Remote monitoring system

摘要

A system for monitoring a selected channel signal included within a multiplex of channel signals and for transmitting a representation of the selected channel signal to a monitoring location is disclosed. The system includes a demultiplexer which receives the multiplex of channel signals and demultiplexes the selected channel signal in response to a channel select command. A transmitter unit receives the demultiplexed channel signal from the demultiplexer, compresses the demultiplexed channel signal, converts the compressed demultiplexed channel signal to a packet signal and transmits the packet signal to the monitoring location via a telecommunications link.
