S-video/composite video receiver question

[utamav91]

bought a Denon AV-1507 receiver last night and will be connecting it this weekend.

My TV only has a composite video input jack (and a coax of course.)

My DVD player and satellite receiver boxes have composite video and S-Video output jacks.

If I connect S-Video cable from my DVD player and satellite receiver boxes to the S-Video inputs on the receiver, will the receiver play a picture to the composite video on my TV? Or since I'd be running all the video to the S-Video jacks on the receiver, will the receiver only output via S-video?

Or since my TV only has composite video input, do I have to use only composite video connections elsewhere?

DVD>>svideo>>receiver>>>composite>>>>TV?

No, it won't.

The receiver will "upsample" composite to S-video to component, but it won't "downsample" component to S-video to composite.

If you're using the composite output of the receiver, you will only get video from composite inputs - not S-video inputs.

I don't see why you'd want to try this anyway. Any benefits gained from S-video would be erased by changing it back to composite.

DVD>>svideo>>receiver>>>composite>>>>TV?

That will work on some receivers but not necessarily all receivers. Onkyo includes a diagram in their manual that shows all the possible conversions and s-video downconverted to composite is supported. You'd have to check the manual for your receiver to find out if s-video->composite is supported.

Yamaha's like that too, but the last I checked, Denon is not (that may have changed).

I checked my manual's specs...the model or two up does the conversion, but this one does not. I was just going on the theory that maybe sending the receiver a better signal to begin with might result in a better signal once it gets converted down to composite. It was worth thinking about anyway.

We're replacing our VCR at some point soon with a DVD recorder/VCR combo unit, and it'll have S-Video jacks. And probably a new TV at some point which will have a S-Video jack. And the receiver has composite video jacks too. So at least I'm nicely positioned for the future.

Thanks everyone. Wish me luck on my wiring this weekend. Shouldn't be too tough--replacing an 12-year old Pioneer unit that I bought when the original Dolby Pro Logic was getting popular.

If anyone remembers the old Service Merchandise stores...we used to rewire all the speakers and receivers and home theater demo area stuff probably once or twice a year so it got to be fairly routine. I always liked the challenge of doing it and helping customers with all their setup questions---every home theater was a little different it seemed. A good diagram and wire labeling go a long way in making a project like that easier and faster.
