The television 1 determines the priority based on the electronic signature and the purpose of the content.

[Configuration of mobile phone 1]
First, the configuration of the mobile phone 2 for transmitting a plurality of control images 5 to the television 1 will be described. FIG. 4 is a block diagram showing a main configuration of the mobile phone 2 according to the embodiment of the present invention.

  As shown in FIG. 4, the mobile phone 2 of the present embodiment includes a control unit 60, a storage unit 61, a short-range communication unit 62, a public line communication unit 63, a screen display unit 64, and an operation input unit 65. It has become.

  The short-range communication unit 62 transmits the control image 5 received from the server 3 via the public communication line 4 by the mobile phone 2 to the television 1 using the short-range wireless communication means. As the short-range wireless communication means, it is possible to use appropriate means such as infrared communication such as IrDA and IrSS, short-range wireless communication such as Bluetooth communication and WiFi communication, or non-contact type IC card such as Felica. . In the present embodiment, it is assumed that the short-range communication unit 62 includes an infrared light emitting unit that transmits an image (control image 5) using an infrared communication protocol (IrSS protocol). The short-range communication unit 62 transmits an infrared carrier wave carrying the control image 5 from the infrared light emitting unit to the light receiving unit of the television 1 compatible with IrSS.

  The public line communication unit 63 communicates with an external device via the public communication line 4. Specifically, the mobile phone network such as 3G or 3.5G is used to make a call with another mobile phone or a general fixed phone, or connected to the Internet to transmit / receive data to / from an external device such as the server 3 Or do. In particular, the public line communication unit 63 can receive the control image 5 supplied by the server 3. As a method for the public line communication unit 63 to obtain the control image 5, for example, there is a method in which the user downloads from the server 3 via a site browsed during Web browsing. Alternatively, various methods are conceivable, such as the server 3 sending an electronic mail with the control image 5 attached, such as an advertisement mail or a mail magazine, and the public line communication unit 63 receiving it.

  The storage unit 61 stores a control program and an OS program executed by the control unit 60 and various data read when the control unit 60 executes various functions of the mobile phone 2. The storage unit 61 is configured by a nonvolatile storage device such as a hard disk. The storage unit 61 includes, for example, a control image storage unit 80 for storing the control image 5 acquired from the server 3 via the public line communication unit 63.

  The screen display unit 64 displays an image stored in the mobile phone 2 or displays an operation screen for a user to operate the mobile phone 2 as a GUI (Graphical User Interface) screen. For example, a selection screen and a selection button are displayed so that the user can select which control image 5 is transmitted to the television 1, or a list of control images 5 stored in the control image storage unit 80 is displayed. To do. The screen display unit 64 is configured by a display device such as an LCD (liquid crystal display).

  The operation input unit 65 is for a user to input an instruction signal to the mobile phone 2. The operation input unit 65 includes a button (a cross key or a determination key), a touch panel, a touch sensor, or an appropriate input device such as a voice input unit and a voice recognition unit.

  The control unit 60 performs overall control of each unit included in the mobile phone 2 and includes at least a selection image acquisition unit 70 as a functional block. In the selected image acquisition unit 70, a central processing unit (CPU) reads a program stored in a storage unit 61 realized by a ROM (read only memory) or the like into a RAM (random access memory) or the like (not shown). It is a functional block that can be realized by execution.

  The selected image acquisition unit 70 acquires the control image 5 for short-range wireless transmission to the television 1 from the control image storage unit 80 and transmits the control image 5 to the short-range communication unit 62. The selected image acquisition unit 70 extracts one or more control images 5 to be transmitted from the control images 5 stored in the control image storage unit 80 based on predetermined conditions.

  The selection image acquisition unit 70 may acquire the control image 5 selected by the user by operating the operation input unit 65, for example. When a folder for managing a plurality of control images 5 is selected, all the control images 5 in the folder are acquired. Alternatively, the control image 5 that matches the condition may be acquired based on the specified condition. For example, when the user designates the condition “received in the last week”, the selected image acquisition unit 70 extracts only the control image 5 that matches the above condition from the control image storage unit 80 and closes it. This is transmitted to the distance communication unit 62.

  Thereby, the short-range communication unit 62 can transmit the plurality of control images 5 to the television 1 at a time.

  In the present embodiment, the control image 5 acquired from the server 3 is stored and managed in the control image storage unit 80 of the mobile phone 2 for each reception time. Specifically, as shown in FIG. 5, the control image storage unit 80 creates a folder for each week, such as what was received this week, what was received last week, what was received two weeks ago, and so on. Each control image 5 is managed under a predetermined folder according to the received time. In the example shown in FIG. 5, there are a total of nine control images 5 received this week. The control image storage unit 80 also manages the electronic signature, Purpose (content purpose), etc. embedded in each control image 5 so that the corresponding relationship is maintained.

  For example, if the user uses the operation input unit 65 to select the “this week” folder shown in FIG. 5 as a transmission target, the selected image acquisition unit 70 manages the above nine images managed in the “this week” folder. The control image 5 is acquired and transmitted to the short-range communication unit 62.

[Processing flow 1 of mobile phone 2]
Next, a process flow when the mobile phone 2 transmits a plurality of control images 5 will be described. Here, the operation of the mobile phone 2 will be described with reference to FIGS. 6 and 7 in the case of transmitting the control image 5 shown in FIG.

  FIG. 6 is a flowchart showing a flow of processing for transmitting the control image 5 of the mobile phone 2 in the present embodiment. FIG. 7 is a diagram illustrating a specific example of a GUI screen displayed on the mobile phone 2 and a state of transition of the GUI screen.

  When an application for transmitting the control image 5 is activated on the mobile phone 2, the screen display unit 64 first displays a GUI screen (for example, Scr1 in FIG. 7) for allowing the user to select the control image 5 to be transmitted. Is displayed (S1 in FIG. 6). On the GUI screen, the control images 5 to be selected may be displayed individually, or may be displayed so that they can be selected for each folder. In the example shown in Scr1 of FIG. 7, the folders grouped according to the time of acquisition such as “today”, “this week”, “last week”, and “two weeks ago” are displayed in a list so that the user can select them. Yes. However, the GUI screen for displaying the options is not limited to the above. In addition, folders grouped according to the creation date of the control image may be displayed, or an analysis function for analyzing the control image by the mobile phone 2 is installed, and control is performed for each Purpose included in the EMAP file of the control image 5 The image 5 may be managed and the folder may be displayed as an option.

  Subsequently, when the user selects a transmission target and presses the enter button (YES in S2), the selected image acquisition unit 70 identifies the folder or control image 5 selected by the user, and selects the identified control image 5. Extracted from the control image storage unit 80. If the selected folder is a folder, all control images 5 included in the folder are extracted (S3). For example, as illustrated in FIG. 7, when the determination button is pressed in the Scr1 on the GUI screen in a state where the cursor is placed on the folder “this week”, the selection image acquisition unit 70 displays “ Nine control images 5 included in the “Weekly” folder are extracted. Then, the screen display unit 64 displays a GUI screen (FIG. 7 Scr2) for confirming to the user whether or not the nine extracted control images 5 may be transmitted. Here, in the example shown in Scr2 of FIG. 7, when the “Yes” button is pressed, the selected image acquisition unit 70 transmits the nine extracted control images 5 to the short-range communication unit 62. In this way, erroneous transmission can be prevented by providing a confirmation screen before actual transmission.

