When pressed, a data type designation tone signal representing the data type to be inserted is generated. For example, “# 0” is inserted when an image is inserted, “# 1” is inserted when vibrator control data is inserted, and “# 2” is inserted when liquid crystal backlight control data is inserted. "# 3" is pressed and a tone signal corresponding to that is generated.

  When image data or fixed text data is inserted into the content, after the data type designation tone signal is generated, the tone data generating device 122 of the authoring terminal 12-1 stores the image data or fixed form previously stored in the data creation server 47. A button corresponding to desired data in the text data and a button corresponding to the time in seconds for displaying the image data or the fixed text data are pressed, and a data designation tone signal and a time designation tone signal corresponding to the button are displayed. Generated.

  When vibrator control data or liquid crystal backlight control data is inserted into the content, the second unit for operating the vibrator or liquid crystal backlight in the tone signal generator 122 of the authoring terminal 12-1 after the generation of the data type designation tone signal A button corresponding to the time at is pressed, and a time-designated tone signal corresponding to the button is generated.

  When free input text data is inserted into the content, a desired text is input from the tone signal generation device 122 of the authoring terminal 12-1, and a data designation tone signal corresponding to the text is generated. In this case, the data type designation tone signal need not be used in order to shorten the time required for text input. For inputting free text data, various existing methods used to input text using a tone signal generator such as a push button can be used. However, it is possible to input text quickly during content creation. It is desirable to use a text input system that enables quick operation. FIG. 11 shows an example of a text input system that can be used in the authoring terminals 12-1 to 12-N. In this input system, a character to be input is designated by a combination of a key pressed in the first digit and a key pressed in the second digit. For example, when inputting the character “a” at the upper left, the tone signal generator 122 presses the “1” button as the first digit, and then presses the “1” button as the second digit. . After the free input text data is input in this way, when the button corresponding to the time in seconds for displaying the free input text data is further pressed using the tone signal generator 122, the corresponding operation is performed. A timed tone signal is generated.

  By the above operation, the data type of the image data, the fixed text data, the free input text data, the vibrator control data and the liquid crystal backlight control data, the contents to be displayed for the display data, the time for displaying the display data, or Each tone signal indicating the time when control by the control data is performed is generated, and these tone signals are transmitted from the authoring terminal 12-1 to the data creation server 47 via the telephone network 9. This tone signal is transmitted to the data creation server 47 as a transmission signal combined with the voice signal input from the receiver 121. The transmission / reception / control unit 571 of the data creation server 47 receives this transmission signal and digitizes it. The signal recognition unit 572 extracts a tone signal from digitized audio data using a filter that selects and passes audio having a frequency near the tone signal, and detects whether there is a tone signal. (Step S85). When the tone signal is detected, the signal recognizing unit 572 identifies the button of the tone signal generation device 122 corresponding to each tone signal and the time when the tone signal is received, and presses the button at the authoring terminal 12-1. The button information including the character attached to the selected button and the time when each button was pressed is transmitted to the display / control data creation unit 576 (step S85-2).

  On the other hand, the transmission / reception / control unit 571 delivers the digitized audio data to the audio data creation unit 575. Alternatively, the audio data from which the tone signal component is removed or attenuated by the signal recognition unit 572 may be transmitted to the audio data creation unit 575. The audio data delivered to the audio data creation unit 575 is output in a single audio file, for example, every 15 seconds, which is a preset time interval, according to the elapsed time measured by the timer unit 573. When the elapse of the predetermined time is determined in step S84 after the start of the input of the audio data, in step S86, unit reproduction data which is audio data for the predetermined time is generated by the audio data generation unit 575.

  When the unit reproduction data is created in this way, the display / control data creation unit 576 analyzes the button information transmitted from the signal recognition unit 572 within a predetermined time corresponding to the unit reproduction data in step S87, Create display and control data. The display / control data creation unit 576 first identifies the data type using the button information for the first predetermined number of characters corresponding to the data type designation tone signal among the button information generated by the signal recognition unit 572. For example, image data when “# 0” is pressed, vibrator control data when “# 1”, liquid crystal backlight control data when “# 2”, fixed text data when “# 3” Identifies that has been inserted. For example, when the first two characters of the button information are character strings other than “# 0”, “# 1”, “# 2”, and “# 3” indicating the data type, the inserted data is free. Identify input text data.

