Well, did I open a box of worms....

I thought I had it down until Pandy wrote,

"Use RG59 for the video and digital audio. There is no such thing as 'digital coax'", in response to my question,

"
The Componant video-in uses an RCA type of connector, right? Does this require a higher end more exotic cable for the best picture."

I was asking about the output signal from the Sat. receiver or DVD. I understood about the signal from the dish to the receiver and the cables for that.

Now with all of your helpful input, I finally get it.

I buy specific component video cables to connect from my Sat receiver and DVD to the TV. Ya hooo!!!

Does anyone have any idea what Pandy was talking about?

Pandy got confused by the term 'digital coax'. This is not video cable at all, but is digital audio in an RCA-type cable. Yes, they both say 'coax', but they refer to different things.

mason, You should also know that component video is used separately for HDTV and SDTV. EX: the Dish Network 6000 HDTV receiver has component outs that ONLY output HDTV signal. So if you have an older non-HDTV, you probably have to hook it up via s-video with the Dish 6000. More ex: The Philips 34PW9815 HDTV has two component inputs, one for SDTV, like a DVD player; one for HDTV, like an HDTV satellite hookup. So you need to make sure the proper cable goes to the proper input.

Actually, you don't NEED fancy RCA-cables for 'digital coax' or component video hookups, but I wouldn't be caught dead without high-end cables. The difference is instantaneously noticeable or audible. btw, Monster Cable is not high-end, just over-priced. Personally, I'm switching from Monster to bettercables.com cable.

robb, s-video has 4 wires, not 2; it's a mini DIN-4 connector, not coax in any way. It's the same cable (strangely enough) as Apple Computer's ADB keyboard/mouse cable. And RCA cables are not called coax generally (although they are single wire cables), so composite video is also not coax, at least in common terms. You are talking about antenna, cable, satellite and professional hookups, not home theater.

Spiky, based on your post, i guess you are unaware of exactly what coaxial cable is. It is a cable with a center conductor, surrounded by an insulator, surrounded by another conductor called the sheild.
I never said svideo cable had 2 wires, i said it has 2 coax cables in it, which is a total of 4 conductors. Remember coax cable is 2 conductors. All video signals, weather composite, component, or svideo, uses coax cables. There is NO such thing as digital coax...thats just marketing talk.
Finally, An ADB cable does not contain any coax, and is probably the worst thing to use for svideo.
Spike, you should brish up on your terminology, your as confused as other people.

robb,

Digital Coax IS a term for audio. Perhaps you've never looked at that side of your DVD player.

Toslink/optical vs coax. Sound familiar? Transfers DD and DTS encoding over one cable still in a digital encoding format. Nothing to do with video. That is where the term first came up in this thread (3rd and 4th comments), so that's what I commented on. At this point I don't care who, but somebody misunderstood the offhand comments about audio to be about "marketing hype" video cables, and away everybody went blasting this'n'that!

Most s-video cables are not that well made so as to have "coax" be an appropriate term. At least not in my personal lexicon.

If high-end s-video cables are truly double-coaxial, great! I'll be buying them in the next month anyway, so bully for me!!



I just love those who flame because they like to flame. Goodbye.

Ah, ok spiky, i see you're backpeddling now.

But noone has mentioned what the difference, if any between component and RGB. I have an older high quality TV set that has RGB inputs. The question is if there is a sync signal on one of the connectors. Is component the same (amplitude)and complete compatibility as RGB. The connector on the back of my TV is not BNC connectors as you would expect to see, but a funny sqaure looking connector that has angled pins. Any idea? It looked like connectors that were on early studio equipment. Any assistance would be greatly appreciated. I feel that this would be better than the simple composite signal feeding my TV set. The TV set does not have s-video or I would already use it!

component is not the same as RGB. Component is the luminence signal and 2 colour difference signals. RGB is 3 luminance signals representing the 3 colours.

Robert:

Most RGB-capable systems use either sync-on-green (where a composite sync pulse is combined with the green channel), or have a separate sync channel or channels. Some (now very few) systems used a single separate sync channel, called "composite sync" because it included both the horizontal and vertical pulse information combined. It's basically the same sync information that's found in composite NTSC video.
True component systems (Y/R-Y/B-Y) have composite sync on the Y (luminance) channel.
S-Video systems have composite sync on the luminance channel. That makes the luminance channel of the S-Video signal simple black & white video.
The more common separate sync channel format found in RGB systems uses completely separate horizontal and vertical pulse channels. So the system would include 5 connections: R, G, B, H, and V.
If your system has no input for sync, it uses sync-on-green (if it really is RGB; check to see if it is really Y/R-Y/B-Y). If there is 1 sync input, it uses composite sync. If there are 5 total inputs (RGBHV), it uses separate everything.
Now, as far as your "funny square-looking connector that has angled pins", I have a guess: It could be the old EIAJ connector found on many old Sony U-Matic VCRs and some TVs. If so, the signals are NOT component. This connector was used to make connections simpler between a VCR and a TV. It includes composite NTSC video and two analog audio channels on an 8-pin connector. Not all of the pins were used in one direction, of course. This connector was capable of being used in both directions, having 2 video coaxes and 4 audio paths. The ground/shields were partly in common, as I recall, which allowed this.

coax means only one thing , it means the cable is a dual axis cable. CO-AXIS
so coax could be any damn cable with a dual axis.

"so coax could be any damn cable with a dual axis."

Such as...coaxial cable?

Did you have a point to make?

Your first post was replying to a 4-year old thread?

Not off to a good start, are we?

wonder how Mason is doing

Interesting. This thread was dead before anybody now replying was even registered. Now that's OLD.

Spiky look at the previous page, you responded to this thread before :-)

don't you remember RC existed long before we needed to register, back in those days anyone could use any name (not PW protected IDs)

See, that's what incomplete research does for you. I glanced at the post date and the Joined dates and figured I was done.
LOL!
