  The present invention relates to a communication device.

  Conventionally, a system has been proposed in which a server capable of providing content such as moving images, still images, and music and a client capable of reproducing such content are connected via a network (see, for example, Patent Document 1). ).

If this type of system is used, the content provided from the server side can be reproduced on the client side.
JP 2004-128597 A

  By the way, a telephone having a so-called answering machine function is configured to record an incoming message (ICM; InComing Message) transmitted from a calling side device when an incoming call is received when a user is absent.

  However, since the incoming message recorded by this type of telephone has been conventionally converted into data by an encoding method considering only that it can be reproduced by the telephone, the recorded incoming message is described in the technique described in Patent Document 1. Even if the message is provided to the client side using the client, the client side provided with the incoming message cannot reproduce the incoming message.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a communication device capable of constructing a highly convenient communication system.

Hereinafter, the configuration employed in the present invention will be described.
The communication device of the present invention is configured to be able to communicate with a first communication device having a telephone function via a first network and to be able to communicate with a second communication device having a sound reproduction function via a second network. A storage device for storing an incoming message transmitted from the first communication device as first-format audio data that cannot be reproduced by the second communication device; and first-format audio data Is converted to second format audio data reproducible in the second communication device, and the second format audio data converted by the conversion unit is converted to the second format via the second network. and audio data transmission means for transmitting to the communication device, and a detectable detection means that said second communication device is connected to the second network, and the converting means, the second communication Characterized in that the location is on condition that that is connected to the second network has detected that the detecting means, and the audio data of the first format is configured to convert the audio data of the second format And

  According to the communication device configured as described above, the incoming message transmitted from the first communication device is stored in the storage means as the first format audio data that cannot be reproduced by the second communication device. The audio data in one format is converted into audio data in the second format, and the audio data in the second format is transmitted to the second communication device. Therefore, unlike the case where the first format audio data is transmitted as it is to the second communication device, the second communication device can reproduce the second format audio data, and the recorded incoming data can be reproduced. The message can be freely reproduced by the communication device that the user wants to reproduce. Therefore, a highly convenient communication system can be constructed by using the communication apparatus having such a configuration.

In addition, according to the communication device of the present invention , the recorded incoming message is converted by the user into the second format audio data on condition that the second communication device is connected to the second network. It can be freely played back on the communication device to be played back. Furthermore, for example, when the second communication device is not connected to the second network, the conversion work that may be wasted can be reduced, the load is reduced, and it is necessary for the conversion. There is no waste of resources.

  When it is detected that the second communication device is connected to the second network, the first format audio data is converted to the second format audio data. Therefore, if a voice transmission request is transmitted from the second communication device, it is possible to immediately respond to the request, and more than what performs conversion on condition that the voice transmission request has been transmitted from the second communication device, The second format audio data can be quickly provided to the second communication device.

  In the communication apparatus of the present invention, the storage unit is further configured to store the audio data in the second format, and the audio data transmission unit is stored in the storage unit. The voice data may be transmitted to the second communication device. In this case, whether or not the second communication device detected by the detection means is disconnected from the second network is determined. And determining means for determining, and deleting means for deleting the audio data of the second format from the storage means on condition that the determining means determines that the second communication device has been disconnected. .

  According to the communication device configured in this way, when the second communication device is disconnected from the second network, the second format audio data is deleted from the storage means, so that the second communication device is connected to the second network. Even if it is not certain whether or not the connection will be made again, the second-format audio data will not remain in the storage means.

  Furthermore, the communication apparatus of the present invention may include a synthesizing unit that synthesizes a plurality of audio data of the second format into one synthesized audio data. In this case, the audio data transmitting unit It is good to be comprised so that the said synthetic | combination audio | voice data synthesize | combined by the synthetic | combination means may be transmitted to a said 2nd communication apparatus.

  According to the communication device configured in this way, even when there are a plurality of second-format audio data, one synthesized audio data is transmitted to the second communication device. Can be reproduced simply by designating one synthesized voice data, without having to designate each of the plurality of second format voice data one by one.

Next, embodiments of the present invention will be described with some specific examples.
(1) First Embodiment First, a first embodiment will be described.

[Entire system configuration]
FIG. 1 is a block diagram showing a network system including an MFP (Multi Function Product) corresponding to an embodiment of the present invention.

  The network system shown in FIG. 1 includes an MFP 1, a router 2, a television 3, an audio device 4, and the like, and these devices can communicate with each other via a LAN (Local Area Network) 5.

Either one of the wired network device group and the wireless network device group may be employed, or if there is a device that relays between the wireless network and the wired network, both may be employed in a mixed manner. .

  The Internet line 6 and the PSTN line 7 are connected to an IP telephone set 8 and an analog telephone set 9 as communication destination devices, respectively, so that the MFP 1 can communicate with the IP telephone set 8 and the analog telephone set 9. The IP telephone 8 and the analog telephone 9 are devices corresponding to an example of the first communication device referred to in the present invention.

  In addition, the Internet line 6 and the PSTN line 7 are connected to each other via a gateway, so that even when the MFP 1 uses the IP telephone function, the Internet line 6 and the PSTN line 7 are connected to the PSTN line 7 via the Internet line 6 and connected to the analog telephone 9. Even when the MFP 1 uses the analog telephone function, it is possible to communicate with the IP telephone 8 by connecting to the Internet line 6 via the PSTN line 7. Therefore, even when the MFP 1 has only one of the IP telephone function and the analog telephone function, the MFP 1 can communicate with either the IP telephone 8 or the analog telephone 9.

  Although not shown in FIG. 1, each of the Internet line 6 and the PSTN line 7 is also connected to another line such as a cellular phone network via a gateway. A telephone (for example, a mobile phone) connected to the PC can communicate via the Internet line 6 or the PSTN line 7. In this case, a telephone (for example, a mobile phone) connected to another line is also a device corresponding to an example of the first communication device in the present invention.

  Among the devices described above, the MFP 1, the television 3, and the audio device 4 are all configured as DLNA (registered trademark) guideline compliant devices (hereinafter referred to as DLNA (registered trademark) devices). DLNA (registered trademark) devices include a device that functions as a server and a device that functions as a player. The player transmits video content such as videos and still images and audio content such as music from the server side to the player side. It can be played on the side.

