Abstract (en)
[origin: WO9952298A1] In digital video synchronisation, the trend in delay is monitored to enable a prediction to be made of the dropping or repeating of a video field. The audio time compression or expansion is then initiated a selected time interval in advance of the field the dropping or repeating. The loss of audio synchronisation can in this way be kept below perceptible thresholds.
