Description of the Related Art Conventionally, there is a Video-CD described in Nikkei Electronics (November 8, 1993) as a method of storing a data program interactively corresponding to a user operation. This Video-CD records video data such as moving images and still images, and audio data such as music and sound effects, and plays back this video data and audio data, and is information that is controlled in response to user operations. The control data is also recorded at the same time.

As a method of acquiring and reproducing interactive data programs from a network server, a WWW (World Wide Web) server on the Internet has
The access method using a viewer is widely used.

[0004] Video-CD playback control data is also used in HTML (Hyper T), which is a data structure used in WWW servers and browsers.
ext Markup Language) is also link structure data composed of a node for displaying multimedia information such as text, graphics, and images to a user and a link pointer capable of instructing movement to reference information related to the displayed node. Link structure data is a data structure that implements hypertext information.

In data access using a Video-CD or other local storage media, since the transfer speed between the storage medium and the playback device is relatively high, high-capacity data represented by moving images can be accessed at a high speed. Becomes On the other hand, the storage medium itself must be physically sent to the user from the distributor, such as by mail, and the immediacy or data update period requires more time than the storage medium creation time and mailing time, and is frequently changed. Not generally suitable for modern data distribution.

On the other hand, in the network server, the server and the playback device are connected at the time of playback, and the data is acquired. Therefore, the immediacy and the data update period are generally quick, and the latest data can be distributed. On the other hand, the data transfer speed of a network is usually lower than that of local access, and is not suitable for transferring a large amount of data such as a moving image at a high speed.

The operation of this embodiment will be described below with reference to FIG. When the interactive video reproducing apparatus 101 acquires the node information of the link structure data of FIG. 4A from the network server or the storage medium, the acquired link structure data is notified to the link structure data control unit 207. The link structure data control means 207 analyzes the node information. First, it is confirmed at 410 that the data is link structure data. At 420, node configuration information "centering"
Is specified and the node content information "MOVIE 100" is displayed.
Perform a line break. Next, the node content information “movie.mpg” moving image file is reproduced according to the designation of the node configuration information “embedded” syntax. Next, at 440, the designation of the node configuration information “embedded” is released. Next, at 450 and 460, the node content information "to the next page" is displayed as a link pointer referring to the link destination node information "page02.htm". Next, the node configuration information “centering designation” is released at 470, and then the node configuration information “link structure data” is released at 480.

The operation will be described according to the internal structure of the link structure data control means. For example, reference numeral 420 denotes a document structure analysis unit 502, which is decomposed into node structure information "centering" and "line feed" and node content information "MOVIE 100". The node display information generating means 505 centers and displays the character string "MOVIE 100" based on the node configuration information and the node content information, and performs a line feed. In 450 and 460, the link pointer detecting means 503 detects the link pointer and acquires “page02.htm” of the reference destination node.

By the operation of the link structure data control means 207, the display data shown in FIG. 8A is generated and displayed on the display means 209. When the link pointer 450 is designated by the input unit 204, the designated link pointer acquisition unit 507 specifies the link pointer, and the link destination node determination unit 506 determines that the link destination node has the node information “pa”.
ge02.htm ". Next, the link destination node information “pa
ge02.htm ”is requested to the node information obtaining unit 501, and the node information“ page02.htm ”is obtained. The acquired node information is displayed on the display unit 209 by the same processing. By the display / browsing process of the link structure data, the reference nodes designated by the user with the link pointer can be sequentially displayed.

Hereinafter, the validity period determining means 504 of the actual finger example will be described.
Will be described. FIG. 7 is an operation flowchart of the validity period determining unit 504 and the node display information generating unit 505. In FIG. 7, reference numerals 701 to 703 denote processes of the validity period determining means, and 704 and 705 denote processes of the node display information generating means. This processing is started when node information is updated, such as a user specification of a link pointer. In the process 701, the file "DISCINFO.T" specified by the predetermined hierarchical file structure position and the file name of the storage medium described in FIG.
XT "is read. “DISCINFO.TXT” has the media attribute information described in FIG. 603 is “Author” information indicating the creator of the storage medium, 604 is “Release Date” information indicating a distribution start date, 605 is “Title” information indicating title information, and 606 is “V” indicating version.
“ertion” information and 607 are “Valid” information indicating a validity period.

Get "Valid" information in the "XT" file. Next, in step 703, the current time is compared with the acquired “Valid” information, and it is determined whether the current time is within the validity period. If it is within the validity period, node information is displayed in step 704. If it is out of the validity period, the node information is changed (described later) in process 705, and the changed node information is stored in the memory 202. The stored node information after the change is transferred again from the node display information generation unit 505 to the node information acquisition unit 501, and the process 70
The node information changed in step 4 is displayed.