  When the inserted data is image data or fixed text data, the display / control data creation unit 576 then displays button information for a predetermined number of characters corresponding to the data designation tone signal, following the button information for designating the data type. To identify the contents of each data. Specifically, the button information is inserted by matching the button information stored in advance in the image data storage unit 578 and the text data storage unit 579 in association with the image data and the fixed text data. Identify the data that should be.

  In the case where the inserted data is free input text data, since the data type designation tone signal is not used in this embodiment, the display / control data creation unit 576 has a predetermined indication indicating the end of input from the beginning of the button information. The contents of the data are specified using the button information up to the button information. Specifically, the text to be inserted is input from the input button information by using the information of the correspondence between the button information and the characters as shown in FIG. Identify.

  In the case of image data, fixed text data, and free input text data, after identifying the data content, in the case of vibrator control information and liquid crystal backlight control information, after identifying the data type, the signal recognition unit 572 The relative start time and end time of each data are calculated. Here, the relative start time is received by the data creation server 47 as data type designation tone signal of image data, vibrator control data, liquid crystal backlight control data and fixed text data, or data designation tone signal of free input text data. It is determined based on the set time. The relative end time is calculated by adding the time designated by the time designation tone signal for each data to the relative start time. That is, in the case of image data, fixed text data, and free-input text data, the data type is specified in the case of button information for a predetermined number of characters following the button information specifying the data contents, vibrator control information, and liquid crystal backlight control information. The time designated by the time designation tone signal is specified from the button information for a predetermined number of characters following the button information to be performed, and added to the relative start time to calculate the relative end time.

  An example of calculating the relative start time and end time will be described. When there is unit reproduction data corresponding to a period of 1500 to 3000 milliseconds since the start of content creation, 1620 seconds from the start of content creation. When a data type identification signal indicating image data is received when the time has elapsed and the period of the image data is specified as 180 milliseconds, the relative start time of the image data is 120 milliseconds from 1620-1500 = 120. The relative end time is calculated as 300 milliseconds from 120 + 180 = 300.

  Thereafter, the display / control data creation unit 576 corresponds to the image data, the fixed text data, the free input text data, the vibrator control information, and the liquid crystal backlight control information received within a predetermined time corresponding to the unit reproduction data. A display / control data file including the relative start time or end time attached is created.

  The unit reproduction data created in step S86 and the display / control data file corresponding to the unit reproduction data created in step S87 are combined into one distribution data by the distribution data creation unit 577 in step S88. . At this time, the distribution data creation unit 577 adds, to the created distribution data, the program ID of the content input in advance by the content creator, and unit reproduction data for which the distribution data is created every predetermined time from the start of the program. A division number indicating what number corresponds is assigned. This distribution data is transmitted to the conversion server 43 by the transmission / reception / control unit 571 in step S89.

  Thereafter, when a predetermined button of the tone signal generation device 122 is pressed, a tone signal corresponding to the predetermined button is transmitted from the authoring terminal 12-1 to the data creation server 47, and the transmission / reception / control unit 571 creates content in step S90. Determine the end of processing. In FIG. 8, after it is determined in step S84 that the predetermined time has elapsed, after steps S86 to S89 are executed, it is determined in step S90 whether or not the content creation is finished, and the creation is finished. In the content creation processing of this embodiment, the recording of audio data and the measurement of elapsed time started in step S83 are the start of content creation. The process is continuously executed without being interrupted in steps S86 to S89. The determination of whether the predetermined time has elapsed in step S84 is based on the measurement of the elapsed time continuously performed by the timer unit 573 as described above, and it is determined that step S86 should be started each time the predetermined time has elapsed. Is. The processes in steps S86 to S89 are executed in parallel with the recording of the audio data and the measurement of the elapsed time every time a predetermined time elapses, and the created distribution data is sequentially transmitted to the server system group 13. The input of display / control data in step S85 can be executed at any timing from the start to the end of content creation.