  The short-range communication unit 62 sequentially transmits the nine control images 5 transmitted from the selected image acquisition unit 70 to the television 1 (S4). When the short-range wireless communication means to be employed has directivity as in infrared communication such as IrSS as in the present embodiment, the transmitting unit (light emitting unit) is directed to the receiving unit (light receiving unit) of the television 1. As described above, it is desirable to display a message for alerting the user on the screen of the screen display unit 64. If there are a plurality of selected control images 5 and there is an untransmitted control image 5 (YES in S5), the process of S4 is repeated until all the control images 5 are transmitted. At this time, as shown in the GUI screen Scr3 in FIG. 7, when the control image 5 being currently transmitted is displayed in what number of the number to be transmitted, the user can grasp the progress of the transmission at a glance.

  In this way, the mobile phone 2 can transmit a plurality of control images 5 to the television 1 using the short-range wireless communication means.

[TV configuration 1]
Next, the configuration of the television 1 for receiving a plurality of control images 5 from the mobile phone 2 and sequentially reproducing them will be described. FIG. 1 is a block diagram illustrating a main configuration of a television 1 according to an embodiment of the present invention.

  As shown in FIG. 1, the television 1 of this embodiment includes a control unit 10, a storage unit 11, a short-range communication unit 12, a public line communication unit 13, a screen display unit 14, an operation input unit 15, and an audio output unit 16. It is the composition provided with.

  The short-range communication unit 12 performs short-range wireless communication with the mobile phone 2. The short-range communication unit 12 receives the control image 5 transmitted by the short-range communication unit 62 of the mobile phone 2 using a short-range wireless communication unit. As the short-range wireless communication means, it is possible to use appropriate means such as infrared communication such as IrDA and IrSS, short-range wireless communication such as Bluetooth communication and WiFi communication, or non-contact type IC card such as Felica. . In the present embodiment, it is assumed that the short-range communication unit 12 includes an infrared light receiving unit that receives an image (control image 5) using an infrared communication protocol (IrSS protocol). The near field communication unit 12 receives an infrared carrier wave carrying the control image 5 from the light emitting unit of the mobile phone 2.

  The public line communication unit 13 communicates with an external device via the public communication line 4. Specifically, the public line communication unit 13 communicates with a LAN, a router, and the like in the home (premises), and communicates with the server 3 by connecting to the Internet via the router. The public line communication unit 13 accesses the position of the server 3 indicated by the URL via the public communication line 4 and downloads the content distributed by the server 3. This download of content is executed in accordance with an instruction from the playback content acquisition unit 23.

  The storage unit 11 stores a control program and an OS program executed by the control unit 10 and various data read when the control unit 10 executes various functions of the television 1. The storage unit 11 is configured by a nonvolatile storage device such as a hard disk. In the present embodiment, the storage unit 11 includes a priority determination table 30 and a determination support table 31 that the control unit 10 refers to when determining the priority. Further, the storage unit 11 may include, for example, a control image management table 32 for storing and managing the control image 5 acquired by the short-range communication unit 62 from the mobile phone 2. However, the storage unit for storing and managing the control image 5 is not limited to the above configuration. For example, in a use case in which a plurality of control images are received and played back only once at that time, there is no need to keep saving when the television 1 is turned off and turned on again. Therefore, the storage unit may be configured by a volatile storage device.

  The screen display unit 14 displays the image of the control image 5 acquired from the mobile phone 2 or displays the content acquired from the server 3. When the content includes display objects such as image data, video data, or HTML data acquired via a Web browser, the screen display unit 14 displays a result of processing the content by the control unit 10. (Play). An operation screen for the user to operate the television 1 may be displayed as a GUI screen. The screen display unit 14 includes a display device such as a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), or a CRT (Cathode-Ray Tube) display.

  The operation input unit 15 is for a user to input an instruction signal to the television 1. The operation input unit 15 includes a button (such as a cross key or a determination key), a keyboard, a mouse, a touch panel, a touch sensor, or an appropriate input device such as a voice input unit and a voice recognition unit. The input device is not limited to the above. In the present embodiment, it is assumed that the operation input unit 15 is configured by a remote controller that is provided with a plurality of keys and remotely operates the television 1. The instruction signal input by the user using the operation input unit 15 is sent to each unit of the control unit 10 via an input / output control unit (not shown). Thereby, the user can operate the television 1.

  The audio output unit 16 outputs music (sound) obtained by reproducing content composed of music data, audio data, and the like, and includes a speaker or the like.

  The control unit 10 performs overall control of each unit included in the television 1, and includes at least an analysis unit 20, a reproduction order determination unit 22, and a reproduction content acquisition unit 23 as functional blocks. Further, a priority determination unit 21 and a screen control unit 24 may be provided. Although not shown here, the control unit 10 includes a content reproduction processing unit. The content reproduction processing unit performs reproduction processing of contents in various data formats acquired by the reproduction content acquisition unit 23 and outputs the processing results to each unit such as the screen control unit 24 and the audio output unit 16. The content playback processing unit performs playback of moving images, playback of music, display of still images, and display of WEB content.

  Each unit of the control unit 10 is executed by a CPU (central processing unit) reading a program stored in the storage unit 11 realized by a ROM (read only memory) or the like into a RAM (random access memory) or the like (not shown). This is a functional block that can be realized.

  The analysis unit 20 analyzes the control image 5 acquired from the mobile phone 2 and associates the control data of the analysis result with the image and stores them in the control image management table 32.

  Here, the control data included in the control image 5 is the EMAP file 150 shown in FIG. The EMAP file 150 includes “Purpose” indicating the purpose of the control (content type, TV operation), presence / absence of an electronic signature that is used to determine whether the control image 5 is reliable, valid / invalid information, It contains a URL that represents the location of the content necessary for this. The analysis unit 20 analyzes the information and stores the analysis result in the control image management table 32.

  The priority determination unit 21 determines the priority of the control image 5 based on the result analyzed by the analysis unit 20. Here, the priority indicates the importance of the control image 5 and the degree to be preferentially processed, and is given to each control image 5. When a plurality of control images 5 are processed, this is an index for determining the processing order of the control images 5. In the present embodiment, the smaller the priority value, the stronger the degree of priority processing.

  In the present embodiment, the priority determination unit 21 determines the priority with reference to the determination support table 31 and the priority determination table 30 stored in the storage unit 11. The priority determination table 30 stores a table that defines how to determine the priority of the control image 5 having what parameters. The priority determination unit 21 stores the priority determined for each control image 5 in association with each control image 5 in the control image management table 32.

