Description

The present invention relates to a disc device built-in television receiver in which a disc device control means for playing a music disc and a control device for a television receiver having a sleep timer function are connected by bus communication. The present invention relates to a disk device built-in type television receiver having a break timer function using reproduction of a music disk by a disk device.

  Some conventional television receivers have a so-called rest timer function. This rest timer function is basically to prevent the viewer from forgetting to turn off the power. When the rest timer is set, the video is displayed on the TV until a predetermined timer time elapses. While displaying on the screen and outputting sound from an internal speaker, the power is automatically turned off when the timer time elapses, and the output of video and sound is stopped. When the sleep timer is set, the TV screen display is turned off and only the sound is output from the internal speaker. When the timer time elapses, the power is automatically turned off and the sound output is stopped ( For example, see Patent Document 1).

  Further, in the above-mentioned Patent Document 1, a device is devised when the viewer makes a TV viewing request after the rest timer is set and before the time of the rest timer elapses. That is, when a TV screen is displayed in response to a viewer's viewing request, the TV screen is initially displayed darker as the video turn-off time is longer so that the brightness is suitable for the viewer's eyes. It is brightened and finally returned to the original brightness. Thereby, it is possible to redisplay the TV screen which is kind to the viewer's eyes.

On the other hand, with regard to audio output, for example, Patent Document 2 describes that a fade-out operation is performed in which a specific volume is set during operation of the sound source circuit and the volume is reduced as the operation ends, and this fade-out operation is performed. It is described that it can be used as a so-called rest timer that sleeps while listening to the sound of an acoustic device.

  The television receiver disclosed in Patent Document 1 discloses a technique in which when a viewer makes a TV viewing request, the TV screen is displayed dark at first and then gradually brightened. However, nothing has been devised about the TV screen display during sleep, which is the original function of the sleep timer, and the TV screen disappears suddenly when the timer time elapses, or the TV screen from the beginning when the sleep timer is set Was to erase.

  In addition, as described in Patent Document 2 above, volume control with a sleep timer can be smoothly introduced into a sleep state by performing a fade-out operation that reduces the volume as the operation ends. Is possible.

  However, Patent Document 2 also does not propose any specific control method such as how to reduce the volume control. Also, since the time until sleep varies depending on the person and the physical condition of the day, it is necessary to prepare a plurality of timer times such as 30 minutes or 60 minutes as the timer time of the rest timer. In this case, the control for lowering the sound volume varies depending on the timer time, but nothing is described in Patent Documents 1 and 2 for individual control corresponding to the timer time. In other words, the above-mentioned Patent Documents 1 and 2 have a problem that the holiday timer function cannot be finely controlled in accordance with the viewer. Therefore, it was not always good for viewers. For example, when the sleep timer is set while listening at a low volume originally, if the initial setting volume of the sleep timer is higher than the volume that was listened to before, the volume at the time when the sleep timer was set On the contrary, there is a possibility that a problem such as will become larger.

  The present invention was devised to solve such problems, and its purpose is to consider the convenience of the viewer by finely controlling the brightness and volume control of the TV display screen when setting the sleep timer. Another object of the present invention is to provide a disc apparatus built-in television receiver.

In order to solve the above-described problems, a disk device built-in television receiver according to the present invention includes a disk-side control means for a disk device for playing a music disk, and a television-side control means for a television receiver having a sleep timer function. In the television receiver with built-in disk device connected by bus communication, when the user selects the sleep timer mode and sets the timer time, the television-side control means sets the sleep timer setting code to the timer The disc side control means adjusts the brightness of the monitor screen to a predetermined constant brightness when receiving the sleep timer setting code and the timer time. In addition, the volume of the music disc being played by the disc device is preset. In order to play the music disc, the auto-repeat playback is started from this point until the end of the timer time, and the TV-side control means responds to the timer time. The basic configuration is that the brightness of the monitor screen is gradually reduced from the constant brightness, and the reproduction volume is gradually decreased from the constant volume.

