H-bridge control circuit

this is what my next new project is:
I have an radio control set, which has a reciever for two servos. It is in a ship, so there will be one servo for steering, and one motor control circuit.
I want to make a circuit which will take the servo control signal as input, and use it to control an H-bridge from full-forward to full-backward.

I didn´t check the output of the reciever on a scope yet, but most probably it will have only cca 90° or less change on usual servo, so I need to convert it to get full control.
Maybe I should use some lowpass filter to get some average voltage, and the feed it to a PWM circuit?

Could someone help me with some easy idea how to do this?