  The reproduction order determination unit 22 determines the order of processing the plurality of control images 5 (mainly content reproduction processing in the present embodiment). The playback order determination unit 22 determines the playback order of each control image 5 based on the control data and priority of each control image 5 stored in the priority determination table 30. The playback order determination unit 22 stores the determined playback order in association with each control image 5 in the control image management table 32.

  Furthermore, in the present embodiment, the playback order determination unit 22 performs content acquisition and playback processing according to the control data of the control image 5 when it is determined that the electronic signature embedded in the control image 5 is invalid. Do not run. Therefore, in addition to determining the playback order, the playback order determination unit 22 also determines that “no playback is performed” for the control image 5. For the control image 5 determined in this way, the playback order determination unit 22 associates a flag indicating “playback prohibition” (hereinafter referred to as playback prohibition flag (processing prohibition information)) instead of the playback order, and performs control image management. Store in table 32.

  The playback content acquisition unit 23 executes processing for acquiring content according to the control data of the control image 5 in the order determined by the playback order determination unit 22. More specifically, first, the reproduction content acquisition unit 23 acquires a URL obtained by the analysis unit 20 analyzing the control image 5. Based on the URL, the public line communication unit 13 is controlled to access the server 3 that stores the content indicated by the URL. Then, the content to be reproduced is acquired from the server 3 via the public communication line 4.

  When the playback content acquisition unit 23 acquires content according to the playback order, a content playback processing unit (not shown) sequentially plays back the content and transmits the processing result to the audio output unit 16 or the screen control unit 24. Thereby, the content can be reproduced based on the order determined by the reproduction order determination unit 22.

  In the case where reservation of recording is instructed in the command statement of the control image 5, the playback content acquisition unit 23 makes a recording reservation to the recording device instead of directly acquiring content from the outside. An operation of instructing (instructing content acquisition) may be performed.

  Further, in the present embodiment, the playback content acquisition unit 23 does not process the control data in the Exif area 50 for the control image 5 to which the playback prohibition flag is assigned. As a result, it is possible to prevent processing of the control image 5 whose signature is invalid and unreliable. The reproduction prohibition flag may be canceled by a user operation. When the reproduction prohibition flag of the control image 5 is canceled, the reproduction content acquisition unit 23 may acquire the content according to the control data of the control image 5.

  The screen control unit 24 determines the screen configuration and layout of each display object such as a moving image, a photograph, an image, and an OSD (On-Screen Display) image, and outputs a video signal based on the screen configuration to the screen display unit 14. To do. Examples of the display object include content acquired by the reproduction content acquisition unit 23, an image included in the image area 51 of the control image 5, or a GUI screen generated by the control unit 10. The screen configuration is determined by, for example, determining the number of screen divisions, division size, etc. when displaying a plurality of images on one screen, or superimposing an OSD image on a photo at a specific position. is there.

  Further, in the present embodiment, the screen control unit 24 performs processing on the control image 5 to which the reproduction prohibition flag is assigned by the reproduction order determination unit 22 instead of the reproduction content acquisition unit 23. Specifically, after the playback content acquisition unit 23 performs the playback process of the control image 5 according to the determined playback order, first, the screen control unit 24 has not been played back based on the playback prohibition flag. The control image 5 is specified. Then, together with the images stored in the image area 51 of those control images 5, a notice that these are unreliable control images 5 is output to the screen display unit 14. Further, a GUI screen asking whether or not playback is necessary may be output. Thus, the user can check the presence or absence of the unreliable control image 5 by looking at the screen display unit 14 and can instruct the television 1 whether or not to reproduce them.

  Here, when a playback instruction is input from the operation input unit 15 to the unreliable control image 5, the playback order determination unit 22 cancels the playback prohibition flag of those control images 5, and playback is performed in a plurality of cases. Determine the order. The playback content acquisition unit 23 acquires content according to the control data of the unprocessed control image 5 in accordance with the playback order newly given.

[About the table]
Next, various tables stored in the storage unit 11 will be described.

  FIG. 8 is a diagram illustrating a specific example of the data structure of the control image management table 32 that manages the control image 5. As shown in FIG. 8, in the control image management table 32, various types of information about the control image 5 are stored in association with each received control image 5.

  In the present embodiment, the analysis unit 20 assigns a control image ID to the control image 5 transmitted from the mobile phone 2 in the order of reception, and stores it in the “control image ID” field shown in FIG. Therefore, here, the control image ID indicates the reception order as it is.

  The analysis unit 20 analyzes the image area 51 of each control image 5 and stores the file name of the image stored in the image area 51 in the “file name” field.

  The analysis unit 20 analyzes the EMAP file 150 stored in the Exif area 50 of each control image 5. The analysis unit 20 stores the value included in “Purpose (FIG. 3)” of the EMAP file 150 in the “Purpose” field.

  The analysis unit 20 verifies the electronic signature included in the EMAP file 150 of each control image 5. As a result of verifying the electronic signature, the analysis unit 20 determines that the value is “valid” if it is valid, and the value “invalid” if it is invalid. If the electronic signature is not included in the position (“ProviderData (FIG. 3)”), the value of “none” is stored in the “electronic signature” field.

  The analysis unit 20 stores a value (content URL in this embodiment) included in the “URI (FIG. 3)” of the EMAP file 150 of each control image 5 in the “URL” field.

  Next, the priority determination unit 21 determines the priority for each control image 5 by referring to the value of each field for each control image 5 created by the analysis unit 20 and the determination support table 31 in the subsequent stage. To do. The priority determination unit 21 stores the priority of the determination result in the “priority” field of FIG.

  Next, the reproduction order determination unit 22 determines the reproduction order of the control image 5 (and the reproduction prohibition control image 5) with reference to the values of the above-described fields created by the analysis unit 20 and the priority determination unit 21. To do. The playback order determination unit 22 stores the determined playback order (and playback prohibition flag) in the “playback order” field of FIG.

  FIG. 9 shows a specific example of the data structure of the determination support table 31 that is referred to when the priority determination unit 21 determines whether the control image 5 can be processed based on Purpose (in the EMAP file 150 of FIG. 3). FIG. Note that the structure and contents of the determination support table 31 are merely examples, and do not limit the present invention.

  As shown in FIG. 9, in the determination support table 31, the value of Purpose and the content of the operation that can be executed by the television 1 according to the Purpose are stored in association with each other. In this embodiment, the values of Purpose that can be identified and processed by the television 1 are assumed to be the following three types as an example. “PhotoAlbum” is a command for instructing to download image content and display it as a slide show. “Video” is a command that instructs to download the moving image content and play the video. “Music” is a command for instructing to download music content and play music. When other values are included in the Purpose, the television 1 determines that “Unknown” means that the processing method is unknown. Since the processing method of the control image 5 whose “Purpose” is “Unknown” is unknown, the television 1 interprets the content to be displayed on the Web browser for the time being. Note that it is not always necessary to specify a different reproduction operation for each Purpose. If a function such as “Video” and “Music” can be played back by a browser, a playback operation of displaying it by a Web browser may be associated with the purchase as long as there is a function that can be played back by the browser.

