Note that the PIN code may be set not to be exchanged at the stage of obtaining the list, and the PIN code may be exchanged at the stage of establishing a connection in the flow of FIGS. 7 to 12 described later.

Next, a flow when music reproduction is performed 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) MP start operation (FIG. 7)
(2) BT-AV connection start operation (FIG. 9)
(3) MP operation / speaker / earphone output (hereinafter referred to as SP / EP output) (FIG. 8)
(4) MP operation / BT-AV connected device output (Fig. 10)
(5) BT-AV connection end operation / BT-AV connection standby operation (FIG. 11)
Hereinafter, each operation will be described separately. Note that description will be made with reference to FIG. FIG. 12 shows an example of the display screen of the display 5 when the mobile phone 1 is operating.

[(1) MP start operation]
The MP start operation will be described. FIG. 7 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 the BGM is not being played back ("No"), it is determined whether the BT-AV connection is being waited (step S14).

  Next, when it is determined in step S13 that the BT-AV connection is being made (“Yes”), the playback of the music data of BGM has simply shifted to the playback 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. 10).

  On the other hand, if it is determined in step S13 that the BT-AV connection is not being established ("No"), the music data 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 merely shifted to FGM playback, and sound is output without interruption from the speaker 109 or the 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. 8).

  If it is determined in step S14 that the BT-AV connection is being waited or not (step S14 “Yes”), the BT-AV connection is determined. The standby is continued, that is, the connection wait is continued as a server (<6>, step S50 in FIG. 9).

  On the other hand, if it is determined in step S14 that BT-AV standby is in progress, it is determined that BT-AV connection is not in standby ("No"), whether BT-AV connection is in progress. Is determined (step S15).

  If it is determined that the BT-AV connection is being made (step S15 “Yes”), a player action is performed on the output destination during the BT-AV connection (<3>, step S60 in FIG. 10). 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 being established (step S15 “No”), the sound output destination setting stored in the sound output setting information storage unit 115c is read out to the BT-AV device. It is determined whether it is set (step S16).

  In step S16, if it is determined that the sound output destination setting stored in the sound output setting information storage unit 115c is not a BT-AV device ("No"), the player action is performed by SP / EP connection. (<5>, go to step S31 in FIG. 8). 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, if the sound output destination setting stored in the sound output setting information storage unit 115c is set in the BT-AV device in step S16 (step S16 “Yes”), the set BT-AV device. BT-AV connection is started as a client (<4>, proceeding to step S41 in FIG. 9). 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 starting with the flow described in the flowchart of FIG. That is, for example, when the MP is activated in step S11, when the BGM is being played back and the BT-AV is connected, it may be designed to make a transition to <1> (FIG. 10). Similarly, for example, when MP is activated in step S11, the BGM playback is not being performed, the BT-AV connection is not being waited, the BT-AV connection is not being performed, and the sound output setting information storage unit 115c is set. Is set in the BT-AV device, it may be designed to make a transition to <4> (FIG. 9).

  When MP is activated in step S11, if the BGM is not being played back, the BT-AV connection is not in standby, and the BT-AV connection is not established, <4 according to the setting of the sound output setting information storage unit 115c. > (FIG. 9) or <5> (FIG. 8), the playback here may be either FGM or BGM. For example, in the case of BGM, music can be played back while continuing other operations in the foreground (for example, e-mail creation, etc.), and user convenience can be further improved.

When MP is activated in step S11, if the BGM is not being played, BT-AV is not being standby, BT-AV is being connected, and music is being played by BGM, the result determined in step S16 Regardless, the sound output destination may always be SP / EP, or BGM playback may be prohibited when the sound output destination setting is a BT-AV device (“Yes” in step S16). Good. In this way, when another operation (for example, e-mail creation) is performed in the foreground, the BT-AV connection start operation is not executed in the background, so that the user can more easily change the operation state. To be able to grasp.

[(2) BT-AV connection start operation]
Next, the BT-AV connection start operation will be described with reference to FIG. FIG. 9 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 connection is not being standby, BT-AV connection is not being performed, and sound output is performed When the setting information storage unit 115c is set in the BT-AV device (transition from <4> in FIG. 7), 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 BT-AV device (transition from <7> in FIG. 8).

