Abstract
A signal distribution and control system where signals are distributed and control signals transmitted via a single coaxial cable. Integrated Receiver/Decoder (IRD) units communicate with a Frequency Translation Module (FTM) for construction of a custom data signal for delivery to all IRDs coupled to a given FTM. The commands sent by the IRDs to control the FTM inform the FTM which signals are of interest and should be placed on the custom data signal, also called the combined IRD channels. Previously installed IRDs that cannot generate the new commands are still supported in the system via legacy ports in the multiswitch.
