  According to the present invention, it is possible to provide a portable information terminal, a control method, and a program for appropriately performing content reception processing using, for example, RSS information while reducing power consumption and effectively using storage.

  The best mode for carrying out the present invention (hereinafter simply referred to as an embodiment) will be described below in detail with reference to the drawings.

  FIG. 1 shows and describes the configuration of a portable information terminal according to an embodiment of the present invention.

  As shown in FIG. 1, a central processing unit (CPU) 1 that controls the entire system communicates with a random access memory (RAM) 4, a flash memory 5, and a read only memory (ROM) 6 via a control bus 21. Connected freely. The ROM 6 stores a control program in advance, and the CPU 1 reads the control program from the ROM 6 and executes it. At this time, the RAM 4 functions as a work area. The flash memory 5 stores data such as various contents such as music and images. Note that a hard disk may be employed instead of the flash memory 5.

  The CPU 1 via the control bus 21 from the media driver 2 that controls writing / reading on the recording medium 3, the communication I / F 7 that outputs the communication data from the wireless communication module 8 through serial / parallel conversion, and the microphone 13. Is also connected to a voice input / output control unit 12 for controlling voice input and voice output via the speaker 14 and a key I / F 15 for outputting a signal corresponding to the operation of the operation input unit 16 conceptually including a QWERTY keyboard and various buttons. Has been. The CPU 11 is also connected via a control bus 21 to an LCD driver 17 that drives and controls the LCD 18 and a touch panel controller 19 that outputs a signal when the touch panel 20 is operated. The LCD 18 and the touch panel 20 constitute a touch screen. In addition, the power from the power supply circuit 10 including the battery 11 is configured to be supplied to each unit by the power supply circuit 9. The power supply circuit 10 supplies power from the AC power supply when connected to an external AC power supply.

  In such a configuration, when a power button conceptually included in the operation input unit 16 is turned on, power is supplied from the power supply circuit 10 to each unit via the power supply circuit 9. Then, CPU1 starts control of each part by reading the control program of ROM6 and executing it.

  When the CPU 1 operates based on this control program, it functions as a control unit, for example. That is, the CPU 1 functions as a control unit, and automatically connects to an external network at a predetermined time via the communication I / F 7 and the wireless communication module 8 as a communication unit, and acquires updated content. The communication unit is controlled, and after the updated content is acquired, the communication unit is controlled to automatically disconnect from the network.

  Further, the CPU 1 drives and controls the LCD 18 as a display unit via the LCD driver 17 and displays a menu screen (initial screen) on the LCD 18. In the menu screen (initial screen) displayed on the LCD 25, “Network Setting” for setting various networks, “Audio Player” for playing music, etc., “Web Browser” for browsing web contents, and RSS are distributed. Various applications such as “RSS Reader” for browsing content can be appropriately selected.

  In particular, when “Network Setting” is selected, as a first mode in which connection to the network is tapped on the screen, the connection is made to the network as necessary, and when a predetermined termination condition is satisfied, the first mode is established. It is possible to arbitrarily switch between an on-demand mode and an always-on mode as a second mode that is always connected to the network.

  Whether the connection to the AC power supply is possible or not can be determined by the CPU 1 based on the status signal from the power supply circuit 9. Further, the remaining amount of the battery 11 can be determined by the CPU 1 based on the state signal from the power supply circuit 9. Therefore, the mode setting in this case can be performed by the CPU 1 based on the state signal.

  When reproducing still image data based on an instruction by a user through an operation input on the touch panel 20 or the like, the CPU 11 stores still image data compressed and encoded by JPEG (Joint Photographic Coding Experts Group) or the like in the flash memory 5 or After reading from the recording medium 3 and decoding by software processing, the LCD driver 17 drives and controls the LCD 18 to reproduce a still image. In addition, when reproducing moving image data based on an instruction by a user through an operation input on the touch panel 20 or the like, the CPU 11 stores the moving image data compressed and encoded by MPEG (Motion Picture Experts Group) or the like in the flash memory 5 or the recording medium. 3 and decoded by software processing, the LCD driver 17 drives and controls the LCD 18 to reproduce the moving image.

