TRICK MODE ON BIDIRECTIONAL PREDICTIVE FRAMES

摘要

A method (200) and system (100) for performing a trick mode on a video signal. The method includes the steps of receiving (210) a trick mode command, in response to the trick mode command, repeating (212) a picture in the video signal to form a trick mode video signal in which the picture contains a display indicator; setting (214) the display indicator of the picture being repeated to a predetermined value; and setting (216) the display indicators of subsequent repeated pictures of the picture being repeated to the predetermined value. In one arrangement, the trick mode can be a freeze trick mode, and the picture to be repeated can be a bidirectional predictive picture. In addition, the display indicator can be a temporal reference field having an integer value.
