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.

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)?
