Requesting a circuit to remove DC from video signal

[Aussie Bloke]

Thanks for the circuit. I gave it a go but got the same results, a distorted picture.

But it's all good now as I've just found another circuit that will limit DC down to 0.2 to 0.6 volts which I guess is pretty acceptable for DVD recorders, I put it together and it works very well. The circuit can be found here http://www.telestream.net/pdfs/app-n..._DC_Offset.pdf . I had to add a 75 ohm resistor in parallel from video signal to ground to make the circuit work effectively to limit DC.

I am using this for the viewfinder output from my JVC GC-3300E colour camera http://www.troysvintagevideo.741.com/gc3300.html as the viewfinder is not working and I want to use a little Casio handheld TV in place as the viewfinder. That circuit has effectively limited the DC from over 3 volts to about 0.6 volts which I guess should be okay for the AV in of a small handheld TV.

hi guys,,,,
That gives about 11v DC out of 9v AC which then is input on the 7805. ... (way above the ones existing on the video signal) and after your comment, ... Instead of your circuit, I would remove the resistor and inductor, ...
