BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a system configuration diagram according to an embodiment of the present invention. As shown in FIG. 1, a system according to an embodiment of the present invention includes a content handling device 1 (also referred to as a center device) that performs processing according to the present invention, a content providing device 2 that provides content, and a storage device that stores content. 3. A configuration in which a PC (personal computer) 4 such as a user's home is connected to the Internet 5. The user's mobile terminal 6 accesses the content handling device 1 via the Internet.
[0019]
Each of the content handling device 1, the content providing device 2, and the storage device 3 is realized by a computer and a program executed on the computer. Note that the storage device 3 is a storage device provided in a so-called storage service that provides a user with a data storage area. Note that the content handling device 1 and the storage device 3 may be the same device. Further, the storage device 3 may be a so-called home network server at the home of the user of the portable terminal 6 or the like. The mobile terminal 6 is, for example, a mobile phone, a PDA (personal digital assistant), or the like.
[0020]
The program in each of the above devices is recorded and stored on a computer-readable recording medium, for example, FD (Floppy (registered trademark) disk), MO, ROM, memory card, CD-ROM, DVD, removable disk, or the like. And can be distributed. Further, the program can be provided through a network such as the Internet or e-mail.
[0021]
The operation outline of the system shown in FIG. 1 will be described with reference to the sequence chart of FIG.
[0022]
First, the mobile terminal 6 accesses a Web page (hereinafter, referred to as a portal site) provided by the content handling apparatus 1 and requests a desired Web page provided by the content providing apparatus 2 from the portal site (step 1). Before requesting a desired Web page, information on the user (age, address, interest, etc.) and information on the storage area in the storage service used by the user may be registered as a service provided by the content handling apparatus 1. (Address, capacity, usable communication speed, etc.), and information (communication speed, etc.) regarding the user's PC 4 are input by the user from the portal site.
[0023]
The content handling apparatus 1 acquires a Web page from the content providing apparatus 2 in response to a Web page acquisition request from the mobile terminal 6 (Step 2). Then, meta information in the Web page is extracted, information about a content such as a moving image that cannot be displayed on the mobile terminal 6 is obtained from the meta information, and appropriate information is obtained by comparing the information with information about the storage area of the user. A content is selected (meta information processing: step 3).
[0024]
In this specification, “meta information” refers to “information describing matters relating to the acquired Web page itself, and information describing matters relating to contents included as links in the Web page”. .
[0025]
For example, a label Title in a file described according to Dublin core that defines a basic description element of meta information indicates a title of a Web page, and Creator indicates an author or an author. Also, there is an RDF (Resource Description Framework) specification for providing a standard framework for describing meta information.
[0026]
However, the above specifications and the like are defined to facilitate the use of the meta information, and even if they are not specially defined as described above, "the description about the acquired Web page itself is described. Information and information that describes matters related to content included as links in the Web page "are meta-information.
[0027]
Subsequent to the processing of step 3, the content handling apparatus 1 converts the contents of the Web page for display on the mobile terminal 6 (step 4). Then, a process of combining the information indicating the selected content and the converted Web page and rewriting the URL in the Web page is performed (step 5). Then, the combined Web page is transmitted to the portable terminal 6 (Step 6).
[0028]
The mobile terminal 6 displays, for example, an icon indicating that there is a content such as a moving image on the accessed Web page. When the user selects and clicks on information indicating the content, a save request is sent to the content handling apparatus 1. (Step 7). The content handling device 1 obtains the selected content from the content providing device 2 (this content providing device may be different from the content providing device that originally obtained the Web page) (step 8), and obtains the first obtained Web. After performing processing (step 9) such as storing link information and meta information relating to the page and the content in the database (step 9), the content is stored in the storage area of the user of the storage device (step 10).
[0029]
The storage area returns a notification indicating the completion of storage of the content (step 10a). When a storage device that is not always operating, such as a server on a home network, is selected as a storage device, the content is temporarily stored in the content handling device 1 and the content is stored in the content handling device 1. You may be comprised so that transfer of content may be started at the stage where communication was ensured.
[0030]
Thereafter, the user can browse the stored list of contents by accessing the content handling apparatus 1 from the PC 4 (step 11), and the user can select a desired content from the PC 4 to select the desired content. Can be obtained (step 12).
[0031]
FIG. 3 is a diagram showing in detail the functional configuration of the content handling apparatus 1 and the transmission and reception of information with other apparatuses.
[0032]
As shown in FIG. 3, the content handling apparatus 1 includes a meta information processing function 11 for performing meta information processing on the acquired Web page, a URL rewriting processing function 12 for rewriting a URL in the Web page for transmission to the mobile terminal 6, A link information / meta information processing function 13 for recording information for a user to easily acquire the stored content in a link information database later, and save the content in response to a request from the link information database 14 and the PC 4. It has a Web page transmission function 16 for transmitting a Web page for selecting the placed content. The content conversion function 15 for converting the acquired Web page for display on a mobile terminal may be provided, but may be provided outside the content handling apparatus 1. Note that the link information database 14 may be provided outside the content handling apparatus 1 (for example, the storage apparatus 3).
[0033]
Next, the processing of the content handling apparatus 1 will be described in detail with reference to FIG.
[0034]
When a request for a desired Web page is transmitted from the mobile terminal 6 after the mobile terminal 6 accesses the portal site of the content handling apparatus 1, the content handling apparatus 1 sends the Web page request to the content providing apparatus 2. Transfer and acquire a Web page (steps 21 to 23).