  In order to realize such a function, each DLNA (registered trademark) device has a network communication function for performing communication via the LAN 5. More specifically, when exchanging information and transmitting information between a server and a player, TCP / IP (Transmission Control Protocol / Internet Protocol) is used as a communication protocol, and HTTP (HyperText Transfer Protocol) is used. It is designed to exchange control messages and transfer files.

  Information exchanged or transmitted between devices is described in XML (eXtensible Markup Language), and based on this information, for example, a still image and audio are synchronized and reproduced on the player side, or a text message and audio are transmitted. Controls such as synchronizing and playing on the player side can be implemented.

  Furthermore, each DLNA (registered trademark) device has a UPnP (registered trademark) (Universal Plug and Play) function. When a DLNA (registered trademark) device is connected to the LAN 5, the devices are automatically connected to each other. Configured to recognize.

Note that the communication protocol specifications and UPnP (registered trademark) specifications adopted in these DLNA (registered trademark) are well known, and a detailed description thereof will be omitted.
In the present embodiment, the MFP 1 is configured as a device having both a server function and a player function compliant with DLNA (registered trademark) guidelines. Further, the television 3 and the audio device 4 are configured as devices having a player function conforming to the DLNA (registered trademark) guidelines. Therefore, the television 3 corresponding to the player can reproduce the video and audio distributed from the MFP 1 corresponding to the server. Further, the audio device 4 corresponding to the player can reproduce the sound distributed from the MFP 1 corresponding to the server.

  Unlike the television 3, the audio device 4 does not have a function of reproducing the video distributed from the MFP 1, but has a display function of displaying text data. This display function is used when a text message is delivered together with voice from the MFP 1, and the delivered text message can be displayed on the audio device 4.

[Internal configuration of MFP]
Next, the internal configuration of the MFP 1 will be described.
The MFP 1 includes a CPU 11, ROM 12, RAM 13, panel unit 14, reading unit 15, printing unit 16, LAN control unit 17, NCU 18, FAX MODEM / voice CODEC 19, handset 20, main body speaker 21, and storage unit 22. .

The CPU 11 is a device that executes control and various calculations for each part of the MFP 1 in accordance with a program stored in the ROM 12.
The ROM 12 is a read-only storage device that stores programs and data necessary for controlling the MFP 1.

The RAM 13 is a storage device that stores various types of data that are mainly generated in accordance with calculations performed by the CPU 11.
The panel unit 14 includes an input device configured by keys and a touch panel operated by the user to give various commands to the MFP 1, and a display device such as a liquid crystal display provided for presenting various information to the user. And is composed of.

The reading unit 15 is a device that operates when reading an image using a scanner function, reading a transmission image using a facsimile function, and the like.
The printing unit 16 is an apparatus that operates when printing an image using a printer function, printing a received image using a facsimile function, printing a copy image using a copy function, and the like.

  The LAN control unit 17 performs data communication with other devices (the television 3 and the audio device 4) via the LAN 5, or a device existing on the Internet line 6 side via the LAN 5, the router 2, and the Internet line 6. And a device for performing data communication.

  The NCU 18 is a device for performing communication with other telephones via the PSTN line 7. Note that when the MFP 1 has only the IP telephone function and does not have the analog telephone function, the NCU 18 is unnecessary.

  The FAX MODEM / voice CODEC 19 is a device for performing transmission / reception of facsimile images and voice communication via the PSTN line 7. A voice CODEC provided in the MODEM / voice CODEC 19 (hereinafter referred to as a built-in voice CODEC) is provided corresponding to the telephone function provided in the MFP 1. Specifically, when the MFP 1 has an IP phone function, a μ-Law or A-Law voice CODEC or the like is employed as the built-in voice CODEC. When the MFP 1 has an analog telephone function, an ADPCM voice CODEC or the like is employed as the built-in voice CODEC.

  In this embodiment, since the MFP 1 processes the audio data in the MP3 (MPEG Audio Layer-3) format, the MFP 1 includes the MP3 CODEC of software in addition to the FAX MODEM / audio CODEC 19. However, this MP3CODEC may be configured as hardware as in the FAX MODEM / audio CODEC19.

  The handset 20 is a handset that is used by a user when holding a call using the telephone function of the MFP 1. The handset 20 includes a microphone used for sending a speech and a speaker used for receiving the call. It has been incorporated.

The main body speaker 21 is used when it is desired to listen to the received voice without using the handset 20.
The storage unit 22 is configured by a hard disk device or the like, and stores data of a relatively large size that cannot be stored by the RAM 13 alone, data that is not to be lost even when the power supply is cut off, and the like. When it comes to use. When the storage capacity of the RAM 13 is sufficiently large, large data can be stored in the RAM 13, and therefore the storage unit 22 need not be provided.

[Outline of processing executed by MFP]
Next, an outline of processing executed by the MFP 1 will be described with reference to FIG.
FIG. 2 is a flowchart illustrating an outline of processing executed by the MFP 1. This process is executed immediately after the MFP 1 is activated, and thereafter is repeatedly executed.

  When this process is started, the MFP 1 first determines whether there is an incoming call (S10). Here, if there is an incoming call from another telephone (corresponding to the first communication device in the present invention), it is determined that there is an incoming telephone call (S10: YES). In this case, the incoming telephone call process is executed. (S15). Details of the incoming call processing will be described later. When the incoming call process is completed, the process returns to S10, and the processes after S10 are repeated.

  If it is determined in the process of S10 that there is no incoming call (S10: NO), the MFP 1 determines whether there is an answering machine / music playback instruction (S20). Here, if the user has instructed playback of an incoming message recorded by the answering machine function of the MFP 1 or playback of music stored in the storage unit 22 of the MFP 1 by an operation on the panel unit 14, It is determined that there is an answering machine / music reproduction instruction (S20: YES), and in this case, an answering machine / music reproduction process is executed (S25). Details of the answering machine / music reproduction process will be described later. When the answering machine / music playback process is completed, the process returns to S10, and the processes after S10 are repeated.

  If it is determined in the process of S20 that there is no answering machine / music playback instruction (S20: NO), the MFP 1 determines whether there is a file list transfer request (S30). Here, if a file list transfer request is transmitted from the TV 3 or the audio device 4 to the MFP 1 by performing a predetermined operation on the TV 3 or the audio device 4, it is determined that there is a file list transfer request. (S30: YES), in this case, a file list transfer process is executed (S35). Details of the file list transfer process will be described later. When the file list transfer process is completed, the process returns to S10, and the processes after S10 are repeated.

