ViXS Systems from Toronto, Ontario has announced the
XCode chip, which they say will adjust MPEG formats, bit rates, and
resolutions on the fly as data moves through an IP network. At a
minimum, this means the part can format MPEG1 to MPEG2 to MPEG4, and change resolutions from QCIF to standard to high definition and back again, depending on network bandwidth availability.
