Abstract
The invention concerns a method and system for performing a trick mode in response to a trick mode command. The method 200 can include the steps of modifying a field display order indicator of at least one intra picture having at least a first field and a second field in a video signal containing intra pictures to enable the second field of the at least one intra picture to be displayed before the first field of the at least one intra picture and decoding the at least one modified intra picture. In one arrangement, the decoding step can be performed with a remote decoder, and the video signal can include non-intra pictures.
Claims18
A method of performing a trick mode, comprising the steps of:
- in response to a trick mode command, modifying a field display order indicator of at least one intra picture having at least a first field and a second field in a video signal containing intra pictures to enable the second field of the at least one intra picture to be displayed before the first field of the at least one intra picture;
- and decoding the at least one modified intra picture.
A system for performing a trick mode, comprising:
- a controller for reading data from a storage medium and outputting a video signal containing intra pictures, wherein the intra pictures contain at least a first field and a second field;
- a processor, wherein the processor is programmed to, in response to a trick mode command, modify a field display order indicator of at least one of the intra pictures in the video signal to enable the second field of the at least one intra picture to be displayed before the first field of the at least one intra picture;
- and
- a decoder for decoding the at least one modified intra picture.
