Abstract
A focusing method and a focusing apparatus in an interactive mode, and a data storage medium are provided. The focusing method includes identifying a domain of a resource to which a focused element refers when a command to move a focus between focusing layers is input from a user, and moving the focus by converting the focus-moving command into a command appropriate for the identified domain, when the identified domain is not a mark-up document domain.
Claims21
A data storage medium comprising:
- AV data;
- and
- a mark-up document used for reproducing the AV data in an interactive mode,
- wherein the mark-up document is made using a focusing hierarchy structure so that a resource to which an element of the mark-up document refers and a domain that is different from that of the mark-up document can be navigated.
A focusing method in an interactive mode where AV data are reproduced using a mark-up document, comprising:
- identifying a domain of a resource to which a focused element refers when a command to move a focus between focusing layers is input from a user;
- and
- moving the focus by converting the focus-moving command into a command appropriate for the identified domain, when the identified domain is not a mark-up document domain.
A focusing method in an interactive mode where AV data are reproduced using a mark-up document, comprising:
- focusing on one of a plurality of mark-up document elements belonging to a top focusing layer;
- identifying a domain of resource to which the focused mark-up document element refers when a command to move a focus down to a first lower focusing layer is input from a user;
- and
- moving the focus by converting the focus-moving command into a command appropriate for the identified domain, when the identified domain is not a mark-up document domain.
A focusing method in an interactive mode where DVD-video data are reproduced using a mark-up document, comprising:
- focusing on an “OBJECT” element;
- identifying a resource to which the “OBJECT” element refers when a command to move a focus to a lower focusing layer is input from a user;
- and
- moving a highlight by converting the focus-moving command that is input from the user into a command to move a corresponding highlight defined in the DVD-video data.
An apparatus to reproduce AV data in an interactive mode using a mark-up document, comprising:
- an AV decoder to decode the AV data;
- a presentation engine to interpret the mark-up document;
- and
- a blender to blend the interpreted mark-up document and the decoded AV data,
- wherein when a command to move a focus between focusing layers is input from a user, the presentation engine identifies a domain of a resource to which a focused element refers and converts the focus-moving command that is input from the user into a command appropriate for the identified domain only when the identified domain is not a mark-up document domain.
An apparatus to reproduce AV data in an interactive mode using a mark-up document, comprising:
- an AV decoder to decode the AV data;
- a presentation engine to interpret the mark-up document;
- and
- a blender to blend the interpreted mark-up document and the decoded AV data,
- wherein the presentation engine comprises:
- an input unit to receive a command to move a focus between elements of a same focusing layer or between different focusing layers from a user input device;
- a focusing hierarchy information manager to provide focusing hierarchy information;
- a focusing manager to show elements that can be focused on in a current focusing layer, to convert the focus-moving command input from the user input device into an API command corresponding to a selected domain, to receive the focusing hierarchy information from the focusing hierarchy information manager so as to move a focus, and to perform a predetermined operation on a focused element when a perform command is input from the user input device;
- and
- an output unit to output interactive contents to the blender as a result of the operation of the focusing manager.
An apparatus for to reproduce DVD-video data in an interactive mode using a mark-up document, comprising:
- an AV decoder to decode the DVD-video data;
- a presentation engine to interpret the mark-up document;
- and
- a blender to blend the interpreted mark-up document and the decoded DVD-video data,
- wherein the presentation engine focuses on an “OBJECT” element, and when a command to move a focus down to a lower focusing layer is input from a user, the presentation engine identifies resource to which the “OBJECT” element refers, converts the focus-moving command that is input from the user into a command to move a highlight defined in the DVD-video data, and moves the highlight when the identified resource is the DVD-video data.
A focus-moving method, for navigating an object, which is embedded in a markup screen in an interactive mode, and which belongs to a domain other than a mark-up document domain, comprising:
- navigating the mark-up screen and elements included in the object embedded in the mark-up screen by moving a focus using a limited user input device.