[0035]
Next, the acquired Web page is analyzed by the meta information acquisition processing function 11 to acquire meta information. The meta information is as described above. For example, Web information is determined by a predetermined label (for an RDF file, dc: title, dc: identifier, dc: description, dc: type, dc: description, etc.). The title of the page, a keyword, a URL, a description of a Web page, a description of a content such as a moving image or audio (including a content capacity, a suitable communication speed, and the like), a content file name, and the like are obtained. The content such as a moving image or audio can be identified by, for example, an extension in the content file name.
[0036]
Then, using the acquired meta information, the content and the communication speed suitable for each content are compared with the information of the user's storage area, the appropriate content is selected, and the meta information related to the content is stored in a memory or the like. Keep it.
[0037]
Regarding the capacity, the content handling apparatus 1 compares the remaining capacity of the storage area and the capacity of the content, which have been notified in advance by the user. Alternatively, the content handling apparatus 1 itself may be configured to check the remaining capacity of the storage area for the user when the mobile terminal 6 receives the access.
[0038]
As for the communication speed, the value of the communication speed at the time of downloading in the storage service used by the user is compared with the communication speed suitable for the content. Further, the user notifies the content handling device 1 of the connection speed of the PC 4 to the Internet in advance, and the content handling device 1 compares the value of the communication speed with the value related to the communication speed for the content. Is also good.
[0039]
In this way, a content suitable for the user to browse from the PC 4 is selected. Selection of content can be performed using various conditions in addition to the above-mentioned capacity and communication speed. For example, if there is an age restriction on browsing the content, the content is grasped from the meta information, compared with the age registered by the user in advance, and when the age restriction is cleared, the content is selected. Further, it is also possible to pre-register a keyword in a field in which the user is interested, and to select the content when the meta information includes the keyword and other conditions are satisfied.
[0040]
Now, in the content handling apparatus 1, apart from the above processing, the content conversion function 15 converts the Web page for display on the portable terminal 6 (step 24). This conversion processing itself can be performed using a conventional technique. The content conversion function may be provided in the content handling apparatus 1 or may be provided in an external server or the like. If the external server has a content conversion function, the Web server transmits the Web page to the server, and receives the converted Web page from the server.
[0041]
Next, the URL rewriting processing function 12 combines the information of the content selected by the meta information processing function 11 with the converted information of the Web page, and rewrites the URL of the link in the page. That is, when the URL in the page is not rewritten, when the user selects the link on the mobile terminal 6, the user directly accesses the site of the link, so that the service provided by the content handling apparatus 1 cannot be received. Therefore, the link is rewritten so that the target site of the link destination can be accessed via the content handling device 1. Then, the combined Web page is transmitted to the portable terminal 6 (Step 25).
[0042]
On the mobile terminal 6 that has received the Web page subjected to the above processing, for example, the screens shown in FIGS. 4A and 4B are displayed. In the case of FIG. 4A, in the lower section of the converted Web page, contents such as moving images and audio related to the Web page are displayed as icons. This icon is an icon of an application for displaying a content such as a moving image and a sound. In the case of FIG. 4B, a content name such as a moving image and a sound related to the Web page and a list of the contents are displayed in a lower column of the converted Web page.
[0043]
When the user selects the content displayed on the screen of the mobile terminal 6, a request for storing the content in the storage is transmitted (step 26).
[0044]
Upon receiving the storage request, the content handling device 1 requests and acquires the content from the content providing device 2 that holds the content based on the content such as the URL included in the storage request (steps 27 and 28).
[0045]
The link information / meta information processing function 13 links information indicating the location of a storage area for storing the acquired content, the meta information already acquired by the meta information processing function 11, and the meta information newly acquired in the content acquisition. The information is stored in the link information database 14 (step 29). The meta information of the content stored in the link information database 14 is used as information for easily obtaining the content stored later from the storage. Then, the content is stored in a predetermined storage area (step 30).
[0046]
For example, information shown in FIG. 5 is stored in the link information database for each user. That is, for each Web page accessed by the user, the meta information of the Web page, one or more identifiers (for example, an address (file name) in the storage area) indicating the content related to the Web page, and the content The corresponding meta information is stored.
[0047]
The meta information corresponding to the Web page includes, for example, a title, an acquisition date and time, and a description of the content of the Web page. The meta information corresponding to the content includes a description of the content, an application for displaying the content, a file size, an appropriate line speed, and the like.
[0048]
Thereafter, when the user accesses the content handling apparatus 1 from the PC 4, the content handling apparatus 1 acquires information of the area corresponding to the user from the link information database 14 by the Web page transmission function 16, for example, as shown in FIG. The screen is displayed on the user's PC4. That is, since the above-described information shown in FIG. 5 is stored in the link information database 14, the screen shown in FIG. 6 can be displayed. As shown in FIG. 6, by displaying the meta information (eg, description of the content), desired content can be easily obtained.
[0049]
At this time, only the narrowed information may be displayed by, for example, prompting the user to specify a period for storing the content or inputting a keyword.
[0050]
Instead of storing the content itself in the storage, information on the access destination of the content may be stored, and the content may be acquired from the content providing device from the PC 4 via the content handling device.
[0051]
It should be noted that the present invention is not limited to the above-described embodiment, and various modifications and applications are possible within the scope of the claims.
[0052]
【The invention's effect】
As described above, according to the present invention, a user can easily access a wealth of information related to a Web page accessed from a mobile terminal, and can provide an information provider with information other than information for a mobile terminal. It is possible to provide users with an opportunity to provide a wealth of information.
