Description

  The present invention relates to a remote control device, a remote control method, a control program, and a recording medium for performing sound volume control of a device having a sound output function, such as a broadcast receiving device or an audio playback device that receives a broadcast program, by remote operation.

  In a broadcast receiving apparatus that receives a broadcast program, it is general to store the volume when the power is turned off, and reproduce the stored volume as it is when the power is turned on next time. In recent years, a technique has been proposed in which the volume is set under setting conditions suitable for the user, instead of reproducing the volume when the power is turned off when the power is turned on.

  For example, Patent Document 1 proposes a television receiver that stores a setting value of a user's daily sound volume in a memory for each time and reads and sets a sound volume corresponding to the time at the time of power-on from the memory. ing. Moreover, in patent document 2, the volume of yesterday and the day before yesterday is memorize | stored, the volume of yesterday is set when the difference is smaller than a predetermined value, and the difference is larger than a predetermined value, the volume at the time of the last power-off There have been proposed a remote controller and a television receiver for setting the.

  The timer 23 is a general timer that outputs time information. In response to the time measurement request from the control unit 26, the time measurement unit 23 notifies the control unit 26 of the time at that time as time information.

  The ambient sound pressure measurement unit 24 is a general microphone that measures the sound pressure level, receives the sound pressure level measurement request from the control unit 26, measures the sound pressure level of the ambient sound of the remote controller 1, and measures it. The control unit 26 is notified of the result as ambient sound pressure level information.

  The memory 25 is a general storage unit such as a semiconductor memory. In the first embodiment, an SRAM is used to reduce power consumption. In the memory 25, power supply state information indicating the current “ON” or “OFF” state of the broadcast receiving device 2, channel selection information indicating the station number of the broadcast program last set by the remote controller 1, and setting in the broadcast receiving device 2 Setting volume information indicating the volume being set is stored. In the first embodiment, the memory 25 stores a volume associated with time information and ambient sound pressure level information.

  The control unit 26 controls the entire remote controller 1. The control unit 26 mainly generates control information corresponding to the operation button information notified from the input unit 21 and notifies the communication unit 22 of the control information. In the first embodiment, the control unit 26 includes a power supply state monitoring unit 31, a channel control unit 32, and a volume control unit 33.

  Here, the volume setting table is created based on the “ambient sound pressure level-volume characteristic graph” obtained by plotting the ambient sound pressure level and the sound volume set in the broadcast receiving apparatus 2 for each predetermined time period. It is a table. An example of the “ambient sound pressure level-volume characteristic graph” is shown in FIG. 3A, and an example of the volume setting table is shown in FIG. In FIG. 3A, the “ambient sound pressure level-volume characteristic graph” shows ambient sound pressure levels for four time zones of 0 to 4 o'clock, 5 to 8 o'clock, 9 to 20 o'clock, and 21 to 24 o'clock. A characteristic curve obtained from a plot of the volume set in the broadcast receiving apparatus 2 is shown.

Then, in the volume setting table, the volume corresponding to the ambient sound pressure level at the center of the predetermined level range is obtained from the “ambient sound pressure level-volume characteristic graph” and registered as the volume corresponding to the ambient sound pressure level range. ing.

  For example, in FIGS. 3A and 3B, when the power of the broadcast receiving apparatus 2 is turned on by pressing the power button 11 of the remote controller 1 at time “21:30”, the ambient sound pressure measurement unit 24 When the measured ambient sound pressure level is included in the “ambient sound pressure level range c”, “sound volume d3” is set in the broadcast receiving device 2.

  Next, the operation of the remote controller 1 when each operation button is pressed will be described with reference to FIGS. First, the operation flow of the remote controller 1 when the user presses the power button 11 of the remote controller 1 will be described with reference to FIG.

  In FIG. 4, when the user presses the power button 11, the input unit 21 detects that the power button 11 has been pressed (step 101), and “presses the power button” on the power state monitoring unit 31 of the control unit 26. Notification is made (step 102). When notified of “press power button”, the power supply state monitoring unit 31 reads the power supply state information stored in the memory 25. If the read power supply state information is “ON”, the power supply state monitoring unit 31 sets “OFF”. "" Is updated to "ON" (step 103), and the updated power status information is notified to the communication unit 22 (step 104).

  Next, the updated power supply state information is confirmed (step 105). If the power supply state information is “ON”, the control unit 26 sends a sound pressure level measurement request to the ambient sound pressure measurement unit 24 and the time measurement unit 23. Make a timing request. In response to the sound pressure level measurement request, the ambient sound pressure measurement unit 24 measures the sound pressure level of the ambient sound of the remote controller 1, and notifies the sound volume control unit 33 of the measurement result as ambient sound pressure level information (step 106). . The time measuring unit 23 receives the time measurement request, and notifies the volume control unit 33 of the time at that time as time information (step 107). The volume control unit 33 reads the volume corresponding to the received ambient sound pressure level information and time information with reference to the volume setting table stored in the memory 25, and notifies the communication unit 22 as the set volume information ( Step 108). Further, the set volume information stored in the memory 25 is updated by changing to the new set volume information (step 109).

