FIG. 1 is a functional block diagram showing a main part of the content reproduction apparatus according to Embodiment 1 of the present invention. FIG. 2 is an explanatory diagram showing an example of a reservation acceptance screen according to Embodiment 1 of the present invention. FIG. 3 is an explanatory diagram showing an example of a reservation guide image according to Embodiment 1 of the present invention. FIG. 4 is a hardware configuration diagram showing a main part of the content reproduction apparatus according to Embodiment 1 of the present invention. FIG. 5 is another hardware configuration diagram showing the main part of the content reproduction apparatus according to Embodiment 1 of the present invention. With reference to FIG. 1 to FIG. 5, the content reproduction apparatus 100 according to the first embodiment will be described focusing on an example in which the content reproduction apparatus 100 is mounted on a vehicle 1 formed of a four-wheeled vehicle.

  The radio receiver 2 is configured by a dedicated receiver mounted on the vehicle 1, for example. The radio receiver 2 receives a broadcast wave of a radio broadcast and outputs audio information included in the broadcast wave to the content reproduction device 100.

  The optical disk drive 6 is provided, for example, in a vehicle information device (not shown) (hereinafter simply referred to as “vehicle information device”) mounted on the dashboard of the vehicle 1. The optical disc drive 6 reads audio information such as music stored on the optical disc and outputs the audio information to the content reproduction apparatus 100.

  The radio receiver 2 and the optical disc drive 6 constitute a source 8.

  Each audio source included in the source 8 outputs information related to content corresponding to each audio information (hereinafter referred to as “content information”) to the content reproduction apparatus 100 in addition to the audio information. For example, the radio receiver 2 outputs content information indicating the broadcast station name of each broadcast station in radio broadcasting, the frequency of each broadcast station, and the like. The optical disc drive 6 outputs content information indicating the track number of each song stored on the optical disc, the playback time of each song, and the like.

  The display device 11 is configured by a display 12 provided in an in-vehicle information device, for example. The display 12 uses, for example, a liquid crystal display or an organic EL (Electro-Luminescence) display. The audio output device 13 is constituted by, for example, a speaker 14 provided in the in-vehicle information device. The operation input device 15 is configured by, for example, a touch panel 16 provided integrally with the display 12.

  The shift position sensor 17 detects a shift position of a not-shown transmission (hereinafter simply referred to as “transmission”) mounted on the vehicle 1, and a signal indicating the shift position (hereinafter referred to as “shift position signal”). ) Is output. An electronic control unit (hereinafter referred to as “ECU”) 18 outputs a shift position signal input from the shift position sensor 17 to the content reproduction apparatus 100.

  The audio reproducing unit 21 reproduces the content of audio information input from the source 8, that is, audio content. The audio reproduction unit 21 causes the audio output device 13 to output audio corresponding to the reproduced audio content. The audio playback unit 21 constitutes a content playback unit 23.

  The content selection unit 24 causes the display device 11 to display a screen (hereinafter referred to as “selection screen”) on which content to be played back by the content playback unit 23 among the content that can be played back by the content playback unit 23 can be selected. It is.

  For example, when the content reproduction unit 23 can acquire audio information from the radio receiver 2, the selection screen is a radio broadcast channel selection screen. On the channel selection screen, for example, the broadcast station name of each broadcast station and the frequency of each broadcast station are displayed. When the content reproduction unit 23 can acquire audio information from the optical disc drive 6, the selection screen is a music selection screen for music stored on the optical disc. On the music selection screen, for example, the track number of each song stored on the optical disc, the playback time of each song, and the like are displayed.

  In a state where the selection screen is displayed on the display device 11, when the operation for selecting the content is input to the operation input device 15 with respect to the content displayed on the selection screen, the content reproduction unit 23 Playback is started.

  The time output unit 25 is constituted by a timer circuit, for example, and measures the current time. The time output unit 25 outputs information indicating the current time (hereinafter referred to as “time information”) to the content reproduction unit 23, the reservation receiving unit 26, and the reservation guide unit 27.

  The reservation receiving unit 26 sets the time after the current time (hereinafter referred to as “first time”) and the content that the content playback unit 23 plans to start playback at the first time (hereinafter referred to as “first content”). The reservation including it is accepted. That is, the reservation receiving unit 26 displays a reservation receiving screen on the display device 11 when an operation for instructing display of a screen for receiving the reservation (hereinafter referred to as “reservation receiving screen”) is input to the operation input device 15. Is.

  FIG. 2 shows an example of a reservation acceptance screen. The reservation acceptance screen shown in FIG. 2 is a screen for accepting reservations for audio content by radio broadcasting.

  In the first area A in the reservation acceptance screen, the scheduled reproduction start time of the first content, that is, the first time is displayed. In the first area A, the scheduled playback end time of the first content is displayed. The scheduled reproduction start time (first time) and the scheduled reproduction end time can be changed by operating the operation input device 15.

