queries in the wake of a bus reset (e.g., HD-Connect LE™ and a PC or
Mac), communications between HD-Connect LE™ and an HDV device
may fail. This is known to happen with the Canon XLH1 camera. This
seems to result from queries from HD-Connect LE™ and the computer
arriving at the HDV device too close to one another. It is best,
especially with the Canon camera, to include only HD-Connect LE™
and a single HDV device on the 1394 bus and plug a computer in only
to run the update or controller application for HD-Connect LE™.

Avoiding Avid Auto-Configure. Rather than use Avid’s automatic deck
configuration, select Generic Play Deck as a specific device-control
template.
5)
Avid Check Decks Retries. If a Check Decks operation from Avid fails,
just do the check again. Testing has shown that the Check Decks
operation sometimes sends a couple of lead bytes that cannot be part of
a legitimate RS-422 command.
6.2 Frequently Asked Questions
1) What are the capabilities of HD-Connect LE™? The HD-Connect LE™ is
a compact HDV
→
HD/SD-SDI converter box with component (HD/SD)
and composite (SD only) as well as LTC and AES audio outputs. Deck
control is supported via RS-422
→
1394 (available now) or 1394
→
RS-
422 (upcoming feature).
2) Can you perform HD-SDI
→
HDV conversions? No, the box only decodes
(HDV
→
HD/SD-SDI); it does not encode (HD-SDI
→
HDV) video/audio. An
economical HDV encoder is about 12-18 months away.
3) Can I copy an HDV tape to HD-CAM deck? Yes, simply connect the HD-
SDI output from the HD-Connect LE™ to your HD-CAM deck. The video,
audio, and time code are all carried through this single connection.
4) Can I edit in HDV and then output to HD or SD decks? Yes, one of the
advantages of using “native HDV” editing with the HD-Connect LE™ is the
ability to output your finished project in either HD or SD formats (though
not both simultaneously). Supported decks include HD-CAM, DigiBeta,
DVC-Pro HD, and BetaCam SP.
5) What is the frame latency through the box? There is a latency of one to
three frames through the HD-Connect LE™. The overall latency from a
live camcorder shoot is about eight to ten frames, due to the frame delay
in the camcorder.