  FIG. 9A is a flowchart showing an example of the flow of content conversion / storage processing for converting and storing the content created in this way in the server system group 13. This processing is started when the transmission / reception / control unit 531 of the conversion server 43 receives the first predetermined period of the content created by the data creation server 47 in step S1001.

  In step S1002, the transmission / reception / control unit 531 operates the content conversion unit 532 and uses the data stored in the mobile phone type information storage unit 533 to convert the unit reproduction data included in the received content into the mobile phone 15 Converted to model-specific unit reproduction data suitable for reproduction in each model of -1 to 15-M. By this conversion, the model-specific unit playback data, the display data or control data used on the mobile phone during playback of the unit playback data, the program ID of the program included in the content, and the data from the beginning of the program Distribution data including a division number indicating whether the time corresponds to the first predetermined time is created. The conversion server 43 transmits this distribution data to the distribution A server 44 and the distribution B server 45 in step S1003.

  The transmission / reception / control units 541 and 551 of the distribution A server 44 and the distribution B server 45 receive the distribution data from the conversion server 43 and store them in the content storage units 543 and 553 in step S1004. As a result, the content created by the data creation server 47 is held in the distribution A server 44 and the distribution B server 45 in a state where the content can be distributed to the mobile phones 15-1 to 15-M.

  Next, FIG. 9B is a flowchart illustrating an example of the flow of content distribution management processing when the distribution management server 42 determines that the content can be distributed. The distribution availability monitoring unit 522 of the distribution management server 42 periodically monitors at least one of the distribution A server 44 and the distribution B server 45, and distribution data of a new program is stored in the content storage unit of the monitored server. When it is detected that the program is available, it is determined that the program can be distributed. If the distribution availability monitoring unit 522 performs such monitoring in step S1005 and determines that a new program can be distributed, in step S1006, the distribution availability monitoring unit 522 displays the program of the program in the distribution management DB 524. For example, “1”, which is a value indicating that distribution is possible, is set in the flag 613 corresponding to the ID 610. Further, the distribution availability monitoring unit 522 of the distribution management server 42 can distribute the content to the distribution A server 44, the distribution B server 45, and the error distribution server 46 at the same time or after the change of the flag 613 of the distribution management DB 524. A distribution start signal is sent to notify that there is. Then, the error distribution end determination unit 563 of the error distribution server 46 that has received the distribution start signal determines in step S1107 that distribution of error notification content described later should be ended.

  FIG. 10 is a flowchart showing an example of a flow of content distribution processing for distributing content to mobile phones 15-1 to 15-M in content distribution system 10. In this process, for example, a dedicated application installed in the mobile phone 15-1 that is one of the mobile phones 15-1 to 15-M is activated, and a content distribution request operation is performed on the displayed distribution request screen. Start with. Then, in step S1101, a content distribution request is transmitted from the mobile phone 15-1 to the authentication server 41. The transmission / reception / control unit 511 of the authentication server 41 receives the content distribution request in step S1102, and operates the user authentication unit 512 to authenticate the user. Specifically, it is confirmed that the user ID included in the content distribution request is registered in the user DB 513 and is within the contract period. If the authentication in step S1102 fails, the process returns to the beginning, and the distribution request screen is displayed again on the display device 153 of the mobile phone 15-1.

  When the user authentication in step S1102 is successful, the transmission / reception / control unit 511 of the authentication server 41 inquires the distribution management server 42 whether or not the program requested by the user is viewable in step S1103. Send the availability inquiry signal. In step S1104, the transmission / reception / control unit 521 of the distribution management server 42 receives the viewing permission / inquiry inquiry signal, and operates the viewing permission / non-permission determination unit 523 to determine whether or not the program can be viewed. Specifically, the distribution management DB 524 is searched using the program ID transmitted from the authentication server 41 as a key, and it is determined whether or not a flag indicating that distribution is possible is set in the flag 613 corresponding to the designated program ID. Various factors can be used as the reference for determining whether or not to view. For example, since the number of users who can simultaneously distribute one program is usually limited due to performance limitations of the distribution server, the number of users who want to view a specific program is within the limited range. It is conceivable to allow viewing only to the user. It is also possible to permit viewing of content only to users who use a specific model by using the model information included in the content distribution request from the mobile phone 15-1.