  If it is determined in the process of S30 that there is no file list transfer request (S30: NO), the MFP 1 determines whether there is a file transmission request (S40). Here, if a user performs a predetermined operation on the television 3 or the audio device 4 and a file transmission request is transmitted from the television 3 or the audio device 4 to the MFP 1, it is determined that there is a file transmission request. (S40: YES), in that case, a file transmission process is executed (S45). Details of this file transmission processing will be described later. When the file transmission process is completed, the process returns to S10, and the processes after S10 are repeated.

  Further, in the process of S40, if it is determined that there is no file transmission request (S40: NO), the MFP 1 executes other processes (S50). As other processing, processing corresponding to various functions provided in the MFP 1, for example, processing related to the scanner function or processing related to the printer function can be considered, but these processing are not directly related to the main part of the present invention. Therefore, further detailed description will be omitted. When the other processes are finished, the process returns to S10, and the processes after S10 are repeated again.

  Note that the processing described above is a flowchart in which determination processing such as S10, S20, S30, and S40 is periodically repeated for the sake of illustration, but equivalent processing may be realized by other methods. I do not care. For example, when an event occurs in which an affirmative determination is made in each process of S10, S20, S30, and S40, each process of S15, S25, S35, and S45 is executed as an interrupt process corresponding to the event. Even with this configuration, a process equivalent to the process shown in FIG. 2 can be realized.

[Incoming call processing]
Next, an incoming call process corresponding to the process of S15 will be described with reference to FIG.
FIG. 3 is a flowchart showing the incoming call process executed by the MFP 1.

  When the incoming call process is started, the MFP 1 first determines whether or not the user answers the telephone (S110). Specifically, the handset 20 provided in the MFP 1 is lifted by the user until a predetermined number of ringing sounds (or until a predetermined time elapses) after an incoming call from another telephone is set. If it is detected by a hook switch that is turned on / off depending on the presence or absence of 20 (or if it is detected that a switch operation has been performed to start a call without lifting the handset 20), in step S110, the user calls the phone. Judgment to go out is made. On the contrary, if a predetermined number of ringing sounds are heard after receiving an incoming call from another telephone without performing an operation for making such a determination (or when a predetermined time has elapsed), in the process of S110, It is determined that the user does not answer the phone.

  If it is determined in the process of S110 that the telephone is answered (S110: YES), the MFP 1 executes a process for making a normal call (S115). In the process of S115, a process for stopping a ringing tone, a process for connecting a line with another telephone, a process for disconnecting a line with another telephone when a call termination operation is detected, and the like are executed. Since this process is a well-known process that is also executed by a general telephone, further detailed description thereof is omitted. Then, when the process of S115 is finished, the telephone call process shown in FIG. 3 is finished.

  On the other hand, if it is determined in step S110 that the telephone is not answered (S110: NO), the MFP 1 reproduces a response message (S120). This response message is sent to another telephone set as a communication destination.

  When the process of S120 is completed, the MFP 1 records the reception date and time (S125). As for the reception date and time, the date and time are obtained from the clock built in the MFP 1, and the voice that reads the date and time is synthesized. The synthesized voice data is stored in the RAM 13, and the reception date and time is recorded.

  Subsequently, the MFP 1 determines whether there is a destination telephone number (S130). In the case of analog telephones, the other party's telephone number is subscribed to a calling number notification service provided by the telephone company (for example, “Number Display (registered trademark)” provided by East Nippon Telegraph and Telephone Corporation or West Nippon Telegraph and Telephone Corporation). If so, the other party's telephone number can be acquired. In the case of an IP phone, the destination telephone number can be acquired from a URI (Uniform Resource Identifier).

  In the process of S130, when there is a destination telephone number (S130: YES), the MFP 1 records the transmission source information (the destination telephone number or the name of the other party) (S135). Specifically, in the case of recording a destination telephone number as transmission source information, a voice that reads out the destination telephone number notified from the transmission source is synthesized. If the name of the other party is to be recorded as the sender information, it is registered in the address book by searching the address book stored in the MFP 1 using the destination phone number notified from the sender as a key. The name is detected and a voice is read out. Then, the synthesized voice data is stored in the RAM 13, whereby the transmission source information is recorded.

  When the process of S135 is completed in this way, the process proceeds to S140. If there is no destination telephone number in the process of S130 (S130: NO), the process of S135 is skipped and the process proceeds to S140.

  In the process of S140, an incoming message transmitted from another telephone as a communication destination is recorded (S140). The reception date and time recorded in the process of S125, the transmission source information recorded in the process of S135, and the incoming message recorded in the process of S140 are stored in the storage unit 22 as one message ( S145), the incoming call process shown in FIG.

  In the case of an analog telephone, the message stored in the storage unit 22 by the process of S145 stores voice data encoded by the ADPCM method or the like in the MFC1. In the case of an IP phone, voice data encoded by the μ-Law system or A-Law system is transmitted from another telephone as a communication destination, so that the voice data is stored as it is. .

  Further, the message stored in the storage unit 22 by the process of S145 is saved as a file in the “answering machine data folder” provided in the storage unit 22 of the MFP 1. More specifically, the storage unit 22 of the MFP 1 is provided with a group of folders such as “Audio folder”, “Image folder”, and “Video folder” as shown in FIG. In the “Audio folder”, a “MUSIC data folder”, an “answering machine data folder”, and the like are provided. In this “answering machine data folder”, “character string“ TEL ”+ sequential number.extension”. The message stored in the process of S145 is saved with the file name of the format. In the case of the file illustrated in FIG. 4, the extension is “ADPCM”, and it is possible to identify the voice data encoded by the ADPCM method from this extension. The “MUSIC data folder”, “Image folder”, and “Video folder” store music files in MP3 format, still image files in JPEG format, moving image files in MPEG format, and the like. These files are prepared for transmission to the player (the television 3 or the audio device 4) when the MFP 1 functions as a server.

[Voice Mail / Music Playback Processing]
Next, an answering machine / music reproduction process corresponding to the process of S25 will be described with reference to FIG.

FIG. 5 is a flowchart showing an answering machine / music reproduction process executed by the MFP 1.
When the answering machine / music playback process is started, the MFP 1 first determines whether it is answering machine data to be played back (S210). Since the user instructs whether to play the answering machine data or the music data by performing a predetermined operation on the panel unit 14, the MFP 1 reproduces based on the operation performed on the panel unit 14. It is determined whether it is answering machine data or music data.

