Subject: A Program to watch TV on you VGA with a Targa Board...
Organization: Purdue University Engineering Computer Network
Date: Sun, 20 Dec 92 21:58:33 GMT


	I have uuencoded a program below that I wrote a few
weeks ago to capture live video on my targa adapter and transfer
it the my VGA adapter.  It is very crude and need massive work, 
but it does function.  It requires that you have a Targa+ 16,32, 
or 64, the TARGAP.SYS driver loaded, and a VGA adapter (generic)
It will capture frames from the targa NTSC Live video port and
display them on you vga screen.  The color sucks.  I am just using
2 bits green, 3 bits red, and 3 bits blue to get 256 colors. (the 
pallete it set up before hand..) It captures in Zoom mode, so
it does a 256x200 capture.  You need to set your Targa board to
NTSC Interlaces 512x400 16 bit.  I will do some more work on the driver
this week and see fi I can get it into SVGA modes, and some dithering
on the color. Let me know if anyone else has any ideas of ways to
improve it. (btw, the code is written in Assembly and C, Borland C++
3.1 with the Targa Devlopers Toolkit (ported to BC3.1)
