Abstract

A method and system of collecting local television signals includes a local collection facility a plurality of primary receiver circuit modules comprising a first receiver circuit module. The first receiver circuit module receives and demodulates the first channel signal and forms an IP signal. A remote facility is spaced apart from the local collection facility and communicates with the local collection facility through an IP backhaul. A primary decoder within the remote facility is in communication with the IP backhaul and forms a decoded signal from the IP signal. A primary encoder within the remote facility in communication with the primary decoder forms a first encoded signal from the decoded signal. A multiplexer in the remote facility multiplexes the first encoded signal into a multiplexed signal. The multiplexed signal may provide an output signal used for uplinking or other type of distribution.
