Cross Layer Design for Video Communications: Cross Layer Bandwidth Allocation and Delay Allocation for Video Transmission over Wireless Internet

Over the past decades, a tremendous effort has been put into the research to develop advanced system for video communications over wireless and Internet channels. Because video communications are essentially delay-sensitive, bandwidth-intense and loss-tolerant, joint source-channel coding (JSCC) is investigated intensively to attain the optimum performance. The advances achieved in cross-layer design at the lower layers (PHY and DLL) can be further enhanced by taking into account source characteristics and requirements allowing existing networks to provide optimal time-varying Quality of Service (QoS). This book proposes both coding schemes and system design strategies for video wireless communications. The analysis should be especially useful to professionals in video coding and wireless communications fields, both in academia and in industry.
