Analogue-digital video converter

Postby Marp » Sat Feb 16, 2013 4:19 pm


I'm new to the forum and new to "techy" DIY, although I have been making things out of randomly salvaged stuff for years. I can use a soldering iron and have a very basic knowledge of electrical circuits.

I have been given a digital satellite box that I want to plug into an existing system that presently comprises an internet TV decoder linked to an LG monitor using an HDMI lead. The problem is the LG monitor only has digital inputs - HDMI, D-Sub and VGA, while the sat box only has RGB and SCART out. I've been told there's no way to directly connect the two without an analogue-digital converter. (I can't plug the sat box into the monitor via the TV decoder because the analogue and digital circuits in the TV decoder are separate.)

Being close to my wallet, I don't want to shell out 75 quid (or more) to plug a sat box I got free into a monitor I got free. Is there any cheaper way to build an adc that can be used for the purpose? Alternatively, is there anything I might be able to cannibalize to the same end?

Thanks for any suggestions you may have.

I'd love to work on a converter but as has been pointed out a cable for £4 will do it quite well! I think an HDMI to VGA would be quite desirable for the upcoming educational version of the Raspberry Pi, as well as PS2 to USB converters. That way schools can use their old tech with the new!