According to such a configuration , when the user selects the sleep timer mode, the disc-side control means adjusts the brightness by reducing the brightness by a predetermined level so that the brightness of the monitor screen becomes a predetermined constant brightness. At the same time, the volume of the music disk being played by the disk device is adjusted to a predetermined level so that the volume is a predetermined volume.

  Here, reducing the brightness of the monitor screen to a predetermined level means, for example, that when the monitor screen is a black screen and a logo mark such as a play mark is displayed there, the logo mark appears to be thin relative to the black screen. It means to reduce to the brightness (brightness). In addition, decreasing the sound volume by a predetermined level means that the sound volume is decreased to a level that does not disturb the user when the user closes his eyes and starts sleeping.

  Then, from this fixed level, the monitor screen is gradually dimmed according to the set timer time, and the playback volume is gradually lowered to introduce the user into the sleep state comfortably. Is possible.

  In this case, the fixed volume may be a playback volume of a music disk being played by the disk device when the sleep timer mode is selected. That is, it is possible to shift to the sleep timer mode while maintaining the reproduction volume when the sleep timer mode is selected. Thus, by setting the playback volume to the same volume before and after the transition from the normal playback to the rest timer mode, it is possible to smoothly transition from the normal playback state to the rest timer mode.

  In addition, the fixed sound volume may be a mode setting sound volume set in advance in correspondence with the sleep timer mode. That is, it may be preset as a fixed value.

  Further, the fixed volume may be a user set volume set by a user. That is, the volume is set individually by the user. In this way, by allowing the user to set freely, individual volume setting for each user can be performed, which is more convenient for the user.

  Furthermore, the fixed volume may be an initial set volume of a television receiver. Usually, various conditions are initially set for a television receiver or the like at the time of shipment from the factory, and the volume when the power of the television receiver is turned on is also initialized. Therefore, by using this initial setting value, there is no need to separately set a constant volume used in the sleep timer mode.

  Further, according to the present invention, a plurality of timer times that can be set by a user are prepared, and the fixed volume is set to one fixed value regardless of the plurality of timer times, and from this fixed value, In the case where a plurality of volume reduction patterns set to gradually decrease the volume according to the plurality of timer times are stored, in the rest timer mode, the disc-side control means responds to the timer time. The playback volume may be gradually reduced from the fixed value in accordance with an individual volume reduction pattern.

  In this way, by configuring the playback volume to gradually decrease from a fixed value according to the individual volume reduction pattern corresponding to the timer time, even if the timer time set by the user differs, the timer time has elapsed Since the playback volume can be reduced to almost zero immediately before the operation, even if the power is turned off thereafter, the operation of the device can be stopped in a state that the user hardly understands (that is, without disturbing sleep). It becomes possible.

  Further, according to the present invention, a plurality of timer times that can be set by a user are prepared, the fixed volume is set as an individual fixed value for each of the plurality of timer times, and the plurality of timer times In the case of storing one volume lowering pattern that gradually lowers the volume at the same level regardless of whether the disc-side control means is set to an individual fixed value according to the timer time in the sleep timer mode. The playback volume may be gradually reduced according to the one volume reduction pattern.

  In this way, only one volume reduction pattern is used regardless of the timer time, and instead, a fixed volume at the start of the rest timer mode is individually set according to the timer time. Specifically, the constant sound volume for 60 minutes is set higher than the constant sound volume for the timer time of 30 minutes. As a result, the control by the disc-side control means can be made simple control according to one volume reduction pattern, and the playback volume can be reduced to almost zero immediately before the timer time elapses. Thereafter, even if the power is turned off, the operation of the device can be stopped in a state that the user hardly understands (that is, without disturbing sleep).

