Want to convert S-video to component

Thread Starter 
I have a Samsung 63" plasma. I'm running the DVD and the HDTV from cable to component inputs. I have another video source (TIVO) which won't do component out.

It's impossible to program a macro on my remote to gracefully switch the video source on the TV between component and s-video. So I'd like to convert to s-video from the tivo into component, so I can feed that into my receiver and let it do the switching.

What's a decent, low cost way to do this? (I'm willing to bet "decent" and "low cost" do not play well together).

Thanks,

Eric.

Try kramer electronics, they usually have that sort of thing.

Ofer,
I thought it was not possible to convert s-video to component?

Of course it is possible. It's done by an external comb filter. Hometheater Hifi has a review (a bit old, though) here, where they review then compare the Crystal Vision VPS1 to the Faroujda VP-100:

If interlaced component output (480i) is okay, then the Matrix V3 from Projection Specialists might also solve the problem for you.

A comb filter seperates the chroma from the luma in a composite signal.
An s-video signal is already seperated into Y and C, no comb filter is necessary, in fact, the elimination of the comb filter is one of the reasons to use s-video.

To convert s-video into a component signal. The Chroma signal has to be demodulated and decoded into the I and Q signals, which are furhter processed into Y, R-Y, and B-Y.

By converting to component, are you then losing any of the picture quality. It seems that may lead to data loss?

Component is capable of greater resolution then either composite or YC. Converting composite to component won't result in quality loss, the reverse will.

tvtech1,

Doh - I must've missed my coffee that day. You are, of course, correct. I must've been thinking of composite...

Purchase a used Iscan at audiogon and set the unit to output component video instead of RGBHV. 250 dollars
