VGA to PAL converter ?

Hi, I use a vga ouput to display video from a camera (see attached picture). I would like to add PAL output. I wonder if a single chip which converts vga (analog, digitial ?) to pal exists ? ...

For a "quick and dirty" solution the chips you call out (AD723, ...) may be the best solution. These take analog RGB and convert to PAL or NTSC. Another solution might make use of a digital format converter IC, progressive scan digital RGB to PAL or NTSC. These tend to be hard to obtain in small quantitites as they're geared for the consumer market. If you've got the time and inclination you can create your own PAL encoder in the FPGA as mentioned above. This will require converting from progressive scan to interlaced mode first.