  Further, according to the present invention, a plurality of timer times that can be set by the user are prepared, and the fixed volume is set as an individual fixed value for each of the plurality of timer times, and these individual fixed values are set. When a plurality of volume reduction patterns set to gradually decrease the volume according to the plurality of timer times are stored, the disc-side control means responds to the timer time in the rest timer mode. Alternatively, the playback volume may be gradually reduced from an individual fixed value according to an individual volume reduction pattern corresponding to the timer time.

  In this way, according to the individual volume reduction pattern according to the timer time, by configuring the playback volume to gradually decrease from the individually set fixed value, even if the timer time set by the user is different, Just before the timer expires, the playback volume can be reduced to almost zero, so that even if the power is turned off after that, the device operates in a state that is hardly noticeable to the user (ie, without disturbing sleep) Can be stopped.

  Further, according to the present invention, a plurality of timer times that can be set by a user are prepared, the fixed volume is set to a fixed value regardless of the plurality of timer times, and the plurality of timers In the case of storing one volume lowering pattern for gradually lowering the volume at the same level regardless of time, in the sleep timer mode, the disk side control means does not change the one fixed time regardless of the timer time. The playback volume may be gradually lowered from the value according to the one volume reduction pattern, and the music playback may be stopped at the end of the timer time regardless of the playback volume level at that time.

  In this way, by using only one constant volume at the start of the sleep timer mode and only one volume reduction pattern, control of the break timer mode in the disk side control means is extremely simple control. It can be. In this case, for example, when the timer time is set to 30 minutes and the timer time is set to 30 minutes, for example, when a volume reduction pattern is stored such that the playback sound volume is reduced to almost zero immediately before the timer time elapses. Even before the end of the timer time, the music disc is still being played at a certain volume, and the power is suddenly turned off from that volume. However, since this playback volume is a volume that is further lowered by a predetermined level from the fixed volume that was originally set to be low, even if the playback sound suddenly stops, it may be of concern to the user who has gone to sleep. It is not an environmental change and does not interfere with sleep.

  According to the present invention, at the time of transition to the sleep timer mode, the disc-side control means sets the playback volume level when the fixed value is higher than the playback volume level of the music disc at that time. The sleep timer mode may be started in a maintained state, and when the playback volume level matches the level of the volume reduction pattern, the playback volume may be gradually decreased according to the volume reduction pattern thereafter.

  That is, depending on the viewing situation of the user (for example, when the child is sleeping in the next room and the surrounding environment is also viewed at a quiet midnight), the user originally has the TV at a low volume. It is normal to watch. In such a viewing situation, a certain volume level set corresponding to the sleep timer mode may be higher than the viewing volume level. In this situation, when the user sets a sleep timer, a situation occurs in which the sound volume is slightly increased. Therefore, if configured as in the above invention, even if the sleep timer mode is set, the playback volume remains the same as the previous viewing volume, so that the problem that the volume increases unexpectedly is prevented. It becomes possible.

  In each of the above configurations, the disc-side control means plays the music disc in order from the beginning if the music disc loaded in the disc device is not being played when the sleep timer mode is selected, It may be configured to perform normal auto-repeat playback or random auto-repeat playback that repeats playback after returning to the beginning. Further, the disc-side control means, when the music disc loaded in the disc device is not being played when the sleep timer mode is selected, and when the program playback is set by the user, You may comprise so that auto repeat reproduction may be performed according to program reproduction. In any case, by performing auto-repeat playback, it is possible to continue playing the music disk until the end of the timer time regardless of the timer time set by the user. In this case, if a user's favorite music disc is loaded, only the user's favorite music is played repeatedly, so that the user's favorite music can be set as BGM and a comfortable sleep can be achieved.

  According to the television receiver with a built-in disk device of the present invention, since the break timer mode can be set using the playback volume of the music disk loaded in the disk device, the user's favorite music can be set in advance. If a recorded music disc is loaded, a rest timer mode can be set according to the user's preference. That is, the conventional break timer function of the television receiver alone uses the music of the program broadcast when the break timer mode is set, and may not necessarily match the user's preference. According to the television receiver with a built-in disk device of the present invention, since it is possible to set the rest timer mode using music according to the user's preference, it is extremely convenient for the user.

