| Need to build On-screen display for VGA |
| << < (8/8) |
| Dicko101:
I need a similar solution although this all seems out of my depth now. I want to show Credits remaining and a timer over an arcade game in my store over VGA for PC or some other way for Playstation, I thought it would be simple but apparently not. |
| Dicko101:
Would it be possible to manipulate just the red channel of a VGA source to do very basic red text? |
| Berni:
Yep you can inject only into the red channel, the other colors will simply 'ghost' trough it, so if you do it on a cyan background the text ends up white instead. But injecting the signal in is usually the easy part, the harder part is extracting the timing information from the existing video signal and syncing your overlay signal to it. Tho on a PC you can probably do what you want all in software. |
