Conclusions and Future Research
nDefined transcoding algorithms that take user
preferences and device characteristics into
account, iterate to achieve desired
bandwidth reduction
nIncorporate algorithms into WWW proxy (Rabbit)
nSet up experiments with different client devices (real
or emulated): PCs, WinCE PDAs,
Palms
nFuture work:
–Evaluate
“quality” of transcoded WWW pages (otherwise trivial: drop images completely)
–Proxy:
cache management (support heterogeneous client population) and performance issues (transcoding is not
cheap)
–WWW
document: how to “transcode” whole document, not just individual images
