ABSTRACT:
A method and apparatus for signal transmission in which each of a series of input signals (e.g., RGB baseband video signals) is frequency-modulated onto an intermediate frequency. The intermediate frequency signals thus produced are then fed through RF mixers and frequency-shifted to an assigned transmission channel. Each channel is then RF multiplexed into a composite signal for providing a complete set of input signals to one or more monitors. Each monitor is provided with a splitter to divide the composite multiplexed signal into its RF components, which are fed to RF mixers to be shifted back to intermediate frequency signals. Demodulators convert these intermediate frequency signals to output signals corresponding to the input signals.