  First, when the BT-AV connection start operation is performed as described above, as a client to a BT-AV device set as a sound output destination (for example, described as being set in the BT headphones 200 below). A BT-AV connection operation (for example, connection using an AV profile) is started (step S41). At that time, the control unit 101 controls the display 5 to display the screen shown in FIG. 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 control unit 101 causes the display 5 to perform the display shown in FIG. Then, the sound output setting is set as SP / EP connection (transition to <8> in FIG. 8).

  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 action (stop) is performed by BT-AV connection (<9> transition to step S60-1 in FIG. 10). In that case, the control unit 101 displays a display as shown in FIG.

  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 connection is a device that can be a client (“Yes” in step S49), then the server starts waiting 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.

  Further, the control unit 101 displays the display shown in FIG.

As a result, the user can notify the user when the power of the BT-AV device to be connected is inadvertently turned off, and the user can turn on the power of the BT-AV device. Can be urged.

  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). Then, the control unit 101 displays the display shown in FIG. 12F on the display 5, and further sets the sound output setting as SP / EP connection (transition to <8> in FIG. 8).

  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 action (stop) is performed by BT-AV connection (<9> transition to step S60-1 in FIG. 10). In that case, the control unit 101 displays a display as shown in FIG.

  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). Thereafter, the control unit 101 displays the display shown in FIG. 12D on the display 5, and further sets the sound output setting as SP / EP connection (<8> proceeds to step S35 in FIG. 8).

  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 step S49 “No”), the control unit 101 displays the displays shown in FIGS. 12A and 12B on the display 5, respectively, and further sets the sound output setting as SP / EP connection. (<8> Transition to step S35 in FIG. 8).

  In step S48, if the reason for the connection failure is authentication failure (“Yes”), the process proceeds to <8> (FIG. 8) and the connection is not limited to the SP / EP connection setting. 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, BT headphones 200) is connected as a client when performing BT connection between the device capable of mobile phone 1 and mobile phone 1 (when mobile phone 1 is connected as a server)
The connected BT-AV connectable device (for example, BT headphones 200) stored in the BT connection list storage unit 115b is associated with information that can be used by the client. 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.

[(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. 8 is a diagram showing a flowchart for reproducing the 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. 7), (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 established, and the sound output destination setting is not a BT-AV device (<5> FIG. 7).

  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 soft key right 66, and determines whether or not the sound output destination setting item screen is 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 in FIG. 8 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 for that device (<7> FIG. 9).

  On the other hand, if it is determined that the selected sound output destination setting is not a BT-AV device (“No” at step S34), the sound output destination setting is set to the speaker 109 or the earphone (SP / EP) (step S35). ).

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).

[(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. 10 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. 7), (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. 7), and (C) when the BT-AV output has been successfully connected (<9>) 9 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 S60). 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 end operation (<11>, transition to step S73 of FIG. 11).

  Then, during playback of the BT-AV player (step S60), operations prohibited while the BT-AV is connected (for example, volume adjustment operation / fast forward / rewind operation by the key 6 of the mobile phone 1, the electrostatic touch pad 14) The operation that is not reflected in the control on the BT headphone 200 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 player 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 soft key right 66 to determine 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. 8).

[(5) BT-AV connection end operation / BT-AV connection standby operation]
Next, a BT-AV connection end operation and a BT-AV connection standby operation will be described with reference to FIG. FIG. 11 is a flowchart when starting the BT-AV connection start operation and when shifting to the standby operation again. The BT-AV connection end operation is (A) when an MP end operation is performed by the key 6 of the mobile phone 1 when music is being played back during the BT-AV connection (step S60 in FIG. 10) (transition from step S71) ), And (B) a stop operation (“Yes” in step S60-4, <11>) is performed from the BT-AV device while the music is being played back during the BT-AV connection (step S60 in FIG. 10). In case (transition from step S73).

  First, it is determined whether or not the MP end operation has been performed by the key 6 of the mobile phone 1 when the music is being reproduced during the (A) BT-AV connection (step S60 in FIG. 10) (step S71). When the end operation is performed (“Yes”), a display as shown in step S72 is displayed on the display 5, and the user is prompted to select whether to continue playback with BGM, to end, or to cancel the end. (Step S72). If a cancel operation is performed, BT-AV player playback is resumed. When it is selected to continue playback with BGM (when [BGM playback] is selected), the display on the display 5 returns to the standby screen, but playback continues with BGM (step S74). Note that even during playback by BGM, it is possible to transition to each of the BGM stop state and BGM pause state by an operation using the key 6, the side key 7 or the electrostatic touch pad 14.

