    Abstract

    Multimedia applications such as video conference, digital video broadcasting (DVB), and streaming video and audio have been gaining popularity during the last years, growing also among mobile users. Quality of Service requirements for multimedia over wireless raises huge challenges not only concerning the physical bandwidth, but also the network design and services. This has to be addressed by future 4G systems. To this end, joint source and channel coding (JSCC) has provided promising results; however, the proposed mechanisms typically do not provide IP network support. In this paper we present an architecture for JSCC systems designed for an IP network with end-to-end overall optimisation. All necessary mechanisms for transmitting the joint optimisation control information over wired and wireless network using cross-layer design are also described. Finally, partial simulation results obtained with this system design and H.264/AVC video input are presented.
