So I have NTSC video on a composite cable. Is there anyway I can accept that as input to the Arduino Mega and then calculate the average color? I'd like to do it realtime, like at least a few times a second. I'm a total newb, but I have a feeling this is probably impossible with the Arduino's memory limitations. If it is impossible, does anyone have suggestions on what kind of hardware could do this and then I would just send the data over to my Arduino.
Any ideas would be appreciated :)