  The priority determination unit 21 refers to the determination support table 31 illustrated in FIG. 9, and performs control that can be processed on the television 1 for each control image 5 based on the value of “Purpose” of each control image 5 illustrated in FIG. 8. It can be determined whether the image 5 or the control image 5 whose processing method is unknown (Unknown).

  FIG. 10 is a diagram illustrating a specific example of the data structure of the priority determination table 30 that is referred to when the priority determination unit 21 determines the priority of each control image 5.

  In the present embodiment, the priority determination unit 21 determines the priority of the control image 5 from two viewpoints. The priority determination unit 21 first determines whether or not the electronic signature included in the EMAP file 150 is present and valid when it is present. Second, the priority determination unit 21 determines whether the Purpose included in the EMAP file 150 is a Purpose that can be processed by the television 1. Then, the priority determination unit 21 determines the priority so that the control image 5 having a valid electronic signature and the control image 5 for which a processable process is set in the television 1 are preferentially processed. To do.

  Specifically, the priority determination unit 21 determines that the priority of the control image 5 including a valid electronic signature and a processable Purpose is “1” according to the priority determination table 30 illustrated in FIG. The priority of the control image 5 having a unique electronic signature but the “Unknown” purchase is determined to be “2”, and the priority of the control image 5 including a process that has no electronic signature but can be processed is determined to be “3”. Then, the priority of the control image 5 having no electronic signature and “Purpose” is determined to be “4”.

  In the present embodiment, the smaller the priority value, the higher the priority, and the reproduction order determination unit 22 determines the reproduction order of the control images 5 in consideration of this priority.

  Thereby, it is possible to control the television 1 so as to preferentially process in order from a more reliable and safer control image and a control image that can be reliably processed in the television 1.

  Note that the information used for the priority determination is not limited to the table shown in FIG. 10 and may be realized by an If-Then statement.

[Processing flow of TV 1]
A processing flow of the television 1 will be described with reference to FIG. Here, an outline of the operation of the television 1 from receiving a plurality of control images 5 to reproducing them in order will be described.

  First, the short-range communication unit 12 (FIG. 1) receives the control image 5 transmitted from the mobile phone 2 (S11) and stores it in the storage unit 11. When the control image 5 is stored in the storage unit 11, the analysis unit 20 assigns a control image ID to the control image 5, and each piece of information in the control image management table 32 and the control image main body are associated with each other by the control image ID. It is saved in the state. When a plurality of control images 5 are transmitted, the reception process of S11 is repeated until all the control images 5 are received (NO in S12 → S11).

  When all control images 5 have been received (YES in S12), analysis unit 20 analyzes each control image stored in storage unit 11 (S13). Specifically, the control data (EMAP file 150) of the control image 5 is extracted. In this embodiment, as described above, the analysis unit 20 extracts values from the “Purpose” area and the “URI” area of the EMAP file 150 and stores them in predetermined fields of the control image management table 32. To do. In addition, the presence / absence of an electronic signature stored in the “ProviderData” area is stored in a predetermined field. If there is an electronic signature, the analysis unit 20 verifies the control image 5 and determines whether the electronic signature is valid or invalid. Then, the determination result (valid or invalid) is stored in the predetermined field.

  The result (Purpose, electronic signature, etc.) analyzed by the analysis unit 20 is stored in the control image management table 32 in association with the control image ID. As a result, the analysis result of the control image 5 and the control image main body can be associated and managed by the control image ID. The data stored in association with the control image ID may be the analyzed actual data itself, or may be information indicating the position where the data is stored in the EMAP file 150 of the control image 5. Further, the information indicating the position may be an address on the memory or an offset from the head of the control image. As described above, if only the information indicating the data position is managed in association with the ID, the storage area can be reduced as compared with the configuration in which the actual data of the analysis result is separately stored. The analysis unit 20 analyzes all received control images in S13.

  Subsequently, the priority determination unit 21 determines the priority of the control image 5 based on the analysis result of the analysis unit 20 (S14). The priority determination process will be described in detail later with reference to FIG. If there is a control image 5 that has not been determined yet (YES in S15), the priority determination process in S14 is repeated.

  When the priority determination for all received control images 5 is completed (NO in S15), the reproduction order determination unit 22 reproduces each control image 5 based on the determined priority and the analysis result by the analysis unit 20. Determine the order. The playback content acquisition unit 23 processes the control image 5 based on the determined playback order and acquires content to be played back. The content acquired by the playback content acquisition unit 23 is sequentially processed as soon as it is acquired by the content playback processing unit (S16). The playback order determination and playback processing will be described in detail later with reference to FIG.

[Priority determination process 1]
FIG. 12 is a flowchart showing the flow of the priority determination process of the priority determination unit 21. The priority determination unit 21 refers to the control image management table 32 of FIG. 8 and determines the priority of the control image 5 managed there.

  First, the priority determination unit 21 refers to the field “electronic signature” and checks whether there is an electronic signature for the control image 5 to be determined. If there is an electronic signature (YES in S101), the priority determination unit 21 checks whether the electronic signature is valid or invalid. Here, when the electronic signature is invalid (for example, a flag indicating invalidity is set in the field “electronic signature”, etc., NO in S102), the priority determination unit 21 adds the control image 5 to the control image 5. On the other hand, no processing is performed (S103). Alternatively, the priority determination unit 21 may discard the control image 5 record from the control image management table 32.

  Since the analysis unit 20 verifies the electronic signature in S13 of FIG. 11, at this time, the control image 5 with an invalid electronic signature is discarded, or all such control images 5 are read out. It may be prohibited. In this case, the process for determining the validity / invalidity of the electronic signature in the priority determination process can be omitted.

  On the other hand, for the control image 5 to which a valid digital signature is assigned (YES in S102), the priority determination unit 21 checks the Purpose of the control image 5 (S104). Here, the priority determination unit 21 refers to the determination support table 31 shown in FIG. Then, it is determined whether the Purpose of the control image 5 matches any of “PhotoAlbum”, “Video”, and “Music”. If they match, the Purpose is determined to be a Purpose that can be processed by the television 1 (YES in S105), and the priority of the control image 5 is set to "1" (S106). On the other hand, when the Purpose does not match any of the Purposes managed in the determination support table 31, the priority determination unit 21 determines that the Purpose is an Unknown Purpose in the television 1 (NO in S105). ), The priority of the control image 5 is set to “2” (S107).

  The priority determination unit 21 also determines the priority based on the Purpose for the control image 5 without an electronic signature (NO in S101).

  If the Purpose of the control image 5 matches one of the Purposes managed in the determination support table 31, it is determined that the control image 5 has a processable Purpose (YES in S108). The priority is set to “3” (S109). On the other hand, when none of the Purposes managed in the determination support table 31 matches, it is determined that the control image 5 is the control image 5 having the Unknown Purpose (NO in S108), and the control image 5 Is set to "4" (S110).

  This priority determination process is executed for each control image 5 stored in the storage unit 11. Therefore, the processing of S101 to S110 is repeated until there is no undetermined control image 5.