  Further, the control unit 26 controls the channel control unit 32 to read channel selection information from the memory 25 and notify the communication unit 22 of the read channel selection information (step 110). The communication unit 22 modulates infrared light based on the notified power state information (power ON), set volume information, and channel selection information, and outputs the modulated infrared signal from the signal output unit 14 as a control signal of the broadcast receiving device 2 (step 111). .

  On the other hand, if the updated power supply state information is “OFF” in step 105, the communication unit 22 modulates infrared light based on the power supply state information indicating “power supply OFF” and outputs it from the signal output unit 14 (step 112). ). Thereafter, the control unit 26 issues a sound pressure level measurement request to the ambient sound pressure measurement unit 24 and a time measurement request to the time measurement unit 23. The ambient sound pressure measurement unit 24 measures the sound pressure level of the ambient sound of the remote controller 1 and notifies the sound volume control unit 33 of the measurement result as ambient sound pressure level information (step 113). In addition, the time measuring unit 23 notifies the volume control unit 33 of the time as time information (step 114). Then, the volume control unit 33 reads the volume stored as the set volume information from the memory 25 (step 115). Thereafter, the read sound volume is additionally plotted in the “ambient sound pressure level-volume characteristic graph” of the memory 25 using the received ambient sound pressure level information and time information, and the sound volume setting table is updated as necessary (step). 116).

  Here, when the power of the broadcast receiving apparatus 2 is turned off, it is considered that the volume that the user felt most preferable in the environment is set in the broadcast receiving apparatus 2. Therefore, the remote controller 1 measures the ambient sound pressure level and time when the broadcast receiving apparatus 2 is turned off, and uses the measured ambient sound pressure level and time to set sound volume information ( The sound volume set in the broadcast receiver 2 when the power is turned off is plotted in the “ambient sound pressure level-volume characteristic graph”. Then, the volume setting table is updated as necessary. Thereby, the optimal volume in the environment (the surrounding sound pressure level and time) can be registered in the volume setting table of the remote controller 1.

  When the broadcast receiver 2 is turned on, the ambient sound pressure level is measured in the absence of sound output from the broadcast receiver 2 immediately before the power is turned on, and the measured ambient sound pressure level is measured. Is read from the memory 25 and set in the broadcast receiving apparatus 2. Thereby, the sound volume that the user feels most preferable in the environment can be set in the broadcast receiving apparatus 2.

  Next, an operation flow of the remote controller 1 when the user presses the channel selection button 12 of the remote controller 1 will be described with reference to FIG. 5, when any one of the channel selection buttons 12 is pressed by the user, the input unit 21 detects that the channel selection button 12 has been pressed (step 201), and the type of the channel selection button 12 that has been pressed. And “notify channel selection button” is notified to the channel control unit 32 of the control unit 26 (step 202). When the “channel selection button press” is notified, the channel control unit 32 notifies the communication unit 22 of the station number corresponding to the type of the pressed channel selection button as channel selection information (step 203). Further, the channel selection information stored in the memory 25 is updated to new channel selection information (step 204). The communication unit 22 modulates infrared light based on the received channel selection information, and outputs it from the signal output unit 14 (step 205).

  FIG. 6 shows an operation flow of the remote controller 1 when the user presses the volume button 13 of the remote controller 1. When the user presses the volume button 13a or the volume button 13b, the type of the volume button (the volume button 13a or the volume button 13b) pressed on the input unit 21 and the pressed time are recognized (step 301), and control is performed. The volume control unit 33 of the unit 26 is notified (step 302). The volume control unit 33 calculates the volume to be changed from the notified type of the volume button 13 and the pressed time (step 303). Furthermore, the volume control unit 33 reads the volume currently set in the broadcast receiving apparatus 2 stored as the set volume information in the memory 25, and newly sets it from the read volume and the calculated volume to be changed. The volume is obtained (step 304). Then, the newly set volume is notified to the communication unit 22 as set volume information (step 305), and updated by changing the set volume information stored in the memory 25 to the new set volume information (step 306). ). The communication unit 22 modulates infrared light based on the received set sound volume information and outputs it from the signal output unit 14 (step 307).

The volume setting table is associated with ambient sound pressure level information and time information, and the volume of the broadcast receiving apparatus 2 that the user feels most favorable in the environment at that time (ambient sound pressure level and time) is registered. . When the power of the broadcast receiving device 2 is turned on, the time and the surrounding sound pressure level are measured, and the corresponding sound volume is read from the volume setting table and set in the broadcast receiving device 2, whereby the broadcast receiving device 2 is set. In addition, it is possible to set the sound volume that the user feels most favorable in the environment.

  The above control method is not limited to setting a large volume in the broadcast receiving device 2 when ambient noise is large. For example, in the case of a user who prefers to reduce the volume of the broadcast receiving device 2 when the ambient sound is high, and to maintain a constant volume as a whole, if the ambient noise is high, the broadcast receiving device 2 is low. The volume may be set.

