IMPROVEMENTS RELATING TO AUDIO-VIDEO DELAY |
摘要 |
<p>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.</p> |
