Connecting iMac to TV decoder

[nikonr]

Hello.

I want to see TV on the iMac.
Is it possible ?
I have 3 decoders.
1) with RCA & SCART outputs.
2) with RCA output.
3) S-Video & RCA outputs.
I prefer to connect RCA or SCART if possible cause the s-video is the main decoder at home but if needed...

Thank's a lot.

p.s.: sorry for any spelling mistakes.

You're going to need a device like elgato's eyetv hybrid.
