  However, the volume of a television receiver or the like that reproduces input video / audio differs depending on whether the video / audio input from the mobile communication terminal is played back or when the broadcast TV program is received and played back by the built-in tuner. There is a case. Specifically, for example, when switching from the reproduction of a television program to the reproduction of video and audio of a mobile communication terminal, the volume may be significantly reduced from the point of switching. In order to reproduce this at an appropriate volume, the user must perform an operation to increase the volume with the remote control or the like of the television receiver after switching. Further, when the volume is increased to return to the reproduction of the television program next time, the television program is reproduced at a high volume, and a remote control operation for decreasing the volume must be performed here.

  Accordingly, an object of the present invention is to provide a portable communication terminal that eliminates the need for a volume adjustment operation on an external device by a user before and after outputting video and audio to an external device such as a television receiver.

  The mobile communication terminal of the present invention that achieves the above object stores content storage means for storing content to be transmitted to a television receiver for reproduction, and a first volume level to be set for the television receiver.

The value of the first volume level in the storage means is updated. As a result, the user does not need to perform only the operation of updating the value of the first volume level, and the user can perform the adjustment operation while checking the volume with his / her ear during the reproduction of the content. Is updated.

  In addition, the updating unit further includes the second volume stored in the second volume storage unit in response to an instruction indicated by a signal transmitted by the user volume adjustment unit after the transmission of the content by the transmission unit. The level value may be updated.

  According to this configuration, an instruction for volume adjustment by a user operation performed after content transmission is transmitted to the television receiver as a remote control signal, and at the same time, the second volume level of the second volume storage means is responded to the instruction. The value of is updated.

  The transmission means includes connection means for wired connection with the television receiver for content transmission, and the first sound volume adjustment means detects the first connection when the connection means detects a wired connection.

It may be a remote control signal indicating an instruction to raise or lower.

  According to this configuration, it is possible to store the relative difference in volume level before and after switching of the audio input source of the television receiver, and to adjust the volume level when switching the audio input source according to the relative difference.

  In addition, after the transmission of the signal by the first sound volume adjustment unit, the transmission unit generates and transmits a signal to be reproduced by the television receiver from the content, and the portable communication terminal further transmits the transmission A stop means for stopping the generation of the signal by the transmission means may be provided when an interruption relating to a voice call or data communication is received while the content is being transmitted by the means.

  With this configuration, the generation of the content signal is automatically stopped when an incoming call is received, so that it is possible to save the user from performing a stop operation.

  The interruption relating to the voice call or data communication may be any of incoming voice call, mail reception, and content data reception.

  With this configuration, when the mobile communication terminal receives any voice call, mail reception, or content data reception, the signal generation by the transmission means is automatically stopped, and the user's trouble of the stop operation is reduced. It can be lost.

The portable communication terminal further sets a third volume level lower than the first volume level when receiving an interruption related to a voice call or data communication while the content is being transmitted by the transmission unit. For this purpose, there may be provided third volume adjusting means for transmitting a signal for transmitting to the television receiver.

  With this configuration, when a user starts a call in response to an incoming call, even if a surrounding person plays a TV program by changing a channel or the like, the call is disturbed. It is possible to prevent the program from being played at a high volume.

  The portable communication terminal further transmits a signal for setting a fourth volume level higher than the third volume level to the television receiver when the processing related to the interruption related to the voice call or the data communication ends. You may provide a 4th volume adjustment means.

  With this configuration, even when the volume is temporarily lowered by the third volume adjusting means, the volume can be increased when the processing related to the interruption is completed. If the fourth volume level is made the same as the volume level before interruption, it can be returned to the original volume level when the processing related to the interruption is completed. The end of the process related to the interruption is specifically, for example, when the interruption is an incoming voice call and the voice call is ended and the connection related to the call is disconnected. In the case of mail reception, for example, when an operation indicating that the user has opened and confirmed the mail is detected, or when a reply mail for the received mail is transmitted. In the case of content reception, for example, it is when an operation indicating that the confirmation of the content has been completed is detected.

