May be.

Next, a flow when music is played back by the mobile phone 1 in the embodiment of the present invention will be described with reference to FIGS. The operation of the mobile phone 1 according to the present invention is divided as follows.
(1) Operation when an incoming call is received during music playback with BT-AV connection (FIG. 7)
(2-1) MP start operation (FIG. 8)
(2-2) BT-AV connection (connection between mobile phone 1 and BT-equipped communication device, the same applies hereinafter) start operation (FIG. 10)
(2-3) MP operation / speaker / earphone output (hereinafter referred to as SP / EP output) (FIG. 9)
(2-4) MP operation / BT-AV connected device output (FIG. 11)
Hereinafter, each operation will be described separately. This will be described with reference to FIGS. 12 and 13 as appropriate. FIG. 12 is a diagram for explaining the music information recorded in the music information storage unit 115a in the mobile phone 1, and FIG. 13 shows an example of the display screen of the display 5 when the mobile phone 1 is operating. It is a thing.

[(1) Operation when there is an incoming call when playing music with BT-AV connection]
An outline of the operation and an operation when there is an incoming call during BT-AV connection will be described. This is one of the important points of the present invention. FIG. 7 is a flowchart showing the operation when there is an incoming call during music playback with BT-AV connection. First, when the user performs a reproduction operation of music information stored in the music information storage unit 115a (step S101, details will be described later), the BT-AV connection procedure and the like (2-1) to (2-3) described later will be described. Is determined based on the sound output setting information storage unit 115c (step S102, details will be described later). When the sound output destination is SP / EP, output is made to the speaker 109 / earphone, respectively (“SP / EP” in step 102). In this case, if the incoming call is interrupted, the reproduction of the music is interrupted and a normal ring tone is output.

  On the other hand, when the sound output destination is BT (“BT” in step S102), the music information (first file format) is read from the music information storage unit 115a, and the music control unit 105 displays the information shown in FIG. Information (second file format) related to the sound information to be reproduced shown in FIG. 12B is extracted from the music information (first file format) shown. Information related to the sound information to be reproduced in the second file format is sent to the BT communication unit 118, and the BT communication unit 118, as shown in FIG. Information (header or the like) is added so as to conform to the third file format), and the antenna 119 is disassembled as the third file format and transmitted to the BT-AV device (for example, the BT headphones 200) by BT. On the BT-AV device side (BT headphone 200), the music control unit 202 can reproduce the transmitted file on the BT headphone 200 by decoding the transmitted file (step S103). In the mobile phone 1, the music information being played back is kept on the RAM according to the second file format until one (or a predetermined number) of the music to be played has been played, and the music has been played back. It is desirable to control to delete.

  Here, FIGS. 12A to 12C will be described. FIG. 12A is a diagram simply showing when the music information is in the first file format. In the music information, “sound information” related to the sound itself and “additional information” made up of image data and music information (song name, etc.) related to the sound are included in one file. Usually, this first file format is stored in the song information storage section of the storage section 115a. FIG. 12B is a diagram simply showing when the music information is in the second file format. This is composed of “sound information” in the first file format and a header / footer including information based thereon. FIG. 12C is a diagram simply showing when the music information is in the third file format. The third file format is a file format to which information necessary for making the information of the second file format suitable for BT communication is added.

  Next, it is determined whether or not the mobile phone 1 is interrupted during the music information reproduction in step S103 (step S104). If there is an interrupt incoming call (“Yes”), the music control unit 105 determines the transmitted position of the music information and stores it in the RAM 111 (step S105). Thereafter, the transmission of the music information currently being transmitted by the BT is stopped (step S106).

  Next, the ring tone information stored in the ring tone storage unit 115d in the storage unit 115 is read out, and the music control unit 105 converts the first format to the second file format in the same manner as the music information, and further the first 3 is transmitted to the BT-AV device and output to the BT-AV device (step S107). The ring tone information is preferably stored in advance as the first format in the ring tone storage unit 115d, but is stored in advance in the form of the second file format, the third file format, and information corresponding thereto. You may keep it. Also, the ring tone information has only ring tone information for a short period of time and is prepared for a time that can be notified to the user (for example, about 500 MS). It is desirable that the ring tone has information different from the normal ring tone information, and there may be one type, or multiple types so that the ring tone can be grouped or individually set in the phone book. But you can.