  Further, according to the television receiver with a built-in disk device of the present invention, when the user selects the sleep timer mode, the brightness is set to a predetermined level so that the brightness of the monitor screen becomes a predetermined constant brightness. The volume of the music disc being played by the disk device is adjusted to a predetermined level so as to be a predetermined volume, and from this fixed level, according to the set timer time, By gradually reducing the brightness of the monitor screen and gradually lowering the playback volume, the user can be comfortably introduced into the sleep state.

  Also, if the constant volume is the playback volume of the music disc being played by the disc device when the sleep timer mode is selected, the playback volume is the same volume before and after the transition from normal playback to the sleep timer mode. It is possible to make a smooth transition from the normal playback state to the sleep timer mode. Furthermore, if the fixed volume can be arbitrarily set by the user, individual volume setting for each user can be performed, which is more convenient for the user.

  Further, according to the television receiver with a built-in disk device of the present invention, the playback volume is gradually decreased from a fixed value according to an individual volume reduction pattern corresponding to the timer time, so that the user setting can be made. Even if the timer time is different, the playback volume can be reduced to almost zero just before the timer time elapses. It is possible to stop the operation of the device (without interruption).

  Further, according to the television receiver with built-in disk device of the present invention, there is only one volume reduction pattern regardless of the timer time, and instead, a constant volume at the start of the rest timer mode is set according to the timer time. With the configuration set individually, the control by the disc-side control means can be simplified according to one volume reduction pattern, and the playback volume is almost reduced immediately before the timer time elapses. Since it can be lowered to zero, even if the power is turned off after that, it is possible to stop the operation of the device in a state that the user hardly understands (that is, without disturbing sleep).

  In addition, according to the television receiver with built-in disk device of the present invention, the playback volume is gradually reduced from the fixed value set individually according to the individual volume reduction pattern corresponding to the timer time. Even if the timer time set by the user is different, the playback volume can be reduced to almost zero immediately before the timer time elapses. It is possible to stop the operation of the device (that is, without disturbing sleep).

  Further, according to the television receiver with built-in disk device of the present invention, in the rest timer mode, the playback volume is gradually lowered from one fixed value according to one volume reduction pattern regardless of the timer time, and the timer time At the end of, music playback may be stopped regardless of the playback volume level at that time. In this way, by using only one constant volume at the start of the sleep timer mode and only one volume reduction pattern, control of the break timer mode in the disk side control means is extremely simple control. It can be.

  Further, according to the television receiver with built-in disk device of the present invention, when the shift to the rest timer mode is performed, if the fixed value is higher than the playback volume level of the music disk at that time, the playback volume level The sleep timer mode may be started in a state where the playback volume is maintained, and when the playback volume level matches the level of the volume reduction pattern, the playback volume may be gradually decreased according to the volume reduction pattern thereafter. . As a result, even if the sleep timer mode is set, the playback volume is maintained as it is at the previous viewing volume, so that it is possible to prevent a problem that the volume increases unexpectedly.

The music disc in the present invention includes not only music CDs and music DVDs created in accordance with the CDDA (Compact Disc Digital Audio) standard, but also MPEG3 format, WMA (Windows (registered trademark) Media Audio). This includes discs on which music is recorded in a format. That is, it is a concept that includes all discs that can record and reproduce music in a predetermined format.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a functional block diagram showing an electrical configuration of a main part of a television set with a built-in disk device (for example, DVD device) according to the present embodiment. However, in the present embodiment, the disc playback processing by the DVD device and the video and audio signal processing by the television receiver are conventionally known processing, so here they are simply referred to as a disc signal processing unit and a TV signal processing unit, respectively. It is shown by a functional block.

