computer to dvd

[imkool]

I have a computer with a graphics card that has a s video port that also supplied me with a s video to Y-Pr-Pb cable as well. i also have a old tv with only a video and audio input. I want to connect my pc to tv and have 2 uncertainty's i need to clarify if u could help it would b appreciated.

1. I don't know if Y-Pr-Pb supports audio or not. From what i read and understood, the 3 Y-Pr-Pb only have something to do with color display.

2. Can i connect a Y-Pr-Pb to my old tv that has video and audio inputs (i think they are called rca inputs) since it doesn't have Y-Pr-Pb inputs?

1. It doesn't - strictly video

2. No. You *might* be able to get a converter that will let you convert the component video down to composite over RCA.

You need to take your audio from your headphone jack to the TV. You will probably need a 3.5mm jack to RCA cable - stereo if your TV has stereo inputs.

Hi!

In last few months I develop an YPbPr add-in card for existing TV sets that are with only composite video input.
I have almost ready PCB project and remain to submit it to any PCB fab house, to solder components and to test it.
To use such add-in card, the TV set must be with chroma processor with external baseband chroma delay line - in my case ICs TDA8362 and TDA4661.
The TV set will operate as usually in TV mode, receiving an analogue broadcasts.
In A/V mode, when connect a composite video source to the existing composite video input all will be as usually - it will works as before.
But, when we have connected a component video source with Y cable on the allready existing composite video input (that is combined CVBS/Y input yet), and the Pb and Pr cables on the additionaly mounted two RCA jacks, we will watching a colour picture without cross-color artifacts.

Say does that mean VGA and DVi cables dont have audio as well?
is there any way to get audio from pc to the tv as well?

Only HDMI carries audio and video together. VGA, Composite, DVI etc are video only. As I poinyed out in my post (above)

You need to take your audio from your headphone jack to the TV. You will probably need a 3.5mm jack to RCA cable - stereo if your TV has stereo inputs.

Were you supplied with a TV-Out to s-Video cable? A normal S-Video cable or adapter usually matches pins 1-4 on the TV-Out connector. S-Video to composite is a simple sum, Adapters are availalble or you can make one.

than what about the s-video to 3 RCA. Doesnt that have audio and video? if it does than wouldn't it be better to just get one to those?

s-video to three RCA would be s-video to component. s-video does not carry audio.

Standard S-Video connector (4pin)


All "TV Out" connectors have S-video on pins 1-4 and that is where commonality stops. There are 7 and 9 pin "TV Out" connectors that are proprietary to each display card or projector or other device manufacturer and come in maybe a half dozen variations. YOU NEED TO CONSULT YOUR MANUAL OR MANUFACTURER WEB SITE for pinout.
The big clue is to look at the adapter cable the display card manufacturer packed with your product.

Some projectors put audio on pins 5-9. Display cards with the exception of HDMI cards have no audio capability. So if you find a 7 or 9 pin DIN to Yellow-Red-White RCA cable, it was probably made for a projector or other custom hardware product.

Some older ATI cards placed composite video on pin 6 of a 7 pin tvout connector. Other hardware makers put RGB on pins 5,6,7.


ATI All in Wonder and other tuner cards used a similar 7 pin connector for S-Video, composite and audio inputs to the card.


Current NVidia cards (but not all) now use a 9 pin "TV out" connector that adds analog component YPbPr to the extra pins and the ship an adapter that looks like this. My Compaq laptop shipped with an NVidia Go chipset that supports a similar connector.



Should I go on with all the exceptions and special cases? Point is YOU need to research your card.
