Abstract

A method and apparatus for displaying different presentations of program material allows various presentations of a DVD movie, for example, to be displayed on a display for a user'"'"'s selection. The various presentations might involve different angles from which a user must select or different chapters from which a program should begin. The selection of a presentation is facilitated by displaying the various options on a single display such that the user can quickly choose which presentation to choose. Furthermore, audio is provided with chapter presentations to assist a user in selecting a chapter from where playback should be initiated.

Claims

1. An apparatus to play an audio/video datastream, said apparatus comprising:

an input to receive the audio and video datastream, said datastream comprising information for a plurality of different audio/video programs, wherein

each of the plurality of different audio/video programs comprises a video portion and an audio portion associated only with the video portion, and

each of the plurality of different audio/video programs is independently actionable by a user;

a decoding circuit configured to decode said datastream so as to output a signal for displaying a first presentation comprising a first video portion and a first audio portion associated with the first video portion;

a selection circuit operable to re-configure said decoding circuit such that said decoding circuit is configured to decode said datastream so as to output a signal for displaying a second presentation comprising a second video portion and a second audio portion associated with the second video portion concurrent with the displaying of the first presentation; and

a receiver configured to receive during use a signal from a user that directly selects which of said first or said second presentation is a desired presentation to display, wherein during the concurrent displaying of the first and the second presentations, the first audio portion and the second audio portions are concurrently output by the apparatus.

2. A method of selecting from a plurality of different audio/video programs each having a video portion and an associated audio portion, a desired presentation of the selected audio/video programs, said method comprising:

receiving a datastream comprising information for the plurality of different audio/video programs, wherein

each of the plurality of different audio/video programs comprises a video portion and an audio portion associated only with the video portion, and

each of the plurality of different audio/video programs is independently actionable by a user;

displaying on a display in normal playback mode a first selected audio video program comprising a first video portion and a first audio portion associated only with the first video portion;

displaying on said display in normal playback mode a second audio video program comprising a second video portion and a second audio portion associated only with the second video portion concurrent with the displaying of the first audio video program wherein during the concurrent displaying of the first and the second audio video programs, the first audio and the second audio portions are concurrently output; and

permitting a user to select directly either said first audio video program or said second audio video program.

3. The method as described in claim 2 wherein said displaying on a display in normal playback mode a segment of a first presentation comprises displaying a segment of said first audio video program for a predetermined period of time.

4. The method as described in claim 3 and further comprising displaying each selected audio video program on a different segment of said display.

5. The method as described in claim 3 and further comprising:

converting a portion of said first audio video program to a graphics format; and

displaying said graphics format on said display so as to represent said first audio video program while displaying on said display in normal playback mode said segment of said second audio video program.

6. The method as described in claim 5 and further comprising:

converting portions of all of said audio video programs to graphics format;

displaying all of said graphics formats on said display;

indicating to a user during use a particular one of said displayed audio video programs; and

allowing the user to select a preferred audio video program.

7. The method as described in claim 6 and wherein said indicating comprises:

cycling through each of said displayed audio video programs so as to indicate to the user each audio video program and so as to allow the user to select an audio video program when said presentation is indicated.

8. The method as described in claim 2 wherein said displaying of said second audio video program displays a segment of said video portion and associated audio portion that follows in time said segment of said video portion and associated audio portion displayed by said displaying of said first audio video program.

9. The method as described in claim 2 wherein said displaying of said second audio video program displays a segment of said video portion and associated audio portion that is contemporaneous in time with said segment of said video portion and associated audio portion displayed by said displaying of said first audio video program.

10. The method as described in claim 2 wherein said displaying of said second audio video program displays a segment of said video portion and associated audio portion that overlaps in time with said segment of said video portion and associated audio portion displayed by said displaying of said first audio video program.

11. The method as described in claim 2 wherein said datastream comprises video objects interleaved as blocks such that each interleaved block contains data for one of said plurality of different audio video programs.
