Description

Document distribution apparatus, distribution system, and distribution method

The present invention relates to a document distribution apparatus, distribution system, and distribution method for distributing the contents of a document to an access source terminal using a communication network such as the Internet.

A system in which documents described in various formats are stored in a storage on a communication network such as the Internet and can be viewed from an external terminal is widely known. According to this system, for example, a document created on an in-house personal computer can be viewed on a mobile terminal owned by the user regardless of location and time, which is convenient.

However, such a system cannot be browsed unless the viewing terminal has software for document playback (such as document editing software or a viewer). In order to solve this problem, it is known in Japanese Patent Application Laid-Open No. 2011-96079, Japanese Patent Application Laid-Open No. 2003-233525, and the like that document distribution software (hereinafter referred to as reproduction software) is distributed together with document distribution.

However, the playback software that can be used varies depending on the type of document and the type of terminal to be viewed. For this reason, the conventional document distribution system has a problem that it is necessary to own and manage a lot of reproduction software, which is expensive. Also, the terminal side has a problem that the number of types of playback software increases each time a document of a different type is browsed, resulting in insufficient memory capacity.

Furthermore, the conventional system has a problem that the display mode of the document differs depending on the reproduction software and the reproduction environment, and the layout of texts and diagrams changes variously. For example, when a document that can be used by multiple playback software is received, if the playback software that is different from the playback software that is normally used is distributed from the system side, even if the same document is played back, The display mode is different. Even if the same playback software is used, the display mode may differ depending on the playback environment, such as a difference in terminals to be played back or a difference in initial settings.

The object of the present invention is to allow various types of documents to be easily browsed without having to prepare various playback software on the terminal side, and to play back regardless of differences in the playback software and playback environment. An object of the present invention is to provide a document distribution apparatus, a document distribution system, and a document distribution method in which the display mode at the time does not change greatly.

The image generation unit converts a document requested to be browsed from the terminal into image data to generate a browsing image, and the image storage unit assigns and stores an access address to the browsing image generated by the image generation unit. Based on the browsing image to which the address for access is assigned, the file creation unit generates an HTML format browsing file including the address as one element, and the generated browsing file is viewed by the distribution unit as a terminal of the browsing request source. Delivered to.

The multi-page document is converted into a multi-page browsing image by the image generation unit, and a different address is assigned to each browsing image for each page and stored in the image storage unit. The file creation unit may create one browsing file including a plurality of elements corresponding to each address.

The file creation unit may create a browsing file that includes event handlers that define how to move between elements. The event handler may be described in a script language, and the script language may be Java (registered trademark) Script.

In addition, a determination unit that determines the type of the browsing request source terminal may be provided, and the image generation unit may generate a browsing image corresponding to the type of the browsing request source terminal. You may use what produces the file for browsing corresponding to the kind of terminal of a browsing request origin.

As the image generation unit, an image generation unit having a function of changing the resolution and size of the browsing image according to the type of the requesting terminal can be used. Furthermore, it is preferable to use a file creation unit that has a function of creating a browsing file including definition information that defines the arrangement position of the browsing image at the time of browsing according to the type of the terminal that requested the browsing. it can.

The document distribution system of the present invention includes the above-described document distribution apparatus, a storage connected to the document distribution apparatus via a communication network, and a portable terminal that requests browsing of the document, and the storage is a request for browsing. Various documents are stored.

The document distribution method of the present invention also includes an image generation step of generating a browsing image by converting a document requested to be browsed into image data, and an image storage for storing the browsing image with an access address. A file creation step for creating an HTML-format browsing file including the address as an element, and a distribution step for delivering the browsing file to a browsing requesting terminal.

According to the present invention, a browsing image obtained by converting a document into image data is generated and distributed as an HTML format browsing file with an access destination added to the browsing image. Versatile because it can be viewed in a browser without the need for software. In addition, it is not necessary to have a plurality of playback software on the document distribution side, and the operation cost can be reduced. Furthermore, since the document is converted into image data and distributed, the display mode does not change greatly depending on the terminal.

Furthermore, by distributing the document in the HTML format, a function dedicated for browsing the document (for example, a function for sending / returning the page when the button is pressed, a function for terminating the browsing, etc.) is used. It is convenient because a program or software with high versatility such as JavaScript can be used without requiring a program or software. In addition, it becomes possible to easily cope with such addition of functions and specification changes.