  On the other hand, when “RSS Reader” is tapped by operating the touch panel 27, it becomes possible to appropriately select and browse the title of the updated content.

  Here, “RSS” refers to an XML-based format in which metadata such as website headings and summaries is structured and described, and is mainly used to publish update information of websites. In the document described in RSS, the title, address, heading, summary, update time, etc. of each page of the website can be described.

  In this portable information terminal, update information of a registered website distributed from a feed by RSS, that is, RSS information is automatically received by the wireless communication module 8 and stored in the flash memory 5. By tapping and selecting the title of the desired content on the screen, the content can be browsed as appropriate. In addition to the above, applications such as chat and Skype can be executed.

  And the characteristic process by this portable information terminal is the following points in particular.

  That is, when the CPU 1 functions as a control unit, the communication unit automatically connects to the network via the communication I / F 7 and the wireless communication module 8 that function as a communication unit at a predetermined time, and acquires updated content. And the communication unit is controlled to automatically disconnect from the network after the updated content is acquired. Here, the updated content refers to, for example, RSS information. Further, the CPU 1 controls to turn off the power of the communication unit when automatically disconnecting from the network. When the power is turned off at a predetermined time, the CPU 1 controls to turn on the power to acquire content. You may make it control so that a power supply may be turned off after content acquisition. Further, the CPU 1 accepts an input of a comment for the acquired content, temporarily stores the comment information in the RAM 4 or the flash memory 5 as a recording unit, and the comment unit receives the comment from the recording unit when automatically connected to the network. The information may be controlled to be read and uploaded, and the comment temporarily stored in the recording unit may be controlled to be deleted after being uploaded.

  When functioning as a control unit, the CPU 1 may display a warning on the LCD 18 serving as a display unit when the comment information temporarily stored in the flash memory 5 serving as a recording unit exceeds a predetermined amount. In this case, for example, when the number of comments reaches a predetermined number (100, etc.), a warning is displayed so as to connect to the network. Alternatively, when the CPU 1 functions as a control unit, when the comment information temporarily stored in the flash memory 5 as a recording unit exceeds a predetermined amount, the CPU 1 automatically controls connection to the network and uploads the comment. Good. In this case, for example, when the comment information reaches a predetermined number (100, etc.), the comment may be uploaded by automatically connecting to the network.

  In addition, when the CPU 1 functions as a control unit, when the storage capacity of the flash memory 5 or the like as a recording unit exceeds a predetermined amount, the CPU 1 controls to automatically connect to the network and upload comment information, and to delete content. The content may be controlled to be deleted according to the rank. The deletion priority order includes the oldest content acquisition date, the largest data size, and the content type order. For example, in the case of classification order, the limited storage area is effectively used according to the text such as moving images, music, still images, and news.

  When a plurality of types of recording units such as the flash memory 5 and the recording medium 3 are provided, the CPU 1 may function as a control unit and select a storage to be stored according to the storage priority order of the contents. For example, the priority may be set in the order of a Memory Stick (registered trademark) as a recording medium and a flash memory 5 as a storage in the terminal. Or you may select the storage preserve | saved according to the classification of content. In this case, for example, moving images, music pieces, and still images may be stored in a memory stick as a recording medium 3 and texts such as news may be stored in a flash memory 5 as an in-terminal storage.

  FIG. 2 shows and describes the external configuration of a portable information terminal according to an embodiment of the present invention.

  As shown in the figure, the portable information terminal is configured such that the housing 23 is slidable in the direction indicated by the arrow X in the figure, that is, can be opened and closed with respect to the housing 22. A flat screen 25 of the housing 22 is provided with a touch screen 26 in which an LCD and a touch panel are integrated, and a power button 27. A so-called QWERTY keyboard included in the operation input unit 16 is disposed on the flat surface 24 exposed when the housing 23 of the portable information terminal is open.

  Next, FIG. 3 shows and describes a software stack related to the software configuration that is read from the ROM 6 by the CPU 1 and executed.

