Well see the problem with A/90 is that is is woefully inadequate for
doing anything but the simplest of datacasting systems. And when you
move to creating a larger system the first thing you find is that the
A/90 spec is woefully inadequate for building a baseline datacasting
system. You just can't build anything on top of a SAP/SDP announcement
system that was originally intended for use in campus video conferencing
networks. This is a dead duck.
The only real solution is to look to what FLUTE on DVB and the IPG work
is accomplishing, or to build a proprietary system. Most data
broadcasting software manufacturers provide API interfaces on all target
platforms though (Linux, Windows, etc.). Funny that the one you
mentioned (to the best of my knowledge) does not.