[Reproduction order determination, reproduction processing 1]
FIG. 13 is a flowchart showing the flow of playback order determination and playback processing in the playback order determination unit 22 and the playback content acquisition unit 23. The playback order determination unit 22 determines the playback order of each control image 5 in consideration of the priority determined as described above, and the playback content acquisition unit 23 acquires content according to the determined playback order. As a result, the content is reproduced in the determined order.

  The reproduction order determination unit 22 refers to the control image management table 32 and determines whether there is a control image 5 whose priority is set to “1” (S201). When there is a control image 5 with priority 1 (YES in S201), the playback order determination unit 22 extracts the control image 5 with priority 1 from the control image management table 32 (S202). Then, the playback order determination unit 22 determines the playback order as “1” for the extracted control image 5 whose reception order is the first (here, the control image ID is the lowest number). The reproduction content acquisition unit 23 processes the top control image 5 according to this determination (S203). That is, the content is acquired from the URL included in the control image 5, and the content reproduction processing unit is instructed to reproduce the content. Here, the Purpose 1 Purpose is known to the television 1, so the content reproduction processing unit can execute the content reproduction method based on the Purpose.

  In the present embodiment, when there are a plurality of control images with priority 1, the playback order determination unit 22 determines the processing order according to the reception order. However, the present invention is not limited to this, and playback is performed. The order determining unit 22 may determine the order according to the creation date and time of the control image, or may determine the priority to be executed in advance for each Purpose and determine it accordingly.

  Subsequently, the reproduction order determination unit 22 determines whether a control image having the same Purpose as the control image 5 processed in S203 is included in the unprocessed control image extracted in S202 (S204). ). If there is an unprocessed control image that matches the Purpose (YES in S204), the reproduction order determination unit 22 determines the control image as a control image to be reproduced next. For example, the playback order is defined as “2”.

  In the example illustrated in FIG. 8, when the control image “Album1.jpg” having the control image ID: 1 is reproduced in S203, the control image to be subsequently processed is the same as the control image “Album1.jpg”. The control image “Album2.jpg” with the control image ID: 4 having “Purpose” is selected. In this way, the control image is repeatedly processed in the order of reception for each identical Purpose (S203 to S205).

  When all the control images with priority 1 are processed (NO in S206), reproduction order determining unit 22 then gives priority to control images with priority 2 (YES in S207). The playback order is determined so as to be processed.

  The reproduction order determination unit 22 extracts the control image 5 having the priority 2 from the control image management table 32 (S208). Then, when there are a plurality of control images 5 with priority 2, the playback order determination unit 22 determines the playback order according to the order of reception. Since the Purpose of the control image 5 extracted here is Unknown, the Purpose is not considered here.

  The reproduction content acquisition unit 23 processes the control image 5 with the priority 2 in accordance with the reproduction order determined by the reproduction order determination unit 22 (S209). Here, the content is acquired from the URL included in the control image 5, and the content is reproduced by the default processing method (in the example shown in FIG. 9, it is displayed in the browser).

  If there is no control image with priority 2 in S207 (NO in S207), or if the processing in S209 is completed, the playback order determination unit 22 then adds priority 3 or priority 4 to the control image management table 32. It is determined whether there is a control image (S210).

  When there is an unprocessed control image with priority 3 or 4 (YES in S210), the reproduction order determination unit 22 automatically reproduces the unprocessed control image without the user's permission because there is no electronic signature. Judge that it should not. Then, the reproduction order determination unit 22 stores the reproduction prohibition flag in association with the control image ID instead of the reproduction order for such a control image.

  In this embodiment, for the control image without the electronic signature, the playback order determination unit 22 performs the process of prohibiting the playback so that the control image is not automatically played back. However, the processing for the control image without the electronic signature is not completed. The television 1 can be configured such that the control image for which automatic reproduction is prohibited is reproduced after the reproduction permission is obtained from the user. In the present embodiment, the screen control unit 24 shifts to a process for displaying a notice that the control image without the electronic signature is unreliable and a confirmation screen asking whether or not to reproduce the control image (content). S211 and after).

  The screen control unit 24 sets the maximum number of divided screens (m divisions) in which the number of unprocessed control images with priority 3 or 4 (n) can be divided and displayed on the screen display unit 14 of the television 1. It is determined whether it exceeds (S211).

  The control image management table 32 shown in FIG. 8 will be described as an example. Since there are three unprocessed control images with priority 3 or 4 at S210, n = 3. As shown in the example of FIG. 15, if the maximum number of screens that can be divided is four, m = 4. In this case, the screen control unit 24 determines that the number of unprocessed control images (n) does not exceed the maximum number of divisions (m divisions) (YES in S211). Then, the screen control unit 24 divides the screen so that all the unprocessed control images can be displayed as a list, and displays the image of the image area 51 of each unprocessed control image, or displays the processing summary explanatory text. Then, a confirmation screen for inquiring whether or not to reproduce these unprocessed control images is displayed (S212). Here, for example, as shown in FIG. 15, the screen control unit 24 divides the screen so that three unprocessed control images can be displayed as a list, displays the unprocessed control images and the content outline, and displays these contents. Display a warning and confirmation screen. Here, the screen control unit 24 may divide the screen into three according to the number of unprocessed control images, or may divide the screen into four according to the maximum number of divisions.

  When there are more unprocessed control images (n) than the maximum number of divisions (m divisions) (NO in S211), the screen control unit 24 divides the screen by the maximum division number m, In addition to displaying the upper m unprocessed control images of n, a note and confirmation screen is displayed (S213). The screen control unit 24 displays the control screens in order of priority (and reception order) from the upper control image, and displays the confirmation screen in a plurality of pages.

  When an instruction to reproduce is input via the operation input unit 15 (YES in S214), the reproduction order determination unit 22 cancels the reproduction prohibition flag of the priority 3 or 4 control image selected by the user. The reproduction content acquisition unit 23 processes the released control image to acquire content (S215). When the priority of an unprocessed control image instructed to be played is 3, the content playback process is executed by a method corresponding to each Purpose. When the priority is 4, the default method is used for content playback. Playback processing is executed.

  For example, when a “play all” button is pressed on the confirmation screen shown in FIG. 15, an instruction to play three control images with control image IDs 6, 8, and 9 is input to the television 1.

  If an unprocessed control image (priority 3 or 4) still remains, if a playback instruction is input from the user (YES in S216 and YES in S214), the playback order determination unit 22 and playback content acquisition The unit 23 repeats the content acquisition process and the reproduction process.

  FIG. 14 is a diagram for explaining the playback order determined for the nine control images managed in the control image management table 32 of FIG. 8 and the flow of the operation of the television 1 that plays back content in accordance with the playback order. According to the playback order determination and playback processing shown in FIG. 13, the playback order of the nine control images is determined as follows.

  Of the nine control images, the first received image with priority 1 is “Album1.jpg” with a control image ID of 1. Therefore, the control image “Album1.jpg” is in playback order 1. Subsequently, a control image having the same Purpose as the control image “Album1.jpg”, that is, “Album2.jpg” with the control image ID: 4 is determined as the reproduction order 2.

