I have green blue red component on back of hdtv but dont have red green blue on back of hd box. ?

Question

I have the red white yellow video cables hooked up but i heared that the red green blue component cables would give me a better picture on my standard channels on hdtv because they are not near as nice as the hd channels.So if I purchased the component cables where would i hook them up to ? Would I have to remove the composite cables and just use the component in their place enen though they dont match up?

Answer 1

Your source needs to have a component output if it dosen't use the HDMI output of your HD box providing you have one to connect to your HDTV. xD

Answer 2

I think you should call the company..kk

Answer 3

even though the box and your bill may say digital it may not be a true digital signal.

In most cases the older boxes only receive the digital menu and therefore can legally call it digital, even though most of the programing is still analog. couple with that the fact that you can only output a analog composite signal means no HD.

So either call the Cable company or tell us exactly what you have for equipment.

Answer 4

Unfortunately, you can't do that.  It appears you have a regular cable box and not an HD one.  Although component video has the capability of a better picture,  your cable box does not support component video since it does not have the correct connectors ( red, green and blue ).  

However, if your cable box supports s-video and your HDTV also supports s-video I would try an s-video cable as that might improve the picture a bit.

Answer 5

IF the cable box is HD it should have a HDMI output (small rectangular port). If so use that with an inexpensive (no need to pay more than about $10-20) HDMI cable to connect to the TV. It carries SD or HD video and sound simultaneously.

IF there is no HDMI it probably isn't an HD box.

If you do have an HD box and it doesn't have HDMI or component you need to change the box (call the company) or change companies because the current box is junk.

Answer 6

The two types of connections are not quite cross-compatible, although if connected this way you may successfully get a black and white image or no image at all.

The red, white and yellow cables are referred to as composite cables.  Although, the yellow is the only one that carries video - called CVBS for composite video blanking and sink.  A device that receives signal is referred to as a sink device - some people mistakenly call it sync.

The red cable in this cord is for right-side stereo audio and the white cable is for left-side stereo or mono audio.

The component red green and blue cables are different in that all three are dedicated to different parts of the video signal - audio is used separately.

In component the green cable is generally labelled Y which is apparently an old latin abbreviation equivalent to luminance - which is the picture brightness.  The red and blue are labelled Pr/Cr and Pb/Cb - which are Picture or Color minus red and blue.  The higher separation of signal generally the better the picture.

Component cables can actually carry up to 1080i at 60Hz or 1080p at lower framerates.

In your case, if your cable box was an HD box, you would have one or more of three ouputs based on the age and manufacturer of it.

1. Component

2. DVI-I/D

3. HDMI

If your box doesn't have this, then it's not an HD box.  Usually the only way to get component connections is to get and HD box even if your TV doesn't support HD resolution.  The difference in the picture quality should still be noticeable regardless.

As for picture quality on standard def televisions, the range goes from coaxial, CVBS (composite), Y/C (S-Video), and component (YPbPr,YCbCr,RGB).

Hope this helps.

Answer 7

You do not have an HD box. It is a stanard digital box. Ask your cable company for an HD box. You CANNOT get HD through composite video (yellow cable, the red and white are for audio) the composite yellow will have to be replaced with the component (R/G/B cables) cable so you will have 5 cables all together, R/G/B + R/W. At the risk of confusing the issue even further you can use HDMI connection to replace all 5 cable on the current HD boxes. There are currently NO HD cable boxes that don't have component outputs although in the future you may see boxes that use only HDMI.

Answer 8

Are you sure the HD box is an HD box? Sounds like it's a standard box. What is the make and model number of the box?
