I am working on a project that will output either NTSC or PAL video.
The video is mainly text (color and Hebrew text) on top of a background image (that I need to download to the microcontroller).
The board has a UART input and a PAL/NTSC output and according to the UART input different text is displayed (very slow rate).
If it wasn't for the background requirement I would probably try to implement the many hobby projects using a resistor ladder to output composite video using a simple microcontroller but that is not an option.
I did not find much information on making a cheap and relatively easy solution on the internet so what components would you recommend for this circuit?