  Then, the control unit 101 stops the MP function (step 108) and causes a normal ringing tone to sound from the speaker 109 on the mobile phone 1 side (step S109). In that case, ring the ring tone set individually (set in the phone book (not shown)) as usual, ring the ring tone for each group, or set the vibration setting individually set in manner mode Or vibrate according to the vibration setting for each group.

  Thereafter, it is determined whether or not a call operation is performed by pressing the call key 70 (step S110). When a call operation is performed by pressing the call key 70 or the like, the call is started (step 110 "Yes"). . Thereafter, it is determined whether or not the call has ended (step S111). When the end operation is performed, for example, by pressing the end key 71, the end of the call is made (step S111 "Yes"). Thereafter, the MP function is activated again, and an MP activation operation described later is performed (step S112). In that case, the transmitted position information of the music information stored in the RAM 111 in step S105 is read (step S113), and the music control unit 105 plays back from the middle of the music based on the transmitted position of the music information stored in the RAM 111. (Step S114). For example, a music piece several seconds before the music information transmission position may be output again to the speaker 109 or the speaker 205 on the BT-AV device side, or may be resumed from the music information transmission position. Also, the music information may be restarted from the beginning of the music being played back, or the music information is not played back immediately, and the playback key 211 of the BT headphones 200, the key 6 of the mobile phone, or the electrostatic touch pad 14 is pressed. Then, it may be held in the RAM 111 by the second file format so that the reproduced music can be reproduced immediately from the beginning.

  Note that the MP stop / MP start described in step S108 and step S112 can be stopped (suspended) / restarted in the background of incoming / call operation without stopping / starting the program itself. It is.

[(2-1) MP start operation]
Next, the MP start operation will be described. FIG. 8 is a flowchart showing the operation when the MP is activated. First, it is determined whether the Music Player (MP) is activated from the normal standby state of the mobile phone 1 (step S11). As MP activation methods, a call from a menu by pressing the enter key 65 (MP activation without reproduction), a call by pressing the side key 7 for a predetermined time (MP activation with reproduction), an electrostatic touchpad 14 for a predetermined time pressed (MP activation with reproduction). For example, a start with playback is a start that plays at the same time as the start, and a start without playback means a case where playback is not performed at the same time as the start. Including).

  Then, when the MP is activated (step S11 “Yes”), it is determined whether music is being played on the BGM (step S12), and if it is determined that music is being played on the BGM (“Yes”). ) Determines whether the BT-AV connection is established by the BT (step S13). If it is determined in step S12 that BGM playback is not in progress ("No"), it is determined whether BT-AV standby is in progress (step S14).

  Next, when it is determined in step S13 that the BT-AV connection is being made (“Yes”), the reproduction of the BGM music information has simply shifted to the reproduction on the MP, that is, the foreground (hereinafter referred to as FGM). Even in the middle of the music, the music continues to flow from the BT-AV device that is output as it is (“Yes” direction in step S13, <1> transition to step S60-2 in FIG. 11).

  On the other hand, if it is determined in step S13 that the BT-AV connection is not established ("No"), the music information is reproduced by the player operation of SP / EP output setting. Also in this case, the BGM playback at the output of SP / EP is simply shifted to FGM playback, and sound is output without interruption from the speaker or earphone that is output as it is even in the middle of the song ( “No” direction in step S13, <2> go to step S31-2 in FIG. 9).

If it is determined in step S14 whether or not BT-AV standby is in progress, it is determined that BT-AV standby is in progress (step S14 "Yes"). The server continues to wait for connection (<6>, step S50 in FIG. 10).
On the other hand, if it is determined in step S14 that BT-AV standby is in progress and it is determined that BT-AV standby is not in progress ("No"), whether or not BT-AV connection is in progress. Judgment is made (step S15).

  When it is determined that the BT-AV connection is being made (step S15 “Yes”), the player action is performed on the output destination during the BT-AV connection (<3>, step S60 in FIG. 11). Note that when performing this player action, for example, if the MP is activated with reproduction when the MP is activated in step S11, the player action (reproduction) is performed (step S60-2), and the MP without reproduction is performed. If it is activated, a player action (pause) is performed (step S60-3). This transition is an example, and it may be set to transition to any state (reproduction / stop / pause) in the frame of step S60 shown in FIG.