  Next, among the remaining control images, “Uta1.jpg” with the control image ID: 2 is received first with priority 1. Therefore, the control image “Uta1.jpg” is in playback order 3. Subsequently, since there is a control image of the same Purpose, “Uta2.jpg” with the control image ID: 5 is the reproduction order 4.

  Next, the remaining control image of priority 1, that is, “Video1.jpg” with the control image ID: 7 is determined as the reproduction order 5.

  Subsequently, since one control image with priority 2 is included in the remaining control images, “Newstopic1.jpg” with the control image and control image ID: 3 is determined as the reproduction order 3.

  The remaining control images, that is, control images with priority 3 or 4 (ID: 6, 8, 9) are unreliable because they have no signature, so it is not known whether they can be automatically reproduced. Therefore, a reproduction prohibition flag is assigned to these three control images instead of determining the reproduction order. For these control images, after the contents of priority 1 or 2 are sequentially reproduced, finally, a process of displaying an image together with a notice and a confirmation screen and asking whether reproduction is necessary is executed.

  As shown in FIG. 14, the television 1 processes nine control images according to the determined reproduction order.

  First, the television 1 sequentially processes the control images of priority 1 and ID: 1 and ID: 4 in this order to acquire content and perform a slide show display process (first process). Next, the television 1 sequentially processes the control images of ID: 2 and ID: 5 in this order to acquire content, and performs music playback processing (second processing). Subsequently, the television 1 processes the control image with ID: 7 to acquire and reproduce the video content (third process).

  Next, the television 1 acquires the control image with the priority 2 and the news content with ID: 3 and displays it on the browser which is the default processing means (fourth process).

  Finally, the television 1 takes out each image stored in the image area 51 from the control images (ID: 6, 8, 9) of priority 3 or 4, and divides it into the screen of the screen display unit 14. Are displayed (fifth process). Here, the television 1 uses only the image in the image area 51 of the control image, and does not process the control data stored in the Exif area 50 (contents are not acquired or played back). Then, the television 1 displays a note indicating that the content is unreliable and a confirmation screen for inquiring whether or not to reproduce the content, as in the display screen example shown in FIG. After the confirmation screen is displayed, when the user selects a control image to be reproduced from the confirmation screen via the operation input unit 15, the television 1 reproduces the control image selected by the user. In other words, the television 1 is configured to reproduce content without an electronic signature after receiving a user instruction without performing automatic reproduction.

  Specifically, the television 1 reproduces the contents with the priority 1 or 2 in order, and does not automatically reproduce the contents with the priority 3 or 4. First, only images are displayed as a list, and are played back only when an instruction from the user is input. That is, the television 1 can process only a plurality of control images that can be processed safely in a sequential order.

  As a result, the television 1 can process a plurality of control images successively in order, but the content with low reliability is not automatically reproduced, so that the content reproduction system can be operated more safely.

  Regarding the information processing system (communication terminal device and information processing device) of the present invention, the second embodiment will be described below with reference to FIGS. For convenience of explanation, members having the same functions as those described in the drawings used in the description of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the present embodiment, a configuration in which the playback order can be designated in advance when the mobile phone 2 transmits the control image 5 to the television 1 will be described.

[Configuration of mobile phone 2]
FIG. 16 is a block diagram showing a main configuration of the mobile phone 2 in one embodiment of the present invention. The cellular phone 2 shown in FIG. 16 is different from the cellular phone 2 shown in FIG. 4 in that the control unit 60 further includes an IDNUM setting unit 71.

  The IDNUM setting unit 71 sets identification information in the control image. More specifically, the IDNUM setting unit 71 first embeds a group ID for managing a plurality of control images as one group in the control data of each control image. Second, a parameter “NUM” (order parameter) indicating a predetermined reproduction order is embedded in the control data.

  In the present embodiment, the playback order is determined by the user operating the mobile phone 2 to specify the playback order. The screen display unit 64 displays a list of control images (contents) stored in the control image storage unit 80. The user selects those control images in the order in which they want to reproduce them. As a result, the IDNUM setting unit 71 assigns the same group ID to the selected control image group, and assigns the serial number NUM in the order in which each control image is selected. In the present embodiment, the IDNUM setting unit 71 embeds the group ID and NUM in the control data of the control image 5. FIG. 17 shows an example of the data structure of the control image 5 when the control data in this embodiment is realized by EMAP.

  For example, assume that the user sequentially selects six control images and the control image 5 is selected third by the user. In the example illustrated in FIG. 17, the IDNUM setting unit 71 stores the group ID “THISWEEK01” to be assigned to the six control images in the UserData field of the EMAP file 150. The IDNUM setting unit 71 sets NUM “3 of 6” indicating that the reproduction order is third because the third selected control image 5 is a control image to be processed third. , And stored in the AdditionalData field.

  Since the control image 5 shown in FIG. 17 is an example, the mobile phone 2 of the present invention is not limited to this. For example, a group ID and NUM can be embedded in the ProviderData field. The parameter NUM may be anything as long as the playback order can be recognized by the television 1, and the IDNUM setting unit 71 may simply embed the serial number as NUM in the EMAP file 150 without describing the denominator.

  The IDNUM setting unit 71 stores and manages each control image in which the group ID and NUM are embedded in the control image storage unit 80. FIG. 18 is a diagram illustrating a specific example of the file structure of the control image storage unit 80 that stores the control image 5 in the present embodiment.

  The difference from the control image 5 shown in FIG. 5 is that each control image 5 is given a group ID and a NUM. For example, when the folder for “this week” is selected by the user, the IDNUM setting unit 71 assigns the group ID “THISWEEK01” to all control images 5 in the folder for “this week”. Then, the IDNUM setting unit 71 assigns NUM to each control image 5 in the selected order.

[Processing flow 2 of mobile phone 2]
Next, a process flow when the mobile phone 2 transmits a plurality of control images 5 will be described. Here, the operation of the mobile phone 2 will be described with reference to FIGS. 19 and 20 in the case of transmitting the control image 5 shown in FIG.

  FIG. 19 is a flowchart showing a flow of processing for transmitting the control image 5 of the mobile phone 2 in the present embodiment. FIG. 20 is a diagram illustrating a specific example of a GUI screen displayed on the mobile phone 2 and a state of transition of the GUI screen.

  When an application for transmitting the control image 5 is activated on the mobile phone 2, first, the screen display unit 64 displays a GUI screen (for example, Scr11 in FIG. 20) for causing the user to select the control image 5 to be transmitted. Is displayed (S21 in FIG. 19). At this time, the screen display unit 64 may display a message so as to select the control image 5 in the order in which it is to be reproduced on the television 1. On the GUI screen, icons are displayed so that the control images 5 to be selected can be individually selected, and the control images can be selected in the order in which the user wants to reproduce them. When the control image is selected by the user (YES in S22), the selected image acquisition unit 70 stores the order in which the control image is selected in a temporary storage unit such as a RAM (not shown) in association with the control image ID ( S23). For example, in the example shown in Scr11, when the “select” button is pressed while the cursor is on the control image, the ID of the control image corresponding to the content of “continuous drama 1 episode” and the selection order “first” Are temporarily stored in association with each other. The selection of the control image is repeated until the user finishes selecting the control image to be transmitted (NO in S24, YES in S22). For the control image 5 that has already been selected, information on the selected order may be displayed (Scr12).

