- Hi,
- for recording SVGA animations or VGA (also 24 bit support)
- presentations we currently have
- the following products 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 SVGA board. This works also very well with win3.1
- It supports up to 800x600x 65K colors (only PAL) 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.
-
- There is also a version of this box with additional RGB output, so you
- get the best picture quality on a TV-set with SCART - RGB-inputs..
-
- The VGA Monitor is also connected to the 24 Bit to TV converter box,
- so if you don't start the driver software, your system is like normal:
- You see the picture on your SVGA monitor.
- The DC-power comes from the keyboard connector, so you don't have to
- fiddle around with AC-DC-aptor power supplies !
-
- Just don't start the driver software, if you don't need video out !
- The box doesn't interfere with your daily work. Just forget it behind
- you PC.
- If you need video out, just start the 2 KBytes driver software and
- then you can toggle between video out and VGA monitor display with a
- hot key !
-
- The driver software is adapted to SVGA FLIC-files from Autodesk
- Animator PRO to give a 640x288 x256 colors Fullscreen-Overscan display
- on PAL TV-sets. This works by using double scanning with 50 Hz
- Non-Interlace !
- Every scanline from the 288 is scanned twice, so it gives 640x576
- Fullscreen display ! (with no flicker)
-
- This way you can record your favourite SVGA animations to tape without
- seeing any black borders !
-
- There is also a NTSC version available, which works only up to 640x480
- with 16, 256 ,32K , 65 K and 24 bits colors !
- On NTSC model the 640x480 mode is already Fullscreen !
-
-
- It also works with the new Hicolor FLI player, so you can play and
- record hicolor animation directly from a RAMdisk to VCR tape..
-
- You don't need NO single frame accurate expensive VCR anymore !
-
-
- Cause it works also with win3.1, you can record all your daily windows
- application work to video tape !
-
- If you have a presentation program like Microsoft Powerpoint, no
- problem ! Just record your presentation to video tape to show it via
- video cassette to everyone, who has a VCR !
-
- In windows the 24 bit to TV-box works in 50 or 60 Hz Interlace to
- display the 640x480 or 800x600 (only PAL) scanlines.
-
- This gives a little flicker on Menu-buttons, which have only very
- small horizontal lines with big contrast in color. So use an
- appropriate color palette under windows to reduce flicker..
-
- With the Y/C output (SVHS/Hi8) you almost get SVGA monitor quality on your
- video tape !
-
-
-
- 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.
-
- This unit is called M2150 for the PAL version.
- M2100 is the NTSC 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 !
-
-
-
-
- Please let me know, what you need.
