Problems solved by technology

[0007] In addition to bit rate issues, remote decoding of video signals has other disadvantages: the repeated display of non-progressive scan images in this configuration may cause a wobbling effect during display if the repeated images contain moving objects
However, these complete frames, constructed from interlaced fields, will also be displayed in an alternating manner, creating the possibility of wiggling artifacts

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 receiving a trick mode command and selectively inserting 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. 119(e) to provisional application Serial No. 60 / 334,914, filed October 23, 2001. technical field [0003] The aspects of the present invention relate generally to video systems, and more particularly to video systems for recording or playing back digitally encoded video sequences. Background technique [0004] In today's home appliance market, digital television (DTV) and high-definition television (HDTV) are gaining popularity. Many purchasers of such televisions also purchase digital video recorders or players, such as digital video disc (DVD) recorders or players, in order to watch previously recorded programs or to record their favorite programs. In particular, a combination of DTV (or HDTV) and digital video recorder or player may be an integral part of a home theater entertainment system. [0005] A digital video recorder or player typically includes a Moving Pic...
