I drive a video feed through a coaxial cable?

I have a station set up with a computure MDEIE, DVD, and a secondary competition all connected to a switch from the media goes to the projector. What I do is carry this channel video switching media through cpax line to be able to connect the TV is an example to food. What I have to translate this food to push though a 300 feet. line coaxial?

My first suggestion would be to use a coaxial cable. Go digital, then you should not have to worry about any resistance from the line. 300 feet away is a serious problem.
