REVERSE TRICK MODES ON PROGRESSIVE VIDEO USING SPECIAL GROUPS OF PICTURES |
摘要 |
<p>The invention concerns a method (200) and system (100) for encoding a video signal. The method includes the steps of receiving (212) a progressive video signal and encoding (214) the progressive video signal into at least one group of pictures having at least one prediction source picture and at least one non-prediction source picture. All the non-prediction source pictures are predicted from the prediction source picture such that no non-prediction source picture is predicted from another non-prediction source picture. The method also includes the step of, in response to a reverse trick mode command, altering (218) the display order of the group of pictures to permit the group of pictures to be displayed in a reverse order. Additionally, the method can include the step of modifying (220) at least the number of non-prediction source pictures in the group of pictures in response to the reverse trick mode command.</p> |
