Abstract
The method and apparatus for reproducing data from a disk receives at least video data read from a disk such as a digital video disk or a digital versatile disk. At least a portion of the video data is then processed to produce image data such that different camera angle images are simultaneously displayed.
Claims45
A method of reproducing data from a disk, comprising the steps of:
- (a) receiving at least video data read from said disk, said received video data divided into a plurality of cells, each cell including video data associated with a different camera angle;
- (b) processing a portion of each cell in a number of said plurality of cells to produce image data such that different camera angle images are simultaneously displayed.
A method of reproducing data from a disk, comprising the steps of:
- (a) receiving at least video data and format information read from a disk, said received format information indicating a number of multiple camera angles represented by said received video data;
- (b) determining a number of camera angles which can be reproduced from the disk based on said received format information;
- (c) determining from user input whether the user has requested all possible camera angles or a subset thereof for simultaneous display;
- and
- (d) processing portions of said received video data to produce image data when said user input received in said step (c) indicates to display more than one camera angle image simultaneously.

A method of reproducing data from a disk, comprising the steps of:
- (a) receiving at least video data, audio data and format information read from a disk, said received format information indicating a number of multiple camera angles represented by said received video and audio data;
- (b) judging whether said disk stores video data and audio data associated with more than one camera angle image based on said received format information;
- (c) receiving user input requesting multiple camera angles for simultaneous display when said step (b) judges that said disk stores video data representing more than one camera angle image;
- (d) receiving user input which designates one of said camera angle images;
- (e) processing portions of said received video data to produce image data for multiple camera angles when said user input received in said step (c) indicates to display more than one camera angle image simultaneously;
- (f) processing portions of said received audio data associated with said designated camera angle image;
- and
- (g) outputting the audio data corresponding to the desired camera angle simultaneously with the simultaneous dispIlay of more than one camera angle image.

An apparatus for reproducing data from a disk, comprising:
- receiving means for receiving at least video data and audio data read from a disk;
- processing means for processing portions of said video data to produce image data such that different camera angle images are simultaneously displayed;
- a controller receiving user input which designates one of said camera angle images being simultaneously displayed, and controlling said processing means to produce said image data such that said designated camera angle image is displayed in a highlighted format and such that said audio data corresponding to said designated camera angle is simultaneously output.
An apparatus for reproducing data from a disk, comprising:
- a receiving unit to receive at least video data read from a disk, said video data being composed of a video object (VOB), which is part or all of an MPEG 2 program stream, said video object (VOB) being divided into one or more cells, each of which being a group of pictures, each cell divided into video object units (VOBU), each of which is an integer number of video fields, each video object unit (VOBU) being divided into video packs;
- a signal processor coupled to said receiving unit, processing a portion of each cell to produce image data such that different camera angle images are displayed simultaneously, said signal processor including,
- a video selector separating said portion of each cell,
- a single decoder decoding output from said video selector, and
- a synthesizer synthesizing output from said decoder to produce image data representing a synthesized image of said different camera angles;
- and
- a controller receiving user input indicating whether to display more than one camera angle image simultaneously, and controlling said signal processor to process said portion of each cell when said user input indicates to display more than one camera angle image simultaneously.