  As shown in FIG. 3, the software includes a hardware layer 30, a device driver layer 31, an operating system (OS) layer 32, a middleware layer 33, and an application layer 34. Hereinafter, each layer will be described in more detail.

  The hardware layer 30 includes a sub CPU 30a, a main CPU 30b, a storage device 30c, and the like. The device driver layer 31 is software for operating hardware. For example, a driver for operating the wireless communication module 8, a driver for driving and controlling the LCD driver 17 for causing the LCD 18 to perform various displays, a driver for operating the operation input unit 16, and the like are included. An OS is mounted on the OS layer 32.

  The middleware layer 33 is configured by middleware that operates on the OS and provides application software with more advanced and specific functions than the OS. In this example, at least a power manager 33a, a connection manager 33b, and a storage manager 33c are installed as the middleware. In the uppermost application layer 34, various application programs are executed.

  For example, individual applications such as a connection manager UI, a network application, a web browser, an audio player, a photo viewer, and a text editor are assumed as this application. However, it is not limited to this.

  The portable information terminal according to this embodiment is particularly characterized by power management by the power manager 33a of the middleware layer 33, network connection management by the connection manager 33b, and storage management by the storage manager 33c.

  The outline of each management will be described in detail below with reference to the conceptual diagram of FIG.

  When the application 34 is executed by the main CPU 30b, the application 34 instructs the power manager 33a to register activation time (# 1). Upon receiving this instruction, the power manager 33a sets the activation time for the sub CPU 30a (# 2). In parallel with the activation time setting, the power manager 33a instructs the main CPU 30b to shift to the sleep mode (# 3). Based on this instruction, the main CPU 30b shifts to the sleep mode. Here, the sleep mode refers to a power saving mode.

  Subsequently, the sub CPU 30a monitors the elapse of the activation time in synchronization with the clock signal of the clock generator 35 (# 4), and when the predetermined time (predetermined time) is reached, instructs the main CPU 30b to activate ( # 5). That is, the main CPU 30b shifts from the sleep mode to the normal mode based on the activation instruction from the sub CPU 30a.

  After shifting to the normal mode, the main CPU 30b reports activation to the connection manager 33, and the connection manager 33b notifies the application 34 that the main CPU 30b has been activated (# 6). Upon receiving this notification, the application 34 instructs the connection manager 33b to connect to the network (# 7). Further, the application 34 instructs the storage manager 33c to perform a storage check (# 8). Here, “storage check” is to confirm in advance whether or not the remaining amount of storage is compatible with reception of RSS information. The application 34 receives the result of the storage check, selects the storage, etc., and then instructs the storage manager 33c to cache, and the storage manager 33c caches the RSS information for the storage device 30c (# 9).

  Through the above processing, the power manager 33a appropriately controls the transition of the main CPU 30b to the sleep mode by setting the activation time of the main CPU 30b in cooperation with the power supply circuit 9 as the power management part of the portable information terminal. Then, the main CPU 30b is turned on at the RSS tour start time and the main CPU 30b is turned off at the RSS tour end time (RSS tour function, power management cooperation function).

  The connection manager 33b automatically connects the portable information terminal to the network at the start of the RSS tour, and automatically disconnects at the end of the RSS tour (automatic connection / disconnection function).

  In addition, the storage manager 33c implements a function of circulating ford (Feed) subscribed at the time designated by the application and caching it locally (storage device 30c). The cache target is an updated contents table of contents (RSS / ATOM) file distributed by the Web Feed distribution service and article body pages (resources necessary for correctly displaying HTML and HTML) referenced in the table of contents. . When the web feed distribution service distributes Podcast, the Podcast content (for example, an audio file or a moving image file) is also cached.

  The storage manager 33c can also limit the maximum storage usage that can be used in the RSS patrol (storage usage limitation function). Furthermore, if the portable information terminal has a plurality of storages (flash memory 5, recording medium 3, HD (not shown), etc.), the storage manager 33c can specify a storage to be used for RSS patrol, and a combination of a plurality of storages can be used. Can be specified (cache storage specification function).

