Abstract

A system and method suitable for collecting local television signals includes a local collection facility having a plurality of primary receiver circuit modules with a first receiver circuit module and a back-up receiver module. The local collection facility includes the first receiver circuit module receiving and demodulating the first channel signal and forming a first IP signal. The first receiver has a first multicast group. The back-up receiver circuit module receives and demodulates the first channel signal and forming a second signal. The back-up receiver has a second multicast group. 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 communication with the IP backhaul and forms a decoded signal from the first IP signal. The primary decoder belongs to the first multi-cast group. A primary encoder within the remote facility communicates with the primary decoder and forms a first encoded signal from the decoded signal. A multiplexer multiplexes the first encoded signal into a multiplexed signal. A monitoring system includes commanding the primary decoder to join the second multicast group and discontinue the first multicast group. The primary decoder forms the decoded signal from the second IP signal.
