Fast motion trick mode using non-progressive dummy predictive pictures
Abstract:
The invention concerns a method and system for performing a trick mode on a video signal containing a plurality of original pictures. The method includes the steps of selectively skipping at least one of the original pictures to convert the video signal to a trick mode video signal in response to a trick mode command and selectively inserting at least one dummy predictive picture in the trick mode video signal using field-based prediction. The method can also include the steps of monitoring the trick mode video signal in which the step of selectively inserting at least one dummy predictive picture in the trick mode video signal can be done if the bit rate of the trick mode video signal exceeds a predetermined threshold.
