RF Modulator (Option)
The RF modulator takes the mono audio and CVBS video internally generated by the STB, converts
them to an UHF channel selected by the user and then adds this channel to all terrestrial channels
coming in from the terrestrial antenna. That is, the RF modulator outputs all terrestrial channels
where the STB generated CVBS and mono audio becomes one channel within the UHF channels 21
