What are Red blue green inputs used for on TVs?

[Delirious]

Just curious since I have them but don't use them...

Also can you put a red yellow white hook-up in the red blue green inputs?

 

[Mark T]

I believe they are component inputs. I use the component outputs from my 360 to play in HD. http://en.wikipedia.org/wiki/Component_video

They are colour coded to correpond to the correct input. I believe the red and white are for audio and the yellow is for s-video. Example below shows audio cables on right hand side and video on left.

 

[Delirious]

I see except mine doesn't have the extra red and white

I meant could you use a red white and YELLOW hook-up in the red blue green?

No, you can't. Physically the plugs fit, but they carry different signals.

red-green-blue carry specific components of a video signal: http://en.wikipedia.org/wiki/Component_video

red-while-yellow is a mixture, yellow is a basic video signal, red and white is audio: http://en.wikipedia.org/wiki/Composite_video

Ok thanks for the help

I know it's not what you were intending, but you can use the yellow/red/white (composite) cable in place of an RGB (component) cable. The signal carries just fine - you'll just need an additional red/white (audio) cable as you are going from 3 wires to 5.

On that note, component cable is usually cheaper and better quality than comparable composite cable these days. They're the same thing, but component is usually in greater supply.

EDIT: nevermind, I misunderstood TB.

 

[TB]

Can you give some more insight into this?

My DVD player has both composite and component outputs, but before I bought my new TV, my only option was the composite. In my haste to get home to try out the new TV, I forgot to pick up a component cable. Since I have a ton of composite cables laying around I decide I might as well try it out. I went from the DVD player's RGB to a composite yellow/red/white to my TV's RGB, making sure to keep the colors in the right spot so red went to red, green to green and blue to blue.

Edit: I just saw that you said to not bother, but as I've already bothered...

Thanks anyway!

I misunderstood you, as I thought that you mean that you can feed a composite signal into a component input. A bit later, I got that you and Omnis meant that you can simply use the same lead to transport composite as well as component signals, which is absolutely correct.

Do you think it would make any quality differences for my PS3 on my SDTV if I switched from red white yellow to RGB+red white?

 

[the Interceptor]

The picture quality of a component signal (red+green+blue) is far superior to the quality of composite (yellow), so in short terms: yes!

A composite signal is about the most basic and worst image quality you can get at all, while a component signal is just below a digital one (DVI/HDMI)

 

[TB]

Does your SDTV even have component inputs?

Of course, when I bought it, VCR quality was awesome.

Edit: composite can handle SD video only. Component can go all the way to Full HD, so yes, if you can, make the jump. 👍

 

[Delirious]

Like I said this is a standard SDTV at 480i on a PS3, so still go component?

 

[the Interceptor]

Yes, absolutely. You may think that 480i always is 480i, and that a cable might not change that. But the video signal undergoes significant modifications accompanied by well visible image quality loss to go through the yellow plug, while it is very well maintained and basically unprocessed when it goes through the component trio.

 

[Delirious]

Thanks again for the help

 

[the Interceptor]

Glad to help. I did wrap my head around all this video stuff some time ago, so I did ask myself those questions already.

People pay to have old consoles modded for component rather than composite (I'm only replying now because this has examples). So, very yes. Text will be much easier to read, notably, and colors will be far more vibrant. There will also be less blurring.

I believe they are component inputs. I use the component outputs from my 360 to play in HD.

Just to be clear, although technically speaking component cable is capable of transferring a 1080p analog signal, because there are almost no consumer displays that can accept a 1080p signal via component, you are limited to 1080i or 720p via component inputs.

If you have a 1080p display, or even a digital display (LCD, DLP, PDP, LCoS/SXRD/D-ILA) , then HDMI or DVI will likely give you the best possible picture quality and in the highest possible resolution. 👍

On that note, component cable is usually cheaper and better quality than comparable composite cable these days. They're the same thing, but component is usually in greater supply.

Good advice. It's also important to know that besides having typically better cable construction, most decent quality component cable will have significantly more shielding around the cable then what you'll most often see with composite cable.

Because Composite, S-Video, and Component, can only carry an analog signal, it's very important to be sure the cable has decent shielding, as analog signals are more sensitive to signal interference than digital signals.

If you see lines scanning across your screen, you can be relatively certain it's due to signal interference.

Like I said this is a standard SDTV at 480i on a PS3, so still go component?

It is very rare to see a 480i SDTV (I assume a CRT?) display have component inputs. However, if it really has *component inputs on the back, then yes, that is the best choice.

*RCA jacks marked with Green (Y), Blue (Pb/Cb), and Red (Pr/Cr):

• Green = Y (this carries the luma, aka brightness)
• Blue = Pb/Cb (this carries the chroma from blue to luma)
• Red = Pr/Cr (this carries the chroma from red to luma)

As your display is analog, if it has a component input it will likely use the YPbPr notation. Digital displays typically use the YCbCr or YPb/CbPr/Cr notation.

I feel special. The AQUOS accepts 1080p flawlessly over component from the Xbox 360 (something that few people believe is possible).

I too have a display that accepts a 1080p signal via component:

However these are both rare exceptions, and the unfortunately reality (at least for those with X360's with no HDMI and 1080p TVs) is that the vast majority of 1080p displays can not except a 1080p signal via component, and many have poor deinterlacers, thus why many owners of those displays when feeding a 1080i signal to their TV find it doesn't look any better, and sometimes worse than a 720p signal.

In fact, the first couple generations of AQUOS 1080p displays from Sharp also could not accept a 1080p signal via component, and that feature was limited to only the very best video processors.

Even today, 1080p via component is still generally limited to only the higher end displays featuring the latest video processors.

However, as were are dealing with digital data, ideally you don't want to use analog component any way, so for those with displays with HDMI and DVI, unless they have to use component and the signal is from a native 1080p source, there should be no reason to fret over whether or not it accepts a 1080p signal via component.
