S-Video and Comb Filters

[Guest]

Hey everybody I just got my first LD player today so I had a quick question:

If I have a Pioneer LD player with a 3-line digital comb filter and an
analog tube television without any built-in comb filter, I should use the
S-Video connection rather than Composite video, correct? I did some A-B
comparisons between the two and S-Video definitely seemed to win out in
terms of detail and color. I've read some reviews that say Composite can
sometimes yield better results, but that's only when the TV itself has a
better filter than the player, right?

Actual model is Pioneer CLD-S350, TV is a cheapo ESA 27". I'm using
shielded video cables but nothing expensive, just RCA and Acoustic Research.

I used to have a basic RCA Colortrak tv with a cheap comb filter.
Virtually any player I hooked up via the S-Video looked better than
Composite.
I now use a 1994 Proscan tv set with a digital 3 line comb filter.
This filter is equal to the S-video output of the players I've used,
such as the Panasonic LX900 or Pioneer CLD D704. In othe words, if you
do A/B switching between composite and S-Video, you really can't discern
any difference.
However, when you jump up to players with 3D adaptive filters, it's
usually best to use the S-Video output. I have my HLD X9 hooked up via
the S-Video output. You need to, in order to utilize the 3D adaptive
comb filter.
The only true test is your eyes. Compare both of the outputs on the
player and choose the one that provides the least NTSC artifacting! The
one with the less dot crawl on the edges is the way to go.
Use a CAV disc. Do a still frame and then do an A/B comparison. The
output with the less dotcrawl on the edges is ideal.

All televisions have a comb filter of some sort. The comb filter is what
allows the set to display a video signal from a composite video
connection.

There's your answer, then. Your TV player has a better comb filter than
your TV.

Use which ever connection looks better. =)