When the browsing file is generated in this way, the control unit 46 transmits the generated browsing file to the mobile terminal 12. When the browsing file is transmitted, a browser is activated on the mobile terminal 12 and a screen based on the browsing file is displayed on the display 22 as shown in FIG. In this example, a browsing image, a next button (tag), and a back button (tag) are displayed, and the page can be returned by selecting these next buttons and back buttons.

In this example, when the back button or the next button is selected, the file moves to the next or previous page. However, when the back button or the next button is selected, the next or previous page is displayed. You may move to the image (image for browsing). Of course, it is not limited to the selection of the back button or the next button, and it is possible to freely set what kind of operation or selection of the button (tag) actually causes the page to be forwarded or returned.

As described above, according to the document distribution system 10, since the document can be viewed with the browser of the mobile terminal, the document distribution apparatus and the mobile terminal do not need to have a plurality of reproduction software. In addition, since the document is converted into image data and distributed, it is possible to prevent a difference in display mode due to a difference in terminals to be browsed. Furthermore, by distributing the document in the HTML format, it is not necessary to use a dedicated program or software for realizing a function necessary for browsing the document such as page return.

In the present invention, it is only necessary to convert a document into image data and distribute an HTML file containing the image data as an element. Therefore, the detailed configuration is not limited to the above embodiment and can be changed as appropriate. For example, in the above-described embodiment, an example in which the storage and the document delivery apparatus are separate bodies has been described, but these may be provided integrally.

In the above-described embodiment, an example has been described in which the same processing is performed and a browsing image or a browsing file is created regardless of the type (model) of the mobile terminal, but the present invention is not limited thereto. It is not something. For example, the user's portable terminal and the model information of the portable terminal are registered in advance, and according to the model of the portable terminal so as to absorb the change of the display mode due to the difference in the model of the portable terminal on the playback side Processing may be performed to create a browsing image or a browsing file.

In this case, for example, the image size and resolution of the browsing image are determined in accordance with the screen size and resolution of the distribution-destination mobile terminal, or the display size and resolution of the image (viewing image) in the browsing file are determined. Can be considered. Further, the version of the HTML or script language used when creating the browsing file may be determined in accordance with the version of HTML or script language that can be used at the distribution destination terminal. Furthermore, the arrangement position of the image in the browsing file may be determined in accordance with the distribution destination terminal. Further, depending on the terminal of the delivery destination, the type of button or tag used at the time of browsing such as page return may be determined.

In the above embodiment, the document distribution apparatus transmits a document list to a mobile terminal, and the mobile terminal generates a document list based on the document list. However, the document distribution apparatus uses a document list. The list may be generated, and the list may be changed to a document list and transmitted to the portable terminal.

Furthermore, since the distribution form of the document list and list can be freely set, for example, after converting the document list and list into image data, the access URL to this image data is set as the source URL, as in the above-described document. An HTML format file may be created and sent to the mobile terminal. In this way, it is possible to prevent the problem that the display form of the document list and the list is different depending on the model of the mobile terminal of the distribution destination.

Also, by distributing the browsing file in the HTML format as in the present invention, as described above, it is possible to easily add or expand functions necessary for browsing such as page rewinding. When distributing, the browsing image is displayed as a thumbnail by performing a predetermined operation, and by selecting the browsing image displayed as a thumbnail, the selected browsing image is enlarged and added. May be. Of course, the user may be able to set addition and deletion of such functions.

In the above embodiment, the example has been described in which the generated browsing image is stored in the document distribution device, but the present invention is not limited to this. For example, the generated browsing image may be stored in the storage.

In the above-described embodiment, an example in which a document stored in a dedicated storage is distributed has been described. However, the present invention can also be implemented in a form that does not use a dedicated storage as described below. For example, if application software for using the document distribution device 16 is installed in advance on a mobile terminal and the file to be viewed when browsing the Internet on the mobile terminal requires dedicated playback software, Start application software automatically. Thus, the file to be browsed (or the URL for accessing the file) may be transmitted to the document distribution device 16. Thereafter, the file to be browsed is converted into image data by the document distribution device 16 and a browsing image is generated. Similarly, an HTML browsing file including the browsing image is generated and generated. The browsing file is distributed to the mobile terminal. As a result, even files and documents that require dedicated playback software can be viewed without dedicated playback software.
