VIC and RAT use a variation of the 4 clause BSD license which has the
advertising clause requiring authors of all works deriving from a
BSD-licensed work to include an acknowledgment of the original source.

VIC is backwards compatible with NV, on the command-line you can use
'-A nv" to use the variant of RTPv1 used by NV and
'-f nv" to use NV's video codec.

I'm guessing Xerox PARC's Network Video hasn't been maintained in years,
unlike UCL vic.