  For example, when the user makes a distribution request before starting the distribution of the program, when the user cannot view the program, the distribution management server 42 indicates to the authentication server 41 that the viewing is impossible in step S1105. Send. Then, in step S1106, the transmission / reception / control unit 511 of the authentication server 41 that has received the non-viewable signal sends the address information of the error distribution server 46 to the user's mobile phone 15-1, specifically, the error distribution server 46. And a division number of distribution data to be requested first by the mobile phone 15-1, for example, “0” is notified. Therefore, in step S1107, the cellular phone 15-1 makes a data request by an http request to the error delivery server 46 using the received URL and division number. In the content storage unit 564 of the error delivery server 46, error notification content including an error message indicating that the program cannot be viewed is created and stored in advance for each model of the mobile phone. In step S1108, the transmission / reception / control unit 561 of the error distribution server 46 that has received the data request from the user operates the content distribution unit 562 and causes the cellular phone 15-1 to include the model included in the data request from the cellular phone. Response data including error notification content corresponding to the information is distributed. As this error notification content, for example, it is conceivable to use image data displaying a message such as “Sorry, this content cannot be viewed at present”.

  Thereafter, when the user does not specify termination of the dedicated application to the mobile phone 15-1, the data request to the error delivery server 46 in step S1107 and the delivery of the error notification content in 1108 are repeated.

  After that, when the content creator performs an operation for starting the creation of the content of the program that the user desires to view using any of the authoring terminals 12-1 to 12-N, the authoring used in step S1109. The terminal 12-1 and the like start generating the audio signal and the tone signal, and in step S1110, a transmission signal including the audio signal and the tone signal is transmitted to the data creation server 47 to create content. Steps S1109 and S1110 correspond to the content creation process shown in the flowchart of FIG. Subsequent to the content creation processing, the content conversion / storage processing shown in FIG. 9A is performed, and the distribution data is stored in the content storage units 543 and 553 of the distribution A server 44 and the distribution B server 45. At the same time, the content distribution management process shown in FIG. 9B is executed, and the error distribution end determination unit 563 of the error distribution server 46 determines that the error distribution should be ended. Therefore, when the transmission / reception / control unit 561 of the error delivery server 46 receives the data request from the mobile phone 15-1 in step S 1112, the communication with the error delivery server 46 is made to the mobile phone 15-1 in step S 1113. The response data including information for instructing the authentication server 41 to make a content distribution request is transmitted again.

  The mobile phone 15-1 that has received the response data transmits a content distribution request to the authentication server 41 again in step S1114. The transmission / reception / control unit 511 of the authentication server 41 performs user authentication similar to step S1102 in step S1115, and then transmits a viewing permission inquiry signal similar to step S1103 to the distribution management server 42 in step S1116. In step S <b> 1117, the viewing permission determination unit 523 of the distribution management server 42 determines whether the program can be viewed as in step S <b> 1104. In this case, since the flag 613 corresponding to the program in the distribution management DB 524 is set to a value indicating that distribution is possible as described above, the viewing availability determination unit 523 determines that the program is viewable, and transmits and receives In step S1118, the control unit 521 transmits a signal indicating that viewing is possible to the authentication server 41.

  When the transmission / reception / control unit 511 of the authentication server 41 receives the viewable signal in step S 1119, the transmission / reception / control unit 511 is a distribution server that distributes content to the mobile phone 15-1. The URL and the division number of the distribution data to be requested first by the mobile phone 15-1, for example “0”, are transmitted. In step S1120, the cellular phone 15-1 transmits a data request to the distribution A server 44 using the received URL and division number.