  On the other hand, if it is determined in step S15 that the BT-AV connection is not established (step S15 “No”), the sound output destination setting stored in the sound output setting information storage unit 15c is read out and the BT-AV connection is possible. It is determined whether or not the device is set to the correct device (step S16).

  If it is determined in step S16 that the sound output destination setting stored in the sound output setting information storage unit 15c is not a device capable of BT-AV connection ("No"), the player is connected by SP / EP. The operation is performed (<5>, proceed to S31 in FIG. 9). When performing this player action, for example, when MP is activated in step S11 and MP activation is accompanied by reproduction, player action (reproduction) is performed (step S31-2), and MP without reproduction is performed. If it is activated, a player action (pause) is performed (step S31-3). This transition is an example, and it may be set to transition to any state (reproduction / stop / pause) in the frame of step S31 shown in FIG.

  On the other hand, in step S16, when the sound output destination setting stored in the sound output setting information storage unit 15c is set to a device that can be connected to BT-AV (step S16 "Yes"), the set BT -Start BT-AV connection as a client to a device capable of AV connection (<4>, proceed to step S41 in FIG. 10). In this case, since the sound output destination setting when the player was last activated is stored in the sound output setting information storage unit 115C, the setting is used as it is. Therefore, it is possible to save the trouble of setting each time the player is activated.

  Note that the MP start operation is not limited to the activation according to the flow described in the flowchart of FIG. In other words, for example, when MP is activated in step S11, if the BGM is being played back and the BT-AV is connected, it may be designed to make a transition to <1> (FIG. 11). Similarly, for example, when MP is activated in step S11, BGM playback is not being performed, BT-AV standby is not being performed, BT-AV is not being connected, and the setting of the sound output setting information storage unit 115c is BT -If the device is set to be capable of AV connection, it may be designed to make a transition to <4> (FIG. 10).

[(2-2) BT-AV connection start operation]
Next, the BT-AV connection start operation will be described with reference to FIG. FIG. 10 is a flowchart when the BT-AV connection start operation is started. The BT-AV connection start operation is as follows: (A) When MP is activated (step S11), BGM playback is not being performed, BT-AV standby is not being performed, BT-AV connection is not being performed, and sound output setting information When the setting of the storage unit 115c is set to a device capable of BT-AV connection (transition from <4> in FIG. 8), and (B) the sound output destination setting is changed while the MP is activated by SP / EP connection. And when the change is made to a device capable of BT-AV connection (transition from <7> in FIG. 9).

  First, when the BT-AV connection start operation is performed as described above, a client is connected to a BT-AV connectable device set as a sound output destination (hereinafter, described as being set in the BT headphones 200). BT-AV connection operation (for example, connection by AV profile) is started (step S41). Thereafter, it is determined whether or not a connection cancel operation has been performed by the clear key 72 or the power key 71 (step S42). At that time, if a connection cancel operation is performed (“Yes”), the connection with the BT headphones 200 is ended (step S43). Then, the sound output setting is set as SP / EP connection (transition to <8> in FIG. 9).

  On the other hand, when the connection cancellation operation is not detected, it is determined whether or not the BT-AV connection is established by the client operation (step S44).

  When the BT-AV connection is established, the setting is rewritten to the BT-AV device (in this case, the BT headphones 200) to which the sound output destination information stored in the sound output setting information storage unit 115c can be connected (step S45). ). Thereafter, the player operation (stop) is performed by BT-AV connection (<9> transition to step S60-1 in FIG. 11).

  On the other hand, if it is not determined that the BT-AV connection has been established (“No” in step S44), it is determined whether or not a predetermined time has elapsed (timed out) from the time when the connection was started as a client, and a timeout occurs. If not, the process returns to step S42 again ("No" in step S46). If the time-out time is too short, it leads to a decrease in the connection rate. Conversely, if it is too long, the connection waiting time is too long, which is not preferable for the user, and several seconds (about 5 seconds) are desirable.

