Broadcast monitoring and control system

摘要

A system and method are disclosed for monitoring the quality of a broadcast. A broadcast signal is received at a receiver and the power of the received signal in a carrier band is measured. The power of the received signal in a sideband is also measured. A time is determined at which the ratio of the power of the received signal in the carrier band to the power of the received signal in the sideband is indicative of a carrier to noise ratio of the received signal at the receiver and the carrier to noise ratio of the received signal is stored at the receiver.