As an example of changing the node information in the process 705,
When the node configuration information “embedded” is detected, the link structure data within the start / end range of the node configuration information “embedded” is replaced with another link structure data. 431, 432, and 433 in FIG.
440 is an example of the replacement processing result. "Vali" indicating the validity period included in the media attribute information of the storage medium
According to the “d” information, the link structure data including the moving image information of FIG. 4A is converted into the link structure data to which the node change processing shown in FIG. 4B is applied.

As described above, according to the operation of the present embodiment, specific information (moving image data in the present embodiment) having a limited valid display period can be displayed only within the valid period. Further, the user can be notified that the moving image cannot be reproduced outside the valid period. As a result, fixed link structure data recorded on a non-rewritable storage medium such as a CD-ROM / DVD-ROM can be changed / changed according to specific media attribute information attached to the storage medium such as a validity period. Display becomes possible.

In this embodiment, the display data is directly output from the node display information generating means to the display means in FIG. 5, but the display data is output from the node display information generating means via the display control means. Configurations are also possible. Further, in the present embodiment, the configuration is such that the instruction information is directly notified from the input unit to the instruction link pointer acquisition unit, but a configuration in which the instruction information is notified from the input unit to the instruction link pointer acquisition unit via the input control unit is also possible. is there.

In this embodiment, the validity period in the media attribute information is used as a criterion. However, the media attribute information serving as a criterion is not limited to the validity period. For example, a configuration is also possible in which “Author” information is acquired as media attribute information, and a server on a network to be accessed is changed according to the “Author” information. This makes it possible to select a server to be accessed only by changing the “Author” information of the same storage medium.

Further, in this practical example, the link structure data is changed in accordance with the type of multimedia information specified by the node information such as moving image data, but the node information itself is set as a validity determination target. Other configurations are also possible, such as making only node information in a specific link structure data area a validity determination target. The type of information to be changed is not particularly limited to moving image data.

In this embodiment, the link structure data control means is realized by hardware. However, a part or all of the link structure data control means may be realized by software. The method of realizing the means is not particularly limited. In this embodiment, a single media attribute information is used as a criterion. However, a configuration in which a plurality of media attribute information or a combination of media attribute information and device attribute information is used as a criterion is also possible. This is not limited to a single piece of media attribute information. For example, a configuration in which a specific network server specified by the “Author” information is accessed only during the valid period according to the “Author” information and the “Valid” information is also possible.

In this embodiment, the media attribute information is set for each storage medium. However, a configuration in which the media attribute information is set for each directory of a certain hierarchy in the storage medium, or a configuration in which the media attribute information is set for each node information requiring the media attribute information. And the like, and the arrangement and number of the media attribute information and the information in the target storage medium are not particularly limited. In this embodiment, the link structure data stored in the storage medium reproduced by the interactive video reproducing apparatus is set as the validity determination target. However, the link structure data stored in the server connected via the network is set as the validity determination target. Configuration and
A configuration is also possible in which link structure data of both the storage medium and the server is set as a validity determination target, and the storage location of the link structure data of the validity determination target is not particularly limited.

In this embodiment, the validity determination means and the node display information generating means in the interactive video reproducing apparatus perform the validity determination and change the link structure data. However, the present invention is applied to a server connected via a network. It is also possible to provide an attribute information server acquiring means for acquiring a media attribute of a storage medium reproduced by the interactive video reproducing apparatus and a node display information server generating means, and a function realizing method of the attribute information acquiring means and the node display information generating means This is not particularly limited. When changing the link structure data on the server side, the interactive video playback device side receives the changed link structure data,
Display as it is.

Hereinafter, another embodiment of the present invention will be described with reference to FIGS.
3 will be described. FIG. 9 is a diagram showing a configuration example of device attribute information of this embodiment, FIG. 10 is a block diagram showing the configuration of link structure data control means of this embodiment, and FIG. 11 is a flowchart showing operations in the link structure data control means. FIG. 12 shows an example of changing the link structure data according to the device attribute information, and FIG. 13 shows a display result of the link structure data of FIG. The configuration and system configuration of the interactive video reproducing apparatus of the present embodiment are the same as those of the above-described embodiment. In FIG. 9, (a) is an example of device attribute information,
(b) is a configuration example of an application list showing a list of executable programs registered in the device, which is device attribute information, and (c) is one or more devices using the interactive video playback device, which is device attribute information. It is an example of personal information which is user information.

