  An embodiment when the present invention is applied to an IP videophone will be described with reference to FIG.

  The IP videophone 10 includes a mail transmission / reception unit 11 and a mail management unit 12 and an answering machine control unit 13 for realizing an answering machine function. The mail transmission / reception unit 11 and the mail management unit 12 may be collectively referred to as a mail control unit for realizing a mail function. In addition to the line control unit 14, the IP video phone 10 also includes an input unit 15 using a keyboard or the like, a display unit 16 using a liquid crystal display device, and a storage unit 17. The storage unit 17 includes at least an absence data storage unit 17-1, a mail data storage unit 17-2, and a mail address storage unit 17-3 as elements indispensable for realizing functions to be described later according to the present embodiment. The control program storage unit 17-4 is included, but these storage areas are only a part of the storage unit 17.

  The IP video phone 10 further includes a CPU 18 as a control unit for controlling the entire apparatus. The CPU 18 reads out and executes the control program stored in the control program storage unit 17-4, thereby cooperating with the mail control unit (the mail transmission / reception unit 11 and the mail management unit 12) and the answering machine control unit 13. Although the operation to be described later is realized, the following description will be made with the CPU 18 omitted. FIG. 1 shows only components necessary for realizing the functions described later in the present embodiment. Needless to say, the present invention is not limited to such an IP video phone 10 alone.

  With reference also to FIG. 2, the general function of the IP videophone 10 having the configuration of FIG. 1 will be described.

  FIG. 2 shows that the IP videophone 10 stores voice and video from a partner terminal 101 (regardless of fixed type or portable type) having a videophone function as answering data, and the stored answering data is separated. The flow of operation when receiving by e-mail with the portable terminal 107 is shown. However, the blocks shown in the IP video phone 10 have a function block meaning necessary for explaining the operation rather than showing the constituent elements. Further, another portable terminal 107 is not limited to one, and may be a fixed type. Another portable terminal 107 may also have only a mail function.

  In FIG. 1 and FIG. 2, when the answering machine control unit 13 of the IP videophone 10 receives a call from the partner terminal 101 via the line control unit 14 during the answering machine function setting, the voice and video are used as answering data. The data is stored in the recorded message data storage unit 17-1. Note that the recorded date / time information, information on whether the recorded message data is only audio or with video, telephone number information of the partner terminal 101, and the like are attached to the recorded message data.

  The recorded message data stored in the recorded message data storage unit 17-1 can be reproduced by a predetermined instruction from the input unit 15, displayed on the display unit 16, or output from a speaker (not shown).

  The recorded message data can also be attached to a mail using the mail function of the mail transmission / reception unit 11 and the mail management unit 12 and automatically transmitted to another portable terminal 107 via the line control unit 14. At this time, in the text of the mail, the date and time information stored in the answering record data, the information on whether the answering record data is only voice or video, and the telephone number information of the partner terminal 101 Etc. are automatically written. This automatic writing can be performed by the mail management unit 12. If the IP video phone 10 has a telephone book function, the name of the owner of the partner terminal 101 is automatically written in the mail text when the telephone number of the partner terminal 101 is registered in the telephone book function.

  In the mail address storage unit 17-3, the mail address of the mobile terminal 107 that the user wants to send the recorded message data by e-mail when stored, and the format format of the data that can be played back by the mobile terminal 107 are registered in advance. Registration is performed in the CSV file format, and data management is performed. Regardless of whether it is a mobile terminal or a fixed terminal, registration can be performed for a plurality of devices. As shown in FIG. 3, as an example, the name of the communication service company, e-mail address, e-mail to which the mobile terminal to which you want to send e-mail Data format format (audio format, video format) at the time of sending is managed in a table format.

  Based on such pre-registration information, if the format format of the IP videophone 10 and the portable terminal 107 to which the mail is sent is the same, the voice mail data indicating that the voice mail data is to be sent is included in the voice mail data. And (date / time information storing the answering record data + information whether the answering record data is only voice or with video + phone number information of the partner terminal 101) (hereinafter, sometimes referred to as additional information) is attached, It is stored in the mail data storage unit 17-2 and transmitted to the portable terminal 107 as mail data.