  The portable communication terminal may further include a stopping unit that stops transmission of the content of the transmission unit when receiving an interrupt related to a voice call or data communication while the content is being transmitted by the transmission unit. .

Hereinafter, content or video / audio held in the content storage unit 115 is simply referred to as content unless it is particularly necessary to distinguish them.

  The content processing unit 120 performs decoding processing of compressed content, changes in resolution, and the like in accordance with the screen display and audio output specifications of the television receiver 60 or the reproduction unit 130 that reproduces content. Then, the processed content is output to the television output unit 125 when in the television output mode, and to the reproduction unit 130 when not in the television output mode.

  The television output unit 125 is connected to the television receiver 60 via the cable 80 and transmits the content output from the content processing unit 120 to the television receiver 60 in the television output mode.

  The reproduction unit 130 includes a display, a speaker, and the like, and reproduces content output from the content processing unit 120 when not in the television output mode.

  The volume control unit 135 has a remote control function, a volume control function related to the television output mode, and a user setting function for setting values that are the basis of volume control.

  These functions will be described in order below.

  The remote control function is a function for adjusting the volume of the television receiver 60 by transmitting an infrared remote control signal in response to a user operation. When receiving a user operation indicating an instruction to increase or decrease the volume from the operation unit 140, the volume control unit 135 instructs the infrared communication unit 145 to output an infrared remote control signal corresponding to the user operation. This function functions not only in the television output mode but also when not in the television output mode, that is, when the television receiver 60 is reproducing a television program.

  The volume control function related to the TV output mode is that the infrared remote control signal is transmitted to the volume setting storage unit 155 based on the set value at the start and end of the TV output mode, and the volume of the TV receiver 60 is adjusted. It is a function to perform. Accordingly, an object is to eliminate the difference in volume level before and after the input source of the audio to the television receiver 60 is switched.

  In this function, there is a connection detector 150 to detect the start and end of the TV output mode. The connection detection unit 150 automatically detects that the television output unit 125 and the television receiver 60 are connected by the cable 80 and that the connection is disconnected by an electrical signal change, and detects that the connection is detected at the time of detection. To the volume control unit 135.

  When the connection detection unit 150 is notified that the cable 80 has been connected, the volume control unit 135 instructs the infrared communication unit 156 to transmit an infrared remote control signal, and adjusts the volume of the television receiver 60. Do. The television output unit 125 starts transmitting the content after transmitting the infrared remote control signal.

  Further, when the volume control unit 135 is notified from the connection detection unit 150 that it has detected that the connection of the cable 80 has been disconnected, the volume control unit 135 instructs the infrared communication unit 156 to transmit an infrared remote control signal, and the television receiver Adjust the volume of 60.

  Here, the setting value that is the basis of the volume adjustment is stored in the volume setting storage unit 155.

  The sound volume setting storage unit 155 includes an initial setting storage unit 160 that stores setting values in advance and cannot be rewritten, and a user setting storage unit 165 that can be rewritten in response to a user operation.

  In the default state, the volume control unit 135 performs volume adjustment before and after the television output mode using the stored contents of the initial setting storage unit 160. The default state means that no valid value is recorded in the user setting storage unit 165 yet.

  The volume control unit 135 records the setting value in the user setting storage unit 165 in accordance with a user operation. This is a user setting function of a set value that is a basis for volume control.

  When a value is recorded in the user setting storage unit 165 by a user operation, thereafter, the volume control unit 135 performs volume adjustment before and after the television output mode using the stored contents of the user setting storage unit 165.

  3A and 3B show an example of the contents stored in the volume setting storage unit 155. FIG.

  FIG. 3A shows an example of the contents stored in the initial setting storage unit 160.

