摘要

The wide deployment of wireless networks along with rapidly growing popularity of mobile devices (such as smart phones and portable thin-client devices) in the last decade has enabled Ubiquitous Multimedia Computing (UMC). UMC opens up a whole range of interesting and attractive applications, such as watching movies in vehicles, reading electronic magazines in parks and capturing videos to the internet in outdoor education. UMC consists of three layers in terms of both software and hardware: systems, networking and applications. The system layer is responsible for providing the common functions required by all UMC applications, such as mixing/de-mixing of audio/video streams; storage, retrieval, and exchange of multimedia data; management of distributed context acquired from environments and mobility management across heterogeneous networks.
