  By the way, the purpose of a user using headphones or earphones is generally to avoid disturbing the surroundings. In this case, the influence of the sound can be prevented by muting the sound from the speaker. However, the influence of light on the surroundings is large in a large-screen television receiver.

  Also, when using headphones or earphones, the viewing distance is often shorter than usual due to short wiring. In this case, the screen may be too large for the field of view, making it difficult to see.

  It is an object of the present invention to provide a video / audio output device that reduces the influence of light on the surroundings when headphones or earphones are connected.

  In order to achieve the above object, an audio output device according to an aspect of the present invention includes a video output unit that outputs video displayed on a display unit, a connection unit to which an audio output destination device can be connected, and audio output. When the audio output unit that outputs audio to the destination device or to the speaker and the audio output destination device are connected to the connection unit, the audio output destination device is not connected to the connection unit. And a control unit that controls to reduce the output range of the display unit.

  According to this configuration, when an audio output destination device is connected to the connection unit, a portion (black portion) where nothing is displayed on the screen is generated by reducing the output range of the display unit. The light output by the image is reduced. Therefore, the influence of light on the surroundings can be reduced. This is effective in preventing surrounding sleeping people from being dazzled when viewed in a bedroom or the like. Also, in situations where the audio output destination device is used, the viewing distance is often shorter than normal due to reasons such as short wiring, in which case the display area of the display unit can be reduced to reduce the visual field. Can solve the situation where the screen is too large.

  In the above video / audio output device, for example, the output range may be reduced based on the output range control history. In this way, an appropriate image output range can be determined.

  The tuner 41 demodulates and digitizes the digital television broadcast signal received by the antenna 61. The data processing unit 42 separates video / audio data and control data received from the tuner 41 and the television receiver 20, conversely combines video / audio data and control data to be output, and decodes video data. . Further, the data processing unit 42 compresses and encodes the video / audio data in accordance with MPEG2 or the like, and the compressed video data reproduced by the HDD recording / reproducing unit or the BD (Blu-ray Disc) / DVD recording / reproducing unit. Or decompression decoding. The data processing unit 42 processes the input / output data by performing these processes.

  The HDD recording / reproducing unit 43 records the compressed video / audio data received from the data processing unit 42 on the HDD or reproduces the data recorded on the HDD. The BD / DVD recording / reproducing unit 44 records the compressed video / audio data received from the data processing unit 42 on the inserted BD or DVD, or reproduces the data recorded on the BD or DVD.

  The OSD unit 45 allows various setting values to be set while being displayed on a part of the display unit 26 of the television receiver 20. The audio output unit 46 analogizes the audio data from the data processing unit 42 and outputs the analog data to the phone terminal 47. The phone terminal 47 is a terminal to which an audio output destination device (headphone, earphone, etc.) is connected. Usually, the phone terminal on the device side of the audio output destination is a male terminal called a phone plug, and the phone terminal 47 on the HDD integrated optical disk device 40 side is a female terminal called a phone jack.

  The external I / F 51 includes an external input / output terminal to which the television receiver 20 is connected. The control unit 52 includes a microprocessor or the like, and controls each unit of the HDD integrated optical disk device 40.

  Next, the operation of the television system 10 when an audio output destination device is used will be described. Hereinafter, a case where headphones are used as the audio output destination device and the headphones are connected to the phone terminal 28 of the television receiver 20 will be described as an example.

  FIG. 3 is a flowchart showing the operation of the television receiver 20. FIG. 4 is a diagram showing an image output range 71 on the screen of the television receiver 20. For example, when a headphone is connected to the phone terminal 28 in a state where a digital television broadcast received by the antenna 60 is output to the display unit 26 and the speaker 27, the control unit 33 is connected to the phone terminal 28 in step S10. Is detected.

  Proceeding from step S10 to step S11, the control unit 33 reduces the image output range 71 of the display unit 26 more than when the headphones are not connected to the phone terminal 28 (for example, the state immediately before the connection). Control. As shown in FIG. 4, the image output range 71 is the part of the screen (the part where the pixels are arranged) 70 that actually displays the video (content), that is, the size of the video. This refers to a portion excluding a portion (black portion) 72 that is possible but not displaying anything. Therefore, reducing the image output range 71 means reducing the size of the actual video as shown in FIG.

