First Claim
Patent Images
1. A recording medium having recorded thereon a video stream and a graphics stream, wherein:
- the graphics stream and the video stream are multiplexed and integrated into a digital stream;
the graphics stream (i) constitutes a menu to be overlaid with a moving picture obtained by decoding the video stream and (ii) includes one or more interactive control segment and an object definition segment defining a graphics object;
the interactive control segment includes a plurality of pieces of multi-page information and time information;
the time information includes a presentation time stamp, a selection timeout stamp, and a user timeout duration all of which are associated with a playback timeline of the video stream;
the presentation timestamp indicates a timing for displaying, as a current page, a first page of the menu;
the plurality of pieces of multi-page information include one or more pieces of button information;
the button information indicates information used to present a state of button material as a graphic object and to provide an interactive display composition on the page;
the button information includes a set-button-page command that instructs a playback apparatus to set, as a new current page, a page other than the current page when a state of a corresponding button material is changed to an activated state;
the selection timeout stamp indicates a timing for automatically activating a button material presented on the current page to cause the playback apparatus to execute the set-button-page command; and
the user timeout duration indicates a timing for resetting the current page to the first page so as to display the first page only.

Abstract
A playback apparatus, recording medium and method for providing a user interface control of video and audio media includes processing a graphics stream with one or more interactive control segments and an object definition segment of a graphics object. Multi-page information including button information and time information can present a graphics object in a state of button material and an interactive display composition as a menu display that can be transitioned in accordance with a reproduction processing of a video stream.