  That is, in the television receiver with built-in disk device of the present embodiment, the disk control system 10 for playing the music disk 13 and the TV control system 20 having a break timer function that can be set by the user function in one housing. A disk-side microcomputer (disk-side control means) 11 that controls the entire disk control system 10, and a TV-side microcomputer (television-side control means) 21 that controls the TV control system 20 as a whole. Are connected bidirectionally by bus communication 35.

  The disc-side microcomputer 11 controls a disc signal processing unit 12 that performs a discrimination process for discriminating the type of the music disc 13 loaded in the main body and a reproduction process corresponding to the disc type. In addition, the disk signal processing unit 12 includes an OSD circuit 12a for displaying various setting screens including a setup screen for performing various settings on the disk device side.

  On the other hand, the output of the tuner circuit 22 that receives the television signal is connected to the TV signal processing unit 24 via the input switching circuit 23 that performs input switching with the disc generation signal from the disc signal processing unit 12. The output of the signal processing unit 24 is connected to a display unit 25 such as a CRT. The output of the input switching circuit 23 is connected to the internal speaker 27 via the amplifier 26. Further, the TV signal processing unit 24 includes an OSD circuit 24a for displaying various setting screens including a setup screen for performing various settings on the television receiver side.

  The TV-side microcomputer 21 decodes the television signal received via the tuner circuit 22 into a video signal and an audio signal, displays the video signal on the display unit 25 and outputs the audio signal from the internal speaker 27. 24 is controlled.

In addition, the TV-side microcomputer 21 has a display screen brightness system setting value set in advance at the time of shipment from the factory (that is, setting values such as brightness, contrast, color, sharpness, and tint) and the first power-on after shipment. A data storage unit 29 comprising an EEPROM or the like for storing the sound volume and the like as initial values is connected. The TV side microcomputer 21 is connected to a timer circuit 31 that measures the timer time set in the sleep timer mode. Furthermore, the TV side microcomputer 21 is connected to the output of a receiving unit 28 that receives various operation signals from the remote controller 41. The TV side microcomputer 21 controls the operation of the disk control system 10 and the TV control system 20 based on various operation signals transmitted from the remote controller 41. That is, in this embodiment, all control signals including power on / off of the disk control system 10 are transmitted to the disk side microcomputer 11 through the TV side microcomputer 21.

Further, in the television receiver with built-in disk device of this embodiment, three types of timer times that can be set by the user are prepared, for example, 30 minutes, 60 minutes, and 90 minutes, and according to these three types of timer times. A memory unit 30 that stores one or a plurality of volume reduction patterns set to gradually decrease the volume is provided. The memory unit 30 is connected to a bus communication 35 line. That is, direct access is possible from both the disk-side microcomputer 11 and the TV-side microcomputer 21. As the memory unit 30, an EEPROM, a flash memory, or the like can be used. Further, the memory unit 30 and the data storage unit 29 can be used in common, but in the present embodiment, the memory unit 30 and the data storage unit 29 are provided separately.

  Next, in the disk device built-in type television receiver having the above-described configuration, the TV-side microcomputer 21 and the disk-side microcomputer when the user selects the sleep timer mode using the remote controller 41 and sets an arbitrary timer time. 11 will be described with reference to the operation sequence diagram shown in FIG.

  When the user operates a vacation timer mode selection button (not shown) on the remote controller 41, a vacation timer code is transmitted from the remote controller 41 to the receiving unit 28 of the TV side microcomputer 21 (S1). The TV-side microcomputer 21 receives this vacation timer code, activates the OSD circuit 24a of the TV signal processing unit 24, and displays the setting screen 51 for the rest timer mode on the display unit 25.

  The user selects or inputs necessary items from this setting screen. Specifically, a rest timer time (for example, 30 minutes) is selected or input. Thereafter, when the user operates an “OK” button (not shown) on the sleep timer mode setting screen 51, the TV-side microcomputer stores the information on the sleep timer mode in an internal memory (not shown) and also sets a sleep timer confirmation code. Is transmitted to the disk-side microcomputer 11 via the bus communication 35.

