ABSTRACT:
A system and method for monitoring direct broadcast satellite signals. In a most general embodiment, the invention (10) includes a mechanism (20) for receiving direct broadcast wireless signals encoded in accordance with a DSS transport protocol. The received signals are analyzed with respect to various parameters and an output is provided in response thereto. In a specific embodiment, the wireless signals are transmitted via satellite and plural integrated receiver decoders (20) are used, one with an associated channel, to receive the wireless signals and provide audio, video, program guide and conditional access signals in response thereto. These signals are analyzed by software (100) running on a computer (56) which outputs alarm data on the detection of anomalies in the received signals.
