptions with a focus on digital video. It
addresses the key topics associated with multimedia communication
on 4G networks, including advanced video coding standards, error
resilience and error concealment techniques, as well as advanced
content-analysis and adaptation techniques for video
communications, cross-layer design and optimization frameworks and
methods. It also provides a high-level overview of the digital
video compression standard MPEG-4 AVC/H.264 that is expected to
play a key role in 4G networks.
Material is presented logically allowing readers to turn
directly to specific points of interest. The first half of the book
covers fundamental theory and systems, while the second half moves
onto advanced techniques and applications. This book is a timely
reflection of the latest advances in video communications for 4G
wireless systems.