  Upon receiving this data request in step S1121, the transmission / reception / control unit 541 of the distribution A server 44 operates the content distribution unit 542 to the mobile phone 15-1 for the program stored in the content storage unit 543. Among the distribution data, response data including the distribution data corresponding to the model of the cellular phone 15-1 and including the division number specified in the data request is transmitted. At this time, the distribution A server 44 calculates the distribution data to be requested next by the mobile phone 15-1 calculated by incrementing the program ID and the distribution data division number requested from the mobile phone 15-1. Are included in the response data and transmitted. Upon receiving such response data, the cellular phone 15-1 transmits a data request including the program ID and the division number included in the response data when transmitting the next data request to the distribution A server 44. . When the distribution A server 44 receives such a data request, the distribution A server 44 operates the content distribution unit 542 to transmit the distribution data of the requested division number of the program stored in the content storage unit 543 to one request. Deliver one by one.

  In addition, since the mobile phones 15-1 to 15-M reproduce the content without interruption, the distribution data to be reproduced next to the distribution data being reproduced can be stored in a buffer provided in the storage device 151. . When there is no distribution data in the buffer, the cellular phones 15-1 to 15-M transmit a data request to the distribution A server 44. When the distribution data is stored in the buffer, the data request is executed at a predetermined timing after the reproduction of the distribution data being reproduced is finished and the reproduction of the distribution data in the buffer is started.

  The timing of the data request may be after the start of reproduction of distribution data, for example, after the buffer is emptied, and at a timing at which data can be written to the buffer before the distribution data corresponding to the data request is received. I just need it. By making a data request at a predetermined timing after the start of reproduction in this way, the distribution server leaves a predetermined time or more after the data request until the next data request arrives. Can be received from the data creation server 47 and stored. Therefore, distribution data can be reliably prepared when a data request is made from a mobile phone. In addition, since the distribution data can be reliably prepared as described above, it is possible to appropriately suppress the data request from the mobile phone even though the data to be distributed is not prepared.

  When content creation at the authoring terminal 12-1 is completed in step S1122, and the distribution data having the last division number of the program is transmitted in response to the data request from the cellular phone 15-1 in step S1123, the distribution A server 44 In step S1124, the response data including the distribution data is transmitted including information instructing to terminate the communication with the distribution A server 44 and request the content distribution to the authentication server 41 again. The mobile phone 15-1 that has received the response data transmits a content distribution request to the authentication server 41 as in step S1101. Thereafter, processing similar to that after step S1102 is performed.

  12 to 14 show data exchanged between the cellular phones 15-1 to 15-M and the distribution A server 44, the distribution B server 45, and the error distribution server 46 in the content distribution system 10 using the http protocol. It is a figure which shows a format.

  FIG. 12 is transmitted at the time of a data request to the distribution A server 44, the distribution B server 45, and the error distribution server 46 from the cellular phones 15-1 to 15-M, for example, steps S1107, S1112, S1120, and S1123. It is a figure which shows the format of the request data 1300. The request data 1300 includes a program ID 1301, a server-side designated character string 1302, and a version number 1303. The program ID 1301 is a unique character string for identifying a program for which distribution is requested, and the server-side designated character string 1302 is a character string necessary for processing in the distribution server. A division number indicating what number of distribution data is requested is included. The version number 1303 indicates the version of the dedicated application installed in the mobile phones 15-1 to 15-M that transmit the request data 1300.

