Description

  The present invention relates to a system for generating and distributing content for a portable information terminal.

  2. Description of the Related Art There is a strong demand for generating and distributing highly viewable and safe content in portable information terminals that are portable information devices such as mobile phones. Here, the content is a general term for text, images, moving images, multimedia content including them, and the like.

  There is a strong demand for browsing content for a personal computer using a mobile information terminal such as a mobile phone, and using content for a personal computer for content creation for a mobile information terminal.

  A portable information terminal has limited capabilities compared to a personal computer in terms of screen resolution, calculation capability, communication speed, power consumption, and the like, and there is a problem in browsing content for the personal computer on the portable information terminal.

  In creating content for a portable information terminal, it is necessary to consider the various restrictions described above, and it is generally not easy.

  The problem to be solved by the present invention is to realize a system for facilitating generation and distribution of content optimum for a portable information terminal.

Means for Solving the Problems and Effects of the Invention

  In order to solve the above-described problem, by using the content generation / distribution system including the steps according to claim 1, the content is generated in a format (for example, Flash) suitable for the target portable information terminal. Improve content browsing on mobile information terminals.

  When browsing content on a mobile information terminal, it is necessary to limit the volume of content to be delivered at a certain size or less depending on the effective use of bandwidth and the specifications of the mobile information terminal. Even in a situation where the content cannot be transmitted to the terminal, in order to display a large-capacity content in an enlarged manner, the dedicated content for the enlarged display is generated by the method according to claim 2 and displayed as necessary. It was decided to switch content.

  As means for realizing the safety of the content on the portable information terminal, the restriction condition of the content according to claim 3 is defined, and the restriction is obtained by checking the information obtained on the portable information terminal such as time and the restriction information as needed. By limiting the display time of content only when the condition is satisfied, the possibility of leakage of confidential information in the content is reduced by limiting the time when the content can be browsed.

  As means for realizing stricter safety on the portable information terminal, the validity period verification information is embedded in the content according to claim 4, and the validity period verification information is verified by the server as needed, By restricting availability, there is no possibility that information that cannot be used on the portable information terminal or false information can be obtained on the portable information terminal, so that confidential information in the content can be managed more strictly.

  In the case of managing a series of browsing of content as a session when browsing multiple contents on a portable information terminal, information for confirming the identity of the session is not available to the content generation / distribution side. When obtained on a terminal, the content session according to claim 5 can be used to check the content session even in an authentication environment based on a transparent reverse proxy by embedding a program for using session information in the content. Become.

  When managing a series of content browsing as a session in a plurality of content browsing on a portable information terminal, and when information for confirming the identity of the session is also obtained for the content generation / distribution side With the method of embedding session information and a program for using the session information in the content described in 6, it is possible to support various session takeover methods.

  Since it is troublesome for a user to create content in consideration of the capacity limitation inherent in the portable information terminal, the content according to claim 7 is divided into appropriate capacities, which are operated by a content viewer. The content is automatically converted into an appropriate state by a method of reconfiguration so that it is easy.

  When inputting information into content, in order to support various input formats such as character input, date input, check, and selection from multiple items such as menus, an input program suitable for it is required. By calling the necessary input screen described in item 8 as needed, it is possible to input in various input formats even on a portable information terminal with a limited communication capacity, and convenience for the viewer is enhanced.

  When it is necessary to change only a part of the content even after the content is distributed, it is possible to change the content by resending only a part of the distributed content by the method according to claim 9, and the viewer For both users and users, the amount of communication is reduced, so that timely information distribution can be realized with a small bandwidth and cost.

  In some cases, when it is desired to generate / distribute content by asynchronous communication such as e-mail, the content generation / distribution method using asynchronous communication such as e-mail according to claim 10 is used to take advantage of the characteristics of asynchronous communication, It is possible to widen the range of usage environments.

  In the layout creation step, the user 70 creates the layout 300 using the interface 12.

  The layout 300 includes a set of layout identification numbers, backgrounds, and frames (301 and 302 in the example). The layout identification number is information for uniquely identifying a layout, and it is assumed that different values are assigned to different layouts.

  The frames (301 and 302) are information for determining the position and size of the content in the mobile content. The layout identification information, the frame identification number, geometric information such as the position and shape, and the content Consists of standard values of types. The frame identification number is information for uniquely identifying a frame, and different values are assigned to different frames.

  In the background creation step, a background is determined, specifically, a background color, a background image, a frame, and the like are determined.

  In the frame editing step, an arbitrary number of frames (301 and 302) are defined.

  In the layout saving step, the layout is saved by the database 20 by electromagnetic means.

  The content editing step includes a card production step, a card storage step, and a card addition / deletion step.

  In the card editing step, the user uses the interface 12 to define card information.

  The card information is composed of a set of layout identification information, card identification information, and content information. The card identification number is information for uniquely identifying the cards 201 to 204, and different values are assigned to different frames.

  The content information includes frame identification information, content or a reference to the content, display control information, and link information.

  As the reference to the content, any information that can uniquely identify the content, such as a URI, may be used.

  The display control information includes a format, a degree of optimization processing, information necessary for enlargement / reduction display, and the like.

  The link information is a process executed when the user executes a predetermined procedure when the user browses the mobile content on the portable information terminal, and controls the display content on the mobile content, the mobile Invoking other content including content, starting a call, executing a program, and the like.

  In the card storage step, card information and content information are stored in the database 20.

  In the card addition / deletion step, stack information is added, changed, and deleted.

  The stack information includes stack identification information, a set of card information, and card order information.