  If it is determined in the processing of S210 that it is the answering machine data to be reproduced (S210: YES), the MFP 1 uses the built-in voice CODEC (FAX MODEM / voice CODEC 19) without converting the data format of the answering machine data. Then, the answering machine data is reproduced (S215). As a result, the user can listen to the voice recorded as answering machine data using the speaker provided in the handset 20 or the main body speaker 21.

  On the other hand, in the process of S210, when it is determined that it is not the answering machine data to be reproduced (S210: NO), the MFP 1 sets the data format of the music data to a DLNA (registered trademark) compatible format (in the case of this embodiment). MP3 format) is converted to a data format corresponding to the built-in audio CODEC, and the converted audio data is reproduced using the built-in audio CODEC (S220). As a result, the user can listen to music recorded as music data using the speaker or the main body speaker 21 provided in the handset 20.

When the process of S215 or S220 is thus completed, the answering machine / music playback process is terminated.
[File list transfer process]
Next, the file list transfer process corresponding to the process of S35 will be described with reference to FIG.

FIG. 6 is a flowchart showing file list transfer processing executed by MFP 1.
When the file list transfer process is started, the MFP 1 keeps the file name as it is for the data in the DLNA (registered trademark) compatible format, and for the answering machine data, the extension in the file name is the extension in the DLNA (registered trademark) compatible format. (In this embodiment, “MP3” is substituted), and the data list is transmitted to the DLNA (registered trademark) device (S310).

  The data list transmitted by the process of S310 is a data list as shown in FIG. Specifically, files with extensions “MP3”, “JPEG”, and “MPEG” correspond to data in a format compatible with DLNA (registered trademark). And On the other hand, for the answering machine data file with the extension “ADPCM”, the extension in the file name is replaced from “ADPCM” to “MP3”. These file name lists are transmitted to the DLNA (registered trademark) device as the transmission destination.

  Here, if the transmission destination is the television 3, a data list as shown in FIG. 7 is displayed on the screen of the television 3. The television 3 recognizes that data in a DLNA (registered trademark) compatible format is a reproducible content, and in the example shown in FIG. 7, the extensions are “MP3”, “JPEG”, “MPEG”. "Is recognized as reproducible content. On the other hand, the television 3 does not normally recognize that the data in ADPCM format is a reproducible content, and therefore does not recognize the file having the extension “ADPCM” as a reproducible content. .

  However, in the process of S310, since the data list in which the extension is replaced with “MP3” is transmitted for the file with the extension “ADPCM”, the MP3 that can be played back on the TV 3 is transmitted on the TV 3 side. Recognize that there is a form of answering machine data. That is, at the time when the process of S310 is executed, although only the answering machine data in ADPCM format exists on the MFP 1 side, the TV 3 indicates that the answering machine data in MP3 format exists on the MFP 1 side as a data list. Will be notified.

When the process of S310 as described above is completed, the file list transfer process is terminated.
[File transmission processing]
Next, the file transmission process corresponding to the process of S45 will be described with reference to FIG.

FIG. 8 is a flowchart showing file transmission processing executed by the MFP 1.
When the file transmission process is started, the MFP 1 first determines whether it is answering machine data to be transmitted (S410). Whether or not the answering machine data should be transmitted can be determined based on the file transmission request transmitted from the television 3 or the audio device 4 that is the request source.

  For example, after a data list as shown in FIG. 7 is displayed on the television 3, when a user selects one content in the data list by performing a predetermined operation on the television 3 side, the content of the content is displayed. A file transmission request for requesting transmission is transmitted from the television 3 side to the MFP 1 side. Since the file transmission request includes the name of the file requesting transmission, the MFP 1 can determine whether it is answering machine data to be transmitted based on the file name. . Since the content in the data list is selected on the television 3 side, the file name of the answering machine data selected on the television 3 side is the file name with the extension replaced with MP3.

  In the process of S410, when it is determined that it is the answering machine data to be transmitted (S410: YES), the MFP 1 converts the answering machine data stored in the ADPCM format into a DLNA (registered trademark) compatible format (in the present embodiment). In this case, the data is converted into MP3), and the converted data is transmitted to the DLNA (registered trademark) device (S415).

  On the other hand, if it is determined in the processing of S410 that it is not the answering machine data to be transmitted (S410: NO), the MFP 1 uses a DLNA (registered trademark) compatible format (in this embodiment, the extension is “MP3”). , “JPEG” or “MPEG”) is transmitted, the data format is not converted and is directly transmitted to the DLNA (registered trademark) device (S420).

When the process of S415 or S420 is thus completed, the file transmission process is terminated.
[Effect of the first embodiment]
As described above, according to the MFP 1, the incoming message transmitted from the IP telephone 8 or the analog telephone 9 is processed by the processing in S 145 and is compatible with the built-in voice CODEC that cannot be reproduced by the television 3 or the audio device 4 ( It is stored in the storage unit 22 as audio data in the ADPCM format, μ-Law format, or A-Law format (corresponding to the first format in the present invention). However, in the process of S415, the audio data in the internal audio CODEC compatible format is converted into audio data in a DLNA (registered trademark) compatible format (MP3 format; equivalent to the second format in the present invention), and DLNA (registered trademark) is converted. ) Audio data in a compatible format is transmitted to the television 3 and the audio device 4. Therefore, unlike the case where the audio data in the built-in audio CODEC compatible format is transmitted to the television 3 or the audio device 4 as it is, the TV 3 or audio device 4 can reproduce the audio data in the DLNA (registered trademark) compatible format. Thus, the incoming message recorded in the MFP 1 can be reproduced on the television 3 or the audio device 4.

  In the first embodiment, the MFP 1 converts the audio data in the built-in audio CODEC compatible format into the audio data in the DLNA (registered trademark) compatible format after executing the processing in S415 through the processing in S40 and S410. Therefore, although it is not certain whether an audio transmission request is transmitted from the television 3 or the audio device 4, there is no case where the conversion process is performed in advance. Therefore, the conversion only needs to be performed when there is a request from the television 3 or the audio device 4, and it is unnecessary to perform the conversion when there is no request from the television 3 or the audio device 4, which is useless. The conversion work need not be performed, and the load on the MFP 1 is reduced correspondingly, so that resources necessary for the conversion are not wasted.

