Method of detecting and synchronizing audio and video signals and audio/video detection and synchronization system

A system for detecting and synchronizing audio/video signals comprising:

• at least one microphone unit comprising:
• a microphone capsule configured to detect audio signals;
• an internal clock that continuously generates a time signal, wherein timestamps are generated from the time signal, the timestamps containing the moment in time at which the respective timestamp is generated;
• a memory configured to store the detected audio signals and the associated timestamps;
• and
• an optical signal emitter that outputs an optical synchronization signal that contains optical timestamps associated with a respective one of the generated timestamps;
• and
• at least one camera unit comprising:
• a controller configured to extract optical timestamps from a detected video signal and to synchronize the detected video signal with an audio signal that is detected by an external microphone unit and which has timestamps, with which a respective one of the optical timestamps is associated, on the basis of the optical timestamps or light pulses and the timestamps in the audio signal;
• wherein the system is configured to extract the optical timestamps contained in the optical synchronization signal and to synchronize the video signal and the audio signal based on the timestamps in the audio signal and the optical timestamps extracted from the detected optical synchronization signal.