  Then, in steps S44 and S46, if connection as a client could not be established by a predetermined time (time-out) (“Yes” in step S46), the operation of the BT-AV connection that attempted to connect as a client is terminated. (Step S47). Next, when a connection is attempted as a connection failure reason, it is determined whether or not the connection has failed due to an authentication failure (authentication between the mobile phone 1 and the BT-AV device using a PIN code) (step S48). This is because in the case of connection failure due to authentication failure, it is necessary to accept the PIN code again and perform authentication with the BT-AV device.

  If it is not a connection failure due to an authentication failure (“No” in step S48), it is determined whether or not the connected BT-AV device (BT headphones 200) itself is a device that can operate as a client ( Step S49). A method for determining whether the device can operate as the client will be described later.

  If it is determined that the BT-AV device that has attempted to connect is a device that can be a client (“No” in step S49), the server then waits for a BT-AV connection (step S50). Note that, as a BT-AV connectable device that waits for connection as a server at this time, only the BT-AV device (in this case, the BT headphones 200) that has been attempted to connect as a client may be set. You may make it wait for a connection with respect to all the BT-AV apparatuses (In this case not only BT headphones 200 but other apparatuses, such as BT component 300) memorize | stored in the list memory | storage part 115b.

  Next, when a BT-AV connection waiting operation is performed as a server in step S50, it is then determined whether or not a connection canceling operation has been performed with the clear key 72 or the power key 71 (step S51).

  Thereafter, when a connection cancel operation is performed (“Yes”), the connection with the BT headphones 200 is ended (step S52). Further, the sound output setting is set as SP / EP connection (transition to <8> in FIG. 9).

  On the other hand, when the connection cancellation operation is not detected, it is determined whether or not the BT-AV connection is established by the server operation (step S53).

  When the BT-AV connection is established, the setting is rewritten as the BT-AV device to which the sound output destination information stored in the sound output setting information storage unit 115c can be connected (step S54). Thereafter, the player operation (stop) is performed by BT-AV connection (<9> transition to step S60-1 in FIG. 11).

  On the other hand, if it is not determined that the BT-AV connection has been established (“No” in step S53), it is determined whether or not a predetermined time has passed (timed out) from the time when the connection was started as a client, and the time-out has occurred. If not, the process returns to step S51 again (“No” in step S55). As a timeout time when waiting for connection as a server, since it is necessary to wait for the user to turn on the power of the connection destination after displaying the guidance to the user in step S50, tens of seconds to 1 Minutes are desirable.

  If the server cannot be connected within a predetermined time (timeout time) in steps S53 and S55 (“Yes” in step S55), the server mode operation is terminated (step S56). Further, the sound output setting is set as SP / EP connection (<8> proceeds to step S35 in FIG. 9).

  If it is determined in step S48 that the failure reason is authentication failure (“Yes” in step S48), it is determined in step S49 that the BT-AV connectable device that has attempted connection cannot be a client ( In “No” in step S49), the control unit 101 sets the sound output setting as SP / EP connection (<8> transition to step S35 in FIG. 9).

  In step S48, if the reason for the connection failure is authentication failure (“Yes”), the process proceeds to <8> (FIG. 9) and the connection is not limited to the SP / EP connection. If the failure reason is authentication failure, the PIN code for authenticating the PIN code of the BT-AV device that has attempted the connection again is received, and then the process returns to step S41, and the BT-AV device returns the client to the client. It may be set to retry the connection.

  In this BT-AV connection operation, a connection is first performed as a client, and a server mode operation is performed when the connection fails. However, the same effect can be obtained by replacing this operation. Further, even when the mobile phone 1 and a BT-AV device capable of operating a client (for example, the BT headphones 200) perform the client connection operation at the same time, the communication connection can be established by repeating the operation of this embodiment. it can.

(Determining whether a device capable of BT-AV connection can be a client)
Next, a detailed description will be given of a method for determining whether or not the BT-AV device that has attempted connection in step S49 can become a client. The following four methods (A) to (D) are conceivable, and any of the methods and combinations thereof are realized.
(A) Estimating that you can become a client without making any particular judgment When transitioning to step S49, it is assumed that you can become a client without making any particular judgment, and the process always transitions to step S50.