  In the figure, the initial setting storage unit 160 includes a volume level width (T1), a volume at the time of television output (T2), and a volume at the end of the television output (T3).

  The volume level width (T1) indicates the volume level width of the television receiver 60. However, since the volume level width varies depending on the type of television receiver, the volume level width is assumed here, not the actual volume level width. You may use the volume level width most adopted by each model, and the largest volume level width among each model. Here, 20 is stored as the volume level width (T1).

  The volume (T2) at the time of television output indicates a volume level that should be set for the television receiver 60 when content is reproduced in the television output mode. Here, 16 is stored. The volume (T2) is desirably a volume level that is assumed to be supported by most users as a volume level at the time of content reproduction in the television output mode.

  The volume (T3) after the television output ends indicates the volume level that should be set for the television receiver 60 after the television output mode ends, that is, when a television program or the like is reproduced. Here, 12 is stored. Similarly to the sound volume (T2), this sound volume (T3) is desirably a sound volume level that is assumed to be supported by most users as a sound volume level in content reproduction in the television output mode.

  FIG. 3B shows an example of the contents stored in the user setting storage unit 165.

  In the figure, the user setting storage unit 160 includes a volume level width (T4), a volume at the time of television output (T5), and a volume after the end of the television output (T6).

  The volume level width (T4) indicates the volume level width of the television receiver 60 set by the user. Here, 20 is stored as the volume level width (T4).

  The volume at the time of television output (T5) indicates the volume level that should be set for the television receiver 60 during content reproduction in the television output mode, and is set by the user. Here, 18 is stored.

  The volume (T6) after the end of the TV output indicates the volume level that should be set for the TV receiver 60 after the end of the TV output mode, that is, when a TV program or the like is played back, and is set by the user. . Here, 11 is stored.

How these set values are used will be described with reference to FIG.
<Operation>
FIG. 4A shows a processing procedure at the start of the television output mode.

  In FIG. 9A, the connection detection unit 150 detects that the television output unit 125 and the television receiver 60 are connected by the cable 80, and notifies the sound volume control unit 135 to that effect (step S41).

Upon receiving the notification, the volume control unit 135 reads the volume level width (T1) from the initial setting storage unit 160 in FIG. Then, the infrared communication unit 145 is instructed to output an infrared remote control signal indicating an instruction to lower the volume by the volume level width (T1) (step S42). More specifically, this infrared remote control signal is a signal string formed by repeating a signal for instructing to lower the volume level by an amount corresponding to the volume level width (T1). In the example of FIG. 3A, since the infrared remote control signal is (T1) = 20, a signal sequence in which a signal for instructing to reduce the volume is repeated 20 times. By the operation of lowering the volume, the volume level of the television receiver 60 becomes the lowest value.

  Next, the volume control unit 135 reads the volume (T2) at the time of television output from the initial setting storage unit 160 in FIG. Then, the infrared communication unit 145 is instructed to output an infrared remote control signal indicating an instruction to increase the volume to the volume (T2) (step S43). More specifically, the infrared remote control signal is a signal string formed by repeating an instruction signal for raising the volume level by an amount corresponding to the volume level (T2). In the example of FIG. 3A, the infrared remote control signal is a signal sequence in which a signal for instructing to increase the volume is repeated 16 times.

  After the infrared remote control signal in step S43 is output, the television output unit 125 starts transmission of content through the cable 80 (step S44). Then, the transmitted content is reproduced by the television receiver 60 at the volume (T2) set in step S43.

  FIG. 4B shows a processing procedure at the end of the television output mode.

  In FIG. 5B, the connection detection unit 150 detects that the cable 80 is disconnected from the television output unit 125 and the television receiver 60, and notifies the volume control unit 135 of the fact (step). S45).

