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 th…