  The output range 71 is controlled based on the control history of the output range 71. For example, when the output range 71 is reduced, the output range 71 may be the same as the previously reduced output range 71, or may be an average value of the past reduced output range 71, or may be a preset output range. The image range 71 may be used. The previously reduced output range 71 can be used by storing in the memory 29 the output range 71 when the output range 71 was last reduced. As the average value of the past reduced output range 71, for example, values obtained by reducing the last three output ranges 71 are stored in the memory 29, and the vertical and horizontal lengths and areas of these output ranges 71 are stored. Average values such as can be used. The preset output range 71 is the preset output range 71 set by the user from a menu screen or the like, and selects a reduction ratio (80%, 50%, 30%, etc.) with respect to the maximum output range 71. This is the size specified.

  When the output range 71 is reduced, the output position on the display unit 26 may be set to a preset position. For example, the user may be able to set from a menu screen or the like, or may be specified at the time of manufacture. The image output position may be the center, upper end center, lower end center, right end center, left end center, upper right, upper left, lower right, lower left, etc. of the screen. Further, the image output position may be moved to a desired position with an arrow key of the remote control 35 in a state where the image output range 71 is reduced.

  Proceeding from step S11 to step S12, the control unit 33 controls the luminance of the display unit 26 to be lower than when the headphones are not connected to the phone terminal 28 (for example, a state immediately before being connected). . This control is performed based on the luminance control history of the display unit 26.

  For example, when the luminance of the display unit 26 is lowered, the luminance can be made the same as the previously lowered luminance. The previously lowered brightness can be used by storing the brightness when the image output range 71 was last reduced in the memory 29.

  Moreover, when lowering | hanging the brightness | luminance of the display part 26, it is good also as an average value of the brightness | luminance reduced in the past, for example. As the average value of the previously lowered luminance, for example, values obtained by reducing the last three image output ranges 71 are stored in the memory 29, and the average value of the luminance can be used.

  Moreover, when making the brightness | luminance of the display part 26 low, it is good also as a preset brightness | luminance, for example. The brightness set in advance is a value set by the user in advance from the menu screen or the like, and is a ratio (80%, 80%, etc.) to the brightness when the output range 71 is not reduced (for example, a state immediately before the output range 71 is reduced). 50%, 30%, etc.) and so on.

  Further, when the luminance of the display unit 26 is lowered, for example, the luminance may be determined based on the current time. For example, since the surroundings are bright in the daytime and it becomes difficult to see if the brightness is too low, the brightness is slightly reduced (for example, 10% lower than the current level). On the other hand, at night, since the surroundings are dark and viewing is possible even when the luminance is lowered, the luminance is greatly reduced (for example, reduced by 50%).

  Further, when the luminance of the display unit 26 is lowered, for example, it may be lowered stepwise. For example, the luminance is gradually decreased in three steps every 10 seconds until the luminance is finally decreased. Note that the luminance may be lowered directly rather than stepwise until the luminance is finally reduced.

  If the television receiver 20 includes an illuminance sensor that detects ambient brightness, the luminance can be determined based on the detection value of the illuminance sensor when the luminance of the display unit 26 is lowered. For example, if the brightness is too low when the daytime or indoor lighting is on and the surroundings are bright, it is difficult to see if the brightness is too low, so the brightness is reduced slightly (for example, 10% lower than the current level). On the other hand, if the room lighting is turned off at night and the surroundings are dark, the user can view even if the luminance is lowered. Therefore, the luminance is greatly reduced (for example, reduced by 50%).

  Proceeding from step S12 to step S13, the control unit 33 controls the speaker 27 to be muted. Then, it progresses to step S14 and the control part 33 is controlled to adjust the sound volume output to a headphone. Specifically, the volume for the speaker 27 is adjusted to the volume for the headphones. For example, the current volume is reduced (for example, reduced by 20%). Thereafter, the process proceeds from step S14 to step S15, and the control unit 33 performs control so as to output the sound to the headphones.

