I've just bought a Panasonic DVD-S75 player and want to know of the best way of hooking it up to my tv using the RGB scart, along with a digital set-top box which also uses RGB. I've already tried a cheap scart splitter and I get a slight loss in picture quality when both dvd player and digital box are hooked up. Is there any device/way of hooking both up with minimum signal loss?

Cheers

You need a switchbox not a splitter. You can split outputs of a device to different components, however running two source components into one input requires a switch mechanism.

Correct, one does need a switchbox. Try Keene Electronics, they have a number of differing devices that might do for you . . .

Code
BT22 @ £9.99 - Simple two way manual.
SSB @ 19.99 - Three way manual.
BT921 @ 39.99 - Four way (3 scart, 1 composite) manual.
BT945 @ £69.00 - 5 way auto (with remote)
SBX99SE @ £69.99 - 5 way auto (with remote). Very similar to the BT945.
HRS1000 @ £95.00 - 6 way matrix switch with remote. (6 inputs to any one of 3 outputs).
KSC @ £149.99/£249.99 - Keene's own Scart Commander. 4 to 1 or 7 to 1, if using the master/slave configuation.

PS
I use a BT941, the forerunner of the BT945, and find it very good.

" You can split outputs of a device to different components"

He's talking about video outputs, you fscking moron, god, don't you know anything...allah should strike you down...you can't passively split a video signal, it's been explained to you many times but you're obviously too stupid to catch on.....jesus, what a moron you are.

Video signals can be split and much to your surprise it gets done all the time. It is not an ideal situation as signal loss and degradation do happen. The product in the link above does work as a passive S-video splitter. I have also seen simillar products sold for composite, component, RF coaxial and VGA conections. While I have not seen such a contraption for SCART cables, as I have not exactly been looking for one, I am sure they do exist.

G50,

How do you maintain a 1V p-p signal, with a 75 Ohm source impedance, feeding 2 75 Ohm loads in parallel?

I'll tell you, since you don't know. You can't maintain the correct video level into a double termination, this is why you cannot passively split a video signal ( or any other impedance matched signal)

You're not intelligent enough to give advice on this, or any other forum.

I'm gonna have to side with the A-man on this one, as video sources actually put out 2v p-p througth a 75-ohm resistance, which forms a 2-to-1 voltage splitter when connected to a 75-ohm input impedance.

This matters because two input connections in parallel will provide a 37.5-ohm input load, which means the video signal will end up at 0.66v p-p instead of 1v p-p. Once lost, it's gone for good. (amps suck)

Splitting audio signals is a little more forgiving, since they're from constant-voltage sources, and only unusually-low load impedances will cause this dropping of the signal voltage level.

If you believe in high-end cabling at all, the best of which provide an often-unmeasurable signal difference compared to OEM vermicelli, then imagine what a 33% signal loss must do to the precious video.

Kinda off topic, aren't we fellas?

But while we're here... What type of circuitry do receivers that offer multiple "monitor out" video jacks use to "split" -- if I dare use the term -- the signal?

Although not phrased that way, this is an honest question. I know almost nothing about video signals.

" What type of circuitry do receivers that offer multiple "monitor out" video jacks use to "split" -- if I dare use the term -- the signal?"

An Amplifier

So, if I have understood correctly: The key word when discussing the "impossibility" of splitting a video signal is _passive_.

In other words, there is no special problem as long as the degraded signals resulting from the split are properly amplified. Do any other factors apply?

I love this place! I learn something new almost every day. Thanks to all you experts for sharing.