  In the first embodiment, the MFP 1 uses DLNA (registered trademark) to store information related to the answering machine data stored in the storage unit 22 (information related to voice data in the first format referred to in the present invention) in S310. ) A data list (transmission candidate information referred to in the present invention) converted into information related to audio data in a compatible format is generated, and the generated data list is transmitted to the television 3 and the audio device 4. Therefore, the television 3 or the audio device 4 can recognize that the audio data can be reproduced by the television 3 or the audio device 4.

In addition, the television 3 and the audio device 4 can transmit a voice transmission request to the MFP 1 based on the data list, and the MFP 1 performs the process of S415 on the condition that the voice transmission request has been transmitted. Since the audio data is converted into a DLNA (registered trademark) compatible format, the conversion may be performed only when there is a request from the television 3 or the audio device 4, and there is no request from the television 3 or the audio device 4. There is no need to convert to.
(2) Second Embodiment Next, a second embodiment will be described. Although the second embodiment differs from the first embodiment in the content of processing executed in the MFP 1, the hardware configuration and the network configuration are the same as in the first embodiment. Differences from the first embodiment will be described in detail, and descriptions of configurations that are not different from the first embodiment will be omitted.

[Incoming call processing]
The telephone incoming call process described below is a process corresponding to the process of S15 described in the first embodiment, and is a process adopted instead of the telephone incoming call process shown in FIG.

FIG. 9 is a flowchart showing an incoming call process executed by the MFP 1 in the second embodiment.
Of the processes described below, the processes of S510 to S545 are the same as S110 to S145, and will be described briefly.

  That is, when the incoming call process is started, the MFP 1 first determines whether or not the user answers the telephone (S510). If it is determined in the process of S510 that the call is answered (S510: YES), the MFP 1 executes a process for making a normal call (S515), and ends the incoming call process shown in FIG.

  On the other hand, if it is determined in step S510 that the call is not answered (S510: NO), the MFP 1 reproduces a response message (S520). Then, the reception date and time is recorded (S525), it is determined whether or not there is a destination telephone number (S530). If there is a destination telephone number (S530: YES), the sender information is recorded (S535). , The process proceeds to S540. If there is no destination telephone number in the process of S530 (S530: NO), the process of S535 is skipped and the process proceeds to S540.

  In the process of S540, an incoming message transmitted from another telephone as a communication destination is recorded (S540). The reception date and time recorded in the process of S525, the transmission source information recorded in the process of S535, and the incoming message recorded in the process of S540 are stored in the storage unit 22 as one message (S545). ).

  When the processing of S545 is completed in this way, the reception date and time recorded in the processing of S525, the transmission source information recorded in the processing of S535, and the incoming message recorded in the processing of S540 are further DLNA (registered trademark) compatible. The data is converted into a format and stored in the storage unit 22 (S550). The process of S550 is a process that is not executed in the first embodiment, and corresponds to a portion that is different from the first embodiment.

  Further, the message stored in the storage unit 22 by the processing of S545 is saved as a file in the “answering machine data folder” provided in the storage unit 22 of the MFP 1 as described in the first embodiment. The message stored in the storage unit 22 by the processing of S550 is also saved as a file in the “answering machine data folder” provided in the storage unit 22 of the MFP 1.

  More specifically, as illustrated in FIG. 10, the storage unit 22 of the MFP 1 is provided with a folder group such as “Audio folder”, “Image folder”, and “Video folder” as already described in the first embodiment. In the “Audio folder”, a “Voice mail data folder” and the like are provided.

  Then, in this “answering machine data folder”, the message stored in the process of S545 and S550 with the file name of the form “character string“ TEL ”+ serial number.extension” is stored, but the process of S545 The message saved with the extension is “ADPCM”, and the message saved in the process of S550 has the extension “MP3”.

In other words, incoming messages having the same contents are stored twice in the ADPCM format and the MP3 format in the “Voice Mail Data Folder”.
[Voice Mail / Music Playback Processing]
Next, an answering machine / music reproduction process corresponding to the process of S25 described in the first embodiment will be described with reference to FIG.

FIG. 11 is a flowchart showing an answering machine / music playback process executed by the MFP 1 in the second embodiment.
When the answering machine / music playback process is started, the MFP 1 first determines whether it is answering machine data to be played back (S610). The process of S610 is equivalent to the process of S210.

  In the processing of S610, when it is determined that it is the answering machine data to be reproduced (S610: YES), the MFP 1 uses the built-in voice CODEC (FAX MODEM / voice CODEC19) of the answering machine data stored in two types of formats. ) Is selected, and the selected answering machine data is reproduced using the built-in voice CODEC (S615). As a result, the user can listen to the voice recorded as answering machine data using the speaker provided in the handset 20 or the main body speaker 21.

  On the other hand, if it is determined in the processing of S610 that it is not the answering machine data to be reproduced (S610: NO), the MFP 1 sets the data format of the music data to a DLNA (registered trademark) compatible format (in this embodiment). MP3 format) is converted to a data format corresponding to the built-in audio CODEC, and the converted audio data is reproduced using the built-in audio CODEC (S620). The process of S620 is equivalent to the process of S220.

When the processing of S615 or S620 is thus completed, the answering machine / music playback processing is terminated.
As described above, in the first embodiment, the answering machine data is stored in only one type, and thus the answering machine data is reproduced. In the second embodiment, the answering machine data is reproduced in two types. Since the answering machine data is stored, the answering machine data in a format corresponding to the built-in voice CODEC is selected, and the selected answering machine data is reproduced.

[File list transfer process]
Next, a file list transfer process corresponding to the process of S35 described in the first embodiment will be described with reference to FIG.

FIG. 12 is a flowchart showing a file list transfer process executed by the MFP 1 in the second embodiment.
When the file list transfer process is started, the MFP 1 keeps the file name as it is for the data in the DLNA (registered trademark) compatible format, and for the answering machine data, the DLNA (registered trademark) is stored in two types of data. ) Select only the file name having the extension of the corresponding format (in the present embodiment, “MP3”), and transmit the data list to the DLNA (registered trademark) device (S710).