  On the other hand, if the format of the IP videophone 10 and the portable terminal 107 to which the mail is sent is different, the format is converted, and the converted message recording data and additional information are attached to the mail body, and the mail data storage unit 17- 2 and transmitted to the portable terminal 107 as mail data. The format conversion is performed by the format conversion unit 13-1 in the answering machine control unit 13.

  As described above, if the IP videophone 10 is a portable terminal whose mail address is registered in the mail address storage unit 17-3, the stored answering machine data is automatically transmitted to the portable terminal by mail. If the portable terminal registered with the e-mail address is held in the storage unit 17-3, the contents of the recorded message data can be known even when the user is away from home. In addition, by sending the answering data stored and received by the IP videophone with an IP video phone whose communication charge is lower than the call charge of the mobile phone or fixed phone to the mobile terminal by mail, the answering machine data is cheap at the mobile terminal side. Can receive. Furthermore, by sending the message recording data as an attachment to an e-mail, the message recording data can be received even by a PC (personal computer) or a portable terminal having no telephone function. In addition, since a plurality of terminals (fixed terminals such as PCs and portable terminals) that send mail can be registered, it is possible to select a terminal that sends mail according to the situation.

  The case where the first embodiment of the present invention is applied to the IP telephone 10 as described above will be described. Unless otherwise specified, the following explanation is about sending message recording data attached to an e-mail, and is different from normal e-mail sending.

  In FIG. 2, the IP videophone 10 receives a call from the partner terminal 101. At this time, it is assumed that IP videophone 10 is in the setting state of the answering machine function. In the mail address storage unit 17-3, the mail address 104 of the portable terminal 107 to which the recorded message data is attached and sent, and the data format that can be reproduced by the portable terminal 107 are registered in advance.

  As described above, the mail address of the terminal to which mail is sent is managed by a management table (FIG. 3) prepared in advance, and the mail addresses of one or more terminals (fixed terminal, mobile terminal) are registered. . As a result, not only one device but also a plurality of devices and all terminals with registered email addresses can be sent together at the time of mail transmission. Also, a format that can be played back by the terminal that sends the mail is registered by setting from the outside. If not given from the outside, as will be described later, when a mail address is registered, it is automatically searched from the end of the mail address and registered in the management table (FIG. 3).

  The telephone call received from the partner terminal 101 is converted into data that can be played back by the IP videophone 10 and stored in the recorded message data storage unit 17-1 as recorded message data 103. However, this data can be reproduced and confirmed only by the IP videophone 10 as it is, and cannot be reproduced and confirmed by a terminal having a different format. Therefore, using the answering machine function of the IP videophone 10, that is, the answering machine control unit 13, this data is registered in the management table (FIG. 3) and is in a format that can be reproduced by the portable terminal 107 that sends the mail. The format conversion 105 is performed, and the format-converted data is also stored as the recorded message data 103 in the recorded message data storage unit 17-1.

  Subsequently, the mail management unit 12 creates mail data 106 based on the stored recorded message data 103 and sends the mail data 106 to the mobile terminal 107 via the mail transmission / reception unit 11 and the line control unit 14. As a result, as long as the portable terminal 107 that receives the mail is possessed, the recorded data 103 of the IP videophone 10 can be received, reproduced, and confirmed even when away from home.

  Here, since the terminal that receives the call (the terminal that performs voice mail recording) is the IP video telephone 10 that is cheaper than a mobile phone or the like, it costs more than calling the mobile terminal 107 directly from the counterpart terminal 101. Will be cheaper.

  Furthermore, since the mail data 106 is sent, it is possible to receive, play back and confirm the recorded message data 103 even if the portable terminal 107 does not have a telephone function. At this time, the packet fee for receiving data by e-mail can be received without worrying about the cost if it is a flat rate system.

  Next, the operation of the first embodiment will be described with reference to FIGS.

  FIG. 4 shows the processing flow of the recorded message data of FIG.

  In the processing of the answering machine data, the terminal 302 (IP videophone 10 in FIG. 2) that receives the call is set to the answering machine in advance.

  After the answering machine is set, the telephone 301 from the other party (the telephone from the partner terminal 101 in FIG. 2) is received by the terminal 302 that receives the telephone call.

  The received telephone information is processed by the answering machine function 303 (answering machine control unit 13 in FIG. 1), and converted into information to be written in the mail text.

