Help me change 4:3 in to 16:9 out (anamorphic not scaled)

[Nardella]

Can the Video Experimenter add black bars to a 4:3 input to get a 16:9 output with text and graphics displayed on the black bars?

If not do any of you know a way to do this with additional hardware?

Can the Video Experimenter even work with 16:9 input and output?
Thanks,

There’s nothing in the NTSC or PAL signal about the aspect ratio, so yes a signal with 16:9 image works fine.
Here’s a thread where I talked about how to add a black (dark gray really) bar at the bottom of the screen using a MOSFET.

I used the MOSFET (also works with a 4066 analog switch) to turn the picture “off” to make a black bar, and then overlayed text onto it.

Problem is, the bar is only as wide as the frame buffer you have defined (e.g. 128×96) so it doesn’t go all the way across the screen. You can try a wider resolution to see if you can make the bar wider.

Hope this helps.