  The data list transmitted by the processing of S710 is a data list as shown in FIG. Specifically, files with extensions “MP3”, “JPEG”, and “MPEG” correspond to data in a format compatible with DLNA (registered trademark), so in the processing of S710, the file name is left as it is. And On the other hand, as for the answering machine data, as shown in FIG. 10, although files with different extensions are stored twice, only the answering machine data file with the extension “MP3” is selected. . These file name lists are transmitted to the DLNA (registered trademark) device as the transmission destination.

  Therefore, for example, if the transmission destination is the television 3, a data list as shown in FIG. 7 is displayed on the screen of the television 3, and the following is performed on the television 3 side as in the first embodiment. The DLNA (registered trademark) compatible format data is recognized as reproducible content, and in the example shown in FIG. 7, the extensions are “MP3”, “JPEG”, and “MPEG”. It is recognized that the file is a reproducible content.

When the process of S710 as described above is completed, the file list transfer process is terminated.
[File transmission processing]
Next, a file transmission process corresponding to the process of S45 described in the first embodiment will be described with reference to FIG.

FIG. 13 is a flowchart showing a file transmission process executed by the MFP 1 in the second embodiment.
When the file transmission process is started, the MFP 1 first determines whether it is answering machine data to be transmitted (S810). The process of S810 is equivalent to the process of S410.

  In the process of S810, when it is determined that it is the answering machine data to be transmitted (S810: YES), the MFP 1 supports DLNA (registered trademark) from the answering machine data stored in two types of data formats. Data of the format (MP3 in this embodiment) is selected, and the selected data is transmitted to the DLNA (registered trademark) device (S815).

  On the other hand, if it is determined in the processing of S810 that it is not the answering machine data to be transmitted (S810: NO), the MFP 1 uses a DLNA (registered trademark) compatible format (in this embodiment, the extension is “MP3”). , “JPEG” or “MPEG” file is transmitted, so the data format is not converted and is directly transmitted to the DLNA (registered trademark) device (S820).

When the process of S815 or S820 is thus completed, the file transmission process is terminated.
[Effects of Second Embodiment]
As described above, according to the MFP 1, the incoming message transmitted from the IP telephone 8 or the analog telephone 9 is processed in S545 so that it cannot be played back on the television 3 or the audio device 4 (a format compatible with the built-in voice CODEC ( It is stored in the storage unit 22 as audio data in the ADPCM format, μ-Law format, or A-Law format (corresponding to the first format in the present invention). However, by the process of S550, the DLNA (registered trademark) compatible format (MP3 format; equivalent to the second format in the present invention) is also stored in the storage unit 22 and the DLNA (registered trademark) compatible format audio data is stored. The data is transmitted to the television 3 and the audio device 4 by the process of S815. Therefore, unlike the case where the audio data in the built-in audio CODEC compatible format is transmitted to the television 3 or the audio device 4 as it is, the TV 3 or audio device 4 can reproduce the audio data in the DLNA (registered trademark) compatible format. Thus, the incoming message recorded in the MFP 1 can be reproduced on the television 3 or the audio device 4.

In the second embodiment, the MFP 1 converts the incoming message as DLNA (registered trademark) -compatible audio data through the processing of S550 regardless of whether there is a transmission request from the television 3 or the audio device 4. Since it is stored in the storage unit 22, DLNA (registered trademark) -compatible audio data is immediately transmitted to the television 3 and the audio device 4 even if conversion is not started when a transmission request is received from the television 3 or the audio device 4. can do.
(3) Third Embodiment Next, a third embodiment will be described. In the third embodiment, the contents of the processing executed in the MFP 1 are different from those in the first embodiment and the second embodiment, but the hardware configuration and the network configuration are the same as those in the first embodiment. In the description, differences from the first embodiment and the second embodiment will be described in detail, and descriptions of configurations that are not different from the first embodiment and the second embodiment are omitted.

[Outline of processing executed by MFP]
First, an outline of processing executed by the MFP 1 in the third embodiment will be described with reference to FIG. The process shown in FIG. 14 is a process employed instead of the process shown in FIG. 2 in the first embodiment.

Of the processes described below, the processes of S910 to S945 are equivalent to S10 to S45, and will be described briefly.
When this process is started, the MFP 1 first determines whether there is an incoming call (S910). Here, if there is an incoming call from another telephone, it is determined that there is an incoming telephone call (S910: YES), and in this case, a telephone incoming call process is executed (S915). When the incoming call process is completed, the process returns to S910, and the processes after S910 are repeated.

  If it is determined in S910 that there is no incoming call (S910: NO), the MFP 1 determines whether there is an answering machine / music playback instruction (S920). Here, if the user has instructed playback of an incoming message recorded by the answering machine function of the MFP 1 or playback of music stored in the storage unit 22 of the MFP 1 by an operation on the panel unit 14, It is determined that there is an answering machine / music reproduction instruction (S920: YES). In this case, an answering machine / music reproduction process is executed (S925). When the answering machine / music reproduction process is completed, the process returns to S910, and the processes after S910 are repeated.

  If it is determined in the process of S920 that there is no answering machine / music playback instruction (S920: NO), the MFP 1 determines whether there is a file list transfer request (S930). Here, if a file list transfer request is transmitted from the TV 3 or the audio device 4 to the MFP 1 by performing a predetermined operation on the TV 3 or the audio device 4, it is determined that there is a file list transfer request. (S930: YES), in this case, a file list transfer process is executed (S935). When the file list transfer process ends, the process returns to S910, and the processes after S910 are repeated again.

  If it is determined in step S930 that there is no file list transfer request (S930: NO), the MFP 1 determines whether there is a file transmission request (S940). Here, if a user performs a predetermined operation on the television 3 or the audio device 4 and a file transmission request is transmitted from the television 3 or the audio device 4 to the MFP 1, it is determined that there is a file transmission request. (S940: YES), in that case, a file transmission process is executed (S945). When the file transmission process ends, the process returns to S910, and the processes after S910 are repeated again.

  In the process of S940, when it is determined that there is no file transmission request (S940: NO), the MFP 1 determines whether a new DLNA (registered trademark) device is connected to the LAN 5 (S950). Here, the fact that the television 3 and the audio device 4 that have been disconnected from the LAN 5 are newly connected to the LAN 5 can be detected by a Discovery command of UPnP (registered trademark). If this state change is detected, it is determined in step S950 that the DLNA (registered trademark) device is connected to the LAN 5 (S950: YES). In this case, the DLNA (registered trademark) device connection processing is executed. (S955). Details of the DLNA (registered trademark) device connection process will be described later. When the DLNA (registered trademark) device connection process is completed, the process returns to S910, and the processes after S910 are repeated.

