Abstract
A method (200) of performing a trick mode on a video signal includes the steps of receiving (202) a trick mode command and repeating (204) a picture in the video signal to form a trick mode video signal in response to the trick mode command. If the picture being repeated is a bi-directional predictive picture, then the method can limit (210) the repeating step to a predetermined number of times.
Claims24
A method of performing a trick mode on a video signal, comprising the steps of:
- receiving a trick mode command;
- in response to the trick mode command, repeating a picture in the video signal to form a trick mode video signal;
- determining if the picture being repeated is a bi-directional predictive picture;
- and
- limiting the repeating step to a predetermined number of times if the picture being repeated is a bi-directional predictive picture.
A method of performing a trick mode on a video signal, comprising the steps of:
- receiving an advance trick mode command;
- in response to the advance trick mode command, repeating a bi-directional predictive picture in the video signal to form a trick mode video signal, wherein the bi-directional predictive picture contains a display indicator having a display indicator value;
- and
- setting the display indicator of the repeated bi-directional predictive picture to the display indicator value.
A system for performing a trick mode on a video signal, comprising:
- a controller for reading data from a storage medium and outputting the video signal;
- and
- a processor programmed to:
- receive a trick mode command;
- in response to the advance trick mode command, repeat a bi-directional picture of an original bi-directional picture in the video signal to form a trick mode video signal, wherein the picture contains a display indicator;
- and
- set the display indicator of the repeated picture in the trick mode video signal to a value for the original bi-directional picture.
A system for performing a trick mode on a video signal, comprising:
- a controller for reading data from a storage medium and outputting the video signal;
- and
- a processor programmed to:
- receive an advance trick mode command;
- in response to the advance trick mode command, repeat a bi-directional predictive picture in the video signal to form a trick mode video signal, wherein the picture contains a display indicator;
- limit the number of times the bi-directional predictive picture is repeated to a predetermined number of times.