  In addition to the above, the connection manager 33b also implements a function of resuming the RSS tour that was interrupted when the wireless connection was established (recirculation function). That is, when the network connection is disconnected during the RSS tour, an error is displayed on the screen of the LCD 18 and the fact is reported to the user, and the connection manager 33b interrupts the RSS tour and monitors the network status. In this case, when the portable information terminal is connected to the network again, the connection manager 33b connects to the network and automatically restarts the RSS patrol.

  Hereinafter, with reference to the flowchart of FIG. 5, the RSS information reception process by the portable information terminal according to the embodiment of the present invention will be described in more detail. The following processing is performed when the CPU 1 (sub CPU 30a or main CPU 30b) executes the power manager 33a, connection manager 33b, storage manager 33c, or application 34, which is the middleware 30, on the OS 32.

  Here, the description will be made with reference to the screen display examples of FIGS.

  The sub CPU 30a monitors the designated time for starting the RSS tour in synchronization with the clock signal of the clock generator 35 (step S1), and instructs the main CPU 30b to start when the designated time is reached. Thereby, each part including the main CPU 30b is turned on, and the RSS patrol function is activated (step S2).

  Here, regarding the RSS patrol, various settings can be performed on the screen 100 as shown in FIG. In other words, the area 100a of the screen 100 is an input area for a check box for setting “Perform periodic patrol”, and the area 100b is an input area for a set time. In this example, two types of set times can be input. The area 100c is an input area for setting the frequency of RSS patrol, and it is also possible to set the desired frequency of RSS patrol by checking the check box of the month-day of the area 100d below. Yes. The area 100e is an input area for storage management, and the storage name and capacity of the cache destination can be set. When the OK button 100f is pressed (tapped) after the above setting, the automatic patrol setting is completed. Furthermore, the setting can be deleted by pressing the cancel button 100g after the input. In addition, the input information can be cleared by pressing the clear button 100f.

  Furthermore, various settings can be made on the RSS circulation destination on the screen 101 as shown in FIG. That is, the area 101a is an input area for setting a feed name, and the area 101b is an input area for setting a URL (Uniform Resource Locator) of the feed. When the clear button 101c is pressed, these setting information can be cleared. The area 101d is a check box for setting whether or not the local cache (storage device 30c) is used. Use of the local cache is permitted by checking this check box.

  In other words, the use of a local cache can be set for each feed (ON / OFF for offline use). When ON, the body text HTML page of the article and Podcast content are cached locally by the RSS patrol function. The main body HTML page and Podcast content are not cached locally by the RSS patrol function, and only the content delivered by RSS such as the title and summary is updated.

  The area 101e is an input area for designating the number of articles obtained by RSS patrol for each feed. That is, the number of articles cached locally can be specified for each feed. In this example, it is specified that a maximum of three articles are obtained. When the OK button 101f is pressed after the above settings, the automatic patrol setting is completed. Furthermore, the setting can be deleted by pressing the cancel button 101g after inputting various information into the input area.

  Returning to the description of FIG. 5 again, the connection manager 33b controls to automatically connect to the network based on the above settings (step S3). After the completion of this network connection, RSS information reception processing is performed by RSS circulation (step S4).

  During reception of this RSS information, that is, during feed update (update information acquisition), a screen 102 as shown in FIG. 8 is displayed on the LCD 18. If the cancel button 102a on the screen 102 is pressed during this update, the reception process is interrupted.

  The storage manager 33c specifies the storage for cache based on the above setting (step S5), and caches the RSS information in the specified local cache (storage device 30c) (step S6). At the time of caching, the storage manager 33c determines whether or not the storage usage limit has been exceeded based on the above setting (step S7). If the storage usage limit has not been exceeded, the power manager 33a ends. It is determined whether it is time (step S8). If it is not the end time, the process returns to step S4 and the above process is repeated.

  If it is determined in step S7 that the storage usage limit has been exceeded (step S7 branches to Yes), or if it is determined in step S8 that the end time is reached (step S8 branches to Yes), the connection manager 33b The connection is automatically disconnected (step S9), the power manager 33a finishes the RSS patrol function, turns off the power (step S10), and thus ends the process of the example.