  If it is determined in step S950 that a new DLNA (registered trademark) device is not connected to the LAN 5 (S950: NO), the MFP 1 detects that the DLNA (registered trademark) device is disconnected from the LAN 5. It is determined whether or not (S960). Here, the disconnection of the television 3 and the audio device 4 from the LAN 5 can be detected by a Discovery command of UPnP (registered trademark). If this state change is detected, in the process of S960, it is determined that the DLNA (registered trademark) device is disconnected from the LAN 5 (S960: YES). In this case, the DLNA (registered trademark) device disconnection process is executed. (S965). Details of the DLNA (registered trademark) device disconnection process will be described later. When the DLNA (registered trademark) device disconnection process is completed, the process returns to the process of S910, and the processes after S910 are repeated again.

  Further, in the process of S960, when it is determined that the DLNA (registered trademark) device is not disconnected from the LAN 5 (S960: NO), the MFP 1 executes other processes (S970). The process in S970 is equivalent to the process in S50. When the process of S970 is completed, the process returns to the process of S910, and the processes after S910 are repeated again.

  Note that the processing described above is a flowchart in which determination processing such as S910, S920, S930, S940, S950, and S960 is periodically repeated for the sake of illustration, but like the processing illustrated in FIG. An equivalent process may be realized by other methods. For example, when an event occurs in which an affirmative determination is made in each process of S910, S920, S930, S940, S950, and S960, as an interrupt process corresponding to the event, S915, S925, S935, S945, S955 Even if the configuration is such that each process of S965 is executed, a process equivalent to the process shown in FIG. 14 can be realized.

[DLNA (registered trademark) equipment connection processing]
Next, DLNA (registered trademark) device connection processing corresponding to the processing of S955 will be described with reference to FIG.

FIG. 15 is a flowchart showing a DLNA (registered trademark) device connection process executed by the MFP 1.
When this process is started, the MFP 1 converts the answering machine data already stored in a format compatible with the built-in voice CODEC into a format compatible with DLNA (registered trademark), and stores the answering machine data in both formats in duplicate. (S1010).

  The data of the answering machine that will be received in the future is also stored twice (S1020). More specifically, in the third embodiment, the MFP 1 is configured to store the answering machine data only in a format compatible with the built-in voice CODEC until the stage before executing the processing of S1020, as in the first embodiment. ing. On the other hand, after executing the processing of S1020, as in the second embodiment, it is possible to switch to a setting in which the answering machine data is stored twice in both the built-in voice CODEC compatible format and the DLNA (registered trademark) compatible format. . As a result, when the process of S1020 is executed, the received answering machine data is stored twice.

When the process of S1020 is completed, the DLNA (registered trademark) device connection process shown in FIG. 15 is terminated.
[Process when disconnecting DLNA (registered trademark) equipment]
Next, a DLNA (registered trademark) device disconnection process corresponding to the process of S965 will be described with reference to FIG.

FIG. 16 is a flowchart showing a DLNA (registered trademark) device disconnection process executed by the MFP 1.
When this process is started, the MFP 1 first determines whether or not all DLNA (registered trademark) devices are confirmed to be connected to the LAN 5 by a UPnP (registered trademark) Discovery command (S1110). In the processing of S1110, a negative determination is made if there is even one DLNA (registered trademark) device connected to the LAN 5, and affirmation is made only when there is no DLNA (registered trademark) device connected to the LAN 5. Judgment is made.

  If it is determined in step S110 that it is confirmed that all DLNA (registered trademark) devices are not connected to the LAN 5 (S1110: YES), the MFP 1 is already compatible with the built-in voice CODEC compatible format and DLNA (registered trademark). Only the data in the DLNA (registered trademark) compatible format is deleted from the answering machine data stored twice in the format (S1115).

  Also, only one type of built-in voice CODEC compatible format is stored in the answering machine data received in the future (S1120). More specifically, in the third embodiment, when the MFP 1 executes the above-described processing of S1020, as in the second embodiment, the voice mail data is converted into the built-in voice CODEC compatible format and the DLNA (registered trademark) compatible format. However, after the processing of S1120 is executed, it can be switched to the setting for storing the answering machine data only in the built-in voice CODEC compatible format, as in the first embodiment. . As a result, when the processing of S1120 is executed, the received answering machine data is stored only in the built-in voice CODEC compatible format.

  When the process of S1120 is completed, the DLNA (registered trademark) device disconnection process illustrated in FIG. 16 is terminated. If one or more DLNA (registered trademark) devices are connected to the LAN 5 in the process of S110 (S1110: NO), the DLNA (registration) shown in FIG. 16 is not executed without executing the processes of S1115 and S1120. (Trademark) End processing when the device is disconnected.

[Supplemental explanation]
As described above, in the third embodiment, when even one DLNA (registered trademark) device is connected to the LAN 5, the answering machine data is stored in the built-in voice CODEC compatible format and the DLNA (registered trademark) on the condition. ) It is in a state of being stored twice in both supported formats. Also, when there is no DLNA (registered trademark) device connected to the LAN 5, the answering machine data is stored only in the built-in voice CODEC compatible format on the condition.

  Therefore, when the answering machine data is stored in both the built-in voice CODEC compatible format and the DLNA (registered trademark) compatible format, the processing in S915 and S925 is the same as that in the second embodiment. Is executed. On the other hand, when the answering machine data is stored only in the built-in voice CODEC compatible format, the processes in S915 and S925 are the same as those in the first embodiment. When the processes of S935 and S945 are executed, one or more DLNA (registered trademark) devices are always connected to the LAN 5, and therefore, the same process as in the second embodiment is executed. become.

[Effect of the third embodiment]
As described above, according to the MFP 1, when at least one DLNA (registered trademark) device is connected to the LAN 5, the data of the answering machine is converted into the built-in voice CODEC compatible format and DLNA (registered) by the processing of S950 and S955. In this case, the same operation and effect as the MFP 1 of the second embodiment are exhibited.

  In addition, unlike the second embodiment, in the third embodiment, when no DLNA (registered trademark) device is connected to the LAN 5, the data of the answering machine is built in by the processing of S960 and S965. The state is stored only in the audio CODEC compatible format.

