TRICK MODES USING NON-PROGRESSIVE DUMMY PREDICTIVE PICTURES

摘要

The invention concerns a method (200) and system (100) for performing a trick mode on a video signal containing a plurality of original pictures. The method includes the steps of receiving (212) a trick mode command and selectively inserting (216) at least one dummy predictive picture in the trick mode video signal using at least one prediction scheme among field-based prediction and frame-based prediction. In one arrangement, the selectively inserting step can include the step of selectively inserting at least a first dummy predictive picture in the video signal using field-based prediction and subsequent dummy predictive pictures in the trick mode video signal using frame-based prediction.