  Next, when the “OK” button is pressed in Scr12 with the user's selection completed (YES in S24), the IDNUM setting unit 71 stores all selected items stored in the temporary storage unit. A group ID is assigned to each of the control images, and a NUM representing the reproduction order is set for each control image based on the associated selection order (S25). Here, as shown in Scr12 and 13 of FIG. 20, the screen display unit 64 may display the control image selected by the user and the selection order, and then transmit it. A screen for inquiring may be displayed. As a result, the control image selected by the user and the selection order can be confirmed before transmission. When the “Yes” button is selected in Scr13, the selected image acquisition unit 70 acquires from the control image storage unit 80 all the control images selected in the repetition process of S22 and S23. The short-range communication unit 62 transmits the control image 5 acquired by the selected image acquisition unit 70 to the television 1 (S26).

  If untransmitted control images remain (YES in S27), S26 is repeated until all the selected control images are transmitted. At this time, the screen shown in Scr14 of FIG. 20 may be displayed on the screen display unit 64 so that the user can confirm the progress of transmission.

  According to the above method, it is possible to determine the playback order of the plurality of control images 5 using the mobile phone 2 that transmits the control images 5 and then transmit them to the television 1.

[TV configuration 2]
Next, the configuration of the television 1 for receiving a plurality of control images 5 from the mobile phone 2 and reproducing the contents in the order designated by the mobile phone 2 will be described with reference to FIG.

  When analyzing the received control image, the analysis unit 20 of the television 1 in this embodiment analyzes the UserData field and AdditionalData field in the EMAP file 150 in addition to the analysis items described above in the first embodiment. The group ID and NUM are extracted. The analysis unit 20 stores the extracted group ID and NUM in the control image management table 32 of the storage unit 11 in association with the control image ID. Here, the analysis unit 20 may store the group ID and NUM values, or may store pointer information in the control image.

  FIG. 21 is a diagram illustrating a specific example of the data structure of the control image management table 32 that manages the control image 5. Compared with the control image management table 32 shown in FIG. 8, the control image management table 32 in the present embodiment is further provided with fields for storing group ID and NUM values. However, when the group ID and the NUM are not embedded in the control image, the analysis unit 20 may leave this field blank or store a flag indicating no value. The group ID and the presence / absence of the NUM managed in this way are used when the priority determination unit 21 determines the priority. The NUM is used when the playback order determining unit 22 determines the playback order.

  When determining the priority of each control image, the priority determination unit 21 of the television 1 according to the present embodiment applies each control image to the control image before the determination based on the presence / absence (valid / invalid) of the electronic signature and the purchase. The priority is determined by first considering whether or not the above-described group ID and NUM are assigned. In the present embodiment, the priority determination unit 21 determines the priority of each control image 5 with reference to the priority determination table 30 shown in FIG. FIG. 22 is a diagram showing a specific example of the data structure of the priority determination table 30 in the present embodiment.

  In the present embodiment, the priority determination table 30 is classified according to the presence or absence of a group ID and NUM, and the control image to which the group ID and NUM are assigned is determined to have the highest priority. The priority determination method for the control image without the group ID and NUM is the same as the priority determination method in the first embodiment described above.

  Specifically, the priority determination unit 21 first determines the priority of the control image 5 including the group ID and NUM as “1 or 2” according to the priority determination table 30 shown in FIG. The priority of the control image 5 is determined as “any of 3 to 6”.

  Subsequently, among the control images having the group ID and NUM, the priority of the control image having a valid electronic signature is determined as “1”, and the priority of the control image having no electronic signature is determined as “2”. To do.

  For the remaining control images without the group ID and NUM, the priority is set to 4 in consideration of the presence of a valid electronic signature and whether or not the process can be processed, as in the first embodiment. Decide in stages. In the present embodiment, those determined as “priorities 1 to 4” in the first embodiment are determined as “priorities 3 to 6”, respectively. The priority determination unit 21 stores the determined priority in the “priority” field of the control image management table 32 shown in FIG.

  By taking into account the priority determined according to the priority determination table 30, the playback order determination unit 22 can determine the playback order in which the user's wish designated by the mobile phone 2 is most accurately reflected. it can. Note that the priority determination table 30 is not limited to the example of FIG. The determination criteria for setting the priority and which determination criteria are regarded as important may be appropriately determined according to the policy of a device (such as the television 1) that handles control images. Specifically, in the example shown in FIG. 23, regarding the priority criterion, (1) presence / absence of group ID and NUM> (2) presence / absence of signature, valid / invalid> (3) whether or not the process can be processed. Are used as important criteria in that order. However, the present invention is not limited to the above, and other criteria may be adopted, the criteria may not be adopted, or the order in which the criteria are regarded as important may be changed.

  For example, in a device (product) having a high brand image, reliability is most important. Therefore, the presence / absence of an electronic signature and the determination criteria for validity / invalidity may be regarded as the most important. Alternatively, in an apparatus that has the advantage of being able to easily and continuously display a large number of all contents, a determination criterion may be selectively employed, such as ignoring the determination criterion for an electronic signature.

  The playback order determination unit 22 of the television 1 in the present embodiment first determines the playback order so that the control images with priority levels 1 and 2 with the group ID and NUM are played back more preferentially. In the present embodiment, the playback order determination unit 22 determines the playback order so that the control images with the priority levels 1 and 2 are played back in principle in the NUM order (user's desired order). Here, the control image of priority 2 is an unreliable control image without an electronic signature. Therefore, the playback order determination unit 22 plays back the playback order and the playback confirmation required flag (or the playback confirmation flag) so that the control image with the priority 2 is played back in the above order after the permission of the user of the television 1 is given. (Prohibition flag) may be associated together.

  In the present embodiment, the reproduction order determination unit 22 performs the same processing as that performed on the control images having the priorities 1 to 4 in the first embodiment for the control images having the priorities 3 to 6. The playback order is determined according to the procedure.

  According to the above configuration, it is possible for the television 1 to determine the final content playback order in consideration of the playback order specified by the user on the mobile phone 2, and to play a plurality of content in order. .

[Priority determination process 2]
FIG. 23 is a flowchart showing the flow of the priority determination process of the priority determination unit 21 in the present embodiment. The priority determination unit 21 refers to the control image management table 32 of FIG. 21 and determines the priority of the control image 5 managed there.

  First, the priority determination unit 21 refers to the fields “group ID” and “NUM” to check whether there is a value. If there is a group ID and NUM (YES in S301), the presence of an electronic signature for the determination target control image is checked by referring to the field “electronic signature”.