The operation of this embodiment will be described below with reference to FIGS. At the time of updating the node information of the link structure data, the screen resolution judging means acquires the screen resolution information 901 and 902 of FIG. 9A. In the node display information generating means 1002, the processing of FIG. 11 is started. FIG.
1101 and 1102 are processes of the screen resolution determining means 1001, 1103 to 1106 are node display information generating means 1
002. The process 1101 is started when link structure data is updated. In process 1101, device attribute information stored in the memory 202 of the interactive video playback device 101 is acquired. In process 1102, screen horizontal resolution information 901 in the device attribute information of FIG. 9A is acquired. Next, the processing of 1103 to 1106 is performed on each display line of the node information. In processing 1103, character information of display information is determined. If it is not character information, processing 1106
Execute If it is character information, the screen resolution obtained from the device attribute information (Player ID) in step 1104 is divided by the number of horizontal dots of the designated font to be used for display, and the decimal point is truncated (not shown in FIG. 11). ) Get the integer value N. Next, in step 1105, node configuration information “new line” is newly added in units of N characters. FIG. 12A shows an example of the link structure data before the change, and FIG.
An example of the link structure data after the execution of the link structure data change processing of the step 05 is shown below.

A screen resolution obtaining means 1001 which is attribute information obtaining means capable of obtaining device attribute information, and a node display capable of changing / adding / deleting link structure data according to the screen horizontal resolution obtained by the screen resolution obtaining means. The link structure data of FIG. 12A is changed to the link structure data of FIG. This processing is realized by adding the node configuration information “line feed” to the character string portion of the node information obtained by the processing 1104 every five characters.

FIG. 13 shows a display example of the link structure data of FIG. 12 by the node display information generating means. According to the present embodiment, link structure data stored in a medium such as a storage medium in which it is difficult to modify or delete the link structure data can also be changed according to the device attribute information of the interactive video playback device. For example, a storage medium having link structure data assuming a screen with a screen horizontal resolution of about 640 dots can be appropriately displayed on a small screen with a screen horizontal resolution of about 320 dots by line feed processing. Also, regarding the link structure data of the server via the network, it is possible to provide the link structure data according to the interactive video reproducing apparatus that performs the link structure data.

As described above, in the present embodiment, the processing is performed on the assumption that the number of horizontal dots of the font at one node is uniformly fixed. However, processing and configuration corresponding to multi-font can be performed. The method of calculating the number of characters is not particularly limited. Further, the character information to be changed in the node can be changed in the number of vertical display lines of the paragraph in addition to the number of horizontal characters in one line, and the method of changing the node information is not particularly limited. Further, a moving image / still image other than character information can be changed, and the change target information is not particularly limited.
Accordingly, for example, it is possible to have displayable color number information in the device attribute information and selectively display a plurality of prepared image information according to the number of colors to be displayed according to the color number information.

In this embodiment, the screen resolution is used as the device attribute information. However, other information such as an application list or personal information can be used as a determination material. The attribute information is not particularly limited. Furthermore, it is also possible to make a judgment configuration in which the above-described media attribute information is considered in addition to the device attribute information, and the attribute information is not particularly limited to the device attribute information.
Further, in this embodiment, the attribute information acquiring means and the node display information generating means are provided in the interactive reproducing apparatus. However, at least one of the attribute information acquiring means and the node display information generating means is provided by a server connected via a network. A configuration for performing the execution is also possible, and the mounting positions of the attribute information acquisition unit and the node display information generation unit are not particularly limited. In this embodiment, the link structure data control means is realized by hardware. However, a configuration in which part or all of the link structure data control means is realized by software is also possible. The method does not particularly limit this.

As described above, in the present embodiment, the method of displaying and browsing the link structure data is changed by using the media attribute information and the device attribute information. A configuration is also possible in which the display and browsing of the link structure data is changed according to other classification attributes such as service attribute information classified as contents. According to this, for example, for each node information, a list of information providers related to the node information is used as service attribute information, and the information provider list of the service attribute information is stored and stored every time a user accesses the node. By doing so, it becomes possible to change the link structure data according to the access frequency for each information provider that the stored user has accessed in the past. By using this configuration, for example, in a storage medium that provides product information, the history of the information provider (maker) is recorded for each node accessed by the user, and the history related to the information provider accessed by the user more than a specified number of times is recorded. Additional information not normally displayed in node information (limited information)
Can be displayed.
