Advances in video coding technology and increases of available processing power have enabled video applications on mobile devices. While the current generation of codecs, including the emerging H.264/MPEG-4 AVC standard, provide increased coding efficiency, further advances are desirable due to limited radio resources in mobile networks. Future codecs should address the needs of mobile media applications including video conferencing, video streaming, video broadcasting, and multimedia messaging. Future wireless networks are expected to be packet-based, and packetization of video data should be designed accordingly. Entropy coding, spatial and temporal prediction, transforms, and quantization are the key elements of a video codec. Improvement of these components and their interactions will lead to more efficient codecs. Furthermore perceptual quality remains poorly understood. A better understanding will improve encoding as well as pre- and post-processing algorithms.
