The Philips BTS Media Pool audio/video storage system uses HP-UX
workstations for the front end, which could obviously be replaced at
lower cost with FreeBSD systems. The back-end storage and channel
switching is done with 68360s running VxWorks.
I hadn't thought about it, but with a good video board or two and a ccd
driver, you could do quite a reasonable job of a one or two channel
storage pool and editor using FreeBSD.
Last year, we prototyped an entire three-stage switcher on HP-UX and
FreeBSD at BTS. The switcher code was all written in C++, and the
lowest driver layer was easily subclassed to run on the custom BTS
hardware, or as a simple ASCII output on UNIX. Our "vitual" switching
speeds were certainly better on a Pentium 133 than the real hardware,
which was a 16 Mhz 68HC000. ;^)
