Hi,

Subject: Re: Saving presentations to video tape

Hi,
for recording SVGA animations or VGA presentations we currently have
the following solutions for you over here in Germany:



We currently have three solutions for you:

1. 24 bit to TV converter box which is a box connected outside of the PC to
the SVGA card via its VGA connector. There must be a TSR program run
in the background to change automatically the scanning frequencies of
the ET4000 board. This works also very well with win3.1
It supports up to 800x600x65K colors and 640x480 with 24 bits
color (true color) on the Genoa 7900 ET4000 SVGA board.
 It has  Video (FBAS) and Y/C (SVHS/HI8)
outputs.


2. VGA2TV adaptor. This is an internal board which is hooked inside
the PC to the feature connector of the VGA card. So the VGA or SVGA
board must have a feature connector !
The VGA2TV samples the contens of the VGA RAM into its own dual ported
RAM and gives it out with the Video scanning frequencies to its Video
(FBAS) or Y/C output.
It also has a Genlock possibility. So it can be used to do titling in
front of a holiday movie video tape running in the background of the
computer graphics titles !

Input of the external video source could also be FBAS or Y/C.

 It is called M2150 for the PAL version.


3. VGA2TV PRO with integrated Flicker fixer. This is the new release of
the VGA2TV board. It has also a flicker filter for making the
Interlace flicker much less visible. It also has OverScan/Underscan
feature and the position of the screen on the TV set could be
controlled via software.
This board is of course more expensive than the older VGA2TV, but
still either cards are sold.
The new one is called M2200 .

Both max resolutions to convert with these VGA2TV boards are
640x480 with 256 colors ! It has the advantage, that it does not need
any software ! Just plug and it plays !