  FIGS. 13 to 14 show, for example, steps S1108, S1113, S1121 and S1124 from the distribution A server 44, the distribution B server 45 and the error distribution server 46 according to the request data shown in FIG. It is a figure which shows the format of the response data 1400 used when replying to ~ 15-M. The response data 1400 includes an error code 1401, a program ID 1402, a server side designated character string 1403, a program name 1404, a header portion 1411 including the number of data items 1405, and data storage offsets 1406-1-1 to 1406-L (L is an arbitrary number). Natural number), data lengths 147-1 to 1407-L, data types 1408-1-1 to 1408-L, and L data portions 1412-1 to 1412-L including actual data 1409-1 to 1409-L Including. The error code 1401 indicates the processing state of the request data 1300 in the distribution A server 44, the distribution B server 45, and the error distribution server 46. For example, “0” indicates normal, “1” indicates error, If “2”, the mobile phones 15-1 to 15 -M that have received the response data 1400 terminate communication with the distribution A server 44, distribution B server 45, and error distribution server 46, and return the contents to the authentication server 41. Indicates that a delivery request should be made. If the error code 1401 is set to “1” indicating an error, for example, the response data 1400 does not include data after the program ID 1402. Next, the program ID 1402 is an ID for identifying a program included in the response data 1400, and an ID common to the program ID 1301 included in the request data 1300 is used. The server-side designated character string 1403 is a character string necessary for processing in the distribution server, and specifically includes a distribution data division number to be requested next. The program name 1404 is the name of a program included in the response data 1400, and the data number 1405 is the number of data stored in the data parts 1412-1 to 1412-L. For example, when only one of the data parts 1412-1 and 1412-2 exists in one response data, the data number 1405 is “2”.

  The data parts 1412-1 to 1412 -L store audio data, image data, character data, vibrator control information, and liquid crystal backlight control information that are distribution data to the mobile phones 15-1 to 15 -M. However, the response data 1400 does not necessarily include all of these five types of data, and may include a part thereof. Further, each type of image data, character data, vibrator control information, and liquid crystal backlight control information may include one data or a plurality of data.

  The data storage offsets 1406-1 to 1406-L are offset values of the head data of the data parts 1412-1 to 1412 -L, and the data lengths 1407-1 to 1407 -L are those of the data parts 1412-1 to 1412 -L. This is the data length, and data types 1408-1 to 1408 -L indicate the types of data stored in the actual data 1409-1 to 1409 -L. The data types 1408-1 to 1408 -L are, for example, “0” if the data stored in the actual data 1409-1 to 1409 -L is audio data, “1” if the data is image data, and character data. If it is, “2” can be set, “3” if it is vibrator control information, and “4” if it is liquid crystal backlight control information. In the actual data 1409-1 to 1409 -L, audio data, image data, character data, vibrator control information, and liquid crystal backlight control information, which are contents, are stored in a format described later.

  FIG. 14 is a diagram showing a format of data stored in the actual data 1409-1 to 1409 -L of the response data 1400, where (a) in FIG. 14 is audio actual data 1500, and (b) is actual image data. Data 1510, (c) shows the format of the actual character data 1520, (d) shows the actual data 1530 of the vibrator control information, and (e) shows the format of the actual data 1540 of the liquid crystal backlight control information. The actual audio data 1500 includes a special operation flag 1501, a reproduction time 1502, and audio data 1503. The special operation flag 1501 is a flag for setting a special operation, and the reproduction time 1502 indicates the reproduction time of the data stored in the audio data 1503 in units of milliseconds, for example. The audio data 1503 stores audio data that can be reproduced by the mobile phones 15-1 to 15-M in the mld format or the mmf format.

  The actual image data 1510 includes a relative start time 1511, an operation flag 1512, a layer designation 1513, an image type 1514, and image data 1515. The relative start time 1511 indicates the time at which the display of the image data 1515 starts or ends as a relative time in milliseconds from the reproduction start time of the audio data 1503 included in the same response data 1400. The operation flag 1512 is a flag for designating the “start” or “end” operation of the image display. For example, when the operation flag 1512 is “0”, the image display starts, and when the operation flag 1512 is “1”. It is possible to set the display to end. As an example, when “300” is stored in the relative start time 1511 and “0” is stored in the operation flag 1512, the mobile phones 15-1 to 15 -M are received when 300 milliseconds have elapsed from the start of reproduction of the audio data 1503. The display of the image data 1515 is started on the display device 153. In this case, the same response data 1400 or the response data after the response data in the same program includes actual image data including an operation flag indicating “end” of the display. The image display is terminated at the specified relative time. The layer designation 1513 indicates a layer on which the image data 1515 is to be displayed when a plurality of images are displayed simultaneously on the display device 153. The image type is a field for designating the data format of the image data 1515 such as the jpg format or the gif format. The image data 1515 stores image data to be displayed on the display devices 153 of the mobile phones 15-1 to 15-M.