(B) When registering the peripheral device list, information on whether or not to become a client is set at the same time. As described above, the peripheral device list is obtained by searching the BT before starting the MP, and the BT connection is established. Whether or not the device can be connected as a client to each BT-AV connectable device when the list is obtained (displayed) is required to be stored in the list storage unit 115b. Is stored in the BT connection list storage unit 115b in association with each piece of device information. When the process proceeds to step S49, the information is read to determine whether or not the client can be a client.

(C) Judgment from information loaded when searching the peripheral device list Searching the peripheral device list, the loaded information includes service information (for example, a service record stored in a location called “SDDB” in the BT standard) ) Is included, but based on the Supported Features information of the service information, it is determined whether or not the device can be a client. The Supported Features information includes information about which terminal the device is in, and according to the classification, information on this classification and whether to be a client in advance in the storage unit 115 of the mobile phone 1 It can be considered that information (not shown) is set in association with each other, and it is determined whether or not a connected BT-AV device can be a client based on the information. Specifically, for example, if a flag indicating Headset is set in the Supported Features information in advance, it is determined that the BT-AV device can be a client and a server, and if any other flag is set, it can only be a server. It is stored in the storage unit 115 in association with each piece of information so that it is determined that there is no BT-AV device. At the time of the determination in step S49, the device that has attempted connection based on the associated information Determine whether can become a client.

  In addition, information on whether or not the BT-AV device itself can be a client can be put in a predetermined part of the service information (for example, “provider name” data of the service information in the BT standard). From the service information described in the BT table, the mobile phone 1 can determine whether each BT-AV device can be a client. Then, at the time of the determination in step S49, it may be determined whether or not it is possible to become a client based on the information in the BT table.

(D) BT-AV connection stored in the BT connection list storage unit 115b is recorded based on information that the client can record when connected from the BT-AV device by the client. When a device capable of BT-AV connection (for example, the BT headphones 200) is connected as a client when a BT connection is made between the device capable of being connected to the mobile phone 1 (for example, the mobile phone 1 is connected as a server), BT The connected BT-AV connectable device (for example, BT headphones 200) stored in the connection list storage unit 115b and information that can be used by the client are stored in association with each other. In step S49, whether or not the client can be determined is determined based on whether or not information that the client can record is recorded.

[(2-3) MP operation / SP / EP output]
Next, the MP operation / SP / EP output operation (hereinafter simply referred to as SP / EP output operation) will be described with reference to FIG. FIG. 9 is a diagram showing a flowchart when playing back music stored in the music information storage unit 115a by SP / EP output.

  First, in the SP / EP output operation, in the MP start operation, when (A) MP is activated and BGM playback is not being performed and BT-AV is not connected (<2> FIG. 8), and (B) MP is activated, This is performed when the BGM is not being reproduced, the BT-AV connection is not being waited, the BT-AV connection is not being performed, and the sound output destination setting is not a BT-AV device (<5> FIG. 8).

  In the SP / EP output operation, when the above operation is performed, reproduction (step S31-2) / stop (step S31-1) / pause (step S31-3) of music from the speaker 109 is performed. These are collectively referred to as SP / EP player playback (step S31). The reproduction (step S31-2) / stop (step S31-1) / pause (step S31-3) of the music can be changed by operating the key 6 and the electrostatic touch pad 14, respectively. Then, during playback of the SP / EP player, the control unit 101 calls a submenu by pressing the right soft key 66, and determines whether or not the sound output destination setting item screen has been called (step S32). If it is determined that the sound output destination setting item screen has not been called, SP / EP player playback is continued (“No” in step S32).

  On the other hand, when it is determined that the sound output setting item screen has been called, the control unit 101 displays a display as described in step S33 of FIG. 9 on the display 5 (step S33).

As items displayed on the display 5, all BT-AV devices in the peripheral device list stored in the BT connection list storage unit 115b and “BT connection OFF” are displayed. When the sound output destination is the current BT-AV device, only “BT connection OFF” is displayed, and when the current sound output destination is SP / EP, only “BT connection OFF” is displayed. You may display so that selection is impossible. Further, only the current sound output destination may be displayed so that it cannot be selected.

  Next, when any of the sound output destination settings is selected in step S33, the control unit 101 determines whether or not the selected sound output destination setting is a BT-AV device (step S34). . If the selected sound output destination setting is a BT-AV device (“Yes” in step S34), a BT-AV connection is started to that device (<7> FIG. 10).

