Hello,

I'm a video signal noob, and have some questions about this module.
At home we have a digital tv decoder, can i put this backpack between the decoder and my tv. So i can see the overlay screen on every tv channel?

and two:
Is it only for NTSC devices? We have only PAL here.

    You might want to ask this in the Propeller forum, up above. There's a really cool thread there already on the topic.

    You can insert the Backpack into any NTSC analog signal path for overlay purposes, so long as the source impedance of the video signal is 75 ohms (i.e. the open-circuit signal level does not exceed 2V P-P). I'm sorry, though: I don't have any PAL software written for the Backpack (no way to test it).