  The information of the telephone 301 from the other party is divided into a call content 304 and a telephone number 312 of the other party.

  Content analysis 305 is performed in order to transfer the mail with an appropriate amount of data by changing the format depending on whether the data of the call content 304 is only audio or with video. Content analysis 305 is performed and converted into audio data or video data to create content data 306.

  Even if this content data 306 is still received by another portable terminal, there is a possibility that it cannot be reproduced or confirmed. Therefore, it is necessary to convert the content data 306 into a format suitable for each terminal to which mail is to be transferred.

  FIG. 6 shows a data format process performed in order to make it possible to reproduce data on a terminal different from the terminal (302).

  The answering machine control unit 13 (FIG. 1) registers the e-mail address 502 of the e-mail receiving terminal (the portable terminal 107 in FIG. 2) registered in advance in the e-mail transmitting terminal 501 (the IP videophone 10 in FIG. 2). From the management table (mail address storage unit 17-3 in FIG. 1) registered in advance as shown in FIG. 3, the format format suitable for the terminal is searched 503, and the obtained format format 504 is used. The video / audio data 505 is format-converted 506, and the format-converted data is created as sending data 507.

  As described above, this format format is registered in the management table together with the mail address in advance, and when used, the format format is searched from the mail address, and data conversion is performed based on the obtained format format (FIG. 1). 13-1) can increase the types of data that can be exchanged with other terminals by e-mail.

  As a method of registering the format, a user input screen that allows external input of the information shown in FIG. 3 is prepared, or a method of processing what is stored in the CSV format as an internal process can be considered. A CSV format can be created and incorporated into the apparatus via an external interface such as a LAN.

  Returning to FIG. 4, when the content data 306 of the recorded message is reproduced and confirmed by the terminal that receives the mail, this format processing is used.

  The format of the terminal that receives the recorded message data that has been registered together with the email address from the email address 309 of the terminal that receives the recorded message data in the email address information 308 of the terminal that receives the recorded message data (mobile terminal 107 in FIG. 2). The format 310 is searched, the content data 306 is formatted in the obtained format, and the formatted content data 307 is created.

  On the other hand, the telephone number 312 of the other party (the partner terminal 101 in FIG. 2) uses the telephone book function 311 when the terminal 302 (IP videophone 10 in FIG. 2) receiving the telephone has the telephone book function 311. The telephone number analysis 313 is performed. If the telephone number is registered, the registered name and the telephone number are combined to obtain a number analysis result 314.

  The answering machine control unit 13 combines the formatted content data 307, the number analysis result 314, and the mail address 309 of the terminal that receives the recorded message data into the answering machine data 315, and temporarily stores it in the recorded message data storage unit 17-1. save. Actually, in addition to the analysis result 314 of the number, as described above, the answering record data 315 includes (the date / time information on which the answering record data is stored + information on whether the answering record data is only audio or with video) ) Is also added.

  When there are a plurality of e-mail addresses of terminals that receive the recorded message data, that is, when there are a plurality of terminals that transfer e-mail messages, the format 310 analyzed from the e-mail address for each e-mail address 309 of the terminal that receives the recorded data Is used to format the content data 306 into the formatted content data 307, and a plurality of answer records 315 are created.

  FIG. 5 shows the processing flow of the mail data of FIG.

  In the processing of the mail data in FIG. 5, the contents 410 of the created message recording data 401 are formatted by the mail function 402 (mail management unit 12 in FIG. 2) for each terminal to which the message recording data is sent, It is divided into the telephone number 404 and registered name 405 of the terminal (101 in FIG. 2) and the mail address 408 of the terminal to which the recorded message data is sent. The text 403 of the mail includes the telephone number 404 of the other terminal, the registered name 405 if registered in the telephone book (the telephone book function 311 in FIG. 4), and the contents indicating whether the contents of the recorded message data are video or audio. The data analysis result 406 and the date and time when the recorded message data is saved are written. As the attachment 409 of the mail, the data 410 in which the contents of the message recording data are formatted for each terminal is added, the mail address 408 of the terminal to which the message recording data is sent is put in the mail address 407, and the text 403 and the attachment 409 are combined. It is assumed that the answering machine mail (mail data 106 in FIG.
