Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital data broadcast having an interactive function, for example, displaying information desired to be obtained, such as watching detailed information of a player while watching a sports broadcast, as a character string, or using a hyperlink in the WWW. The present invention relates to an information duplication device and a duplication method that support creation of content that realizes an interactive function of digital data broadcasting in which a user can execute switching of a display screen or the like by setting a similar link.

[0002]

2. Description of the Related Art Recent advances in moving picture compression technology have led to digitization of television programs that have been conventionally broadcast in analog form. According to the MPEG standard, in addition to moving images and audio, which are digital video information, other data can be multiplexed as user-defined area data, for example, private section data. Many attempts have been made to multiplex and broadcast various types of additional information using this fact.

[0003] A typical example of the additional information is on-screen display graphics (OSD). This makes it possible to superimpose and display a character string and a bitmap on a video. Thereby, depending on the definition of the link information indicating the relationship between arbitrary information units among the information units constituting the information, a commentary of the video scene is displayed, and
The change of the control information of the SD and the movement of the scenes constituting the program can be realized at a time desired by the user.

[0004] When receiving a digital data broadcasting service, a television is used to display a received image, and when using an interactive function, a remote controller of a digital data broadcasting receiver is generally used. . The components of digital data broadcast content include still images, moving images, audio, buttons, and LUs that represent color information.
T and the like. Control information for realizing the interactive function includes focus destination information for moving the focus indicating which button is selected, link information for calling one content to another content and switching the display, Instruction information, such as bytecode, for enabling a program to be executed is set, and these are set as attribute values of buttons and scene objects. In content authoring of digital data broadcasting, an interface specified according to an object is prepared to simplify the content editing work. When the interface is specified, there are many editing operations in which similar settings are made and only a part of the interface is rewritten, so that the editing operation of duplication is often performed.

There is WWW typified by the Internet as a service for enjoying an interactive function which is widely used at present. In the WWW, display can be switched by calling another content from one content using a hyperlink. In the authoring tool of the WWW browser that provides that function, the object is duplicated as it is while retaining the link information of the attribute of the object that defines the relationship between the currently displayed content and the content that you want to switch display from now on What can be done now exists.

[0006]

However, even if the link information indicates a non-existent link destination, if the object for which the link information indicates a non-existent link destination is duplicated, the existing WWW browser's authoring tool generates a duplicated object. Is copied as the attribute value up to the link information which is the attribute value of the copy source object. When trying to obtain information from a hyperlink destination by performing such editing, a problem occurs because an attempt is made to access a link destination that does not actually exist.

[0007] When the above-mentioned trouble occurs in the data broadcasting service, it is conceivable that the data broadcasting service becomes unavailable or unstable due to the absence of a reference destination.

In order to reduce editing errors and to perform authoring efficiently even when creating digital data broadcasting contents, an information copying apparatus and a copying method having a copying function for eliminating a problem such as an unknown link destination. is necessary.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an object which is an attribute of an object according to an attribute value of the object to be duplicated at the time of a duplication process and a state of the object related to the attribute value. Duplicate processing is performed by changing the dependent attribute value. First, an object is selected to specify which object is to be subjected to the duplication processing. The selection of the object is performed by the object selecting means. As a result of the selection, there is a case where the object to be duplicated is one object and another object related to the object-dependent attribute value is not selected, and the case where the object to be duplicated is one object and the object-dependent attribute In the case where another object related to the value is also selected, there is a difference in the object-dependent attribute value to be copied by the object presence determination unit that determines whether the object exists. When the duplication processing is performed for the former case, the object existence determination unit determines that another object related to the object-dependent attribute value of a certain object is not selected, and the object is not selected from the copied objects. Clear dependent attribute values related to the object.
When the duplication process is performed for the latter case, the object existence determination unit determines that another object related to the object-dependent attribute value of a certain object is selected. Is retained.

This eliminates the problem of accessing an object that does not exist, reduces editing errors, and enables efficient authoring.
