Zusammenfassung
The pervasive computing environment and the wide
network bandwidth provide users more opportunities to utilize
remote computing resources. In this paper, we introduce a highperformance
remote computing platform to enable thin clients to
access the applications in remote servers. Our system employs a
compression-friendly model, where all the data redundancies are
exploited in the compression viewport. Within this model, we also
propose a unified coding scheme to efficiently compress the vastspectral
screens. Several mechanisms are further proposed to
improve interactivity and reduce the bandwidth consumption in
the system, including adaptive transmission for heterogeneous
display devices. Simulations with real applications demonstrate
that our system significantly outperforms previous thin-client
systems. Especially for video playback under moderate- and lowbandwidth
network conditions, our system can achieve the frame
update rate 5 times as high as the previous counterparts.