  On the other hand, if it is determined that the selected sound output destination setting is not a BT-AV device (“No” in step S34), the sound output destination setting is set to a speaker or an earphone (SP / EP).

Then, this is stored in the sound output setting information storage unit 115c. And the control part 101 displays the display shown by step S36 on the display 5. FIG. Thereafter, the music reproduction operation (stop) is made by SP / EP output (step S31-1).

[(2-4) MP operation / BT-AV connected device output]
Next, MP operation / BT-AV connected device output (hereinafter referred to as BT-AV output) will be described. FIG. 11 is a flowchart for MP operation / BT-AV output.

  First, in the BT-AV output operation, in the MP start operation, when (A) MP is activated and BGM playback is in progress and BT-AV is connected (<1> FIG. 8), (B) MP is activated and BGM is activated. When not being reproduced, not waiting for the BT-AV connection, and being connected to the BT-AV (<3> FIG. 8), and (C) when the BT-AV output is successfully connected (<9>) This is performed in step S45 and step S54) of FIG.

  In the BT-AV output operation, when the above operation is performed, the music is reproduced (step S60-2) / stopped (step S60-1) / temporary from the BT-AV device (for example, the speaker 205 of the BT headphones 200). Stop (step S60-3) is performed. These are collectively referred to as BT-AV player playback (step 60). The transitions of music playback / stop / pause are as follows.

  First, when a reproduction operation (for example, pressing of the position of the sensor 87 of the electrostatic touch pad 14) is performed during the stop, the operation proceeds to the reproduction operation. When a pause operation (for example, pressing of the pause key 213 of the BT headphones 200) is performed during playback, the operation proceeds to a pause operation, and a playback restart operation (for example, pressing of the sensor 87 portion of the electrostatic touch pad 14) is performed. When it is done, the playback operation starts.

  If a stop operation is performed during the reproduction operation, it is determined whether or not the stop operation is a stop operation from the BT-AV device (step S60-4). When the operation is not the stop operation from the BT-AV device but the stop operation from the mobile phone 1 (“No” in step S60-4), the operation proceeds to the stop operation (step S60-1).

  On the other hand, when a stop operation from the BT-AV device (for example, pressing of the stop key 212 of the BT headphones 200) is performed during the playback operation, the BT-AV connection is disconnected, the client operation or the server operation is terminated, and the BT-AV is terminated. Transition to AV connection termination operation.

  It should be noted that during BT-AV player playback (step S60), operations prohibited during BT-AV connection (for example, volume adjustment operation / fast forward / rewind operation by the key 6 of the mobile phone 1 and the electrostatic touch pad 14) The operation that is not reflected in the control on the BT headphone side is prohibited even if the operation is performed), and it is determined whether or not the operation has been performed (step S61). Returning to the reproduction ("No"), if it is determined that the prohibited operation has been performed, the display shown in step S62 is displayed on the display 5 and the operation is invalidated (step S62). Then, after a predetermined time has elapsed, the BT-AV player playback is resumed.

  During playback of the BT-AV player (step S60), the control unit 101 calls a submenu by pressing the right soft key 66, and determines whether or not the sound output destination setting item screen is called (step S66). ). When it is determined that the sound output destination setting item screen has not been called, the BT-AV player playback is continued (“No” in step S66).

  On the other hand, when it is determined that the sound output setting item screen has been called, the control unit 101 displays the display as described in step S33 in FIG. 8 on the display 5 (<10> FIG. 9).

  In the embodiment of the present invention, the mobile phone 1 has been described as an example. However, the present invention is not limited to this and can be applied to other mobile communication devices (for example, PDA, PHS, etc.). Moreover, although the embodiment has been described for the BT, other means by other short-range wireless communication or wired communication may be used. For example, in short-range wireless communication, IrDA, wireless LAN, or the like may be used. In wired communication, a LAN interface such as RS-232, USB, IEEE 1394, and 10Base-T may be used.

  According to the embodiment of the present invention, even when an incoming call occurs in the mobile phone 1 during BT connection to a BT-AV device and reproduction of music information, ringing tone information can be sent to the BT-AV device. It is possible to know the occurrence of an incoming call that interrupts.