  The RSS information obtained by the above processing can be appropriately viewed on the LCD 18 on the screen 103 as shown in FIG. That is, in the left area 103a of the screen 103, the set RSS name and the number of updated articles (corresponding to the area 103c) circulated in RSS are displayed. When one feed name is selected, an article (updated) obtained from the feed is selected. Information) title is displayed in the right area 103b, and the article can be appropriately browsed by selecting the desired article.

  In addition, when music information etc. are updated by Podcast, it can view suitably. In this case, when the CPU 1 (main CPU 30b) executes the application 34, an integrated management / display function of articles and Podcast contents is used to display a mini player that plays multimedia contents in the article summary column as shown on the screen 103. By displaying (corresponding to the area 103d), the HTML content of the article and the audio content of Podcast are integrated.

  In the portable information terminal according to this embodiment, the CPU 1 (main CPU 30b) executes the application 34, thereby realizing a function of seamless switching between local cache and online content. With this function, it is possible to automatically determine on the terminal side whether to cache locally or use online content according to the network connection status of the portable information terminal, and display without switching the screen.

  In addition to the above, when the CPU 1 (main CPU 30b) executes the application 34, an article read / unread state switching function is realized. This is to store unread / read for each article obtained from the feed by RSS patrol. The read / unread status of an article is “unread” as the default value of a new article. When opened (for example, displayed on the screen), it automatically changes to “read”. As an example, the read / unread state may be stored by turning on / off a predetermined flag.

  Note that the read / unread state of an article can be explicitly specified by the user.

  In this case, examples of operations that the user can perform with the function include the following.

  ・ Unread one article.

  -Mark as read in feed units.

  ・ Mark as read in units of 1 holder.

  -Mark all subscribed feeds as read at once.

  On the other hand, in the portable information terminal according to this embodiment, the CPU 1 (main CPU 30b) executes the application 34, thereby realizing a comment function for commenting on an article obtained from a feed by RSS patrol. In this case, when online, the functions provided by each service are used as they are (Web Browser Base). When offline, a text editor is started and comments are written, the comments are stored for each article, the comments are read out online, and pasted on the site with a copy plague. .

  As described above, according to the portable information terminal, the control method, and the program according to the embodiment of the present invention, at least one of the following effects is achieved.

  That is, according to the RSS patrol function that patrols the feed at a specified time and caches it locally, it is ensured that the subscription information is always up-to-date. According to the recirculation function for resuming the suspended RSS tour after the network connection, it is possible to appropriately cope with a case where the tour is interrupted due to the traveling tour. According to the automatic connection / disconnection function to / from the network at the start / end of the RSS patrol function, it is possible to reduce the power consumption of the battery. According to the storage usage limit function, it is possible to efficiently use limited resources. According to the cache storage designation function, it is possible to efficiently use limited resources. According to the power management cooperation function, it is possible to efficiently use limited resources.

  Also, RSS reader / offline use function, specifically, offline use (local cache) ON / OFF function for each feed, number of articles to be cached locally, deletion of contents cached locally by RSS patrol It consists of functions, but according to the functions, efficient use of resources is achieved and user convenience is improved.

  According to the seamless switching display function between the local cache and the online content, user convenience is improved. According to the article read / unread state switching function, the user can manage his / her own situation, and the information collection efficiency is improved. According to the comment function for an article, it is possible to write a comment even when offline, which improves the convenience for the user. Further, according to the integrated management / display function for articles and Podcast contents, usability can be improved by reducing the number of screens by unifying articles and Podcast contents.

  The embodiment of the present invention has been described above, but the present invention is not limited to this, and it is needless to say that various improvements and changes can be made without departing from the spirit of the present invention.

  For example, when the accumulation of RSS information in the storage exceeds the capacity limit, a predetermined priority order is assigned to each feed, and content is deleted according to the priority order to solve the capacity limitation problem. It may be. In addition, in the recirculation, for example, a situation that does not hinder the use by the user, such as during charging of the portable information terminal, may be set in advance and performed under the situation.
