Converter Box For TV?

I use to have an old TV that did not have Composite Inputs for DVD Players. So I bought a Converter Box. That allowed me to plug the Composite into the Box The Coax in the box and another Coax to run to TV.

Then to watch a Dvd all you had to do was select channel 3 and turn on the Dvd Player.

Now I was wondering if their is a Converter Box That will allow me to plug in Composite Cables in and Output Component Cables to the TV?

Any help is really appreciated…
