Applications that are in the process of becoming essential to users include video telephony gaming or TV broadcasting. This trend creates great opportunities for identifying new wireless multimedia applications and for developing advanced systems and algorithms to support these applications. Given the nature of the channel and of the mobile devices topics such as scalable multimedia coding error resilience and energy-efficient operation are of great importance. The papers in this issue focus on state-of-the-art research on several aspects of wireless multimedia communications. The first paper of R. Razavi et al. proposes an adaptive modulation scheme to support higher-quality video streams for Bluetooth-enhanced data rate wireless channel. The scheme is based on 1 the content type at the