  When the disc-side microcomputer 11 receives the rest timer confirmation code, it checks whether or not the music disc 13 is currently being reproduced by the disc device (S3). As a result, if the music disk 13 is being played back, auto repeat playback is set from this point until the end of the set timer time (S4).

  Also, the disk-side microcomputer 11 has a predetermined brightness (which will be described later) so that the screen brightness of the display unit 25 is set to be a screen suitable for listening as a BGM before going to bed. The playback volume of the music disc 13 was adjusted to a predetermined preset volume (which will be described later) so that the volume is suitable for listening as BGM before going to bed. After (S5), an adjustment completion code is transmitted to the TV side microcomputer 21 (S6).

  When receiving the adjustment completion code, the TV-side microcomputer 21 starts from the constant brightness and the constant volume set by the disk-side microcomputer 11 and starts the set rest timer mode. That is, for the reproduction of the music disc 13, auto repeat reproduction (which will be described later in detail) is performed from this point to the end of the timer time, and the reproduction volume is changed from a constant volume according to the volume reduction pattern shown in FIG. Decrease gradually. Similarly, the brightness of the screen of the display unit 25 is gradually decreased from a certain brightness (S7). In this case, the playback volume is controlled by the disk-side microcomputer 11, and the brightness of the screen of the display unit 25 is controlled by the TV-side microcomputer 21.

  As a result, near the end of the timer time, the volume level decreases to a level that is almost zero, and the brightness of the screen also decreases to a level that makes the room almost invisible. When the timer time elapses in this state, the TV-side microcomputer 21 transmits a power-off code to the disk-side microcomputer 11 (S8), and then turns off the power of the television receiver. On the other hand, when the disk-side microcomputer 11 also receives the power-off code, it turns off the power of the disk device. As a result, the processing in the rest timer mode ends.

  It should be noted that while the sleep timer mode is executed and the screen brightness and playback volume are gradually decreased from a certain brightness and a certain volume, the user cancels the sleep timer mode (not shown) of the remote control 41. When the button is operated, a cancel code for the sleep timer mode is transmitted from the remote controller 41 to the receiving unit 28 of the TV-side microcomputer 21. When the TV-side microcomputer 21 receives the cancel code for the sleep timer mode, the brightness of the screen is returned to the original brightness, and the disk-side microcomputer 11 is also based on the cancel code transmitted from the TV-side microcomputer 21. Thus, the playback volume of the music disk 13 is returned to the original volume, and the disk playback is canceled by returning to the playback state before setting the sleep timer mode.

  In the above-mentioned rest timer mode execution process, the screen brightness of the display unit 25 is adjusted to a constant brightness that is reduced by a predetermined level so as to obtain a screen and volume suitable for listening as BGM before going to bed, The playback volume of the music disc 13 is adjusted to a constant volume that is reduced by a predetermined level.

  Here, adjusting the brightness of the screen of the display unit 25 to a constant brightness by reducing a predetermined level is, for example, when displaying a logo mark such as a reproduction mark on the screen of the display unit 25 as a black screen. This means that the brightness is reduced to such a level that the logo mark appears thin on the black screen. Further, adjusting the playback volume to a certain level by reducing a predetermined level means that the volume is reduced to a level that does not disturb the user when the user closes his eyes and starts sleeping.

  Here, various levels can be set for a certain volume. Specifically, the playback volume of the music disk 13 being played back by the disk device when the sleep timer mode is selected may be used as the constant volume. That is, it is possible to shift to the sleep timer mode while maintaining the reproduction volume when the sleep timer mode is selected. Thus, by setting the playback volume to the same volume before and after the transition from the normal playback to the rest timer mode, it is possible to smoothly transition from the normal playback state to the rest timer mode.

  Moreover, it is good also as a mode setting volume preset as a fixed volume corresponding to the sleep timer mode. That is, it may be preset as a fixed value.

