Peter,

If the TV you intend to use has a composite video input then you can
directly use an on screen display board which will either generate its
own video signal or overlay the text onto the video signal from a
camera. If the TV does not have a composite video input then you will
need a modulator to convert the composite video signal to an RF signal
that can be connected to the TV's aerial socket.

I suggest you visit http://www.stv5730a.co.uk and have a look at the
16F84/628 on screen display project board.

Kayode.
