[comp.sys.amiga] DCTV information

es1@cunixb.cc.columbia.edu (Ethan Solomita) (10/17/90)

	I just spoke with a tech at Digital Creations to ask
about the DCTV and get a few details straight. It opens a
high-res interlace ... screen which requires 198K RAM. It stores
images on that screen as 'waveforms' and then converts the image
via the hardware (which plugs into the RGB port for display,
parallel for digitizing) to the full-color screen you see. The
vertical resolution is only 300, but TVs are only 330, at least
with our terribly NTSC standard they are. The main advantage is
the color resolution.
	It can take input from video cameras, VCR, etc. The
person claimed that they do some sort of Time Base Correction
software scheme to improve VCR digitizing quality. I don't know
enough about the subject to know whether that is really
important.
	It comes with programs to convert between Amiga
formats,including 24 bit images, and DCTV format. It also comes
with a paint program, although it will obviously not be easy for
other programmers to utilize as its format is totally foreign. It
also comes with the digitizing software and takes about 10 secs
to take the image.
	The rep claimed that it is possible to shrink the memory
requirements for the image down to 46K (?) by cutting down to
65,000 colors. You can play animations using DCTV imagery,
possibly converted from a 3-d program, using a standard animation
program (it is after all just a standard amiga screen from the
amiga's perspective), although one will be provided with the box.
	The list price is $500 and the guesstimated shipping time
is mid November.