  Furthermore, the user-set volume set by the user may be used as the constant volume. That is, it can be set individually by the user. In this way, by allowing the user to set freely, individual volume setting for each user can be performed, which is more convenient for the user.

  Furthermore, it is good also as an initial setting volume of a television receiver as a fixed volume. Normally, various conditions are initially set for the television receiver and the like at the time of factory shipment, and the volume at the first power-on after the television receiver is shipped is also initialized and stored in the data storage unit 29. Stored. Therefore, this initial setting value may be used.

In the above operation sequence, various rest timer modes can be executed depending on how the volume reduction pattern is set. Next, reference examples and various examples of the volume reduction pattern will be described.

[Reference example]
In the reference example , when the sleep timer mode is set, the volume of the music disk 13 being played by the disk device is lowered to a certain volume. The certain volume at that time is reduced to the type of timer time (in this example, This is an embodiment in which one fixed value L11 is set regardless of (30 minutes, 60 minutes, 90 minutes).

FIG. 3 shows a configuration example of a volume reduction pattern of a reference example used at the time of the rest timer mode execution process.

  In this volume reduction pattern, the volume level at the start of the sleep timer mode is set to the same constant volume level (fixed value) L11 for the three types of timer times 30 minutes, 60 minutes, and 90 minutes, and from this fixed value L11. , There are three types of volume-decreasing patterns with different levels for decreasing the volume according to each timer time of 30 minutes, 60 minutes, and 90 minutes. That is, the level for lowering the volume is set to be larger as the timer time is shorter. However, in FIG. 3A, the change in volume is shown linearly, and the volume is lowered linearly, but the change in volume need not be linear, and may be changed in stages. . For example, when changing in 10 steps as shown in FIG. 3B, if the timer time is 30 minutes, every 3 minutes, if the timer time is 60 minutes, every 6 minutes, if the timer time is 90 minutes, it is 9 minutes. Every minute, the same predetermined level is lowered, and the volume may be set to zero as much as possible at the 10th stage.

[Example 1]
In the first embodiment, when the sleep timer mode is set, the volume of the music disk 13 being played by the disk device is lowered to a certain volume, and the certain volume at that time is reduced to the type of timer time (this example In this embodiment, the fixed values L21, L22, and L23 are set every 30 minutes, 60 minutes, and 90 minutes.

FIG. 4 shows an example of the configuration of the volume reduction pattern of the first embodiment used during the sleep timer mode execution process.

  In this volume reduction pattern, for the three types of timer times of 30 minutes, 60 minutes, and 90 minutes, the volume levels at the start of the sleep timer mode are set to constant volume levels (fixed values) L21, L22, and L23, respectively. From the fixed values L21, L22, and L23, the volume is set to gradually decrease at the same level regardless of each timer time. That is, the three volume reduction patterns corresponding to each timer time are straight lines parallel to each other. That is, by adjusting the volume levels of the fixed values L21, L22, and L23 in advance, the playback volume is set to almost zero level at the end of the timer time. However, in FIG. 4A, the change in volume is shown linearly, and the volume is lowered linearly, but the change in volume need not be linear, and may be changed in stages. . For example, as shown in FIG. 4 (b), if the timer time is 30 minutes, 5 steps every 6 minutes, if the timer time is 60 minutes, 10 steps every 6 minutes, if the timer time is 90 minutes, every 6 minutes The number of stages may be set to be lowered by the same predetermined level by varying the number of stages according to each timer time, such as 15 stages.

[Example 2]
The second embodiment, when setting rest timer mode, although lowering the specified volume with the volume of the music disc 13 being played by the disk apparatus, a constant volume at that time, the type of timer time (this Example Are set as individual fixed values L31, L32, and L33 every 30 minutes, 60 minutes, and 90 minutes), and a level for lowering the volume according to each timer time is set from these individual fixed values L31, L32, and L33. This is an example of three different volume reduction patterns.

FIG. 5 shows a configuration example of a volume reduction pattern according to the second embodiment that is used during the above-described rest timer mode execution process.

