Compatibility example
It’s possible to run a 1394a and a 1394b camera on the 1394b bus.
You can e.g. run a STINGRAY
F-033B and a MARLIN F-033B on the same bus:
•
STINGRAY
F-033B @ S800 and 60 fps (2560 bytes per cycle, 32% of the
cycle slot)
•
MARLIN F-033B @ S400 and 30 fps (1280 bytes, 32% of the cycle slot)
Bus runs at 800 Mbit/s for all devices. Data from Marlin’s port is up-converted
from 400 Mbit/s to 800 Mbit/s by data doubling (padding), still needing 32%
of the cycle slot time. This doubles the bandwidth requirement for this port,
as if the camera were running at 60 fps. Total consumption is thus
2560+ 2560 = 5120 bytes per cycle.