  In this way, when headphones are connected to the phone terminal 28, a portion (black portion) 72 where nothing is displayed on the screen is generated by reducing the image output range 71 of the display unit 26. The light output is reduced (see FIG. 4). Therefore, the influence of light on the surroundings can be reduced. This is effective in preventing surrounding sleeping people from being dazzled when viewed in a bedroom or the like. Also, in the situation where headphones are used, the viewing distance is often shorter than usual due to reasons such as short wiring, and in that case, by reducing the image output range 71 of the display unit 26, The state that is too large can be solved.

  Further, when headphones are connected to the phone terminal 28, the influence of light on the surroundings can be further reduced by reducing the luminance of the display unit 26. In addition, when headphones are connected to the phone terminal 28, the influence of sound on the surroundings can be eliminated by muting the speaker 27. In addition, when headphones are connected to the phone terminal 28, by adjusting the volume output to the headphones, the user does not need to manually adjust the volume and can use the headphones comfortably.

  Steps S12, S13, and S14 are not essential, and any one or more steps may be omitted.

  Next, a case where the headphones are disconnected from the phone terminal 28 will be described. FIG. 5 is a flowchart showing the operation of the television receiver 20. Here, FIG. 5 will be described as continuing from step S15 of FIG.

  Regardless of whether or not the user intends, when the headphones are disconnected from the phone terminal 28, the control unit 33 detects that the phone 33 is not connected to the phone terminal 28 in step S20. Proceeding from step S20 to step S21, the control unit 33 determines whether or not the headphones are connected to the phone terminal 28 again.

  If the headphones are connected again in step S21, the process returns to step S20. That is, the state when the headphones are connected is maintained. On the other hand, if the headphones are not connected again in step S21, the process proceeds to step S22, and the control unit 33 determines whether or not a predetermined time has passed since the headphones were removed. The predetermined time may be set by the user from a menu screen or the like, or may be specified at the time of manufacture. Note that the predetermined time is preferably equal to or longer than the time required for reconnection when the headphones are unintentionally disconnected by the user, and can be, for example, 10 seconds.

  If the predetermined time has not elapsed in step S22, the process returns to step S21. On the other hand, when the predetermined time has elapsed in step S22, the process proceeds to step S23, and the control unit 33 performs control so that the headphones are returned to the state where the headphones are not connected to the phone terminal 28 (for example, the state immediately before being connected). In other words, the image output range 71 and the brightness of the display unit 26 are returned to the state where the headphones are not connected, and the sound is output from the speaker 27 at the volume level when the headphones are not connected.

  In addition, when returning the brightness | luminance of the display part 26 in step S23, you may make it high in steps, for example. For example, the luminance is gradually increased in three steps every 10 seconds until the luminance is finally increased. Note that the luminance may be increased directly rather than stepwise until the luminance that is finally increased.

  In addition, if the headphones include a wearing detection sensor that detects the wearing state of the ear, the detection result of the wearing sensor may be used. That is, the determination in step S20 may be a case where it is detected that the mounting detection sensor has been removed from the ear, and the determination in step S21 may be a case where it is detected that the mounting detection sensor has been mounted on the ear again. Such a wearing detection sensor is particularly effective when the headphones are wirelessly connected.

  Thus, when the headphones are disconnected from the phone terminal 28, the current video / audio output state is maintained without immediately returning to the state where the headphones are not connected. Thereby, when a headphone removes unintentionally by a user, it can prevent returning to the state where it is not connected until it connects again. Therefore, even if the user unintentionally disconnects the headphones, the user can quickly connect the headphones without causing trouble to the surroundings.

  Instead of the processing in step S22, an OSD is output so that the user can select whether or not to return to a state in which headphones are not connected (for example, a state immediately before being connected), and according to the user's selection result You may make it process.

