Aufdecken und Verdecken von Fehlern für serielle digitale Videodatensignale

摘要

A method of detecting bit errors in serial digital video uses a digital demodulator to process a parallel video data signal derived from the serial digital video. The output of the demodulator is converted to analog, lowpass filtered, squared and compared with a threshold value. The result of the comparison produces an error signal when bit errors occur. The bit errors may be counted over a predetermined time period, may be used to switch a data filter into the video data output path to conceal the bit errors, and may be used to map the bit errors to a display for visualization of the location of the errors within a video image represented by the serial digital video.
