Fast motion trick mode using dummy predictive pictures

In a remote decoder arrangement, a method of performing a trick mode on a video signal containing a plurality of progressively scanned original pictures, wherein each of the plurality of progressively scanned original pictures contains a display indicator, comprising the steps of:

• in response to a trick mode command, selectively skipping at least one of the original pictures to convert the video signal to a trick mode video signal;
• monitoring a bit rate of the trick mode video signal;
• selectively inserting at least one dummy predictive picture in the trick mode video signal if the bit rate exceeds a predetermined threshold;
• and
• selectively modifying the display indicator of at least a portion of the plurality of original pictures to reflect an intended display order when an original picture is repeated or when a dummy predictive picture is inserted in the trick mode video signal.

A system for performing a trick mode on a video signal containing a plurality of progressively scanned original pictures, comprising

• a controller for reading data from a storage medium and outputting the video signal containing the plurality of original pictures;
• and
• a video processor, wherein the processor is programmed to:
• in response to a trick mode command, selectively skip at least one of the original pictures to convert the video signal to a trick mode video signal;
• monitor the trick mode video signal;
• and
• selectively insert at least one dummy predictive picture in the trick mode video signal if the bit rate of the trick mode video signal exceeds a predetermined threshold.
