Video and audio are becoming increasingly popular on the Internet and are being accessed by a variety of networked devices through either wired or wireless links. Many distributed multimedia applications have been created, including Internet telephony, Internet videoconferencing, on-demand streaming or broadcasting, IPTV, multimedia messaging, distance learning, gaming and entertainment, and so forth. Streaming real-time and on-demand audio and video over the Internet, local and wide area wireless networks are becoming a mainstream means of communication. To accelerate the adoption of these new emerging applications, various issues must be addressed such as the architecture and design of multimedia communication systems, the quality-of-service (QoS) provisioning, the network and content security, etc.
