Appendix B: Digital video on the
Osprey 300
The Osprey 300 IEEE 1394 inputs connect to standard Microsoft drivers rather than to the Osprey
AVStream driver. Osprey customers who are familiar with the Osprey 500/540/560 should
understand that the DV implementation is completely different. On the Osprey 500/540/560 cards,
the DV connector and capture hardware sit behind the Osprey audio and video capture devices and
are controlled by the Osprey driver. On the Osprey 300, the DV is an entirely independent device.
If you look at the Windows XP Device Manager after
installing an Osprey 300 you will see something like
this. Under the category “IEEE 1394 Bus host
controllers” there will be an entry for the Texas
Instruments controller on the Osprey 300. This
device is automatically activated whenever the card
is plugged into the system. If you plug a DVCam into
the Osprey card, an entry for it will appear under the
“Imaging devices” heading. Both the 1394 controller
and any devices plugged into it are logically distinct
from the Osprey 300 analog audio and video devices
shown under Sound, video and game controllers.
In theory you should be able to connect any 1394
device to the card, not just a digital video (DV)
source. In this chapter, however, we focus on using
the 1394 connector with DV devices such as
camcorders.
Most major multimedia applications will recognize
DV devices and work with them fully. For example,
we have verified that Windows Media Encoder 9
supports a DVCam attached to an Osprey 300. With
major applications the DV connection should “just
work” and the information here is for background
and reference only.