  Upon receiving the notification, the volume control unit 135 reads the volume level width (T1) from the initial setting storage unit 160 in FIG. Then, the infrared communication unit 145 is instructed to output an infrared remote control signal indicating an instruction to lower the volume by the volume level width (T1) (step S46). More specifically, this infrared remote control signal is a signal string formed by repeating a signal for instructing to lower the volume level by an amount corresponding to the volume level width (T1). In the example of FIG. 3A, the infrared remote control signal is a signal sequence in which an instruction signal for lowering the volume is repeated 20 times. By the operation of lowering the volume, the volume level of the television receiver 60 becomes the lowest value.

  Next, the volume control unit 135 reads the volume (T3) after the end of the television output from the initial setting storage unit 160 in FIG. Then, the infrared communication unit 145 is instructed to output an infrared remote control signal indicating an instruction to increase the volume to the volume (T3) (step S47). More specifically, the infrared remote control signal is a signal string formed by repeating a signal for increasing the volume level by an amount corresponding to the volume level (T3). In the example of FIG. 3A, the infrared remote control signal is a signal sequence obtained by repeating a signal to increase the volume 12 times.

  In this way, when the TV output mode starts and when the TV output mode ends, the volume level of the television receiver 60 is adjusted based on the stored contents of the initial setting storage unit 160. Therefore, an appropriate value is stored in the initial setting storage unit 160. By doing so, it is possible to suppress the level difference of the volume level due to the switching of the audio input source of the television receiver 60.

  FIG. 5 shows a processing procedure for user setting.

  When receiving the selection of the user setting menu for the user setting storage unit 165 by the user operation (step S51), the volume control unit 135 displays the user setting screen (step S52). The user setting screen is, for example, a text box for acquiring input of values by the user for three items of volume level width (T4), volume at the time of television output (T5), and volume after the end of television output (T6). It is comprised with GUI.

  Through this user setting screen, the user can set a volume or the like of each item by inputting a value in a text box or the like of each item (step S53).

When the user receives an operation such as pressing the registration key (step S54), the volume control unit 135 acquires the value of each input item and updates the value of each item in the user setting storage unit 165 with the acquired value. (Step S55).

  When the value of the user setting storage unit 165 is updated in this way, thereafter, the volume control unit 135 uses the value of the user setting storage unit 165 instead of the value of the initial setting storage unit 165, as shown in FIGS. ). That is, in FIGS. 5A and 5B, the volume level width (T4) is used instead of the volume level width (T1), the volume (T5) is used instead of the volume (T2), and the volume (T3) is used instead. The processing is performed using the volume (T6).

  By using the user setting, the user can view the playback in the television output mode and the playback after the television output mode ends at the user's favorite volume.

  The user setting value set by the above method may be updated as follows.

  FIG. 6 shows the procedure for updating the user value setting.

  After starting the television output mode (step S61), the volume control unit 135 transmits an infrared remote control signal according to the user operation by the remote control function, and adjusts the volume level of the television receiver 60 (step S62).

  At this time, the volume control unit 135 updates the value of the volume (T5) at the time of television output in the user setting storage unit 165 according to the amount of adjustment of the volume level by the user operation (step S63). More specifically, when a remote control signal is transmitted by a user operation and the sound volume level changes to 19 as a result when the sound volume level is 16 and the sound volume level is changed to 19, the sound volume control unit 135 The value of the volume 165 (T5) is updated to 19.

  As described above, the user setting storage unit 165 can be updated in accordance with the remote control operation using the mobile phone 100 of the user, so that the user can check the volume at the time of TV output while checking the volume at the time of the TV output mode. (T5) can be set.

  When the volume level of the television receiver 60 is adjusted by the user's remote control operation after the television output mode ends, the value of the volume (T6) after the television output ends is updated according to the adjustment amount. You may do it.

  As described above, the volume level is adjusted at the start and end of the TV output mode. In addition, when the mobile phone 100 receives an incoming call related to a voice call during TV output, the following operation is performed. Process.

