I want to create an interactive multimedia presentation that would
combine some graphics/text with a videodisc output and display the
results on a monitor allowing the user to control the navigation
through a touch screen interface.
I am new to the multimedia/AMIGA world. I have been reading a lot,
but do not have any experience. PLEASE feel free to correct any
misconceptions I may have, with factual information. The following is
my CURRENT understanding.
I would like to compare the SONY VIW-5000 with an AMIGA 3000
configuration. The SONY system is an integrated solution that includes
the monitor and a single box containing the described equipment.
SONY VIW-5000 AMIGA 3000 configuration
-----------------|--------------------------|----------------------------
computer 286(16-bit), 16Mhz 68030(32-bit), 16Mhz
disk drive Connor 40 MB, ?11 ms 50 MB, ? ms
RAM 512K(16-bit) 3 MB, 32-bit
touch screen Sony Future Touch FT1084 13"
monitor 640x480 VGA 640x240
genlock SMI-3081(512K) A2300 or
Supergen 2000
videodisc player
I realize the AMIGA configuration is faster, multitasking, and should
BLOW away the SONY configuration, but the final display has to look
great with no flicker.
The best resolution is available from a genlock that can decode the
composite videodisc signal into RGB and combine it with
the RGB graphics/text into a combined RGB output to display on a
RGB monitor. The best resolution is determined by the lowest resolution
in the chain and the amount of colors available for graphics.
videodisc player best usable display mode

|--------------------> genlock <------------------|
420 TV lines | AMIGA - 640x480 4/64 colors or
| 320x480 16/4096 colors
| SONY - 640x480 256/?262K colors
|
SONY - > 400 TV lines |
AMIGA - ? TV lines |
v
monitor AMIGA - Future Touch 640x240
SONY - 640x480
What is the final RGB resolution and how does it relate to TV lines
of resolution(so the video guy knows the output is GOOD)?

I kept this in multimedia because it is a multimedia-oriented discussion. If you feel an uncontrollable urge to scream then feel free to move over to .advocacy.

The 3000 will only flicker if you choose to display it on an interlaced display or you require an NTSC signal. NTSC flickers, so if you eliminate flicker you are no longer generating NTSC video. >The best resolution is available from a genlock that can decode the >composite videodisc signal into RGB and combine it with >the RGB graphics/text into a combined RGB output to display on a >RGB monitor. Then use the VGA compatible output from the 3000 to drive the same genlock that you would have used with the MS/DOS system. -- _. --Steve ._||__ DISCLAIMER: All opinions are my own.

I was using the resolution of the only touch screen monitor I knew about for the AMIGA that works over a serial or parallel port. I called the manufacturer, they said there was a mistake, x240 should be x400. Elographics and MicroTouch also make touch screens, but they work over a serial port or the PC/AT bus. The videodisc player needs the serial port. >3000 is perfectly capable of hooking up to a VGA monitor and displaying >noninterlaced 640x480 graphics directly? (actually I think it is something >more than 680x480 including overscan). I need genlocked output from the 12-bit RGB slot and composite video. From talking with Commodore, the higher resolution(ECS) you refer to will NOT work with the genlock. So in a non-interlaced mode the best I can get is 320x200 with 64/4096 colors or 640x200 with 16/4096 colors. >>BLOW away the SONY configuration, but the final display has to look >>great with no flicker. > >The 3000 will only flicker if you choose to display it on an interlaced >display or you require an NTSC signal. NTSC flickers, so if you eliminate >flicker you are no longer generating NTSC video. I was more concerned with the graphics looking good. With the previous mentioned colors/resolutions available, I'm not sure that's possible. I will address that question to comp.sys.amiga.graphics . >Then use the VGA compatible output from the 3000 to drive the same >genlock that you would have used with the MS/DOS system. >--Steve ._||__ DISCLAIMER: All opinions are my own. > Warren v\ *| ---------------------------------------------- > V {uunet,sun}!convex!swarren; swarren@convex.com Let's say, I COULD use the VGA output from the 3000. I know there are 2 or 3 PC/AT slots on the 3000, but don't I need a bridgeboard to use those slots ? Is the 3000 able to address any PC/DOS boards directly ? How does the 12-pin RGB output from the 3000 get to PC genlock ? Someone help me out here. -Ron
