Abstract

Presently, both wireless communications and multimedia communications have experienced unequaled rapid growth and commercial success. Building on advances of network infrastructure, low-power integrated circuits, and powerful signal processing/compression algorithms, wireless multimedia services to support digital video applications such as videophone, video conferencing, video streaming, video on demand (VoD), and video surveillance, likely finds widespread acceptance. Many wireless multimedia applications require video coding schemes and underlying transport that can provide acceptable quality of service to the end users. Due to the burst errors nature of wireless channels and the error propagation property of compressed video, suitable source and channel coding schemes are required to handle such conditions. This chapter provides overview of video compression techniques, and the latest video coding standard, H.264/AVC, its implication for the wireless video transmission, and our research contribution on joint source-channel coding for wireless video transmission.