  That is, when the wireless communication unit 105 receives an incoming signal from the base station while the content is being reproduced on the television receiver 60 in the television output mode, the content processing unit 120 performs the content decoding process or the television output. The output to the unit 125 is stopped, and a signal to stop the reproduction of content is transmitted to the television receiver 60 through the television output unit 125. At substantially the same time, the volume control unit 135 instructs the infrared communication unit 145 to output an infrared remote control signal that instructs the television receiver 60 to mute. Here, instead of instructing to mute, an instruction to lower the volume level by an amount corresponding to the volume level width (T1), a volume level (T2) or (T4), or a volume level lower than the current volume level. It may be an instruction to lower the value.

  As a result, the content playback is automatically stopped when an incoming call is received, and the user does not have to perform the stop operation. In addition, by reducing the volume by muting, etc., even if a person around you plays the TV program by changing the channel during the call, the program is played at a high volume that will disturb the call. Can be prevented.

  Further, when detecting the end of the call of the wireless communication unit 105, the volume control unit 135 may instruct the infrared communication unit 145 to perform a process of returning the lowered volume level to the volume at the time of content playback.

  Specifically, in the returning process, when returning to the sound volume level (T2), the sound volume control unit 135 first instructs the infrared communication unit 145 to instruct to decrease the sound volume by the sound volume level width (T1). Infrared remote control signal is output, and then an infrared remote control signal indicating an instruction to increase the volume is output to the volume (T2). Instead of returning to the volume level (T2), the volume level may be raised to the volume level (T3), (T5), (T6) or a predetermined volume level. The level may be stored, and when the call ends, a process for returning to the stored volume level may be performed.

  At this time, the content processing unit 120 may be configured to resume the content reproduction by the television output from the content reproduction stop position at the time of detecting the incoming call.

  In the above, the processing when an incoming call related to a voice call is received during TV output has been described. However, the process is not limited to an incoming call related to a voice call during TV output. The above processing may also be performed when data is received.

  In short, when the wireless communication unit 105 receives an interruption related to voice communication or data communication during TV output from the base station, the content processing unit 120 stops the content decoding process and output to the TV output unit 125, The volume control unit 135 causes the infrared communication unit 145 to output an infrared remote control signal instructing to lower the volume level.

  Further, when the interruption operation such as the end of the call, the completion of the mail reception, or the completion of the content reception ends, the volume control unit 135 instructs the infrared communication unit 145 to set the lowered volume level at the time of content playback. Perform processing to restore volume. The volume control unit 135 sets the volume level in response to completion of a series of operations related to mail reception, such as an operation of opening the received mail or an operation of creating a reply mail for the mail instead of completion of the mail reception. You may perform the process to return. Further, instead of the completion of content reception, processing for returning the sound volume level upon completion of a series of operations related to content reception, such as an operation for confirming received content, may be performed.

Note that the mobile phone 100 configured as described above may be configured as follows.
(1) The connection detection unit 150 is configured to automatically detect that the cable 80 is connected and disconnected, but detects a user operation indicating the start and end of the TV output mode. You may comprise.
(2) The initial setting storage unit 160 stores a relative difference between the volume level outside the TV output mode and the volume level during the TV output mode, and the volume control unit 135 receives an infrared remote control signal corresponding to the relative difference as an infrared ray. You may make it output to the communication part 145 and you may comprise so that volume adjustment at the time of the television output mode start and completion may be performed. The same applies to the user setting storage unit 165.
(3) The infrared communication unit 145 may use another short-range wireless communication method such as Blue tooth instead of performing infrared communication.
(4) In this embodiment, the video / audio signal output from the mobile phone 100 to the television receiver 60 may be encoded by an encoding method such as the MPEG method. The decoded video / audio signal may be decoded by a decoder and then output to a speaker and a display.

  The present invention can be used for a mobile phone, a mobile information terminal, and the like that are provided with a video / audio output mechanism to an external device such as a television receiver.
