Users can now expect the equal level screen
quality at about half of the existing bandwidth. And,
H.264 allows the visual meeting continue even when the network
condition isn't good by providing important improvement
and powerful error-recovery function such ase increase
of mutual gearing in high performance level
etc.
The profile structure of H.264 - the combining of pack
technology- has become much simpler. H.263 had over one
million combinations available, while, in the other
realization between venders, only the basic mode was
used. H.264 deals with three profiles, that is, basis,
main, and extension. As the basic profile provides a
powerful error-recovering tool and low latency coding,
it's ideal for
visual meeting application as a dynamic network such as the internet is required
for transmitting the visual meeting data in a low bandwidth
H.264 technology hasn't reached commercialization, but, as DMB broadcasting by H.264
mode is scheduled, H.264 codec is anticipated to be commercialized after the next year.
H.264 has the potential to combine the consumer picture and
communication picture markets, which differed from each other
in former days. If H.264 circulates as is expected, the visual meeting,
started from polycom visual meeting system, can be reproduced in portable
movie players, TV through cable set-top box, or cam-coders. This means
that 3G mobile phone can be supplied by visual meeting or cable TV. If
this actually occurs, the potential and value of video may be expected
to be infinite.
