ABSTRACT:
The invention concerns a method (200, 300) 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 a trick mode command (212, 312) and selectively inserting (214, 324) at least one dummy bidirectional predictive picture in the video signal using field-based prediction to form a trick mode video signal. In one arrangement, each dummy bidirectional predictive picture can be a one-directional predicted picture, and the method can further include the step of predicting each dummy bidirectional predictive picture from a reference picture. In another arrangement, the predicting step can further include predicting each dummy bidirectional predictive picture from a single field associated with the reference picture.