  The card order information is a set of pairs of order information and card identification information. The order information includes information such as numerical values indicating the order of cards and a card name.

  The content composition step is executed by an instruction from the user via the interface 12 after the layout creation step and the content editing step.

  The content composition step is a step in which the stack information, the stack additional information, and the stack program are input and the mobile content 100 is output.

  The stack additional information is various information used for stack control, such as restriction conditions, valid period collation information, message update information, session information, and the like.

  The stack program includes an input reception program, a display control program, a link control program, a form control program, and a display restriction program.

  The mobile content 100 includes a standard display stack (110, 120, and 130), a zoom stack 140, and a form stack 150. In the content composition step, all of these stacks have display condition restrictions. And information for continuing a session and a program (hereinafter referred to as additional information) and the like are appropriately stored. However, unless otherwise specified, it is assumed that additional information is stored in these stacks.

  The standard display stack (110, 120, and 130) is composed of a plurality of cards (111, 112, 121, 122, 131, and 132), and is generated in the content composition step. By performing a predetermined operation on the portable information terminal on the standard display stack, one of the plurality of cards is displayed.

  When a card that can be enlarged and displayed, such as the card 111, is displayed on the portable information terminal 50, the enlargement / reduction display step is started by the viewer 80 performing a predetermined operation.

  In the enlargement / reduction display step, the zoom stack 140 is called via the network 60, and a predetermined operation is performed on the portable information terminal 50, whereby the content is enlarged / reduced and displayed.

  In the content synthesis step, in response to a request from the user, in order to update a part of the mobile content, the message management server 41 is inquired about the latest content, and an update program for displaying the latest content on the mobile content is embedded. .

  In the content synthesizing step, a program for controlling whether or not content can be displayed according to a predetermined mobile content display condition using information available from a portable information terminal such as time, etc., in response to a request from the user Embed in.

  In the content composition step, in the display restriction step, the display restriction management server 40 is inquired as to whether or not the mobile content can be displayed as valid period collation information, and a program for determining whether or not to display the mobile content depending on the availability is requested Embed in mobile content.

  In the content composition step, when information for maintaining the session is not given, the URL given to the mobile content is read from the _url variable of the Flash, etc., and the information available on the portable information terminal is used. Embed a program for executing a session continuation step for obtaining information for maintaining the session.

  In the content synthesizing step, when information for maintaining a session is given, a program for realizing the procedure necessary for executing the information and the session continuation step for maintaining the session is embedded in the mobile content.

  In the content composition step, a link for enlarging / reducing the content from the corresponding content in the standard display stack is embedded in the standard display stack. On the portable information terminal, a predetermined operation is performed in the standard stack. Thus, it is possible to call the zoom stack via the link.

  In the content composition step, if the input request is included in the request from the user, the input form selected by the user from the input form prepared in advance is generated and input to an appropriate place in the standard display stack. Generate a link to the form.

  The content composition step includes a division step and a reconfiguration step in order to divide the standard display stack into a predetermined capacity.

  In the dividing step, the standard display stack is divided into a predetermined capacity k (for example, 100 KB, etc.) in units of cards, and as a result, the standard display stack composed of N pieces of cards is divided into i-th stack. , N = N1 + N2 +... + Ni +... + NM (where the capacity of the stack i <k) is divided into M stacks.

When the transition from the (i + 1) -th stack to the i-th stack is made, it is natural that the last card of the i-th stack is displayed, but parameters cannot be passed to the generated stack later on the portable information terminal. If the initial display of the i-th stack is the first card in the i-th stack , there is no problem when transitioning from the (i−1) -th stack to the i-th stack , but the i + 1-th stack is the i-th stack. when a transition is made to stack the i-th stack first card of a appears unnatural, since hinder usability, in order to solve this problem, in the dividing step, the i-th stack initially 'generates a second of the stack, from the first card of the (i + 1) th stack i' i to display the last card to generate a link to the second of the stack And in, to realize that the transition from the first card of the (i + 1) -th stack i-th stack of the last card.

  In the dividing step, it is possible to display an arbitrary card as an initial state in response to a request from a viewer by generating a stack for displaying an arbitrary card of the i-th stack in an initial state.

  In the example of FIG. 2, the stack 200 is composed of four cards (201 to 204), and the card 201 (the cards 111 and 131 are cards having the same contents as the card 201) and the card 202 (the cards 112 and 132 are cards). 202, and a card 203 (card 121 is a card having the same content as the card 203) and a card 204 (card 122 is a card having the same content as the card 204), and stack 110, stack 120, Then, the stack 130 is generated, the card 110 is displayed in the initial state of the stack 110, the card 121 is displayed in the initial state, and the card 132 is displayed in the initial state of the stack 130.

  If parameters cannot be passed to the mobile content on the mobile information terminal, the process of regenerating the mobile content is omitted to display the initial value of the form input stack and the input value in the stack of the caller of the form input stack. Therefore, the session information of the mobile content and the content on the message server are linked after the form is input, and the input value is read into the mobile content using the message server and the session information described above.

  In the distribution step, the mobile content 21 is distributed from the content distribution server 30 to the portable information terminal 50 used by the viewer 71 via the reverse proxy server 31.

  When the reverse proxy server 31 does not exist, the content distribution server 30 performs distribution without going through the reverse proxy server 31.

  In the attached mail conversion step for generating content by means of asynchronous communication means such as mail, a dedicated mail address is given to the viewer 80, the mail address is read by the interface 12, processed, and returned by mail. Asynchronous processing is possible.
