I'm unfamiliar with AV bridging--what do you use
it for?
AVB is a !!! layer2 !!! ethernet standard for audio and video transport,
with precise timing synchronization (house clock like with grandmaster
clock selection), resource reservation and quality of service.
worstcase latency over 7hops: 2ms
needs fast eth at least.
the pro audio industry is presenting first products soon, meyersound
already has it in use in its dmitri.
harman pro (studer, soundcraft, bss, jbl,...), yamaha will support it,
biamp, focusrite, audinate, and many many more...
this compatibility would make such an open interface much more
interesting, i think.
While the FPGA's themselves aren't
prohibitively expensive, the rapid
development boards+software are.
i have a low budget board from xilinx (200$), but
will soon switch to
altera, because the are cheaper boards available (60€)...