  If there is an electronic signature (YES in S302), the priority determination unit 21 checks whether the electronic signature is valid or invalid. Here, when the electronic signature is invalid (for example, a flag indicating invalidity is set in the field “electronic signature”, etc., NO in S303), the priority determination unit 21 adds the control image 5 to the control image 5. On the other hand, no processing is performed (S304). Alternatively, the priority determination unit 21 may discard the control image 5 record from the control image management table 32. Here, a screen for notifying the user that processing cannot be executed because signature verification has failed may be displayed. On the other hand, when the electronic signature is valid (YES in S303), the priority determination unit 21 determines the priority of the control image as “1” regardless of the contents of the Purpose (S305). ).

  On the other hand, when the control image does not have an electronic signature (NO in S302), the priority determination unit 21 determines that the priority of the control image is “2” regardless of the contents of the Purpose (S306). .

  When the control image to be determined does not have a group ID and NUM (NO in S301), the priority determination unit 21 determines the priority of the control image according to the priority determination processing 1 in the first embodiment. (S307). In other words, the priority is determined based on the electronic signature and Purpose. In the present embodiment, control images determined as priorities 1 to 4 in the first embodiment are determined as priorities 3 to 6, respectively.

  The priority determination unit 21 repeats this priority determination processing 2 for each of the control images received together.

[Determination of playback order, playback process 2]
FIG. 24 is a flowchart showing the flow of the playback order determination and playback processing in the playback order determination unit 22 and the playback content acquisition unit 23 in the present embodiment.

  The reproduction order determination unit 22 refers to the control image management table 32 and checks whether or not there is a priority level 1 or a priority level 2 for all the control images to which the priority level is given (S401). When the priority of all control images is any one of 3 to 6 (NO in S401), the playback order of each control image is determined according to the playback order determination and playback process 1 shown in FIG. (S407).

  On the other hand, when there is a priority 1 or priority 2 control image (YES in S401), the playback order determination unit 22 controls priority 1 or 2 among the control images assigned the same group ID. An image is read from the control image management table 32 (S402). Then, the playback order determination unit 22 determines the playback order so that control images with the same priority group ID of 1 or 2 are played back in order from the smallest NUM.

  In the present embodiment, when control images with a plurality of group IDs are mixed in the control image management table 32, the control images having the same group ID may be processed first. If the total number (denominator) is also included in NUM, processing is performed for each group in the order in which they are more complete (in order of “number of control images with the same group ID / total number of NUMs”) (reproduction order). Determination, content acquisition, and playback).

  Next, the reproduction order determination unit 22 determines whether or not there is a control image with priority 2 among the control images whose reproduction order has been determined according to NUM in S402 (S403). Here, when there is no control image of priority 2 (NO in S403), the reproduction content acquisition unit 23 acquires reliable content in the order of NUM, and the content reproduction processing unit sequentially reproduces it (S404). When processing of all control images with priority level 1 is completed (NO in S405), if there are control images with priority level 3 or later (YES in S406), the playback order determination and playback processing shown in FIG. The playback order is determined according to 1, and the content is played back (S407).

  On the other hand, when a control image with priority 2 is included in S403 (YES in S403), the reproduction order determination unit 22 adds a reproduction confirmation necessity flag to the control image together with the reproduction order. When the control images of priority 1 and priority 2 are mixed and continuously processed, the screen control unit 24 performs the following processing based on the reproduction confirmation necessity flag. In other words, a note stating that unreliable content is included in the middle of continuous playback, and confirmation to inquire whether to check each time before performing the content playback processing or whether to perform playback processing without checking all The screen is displayed on the screen display unit 14 (S408). A specific example of the notice and the confirmation screen is shown in FIG. As shown in FIG. 25, if the control image with priority 2 (= low reliability) is displayed together with the image, the visibility of the user is improved.

  In the confirmation screen, when the option “play all” is selected by the user operation (1 in S409), the process proceeds to S404, and the playback content acquisition unit 23 uses the same group ID and has priority 1 or priority. The control image of degree 2 is processed, and contents are acquired in the order determined by the playback order determination unit 22. The content reproduction processing unit sequentially reproduces the acquired content.

  On the other hand, when the “confirm each time” option is selected before reproduction (2 in S409), the reproduction content acquisition unit 23 and the content reproduction processing unit proceed with the control image processing in the order of NUM as in S404 ( S410). If the control image to be processed is priority 1 in the process of S410 (1 in S411), the playback content acquisition unit 23 acquires content according to the control data (EMAP file 150) of the target control image. The content reproduction processing unit reproduces it (S412).

  If there is an unprocessed control image with priority 1 or 2 (YES in S413), the processing after S410 is repeated, and if there are no unprocessed control images (NO in S413), the playback order is determined for priority 3 and later. The process proceeds to the reproduction process (S406, S407).

  On the other hand, when the control image to be processed has priority 2 (2 in S411), the playback content acquisition unit 23 does not acquire content at this time. Instead, the screen control unit 24 presents the image of the target control image (in the image area 51) or the processing outline of the control image to the user on the screen display unit 14. Then, a confirmation screen for inquiring whether or not to execute the control image processing (content acquisition and reproduction) is displayed (S414). For example, a notice and confirmation screen as shown in FIG. 26 is displayed.

  When the user selects the image and an instruction for content playback is input to the television 1 (1 in S415), the playback content acquisition unit 23 acquires content according to the control data of the control image (S412). . On the other hand, when the user selects the “skip” option (2 in S415), the reproduction content acquisition unit 23 skips the process of the control image and there is a next unprocessed control image (S413). In step S410, the process returns to step S410 to process the unprocessed control image in the next reproduction order.

  After the process is executed for all the control images having the same group ID, the process from S401 is repeated for the control image having the next group ID.

  In the above description, when a control image without a signature is included in a series of control images, in S409, the user automatically reproduces all of them or confirms whether or not to reproduce each time immediately before reproduction. However, the present invention is not limited to this. As shown in FIG. 25, an option of automatically skipping only a control image without a signature and automatically reproducing it may be displayed in S408. When the above option is selected in S409, only the control images with priority 1 are sequentially reproduced.

  If the same group includes a control image that is determined not to be processed in S304 of FIG. 23 because the electronic signature is invalid, screen control is performed before the first content of the group is played back. The unit 24 may display a notification screen that notifies the user of the fact on the screen display unit 14. An example of the notification screen is shown in FIG.

  According to the above method, when the television 1 receives a plurality of control images, the television 1 can determine the playback order by reflecting the user's preference with priority, and unless otherwise specified. It is possible to process a plurality of control images in an appropriate reproduction order according to the priority, the purpose of the content (Purpose), and the like. Further, in the present embodiment, the verification result of the electronic signature is also taken into consideration, so that unreliable content can be skipped. Therefore, the user can enjoy continuous automatic reproduction with peace of mind.

  In the present embodiment, the example in which the user of the mobile phone 2 determines the playback order has been described. However, when the server 3 that supplies the control image to the mobile phone 2 generates the control image, the playback order is embedded in advance. It may be left. If it does in this way, continuous contents, such as a drama and a novel, for example can be reproduced in the right order with the composition of television 1 in a second embodiment.