  Therefore, the conversion only needs to be performed when the television 3 or the audio device 4 is connected to the LAN 5, and it is unnecessary to perform the conversion when the television 3 or the audio device 4 is not connected to the LAN 5. Therefore, the load applied to the MFP 1 is reduced, and resources necessary for the conversion are not wasted.

In addition, when the television 3 or the audio device 4 is disconnected from the LAN 5, the audio data in the DLNA (registered trademark) compatible format is deleted from the storage unit 22, so whether the television 3 or the audio device 4 is reconnected to the LAN 5. Even if it is not certain, the audio data in the DLNA (registered trademark) compatible format will not be left in the storage unit 22 in vain.
(4) Fourth Embodiment Next, a fourth embodiment will be described. The fourth embodiment is different from the first to third embodiments in the content of processing executed in the MFP 1, but the hardware configuration and the network configuration are the same as those in the first embodiment. Now, differences from the first to third embodiments will be described in detail, and descriptions of configurations that are not different from the first to third embodiments are omitted.

  In the fourth embodiment, the “file list transfer process” corresponding to the process of S35 described in the first embodiment or the process of S935 described in the third embodiment, and the process of S45 described in the first embodiment or the The “file transmission process” corresponding to the process of S945 described in the third embodiment is a process different from the other examples. Processes other than “file list transfer process” and “file transmission process” may be the same as those in any of the first to third embodiments.

[File list transfer process]
FIG. 17 is a flowchart illustrating file list transfer processing executed by the MFP 1 in the fourth embodiment.

  When this file list transfer process is started, the MFP 1 keeps the file name as it is for DLNA (registered trademark) compatible format data, and the answering machine data as a single file name even if there are multiple files. Is transmitted to the DLNA (registered trademark) device (S1210).

  In the process of S1210, when the same configuration as that of the first embodiment is adopted, even if there is actually only a file in the built-in voice CODEC compatible format for the answering machine data, A file name in a DLNA (registered trademark) compatible format is transmitted. When the same configuration as that of the second embodiment or the third embodiment is adopted, the answering machine data is duplicated with a built-in voice CODEC compatible file and a DLNA (registered trademark) compatible file. Therefore, the file name of the DLNA (registered trademark) compatible format is transmitted. However, in any case, even if there are a plurality of files, one file name is used.

  Therefore, the television 3 recognizes that there is only one file for the answering machine data. When the process of S1210 as described above is completed, the file list transfer process is terminated.

[File transmission processing]
FIG. 18 is a flowchart illustrating file transmission processing executed by the MFP 1 in the fourth embodiment.

  When the file transmission process is started, the MFP 1 first determines whether it is answering machine data to be transmitted (S1310). The process of 1310 is equivalent to the process of S410 or S810.

  In the process of S1310, when it is determined that it is the answering machine data to be transmitted (S1310: YES), the MFP 1 records all the recordings regardless of whether there is one or more stored answering machine data. The messages are combined into a single file, and the single file is transmitted to the DLNA (registered trademark) device (S1315).

  In the process of S1315, when the same configuration as that of the first embodiment is adopted, a file in a format compatible with the built-in audio CODEC is converted into a file in a format compatible with DLNA (registered trademark), and then a plurality of files are combined. Or after synthesizing a plurality of files, the synthesized internal audio CODEC compatible format file is converted into a DLNA (registered trademark) compatible format file. Further, when the same configuration as that of the second embodiment or the third embodiment is adopted, the file having the built-in audio CODEC compatible format and the file corresponding to the DLNA (registered trademark) format are duplicated. A plurality of files are synthesized for a file in a registered trademark compatible format. In either case, the combined single file is transmitted to the DLNA (registered trademark) device.

  On the other hand, if it is determined in the processing of S1310 that it is not the answering machine data to be transmitted (S1310: NO), the MFP 1 uses a DLNA (registered trademark) compatible format (in this embodiment, the extension is “MP3”). , “JPEG” or “MPEG”) is transmitted, and the plurality of files are transmitted as they are to the DLNA (registered trademark) device without being combined (S1320).

When the process of S815 or S820 is thus completed, the file transmission process is terminated.
[Effect of Fourth Embodiment]
The MFP 1 of the fourth embodiment described above also has the same operations and effects as any of the MFPs 1 shown in the first to third embodiments.

Also, in the case of the fourth embodiment, unlike the other embodiments, a plurality of answering machine data is synthesized into one synthesized voice data, and then one synthesized voice data is transmitted to the DLNA (registered trademark) device. When playing back the answering machine data on the DLNA (registered trademark) device side, it is easy to specify one synthesized voice data without having to specify each of the answering machine data one by one. Answering machine data can be played back.
(5) Modifications The embodiment of the present invention has been described above. However, the present invention is not limited to the specific embodiment described above, and can be implemented in various other forms.

For example, in the above-described embodiment, the MFP 1 is illustrated as the communication apparatus of the present invention, but whether or not the scanner apparatus, the printer function, the copy function, the facsimile function, and the like are provided is arbitrary.
In the above embodiment, the MFP 1 has both a server function and a player function compliant with the DLNA (registered trademark) guidelines. However, whether the MFP 1 has a player function is arbitrary.

  In the above embodiment, the MFP 1, the television 3, and the audio device 4 perform data transmission / reception in the communication method conforming to the DLNA (registered trademark) guidelines. If it can be realized, it is optional whether the communication method itself is a communication method compliant with the DLNA (registered trademark) guidelines.

  Further, in the above-described “phone call processing” of each embodiment, it has been described that the response message reproduction, reception date and time recording, transmission source information recording, and incoming message recording are performed in this order. For example, the reception date and time and sender information may be recorded in parallel with the response message playback, or the reception date and time and sender information may be recorded after the incoming message is recorded. Can be changed.

  Although not mentioned in the above embodiments, recording of the reception date and time, recording of sender information, and recording of incoming messages are performed in this order, and a single file in which all of these are recorded is generated. Alternatively, it may be carried out in an appropriate order to generate a plurality of temporary files each recorded, and then combine the plurality of temporary files to complete one file.

  Further, in each of the above embodiments, the MP3 format audio data is exemplified as the DLNA (registered trademark) compatible format audio data. However, if the audio data conforms to the DLNA (registered trademark) guidelines, other than MP3 format audio data is exemplified. It may be in a data format.