  On the other hand, when the display shown in step S72 is displayed on the display 5, an operation for ending MP (for example, pressing of the power key 71) is performed, and a BGM playback end operation is performed during BGM playback. Terminates the music playback operation, and further terminates the client operation or server operation that has been connected to the BT-AV (step S73). As described above, even when a stop operation is performed from a device connected to the BT-AV while the BT-AV player is being played (in the case of (B) above), the music playback operation is terminated. Further, the client operation or server operation that has been connected to the BT-AV is terminated.

  Next, it is determined whether or not the BT-AV device that has been connected so far can operate as a client (step S75). Since this determination method is the same as the determination method in step S49 described above, description thereof is omitted.

  Next, when it is determined that the connected BT-AV device can become a client (“Yes” in step S75), the server starts waiting for BT-AV connection (step S76). As the BT-AV 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 attempted to connect as a client may be set, or the BT connection list storage unit Connection wait may be performed for all BT-AV devices stored in 115b (in this case, not only the BT headphones 200 but also other devices such as the BT component 300).

  Next, it is determined whether or not a BT-AV connection has been established by the server operation (step S77). If it is determined that the connection could not be made (“No”), it is determined whether or not a predetermined time has elapsed (timed out) from the time when the server waited for connection (step S78). If it is determined that the predetermined time has not yet passed (“No” in step S78), a BT-AV standby screen as shown in step S79 is displayed, and the process returns again to step S77, where BT-AV is displayed. Determine if connection was successful.

  On the other hand, if the BT-AV connection is established in step S77 (“Yes”), 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 S77). S80). Thereafter, when BGM playback is performed by BT-AV connection, playback by BGM shown in step S74 is performed (transition to <13>).

  In step S78, when the predetermined time has passed (when timed out) ("Yes"), the BT-AV connection operation connected as the server is terminated (step S82). Then, the screen returns to the standby screen (step S83).

  During the BGM playback in step S74, the MP activation operation is performed when the BT-AV connection standby screen in step S79, the BGM playback in step S81 is not performed, and when the standby screen in step S83 is displayed. Then, the operation is again performed as MP activation (<12> transition to FIG. 7).

  In the BT-AV connection standby screen in step S79, the BT-AV connection wait may be stopped from a menu other than MP (for example, BT setting menu). When the BT-AV connection waiting is stopped by this operation, the sound output destination information stored in the sound output setting information storage unit 115c may be rewritten to the SP / EP setting. Alternatively, only the BT-AV connection waiting may be stopped without changing the sound output destination information.

  In the BT-AV connection standby screen in step S79, when a music playback operation is executed with the electrostatic touch pad 14, BGM playback is prohibited or BGM playback is performed with the sound output destination set to SP / EP. You may make it do. By doing so, the BT-AV connection start operation is not executed in the background, so that the user can grasp the operation state more easily.

  FIG. 13 is an explanatory diagram when a link loss occurs in the case of BT-AV connection. The BT-AV link loss is due to the distance between the mobile phone 1 and the BT-AV device (for example, the BT headphones 200) being increased. Specifically, when the sound output is set in step S33, or It is conceivable that the MP is activated during the BT-AV connection in step S60. At this time, if a link loss occurs, for example, the display shown in step S90 of FIG. 13 is displayed on the display 5, and then the sound output destination setting is set to SP / EP (<8> transition to FIG. 8).

  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, when a BT-AV connection is made, a connection is attempted as a client. When the connection destination BT-AV device is turned off, the server can be used as a server. You can connect again. As a result, the user can connect to the BT-AV device with fewer operations.

In addition, when the client operation or the server operation is terminated, if the BT-AV device connected as the sound output destination can become the client, the mobile device may start waiting for connection (waiting for BT-AV connection) in the server mode. Therefore, since the mobile phone 1 does not stand by for BT-AV connection with respect to BT-AV devices that realize only server operation, current consumption can be suppressed.
