Software architecture and media processing considerations

Abstract

This paper presents a mobile multimedia applications perspective of a wireless ATM network (WATMnet) which has been developed first as a proof-of concept prototype, and is now in the process of migration to real-world$eld trials. The WATMnet system provides mobile terminals (such as laptop PC's and PDA's) the ability to communicate via quality-of service (QoS) based ATM virtual circuits at bitrates up to 25 Mbps. We focus on media processing and software techniques used by mobile multimedia terminals in this wireless networking environment forQoS adaptation and media scaling support. Some recent experimental results are presented.
