Digital television signal quality supervision having fault detection equipment generating input/output fault detection alarms and decision unit correlating/providing self sufficient alarm

摘要

The equipment supervision system has a fault detector equipment (DEq) detecting function faults (MFE) relative to equipment (Eq). There is a first fault filter (FE) generating equipment alarms (AE) in response to fault detection. There is a second fault filter (FV) generating forward alarms (ASV) from detected quality faults in the output signal. A decision unit (COR) generates a self sufficient alarm (AS) providing detected faults.
