Mixed format multipath signal consistency comparison system

The invention relates to a mixed-format multi-channel signal consistency comparison system. The system comprises a signal acquisition input device and a consistency comparison device which are connected with each other through a network communication protocol, wherein the signal acquisition input device is used for sending and acquiring fingerprints and technical review information; the consistency comparison device comprises a centralized control service module, a result display module and a configuration module. According to the invention, through comparison of multiple paths of signals, signal video and audio faults can be found in time, signal switching can be monitored and alarmed in real time, fault problem points can be rapidly and accurately positioned, and all-weather monitoring can be carried out on the whole broadcast link. The method is suitable for a plurality of scenes such as main and standby signal comparison, output signal and return signal comparison, studio source signal and output signal c
