You have spare RF Channels !!!!!

There is a black box available from CPC http://www.cpc.co.uk called the EZ
Wideband Modulator that does what you want. takes baseband video and audio
and puts it out on a TV Channel that is selected by a push button.
Presumably there is a version available at your location.

Look for a faulty Video Recorder with a Modulator that can be tuned across
the whole UHF TV Band. The synthesiser in these modulators tend to be
controlled by a serial interface such as  I2C so if you go down this path
you end up with a PIC project.
