RGBs to RGsB

Post by citrus3000psi »

The sync would be clean. Anybody have a passive circuit for this?

I want to build a Dreamcast Scart cable that will output 480i/240p or 480p with the flip of a switch built into the scart head.

As I was typing this I guess its not necessary to conver the RGBs to RGsB. What is necessary is that I need to convert RGBHV to RGBs.

Does anybody have a good solution for that.

Does the Dreamcast's multi-out not already provide C-Sync?

Either way, you should be able to form CSYNC using a simple XNOR logic gate (VSYNC xnor HSYNC), assuming both are active low.

What are you trying to do?

Convert RGBHV to RGB + Composite sync?
