Watch
any science fiction classic and you’ll see a key
piece of futuristic technology - the mobile videophone.
Countless space heroes have used such devices
to communicate with their colleagues as they bravely
explore alien worlds. In the real world, however,
there is much to be done before this can happen.
The cost of video processing must come down to
consumer price levels, mobile handsets must be
able to handle processor-intensive video work
and the low picture-quality of video telephony
must be improved.
Transmitting
video over a wireless network is very different
from storing video on a disk. Whenever we send
video over a wireless network, or indeed any other
lossy channel, we find that some of the data gets
corrupted. As digital video is compressed before
transmission to keep the bandwith requirements
low, one small transmission error can have disastrous
consequences.
In
a wireless network, two things are paramount:
quality and latency (end-to-end delay). Alphamosaic,
with its world-beating expertise in this field
gained in both industrial and academic circles,
has the answer.

over wireless networks in the section on error
resilience.