As can be seen from FIG. 5, the volume reduction pattern of the second embodiment is a combination of the pattern of the reference example and the pattern of the first embodiment. That is, the fixed values L31, L32, and L33 are set so as not to make a great difference, and the fixed value L33 is set not to be too high. As a result, the inclination angle of each volume reduction pattern is also set so as not to be as high as in the first embodiment. Also in the third embodiment, the change in volume is shown linearly in FIG. 5 and the volume is lowered linearly. However, the change in volume need not be linear, and the reference example and As in the case of the first embodiment, it may be changed stepwise.

[Example 3]
In the third embodiment, when the sleep timer mode is set, the volume of the music disc 13 being played by the disk device is lowered to a certain volume. The certain volume at that time is set to the type of timer time (this example In this embodiment, one fixed value L43 is set regardless of 30 minutes, 60 minutes, and 90 minutes, and the volume is gradually decreased from the one fixed value at the same level regardless of the timer time.

FIG. 6 shows an example of the configuration of the volume reduction pattern of the third embodiment used during the sleep timer mode execution process.

  In this volume reduction pattern, the volume level at the start of the rest timer mode is set to the same constant volume level (fixed value) L43 for the three types of timer times 30 minutes, 60 minutes, and 90 minutes, and from this fixed value L43. The volume is set to gradually decrease at the same level regardless of the timer time. This volume reduction pattern is a pattern in which the timer time is 90 minutes and the playback volume is reduced to almost zero immediately before the timer time elapses. When the timer time is set to 30 minutes, for example, the music disc 13 is still being played at a certain volume level L2 just before the end of the timer time 30 minutes, but the power is turned off at this volume level L42. It will be. Further, when the timer time is set to 60 minutes, for example, the music disc 13 is still played at a certain volume level L41 just before the end of the timer time 60 minutes, but the power is turned off at this volume level L1. It will be.

[Example 4]
The fourth embodiment is a modified embodiment particularly effective for the first embodiment, and is a case where the fixed value corresponding to the timer time is higher than the reproduction volume level before setting the sleep timer mode.

FIG. 7 shows a configuration example of a volume reduction pattern according to the fourth embodiment which is used during the sleep timer mode execution process.

The configuration of the volume lowering pattern itself is the same as in the case of the first embodiment (see FIG. 4), but the rest timer mode execution processing in the disk side microcomputer 11 using this volume lowering pattern is different. In other words, when the fixed values L21, L22, and L23 are higher than the playback volume level L20 of the music disc 13 at that time when the shift to the sleep timer mode is made, the playback volume level L20 is maintained. The point is to start the break timer mode. Then, when the playback volume level matches the volume level of the volume reduction pattern of the corresponding timer time, the playback volume is controlled to be gradually decreased according to the volume reduction pattern thereafter.

  In other words, when the user is watching the TV at a low volume and the sleep timer mode is set, a certain volume level set corresponding to the sleep timer mode is currently being watched. It can be higher than the volume level. In this case, in the second embodiment, there is a situation where the volume is slightly increased at that time point. However, according to the fifth embodiment, even if the sleep timer mode is set, the reproduction volume is not increased until then. Since the viewing volume is maintained as it is, it is possible to prevent a problem that the volume increases unexpectedly.

  In the above embodiment, it is assumed that the music disc 13 is being played back when the sleep timer mode is selected. However, although the music disk 13 is loaded, the disk device may not perform the reproducing operation. In this case, the disc-side microcomputer 11 performs normal auto-repeat playback that repeats playback from the beginning of the loaded music disc 13 and goes back to the beginning when it reaches the end, or random auto What is necessary is just to comprise so that repeat reproduction | regeneration may be performed. Further, when program playback is set by the user, auto-repeat playback may be performed according to the program playback. In any case, by performing auto-repeat playback, it is possible to continue playing the music disk until the end of the timer time regardless of the timer time set by the user.