  In addition to the above embodiment, the same effect can be obtained when the headphones are connected to the phone terminal 47 of the HDD-integrated optical disk device 40. For example, this is a case where the HDD-integrated optical disk device 40 performs an operation in accordance with the operation of the television receiver 20 described above in accordance with the insertion and removal of headphones. In this case, the present invention can be applied not only during reception of a television broadcast but also during playback of content.

  It should be noted that the same operation and effect can be obtained with the above-described television receiver 20 alone, to which the HDD integrated optical disk device 40 is not connected. Further, the same effect can be obtained by combining the HDD integrated optical disk device 40 and another television receiver.

  If the connection status of the phone terminal 28 can be transmitted from the television receiver 20 to the HDD-integrated optical disk device 40, the above-described operation can be executed. For example, when both are connected via HDMI, the HDD-integrated optical disc apparatus 40 can perform the above-described operation even when headphones are inserted into or removed from the phone terminal 28 of the television receiver 20.

  Next, an operation applicable to a video / audio output device provided with a playback unit (HDD recording / playback unit 43 or BD / DVD recording / playback unit 44 in FIG. 2) that plays back video and audio recorded on a recording medium. Will be described. This apparatus also includes an apparatus having a so-called chasing playback function for outputting a program being broadcast while recording it for a certain period of time. In the following, a case where headphones are used as the audio output destination device and the headphones are connected to the phone terminal 47 of the HDD-integrated optical disc apparatus 40 will be described as an example.

  When a headphone is connected to the phone terminal 47 in a state where the content reproduced by the HDD recording / reproducing unit 43 or the BD / DVD recording / reproducing unit 44 is output to the display unit 26 and the speaker 27, the HDD integrated optical disk device 40 executes the same processing as in FIG. A case where the headphones are disconnected from the phone terminal 47 will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the HDD-integrated optical disk device 40, which is the operation following step S15 when the HDD-integrated optical disk device 40 executes the same processing as that in FIG.

  Regardless of whether or not the user intends, when the headphones are disconnected from the phone terminal 47, the control unit 52 detects that the headphones 52 are not connected to the phone terminal 47 in step S30. Proceeding from step S30 to step S31, the control unit 52 controls to stop the reproduction of the content.

  Proceeding from step S31 to step S32, the controller 52 determines whether or not the headphones are connected to the phone terminal 47 again. When the headphones are connected again in step S32, the process proceeds to step S33, and the reproduction is resumed from the position where the headphones are stopped while maintaining the state when the headphones are connected. On the other hand, if the headphones are not connected again in step S32, the process proceeds to step S34, and the control unit 52 determines whether or not a set time has passed since the headphones were removed. The set time may be set by the user from a menu screen or the like, or may be specified at the time of manufacture. Note that the set time is preferably equal to or longer than the time required for reconnection when the headphones are unintentionally disconnected by the user, and can be, for example, 10 seconds.

  If the set time has not elapsed in step S34, the process returns to step S32. On the other hand, when the set time has elapsed in step S34, the process proceeds to step S35, and the control unit 52 returns to the state where the headphones are not connected to the phone terminal 47 (for example, the state immediately before being connected) while the reproduction is stopped. To control. In other words, the image output range 71 and the luminance of the display unit 26 are returned to the state where the headphones are not connected, and the sound is output from the speaker 27 at the volume level when the headphones are not connected. The content output at this time can be, for example, the channel selected last.

  In addition, if the headphones include a wearing detection sensor that detects the wearing state of the ear, the detection result of the wearing sensor may be used. That is, the determination in step S30 may be a case where it is detected that the mounting detection sensor has been removed from the ear, and the determination in step S32 may be a case where it is detected that the mounting detection sensor has been mounted on the ear again.

  As described above, when the headphones are disconnected from the phone terminal 47, the playback is stopped, so that the user does not need to manually stop the playback when the headphones are unintentionally disconnected. In addition, even when the user unintentionally disconnects the headphones, the playback is resumed from the position where the headphones were stopped by quickly connecting the headphones, so that the user can quickly watch and continue using it.

  In step S35, the user may be allowed to select whether to stop the reproduction or to resume the reproduction. Further, it may be possible to set in advance whether playback is to be stopped or restarted from the menu screen or the like.
