I called AT&T for some information about their TrueVision High Color
Resolution Imaging products.  For anyone interested, here is the info
taken mostly verbatim from the AT&T brochure.  It is probably biased
but at least it's not copyrighted.
All of these boards are for the IBM (PC, XT, AT) and compatibles.
Has anyone out there tried any of these boards with or without AT&T's
software?  I'm looking for a review.

Image Capture Board (ICB):
Grabs an image from a video camera or VCR (composite video) in 1/60 second,
digitizes it, and can display it on analog RGB or composite video (NTSC).
Resolution:	256 pixels x 256 pixels x 32768 colors;
		All colors displayable simultaneously.
Display:	128K bit-mapped.
Programable:	Odd or even feild capture (1/60s is only one pass).
		Interlaced or non-interlaced video output.
		Application interrupt on vertical blanking or specified pixel.
Settable:	Color (output), hue, saturation and contrast (input).
Price:		$1295.

Video Display Adapter with Digital Enhancement (VDA/D):
Displays a digital image on analog or digital RBG or composite video (NTSC).
Resolution:	256 x 256 x 32768 colors; 256 colors simultaneously.
	    OR  512 x 256 x 16 colors (8 colors x 2 intensity levels).
Display:	64K bit-mapped.
Programmable:	8 Color look-up tables; each with 256 of 32768 colors;
		(displays up to 4 images in different screen areas--
		1008 colors on screen simultaneously but not blended.)
		Interlaced or non-interlaced video output.
		Application interrupt on vertical blanking or specified pixel.
Price:		$695.

Truevision Advanced Raster Graphics Adapter (TARGA):
There are several versions of this board.  They all capture in 1/30s from
camera or VCR.  Hardware zoom (2X, 4X, and 8X).  Smooth independent vertical
and horizontal scrolling.  Bit-pane masking.  "Robust" gen-lock capability.
Up to 512 x 420 pixel resolution depending on color depth and model.

Truevision Image Processing Software (TIPS):
Airbrush defects.  Change colors.  Copy screen portions and blend.  Move,
add, and remove.  Superimpose text and graphics.  Drawing functions:
lines, polygons, brushes, patterns and fonts.
For VDA/D $250; ICB $695; TARGA 16, 24 or 32 $1250.

I have no affiliation with AT&T (don't even own stock)--just wanted to pass
on some information that I got first-hand.