  Also, even when the surrounding volume is the same, by changing the volume set in the broadcast receiving apparatus 2 according to the time zone, for example, in a relatively quiet time zone such as early morning, a smaller volume can be compared during the day. It is possible to flexibly cope with the user's life by setting a larger volume in the broadcast receiving apparatus 2 during a time period when the loud noise is high.

In FIG. 8, the remote controller 1b detects that the user has pressed the power button 11 (step 401), and notifies the control unit 26 of “power button pressed” (step 402). When notified of “pressing the power button”, the control unit 26 reads and updates the power state information of the audio output device stored in the memory 25 (step 403). Then, the updated power supply state information is notified to the communication unit 22 (step 404).

  Next, the updated power supply state information is confirmed (step 405). If the power supply state information is “ON”, the control unit 26 issues a sound pressure level measurement request to the ambient sound pressure measurement unit 24. The ambient sound pressure measurement unit 24 measures the sound pressure level of the ambient sound of the remote controller 1b, and notifies the control unit 26 of the measurement result as ambient sound pressure level information (step 406). The control unit 26 refers to the volume setting table stored in the memory 25, reads the volume corresponding to the received ambient sound pressure level information, and notifies the communication unit 22 as the set volume information (step 407). The communication unit 22 modulates infrared rays based on the notified power supply state information (power supply ON) and set sound volume information, and outputs the modulated infrared signal as a control signal for the audio output device (step 408). On the other hand, if the updated power status information is “OFF” in step 405, the communication unit 22 modulates and outputs infrared light based on the power status information indicating “power OFF” (step 409).

The display unit 27 displays the user name of the received user information on the display 16 (step 505).

  Next, in FIG. 14, when the user presses the power button 11, the input unit 21 detects that the power button 11 has been pressed (step 601), and the power state monitoring unit 31 of the control unit 26 notifies the “power button”. Is pressed "(step 602). The power supply state monitoring unit 31 updates the power supply state information stored in the memory 25 (step 603), and notifies the communication unit 22 and the display unit 27 of the updated power supply state information (step 604).

  Next, when the updated power status information is “ON” (step 605), the ambient sound pressure measurement unit 24 acquires the ambient sound pressure level information and notifies the volume control unit 33 (step 606). Further, the time measuring unit 23 acquires time information and notifies the volume control unit 33 (step 607). The volume control unit 33 selects the volume setting table of the user using the remote control 1c from the memory 25 using the user information (step 608). Then, using the selected sound volume setting table, the sound volume corresponding to the ambient sound pressure level information and the time information is read and notified to the communication unit 22 and the display unit 27 as set sound volume information (step 609). Further, the set volume information stored in the memory 25 is updated by changing to the new set volume information (step 610). Further, the channel control unit 32 reads the channel selection information from the memory 25 and notifies the communication unit 22 and the display unit 27 (step 611). The communication unit 22 modulates infrared rays based on the power supply state information, the set sound volume information, and the channel selection information, and outputs the infrared rays from the signal output unit 14 (step 612). The display unit 27 displays user information, set volume information, and channel selection information on the display 16 (step 613).

  On the other hand, if the updated power supply state information is “OFF” in step 605, the communication unit 22 modulates infrared light based on the power supply state information indicating “power supply OFF” and outputs it from the signal output unit 14 (step 614). ). Further, the display unit 27 stops displaying the user information, the set sound volume information, and the channel selection information on the display 16 (step 615). Thereafter, the ambient sound pressure measurement unit 24 measures the sound pressure level of the ambient sound of the remote controller 1c, and notifies the sound volume control unit 33 as ambient sound pressure level information (step 616). In addition, the time measuring unit 23 notifies the volume control unit 33 of the time at that time as time information (step 617). The volume control unit 33 reads the volume stored as the set volume information from the memory 25 (step 618), and controls the remote controller 1c as necessary based on the read volume, the received ambient sound pressure level information, and time information. The volume setting table of the user being used is updated (step 619).

  In the third embodiment, the fingerprint sensor 15 is used as the user identification unit. However, the fingerprint sensor 15 is not limited to the fingerprint sensor as long as the user can be identified. For example, a voice input unit may be provided to perform voice print authentication. An image input unit may be provided to perform authentication using the user's pupil. In addition, a user switching button for switching a user who uses the remote control 1c can be arranged, and the user can be designated by the user himself / herself. In this case, it is preferable that a password or the like can be set as necessary.

  As described above, the remote controller 1c according to the third embodiment includes the fingerprint sensor 15 as the user identification unit and the volume setting table for each user. Therefore, the optimal volume for each user can be set in the broadcast receiving apparatus 2. In addition, since the volume can be registered in the volume setting table according to the time zone set by each user and the ambient sound pressure level range, a fine volume setting according to each user's lifestyle is performed. be able to.

  Furthermore, since the remote controller 1c according to the third embodiment includes the display unit 27, it is possible to check the volume and station number set in the broadcast receiving apparatus 2 and to check whether the user is correctly recognized. it can.
