[comp.graphics] video disk

houghton@silver.bacs.indiana.edu (Ric Houghton) (04/14/88)

   Well, we have finally decided to take the advice of most you and 
consider moving *upto* an Amiga. We have ran into only one problem.
If we are going to shell out the bucks for a graphics station, I 
want to use a video disk.  Pioneer has a model which can be driven
under computer control, only I can't find a controller to drive it
(only minor detail, I'm sure). Does anyone know if these controllers
exist. (Or is it like the OS/2...Only in the minds of a lot of peoplet.)

     Thanks a heap.

Right on!

I believe I've seen the Pioneer box in question - it should have a
standard RS232 port out the back, in which case you've already got
the controller for it. All you have to do is write some Amiga software
to deal with it. If you're luck, they'll accept simple ASCII commands.
I bet if you called up the Pioneer folks (they have some big offices
out here in Jersey) they'd be happy to tell you more or send you
programming/tech info on their product.

Great, keep us posted on how it goes!

I don't have specific references available, but I've seen some that
worked from the ever-popular SCSI...an ideal situation, since *everything*
supports SCSI. You may have to write a device driver, but on the Amiga
this is almost trivial, especially for SCSI and especially if you start with 
with one of the public domain SCSI drivers.

Are you talking CDROM or WORM or what?

The Pioneer Videodisc players Models 6000 and 4200 have regular RS-232
inputs, so all you really need is the serial port provided on your
Amiga.  If you're trying to use one of the older players (models 4000
or 2000) with a special interface, I have some addresses you can
contact for more interface information.

The 4200 model videodisc player includes the ability to overlay ASCII
text (internally generated from the player) over the video.  If you
want more graphics control, you'll have to use a genlock interface
to overlay Amiga's graphics over video images.

Feel free to contact me if you need any further help.

You may wish to consider the Panasonic (Matshusita) optical disc
products: TQ-2026F and TQ-2028F (monochrome).  Each can be controlled
through RS-232 and Panasonic claims to have software for them too.
Features: wired and wireless remote controls, still, frame-advance,
10x fast forward/backward, 0.004x slow forward/backward, features needed
for video production, 24,000 frames storage, random access, $?.  

This is not an endorsement - I'm simply copying from the sales lit.

I've used the Panasonic TQ series optical disk recorders at work.  Except
for ocassional glitches, they work very well.  I believe they cost ~15K now,
though we bought ours for 30K, so the price for this type of device is dropping.

Two drawbacks are that the disks are non-standard -- that is, they won't 
play in the commercial players.  The other drawback is that 24K frames is
about only 10 minutes of full speed video.

The first drawback is more or less canceled out by the fact that the read-
only version of the disk player costs about 1.5K, and it can also be controlled
remotely by RS-232.  We use this system for recording digitally processed
movie sequences and playing them back under computer (PC) control.  The
scientists here get no end of insights by playing the movies at different
speeds and forwards and backwards.  For this type of application it is ideal.

I have used the Panasonic to record Amiga output with considerable success.
You'll need a genlock, and a good video source since the TQ is a little
fussy about sync.  I used the built-in serial port control support in 
VideoScape 3D to record animations automatically, and it worked like a charm.
Good luck.

We use one of Pioneer's LD-V6010 laser disk players on a Sun 3.  It 
has a simple ASCII command language which is input through its serial port.
Information on how to use the computer interface doesn't come with the 
unit, so you need to contact Pioneer's technical support services 
in Long Beach CA and request the technical user's manual.
