A VCR with component?

Component is better than S-Video.

Thanks.

I have another question.............

I have a older HDTV 80" ready projection unit from Mitsubishi.
The HDTV inputs are the --5 in 1 BNC pin-type video cable, not the standard RCA type used in todays HDTV televisons.
Is it possible to get some kind of "adapter" that would allow me to have a cable that would be "Pin-Type" on one end and RCA standard on the other end?
Or is there a cable made that does this already?
If I use the HDTV cable box from my cable company they don't have any kind of adapters, ANY HELP WOULD BE APPREACIATED.

I found BNC to RCA adapters here http://www.cablesnmor.com/bnc-rca-adapter.html

I'm not very familiar with BNC connectors, but since you said that the inputs on your HDTV consisted of 5 cables (3 for video, and perhaps 2 for stereo?), that would suggest that you should be able to convert a standard 5-connector Component cable to have all BNC connectors on one end by using adapters such as the ones above. This would theoretically allow you to take the component output from your HDTV cable box or DVD player and have it run straight to your HDTV, that's assuming that the signals are the same, which they might not be.

Do you know if the 5 pins in the input on the HDTV contain the same signals as the standard component signals? ie: video, luminence?, brightness?, left and right audio? If they don't match up, then you might be stuck with having to buy/build some kind of conversion box to sit in between, or just get a new TV =P

>> Re: S-Video vs Component
Be sure not to confuse with component video the almost universal VCR's 2 stereo audio RCA cables and 1 video RCA cable ( =3 wires total ) If you are talking about these RCA connections, then 'S-video' is superior, as the RCA-jack video cable (yellow) is only providing the normal "composite" video through an inferior cable design.

Thesedays the 3 RCA cables are usually color-coded red, white, and yellow. The red and white are audio, the yellow is video. Sometimes the red and white are replaced with other colors ( like green and/or black ) but the video connector usually remains yellow.

If you are using the composite video input/output, be sure to use the 75ohm impedance video cable, and not a standard audio cable.

Many manufacturers make all 3 cables out of the same audio cable to keep things chieap. While the video is ok when using standard audio cables, it isn't quite as good as when you use a true 75ohm impedance video cable. The right cable also allows you to use longer cables.

If they are using true 75ohm impedance cable, it is usually (but not always) thicker than the audio cables.

Yeah, don't confuse Composite and Component. Composite is the yellow. Component is the blue, green, red. Many people confuse them because of the similar names and similar connectors.

Quality from worst to best:

RF/Coaxial
Composite
S-Video
Component
VGA
DVI/HDMI

Some comments on Adam's excellent summary. DVI can include BOTH digital and/or analog video signals.

DVI-A is analog video only
DVI-D is digital video only
DVI-I allows both analog and video signals, so video quality can depend on whether your display is using the analog or digital signal (some displays let you choose)

More info at:
http://www.datapro.net/techinfo/dvi_info.html

I'd slightly modify Adam's list to split the DVI into the categories as follows:

RF/Coaxial
Composite
S-Video
Component
VGA
DVI-Analog implementation
DVI-Digital implementation

DVI-A is used by most everyone that uses the DVI - VGA adapter for older, usually CRT based monitors. Up until a couple of weeks ago I used this on my Veiwsonic PF-815 22" CRT.

>> Re: S-Video vs Component
Naming it DVI = Digital Video Interface is misleading, as it does include analog capabiliity. But, there are analog devices/displays out there that use the DVI style connector for analog signals but don't require a VGA adapter. I suppose it was also seen as a way to allow video card manufacturers to migrate to the DVI connector standard while being able to sell to both analog and digital display markets. The ability to use a simple non-active VGA adapter on one or both ends as needed increased the marketability even more.

Then along comes the HDMI = High Definition Multimedia Interface that is intended to be an all in one interface, but it's STILL EVOLVING and has higher bandwidth. So, we should probably change the above list to...

...
DVI-Digital
HDMI
HDMI 1.3


Note:
HDMI = 5 Gbps bandwidth
HDMI 1.3 = 10.2 Gbps bandwidth

John,
I wasn't trying to indicate that this was the ONLY use of DVI-A, but the one most used, at least by me.
I was trying to answer Water Drops question as to who and/or what used the standard.
I am aware that there are some DIRECT DVI-A interfaced displays out there, but most of them, with the exception of CRTs have rolled off the back-end.

Gerritt

P.S. I'd have to think 3 times before I'd argue a technical issue with John!

No worries. I was just trying to include more detail and examples for what is turning out to be a less than clear situation.

I also like the guide at:
http://www.datapro.net/techinfo/dvi_cables.html
Although, it would be better if it talked about gender and dual-link set-ups as well. It's something the folks at local computer and 'hi-fi' stores around here could use.

Hey, being that we're off on a DVI discussion.....
I've got a system that has the "DVI" style connector on it but the 4 pins beside the "blade" type insert are missing...
Anyone know exactly what this is?

Thanks,
Does anyone know of a VGA (Sub-DB15 to DVI-D Dual link) adapter that will allow the use of old CRTs with this interface, or where to buy the adapter?

DVI-D to VGA? No idea, but why would you want to do that?
DVI-I / DVD-A to VGA? Sure, they throw one in with most video cards. I have like 4 lying around.

Both serve different purposes. S-Video is found on almost everything, and is amazing quality. But Component is better overall if you had a choice to pick one.

HDMI is like Component, but the Component is a little better in playing regular DVD's where as HDMI is better with progressive DVD players & such.

McFly,
So do I (I've got tons of converters). What I have is a Dell Optiplex that has this twisted output on the back where the DVI connector has the blade and not the extra 4 pins....thats WHY!
Now that I'm trying to do, is to hook this up to a CRT I don't have the male DVI to VGA connector as all of the ones that I have, have the extra 4 pins around the "blade" connector. I need a converter that does not have these pins.....OK?!
Jeeze, If this was standard, I'd feel like an idiot.
So, please knock your self out...I'm used to it!

Gerritt,

Without those 4 pins around the blade, I'm pretty sure that means its a DIGITAL ONLY link. So, a simple adapter doesn't exist to convert it to analog VGA. It would have to go to an active device of some sort to re-create an analog signal for the VGA input CRT.




edit to include more info:
If the connector consists of blade + 1 set of 3x8 pins, then it's DVI-D Dual-link.
If it consists of blade + 2 sets of 3x3 pins, then it's DVI-D Single-link.
See the website I mentioned above for more DVI descriptions:

Radio Shack in the USA or The Source from Canada probably have addapters to connect anything to anything analog/digital regardless.
