- The Vdeck (CVD-1000) supports any computer with an RS-232c compatible serial
- interface as well as the Mac. It uses the VISCA protocol so upto 6
- additional VISCA products (eg. more Vdecks, Vboxs, or EVO-9650
- w/EVBK-66). Xobj's are availble from Abbate Video (sorry don't have
- their number).

-
- EVO-9650 requires the EVBK-66 interface board to make it VISCA
- capable. Without the board, it can still interface to a computer with
- an RS-232 port. The EVO-9650 is an industrial grade model and thus
- the protocol it uses is of Sony's higher end - namely a variation of
- CRV protocols.
-
- Both decks support time-code as specified for the 8mm format. In this
- case the timecode is written in a special area of the helical scan and
- can thus be striped onto existing tapes without using an audio channel
- or disturbing the existing video.
-
- The two decks are meant for two very different markets. The CVD-1000
- is meant for low cost desktop video and multi-media. It can search
- down to a frame much more quickly than a PC-VCR and is dead accurate
- (+/- 0 frames). However, it cannot edit with frame accuracy.
- Properly written software can get very close (+/- ~4).
-
- EVO-9650 is specifically made for the CG animation market, but can
- also be used in editing applications. It is capable of single frame
- recording and can edit down to a single frame. Thus the higher price
- tag. It also has a built in digitial frame buffer that can be
- configured as either a TBC for the input video during recording, or an
- output TBC and video processor.

- Well consumer VCR's can be computer controllable. Take for example
- machines using Sony's LANC protocol as well as Panasonic machines with
- Control-M. It's just that most of these machines are not terribly
- accurate when searching since they are dependent on the consumer grade
- mechanism.
-
- If you don't need frame accurate searches then this solution might be
- okay for you. You can often do very simple cuts editing with such a
- set up. The Sony Vbox (CI-1000) interfaces you to the Control-L
- products using VISCA (for daisy chaining). For Panasonic there is the
- Selectra Vu-port. I think ARTI also has an interface that can handle
- both protocols.
-
- I recommend that you try to find a video store that is knowledgeable
- and has experience with each product. Some Sony computer dealers will
- soon be (if not already) authorized as multi-media dealers and can
- demonstrate to you the Sony products. Most of these will probably
- have other setups as well.
-
- I hope I have been able to clear up some questions that have been
- asked here. As always anything I have said is my opiniion and does
- not reflect the views of my employer.