  Content information regarding the first content is displayed in the second area B in the reservation reception screen. Specifically, the name of the broadcasting station and the frequency of the broadcasting station are displayed. The first content can be changed by operating the operation input device 15.

  In the third area C in the reservation reception screen, buttons C1 and C2 for determining whether or not to execute a reservation with the contents displayed in the first area A and the second area B are displayed. When the button C <b> 1 is pressed by operating the operation input device 15, the reservation receiving unit 26 notifies the content reproduction unit 23 and the reservation guide unit 27 of the details of the reservation. On the other hand, when the button C2 is pressed, the reservation accepting unit 26 ends the process of displaying the reservation accepting screen without notifying the content reproducing unit 23 and the reservation guiding unit 27 of the content of the reservation.

  Here, in a state where the selection screen is displayed on the display device 11, the reservation receiving unit 26 performs a predetermined operation (hereinafter referred to as “non-selection operation”) on the content displayed on the selection screen, which is different from the operation of selecting the content. ”) Is input to the operation input device 15, a reservation reception screen different from the normal reservation reception screen is displayed on the display device 11 as follows. That is, the reservation acceptance screen at this time is the same screen as in FIG. 2, and the same time as the current time is set as the scheduled playback start time (first time) in the initial state, and the non-selection operation is performed in the initial state. This is a screen in which the content that is input is set as the first content. Further, on the reservation acceptance screen, the scheduled playback start time (first time) and scheduled playback end time can be changed by operating the operation input device 15, and the first content can also be changed by operating the operation input device 15. . The non-selection operation is set to a so-called “long press” operation, for example.

  The reservation guide unit 27 uses the shift position signal acquired from the ECU 18 to determine whether or not the transmission is set to a parking range (hereinafter referred to as “P range”). If the current time is between the first time and a time before the first time (hereinafter referred to as “second time”), the reservation guide unit 27 sets the transmission to the P range. In other words, when the range other than the P range (hereinafter referred to as “other range”) is switched to the P range, an image (hereinafter referred to as “reservation guide image”) indicating the content of the reservation input from the reservation receiving unit 26. ) Is displayed on the display device 11. The predetermined time between the first time and the second time is set to 1 hour, for example.

  FIG. 3 shows an example of the reservation guide image. A rectangular reservation guide image D is displayed at the center of the screen of the display device 11. The reservation guide image D includes text indicating the scheduled reproduction start time (first time) and the source 8 corresponding to the first content. The reservation guide image D is displayed by a so-called “pop-up”.

  Here, when the current time becomes the same time as the first time, the content reproduction unit 23 determines whether or not the first content is already being reproduced, and the content different from the first content (hereinafter referred to as “first”). It is determined whether or not “2 contents” is being reproduced. If the first content is already being played back at the first time, the content playback unit 23 continues to play back the first content. In addition, when the first content is not being reproduced at the first time and the second content is not being reproduced, the content reproduction unit 23 starts reproduction of the first content.

  When the second content is being reproduced at the first time, the content reproduction unit 23 superimposes the first content and the second content for a preset time (hereinafter referred to as “superimposition reproduction time”). Content (hereinafter referred to as “superimposed content”). For example, when the first content and the second content are audio content, the content reproduction unit 23 causes the audio output device 13 to output both the audio corresponding to the first content and the audio corresponding to the second content. . The superimposed reproduction time is set to 10 seconds, for example.

  In the superimposed reproduction time, the content reproduction unit 23 gradually decreases the ratio of the second content in the superimposed content over time. Specifically, for example, the content reproduction unit 23 performs so-called “cross-fade reproduction”. That is, when the first content and the second content are audio contents, the content reproduction unit 23 gradually decreases the sound volume corresponding to the second content and gradually increases the sound volume corresponding to the first content. . As a result, the content reproduction unit 23 shifts to reproduction of only the first content at the same time as the reproduction of the superimposed content is completed.

  Further, the content playback unit 23 ends the playback of the first content at the scheduled playback end time based on the details of the reservation input from the reservation receiving unit 26. At this time, when the second content is being played back at the first time, the content playback unit 23 resumes the playback of the second content. For example, when the second content is radio broadcast audio content, the content reproduction unit 23 resumes reproduction of the audio content of the same broadcast station as that reproduced at the first time. When the second content is audio content of music, the content playback unit 23 starts from the beginning of the music played back at the first time, or the location when the crossfade playback of the music ends. Resume playback from.

  The content reproduction device 100 is configured by the content reproduction unit 23, the content selection unit 24, the time output unit 25, the reservation reception unit 26, and the reservation guide unit 27. The content reproduction apparatus 100 is provided, for example, in an in-vehicle information device.

  FIG. 4 shows an example of the hardware configuration of the content reproduction apparatus 100. As shown in FIG. 4, the content reproduction apparatus 100 is configured by a computer, and includes a processor 31 and a memory 32. The memory 32 stores a program for causing the computer to function as the content reproduction unit 23, the content selection unit 24, the time output unit 25, the reservation reception unit 26, and the reservation guide unit 27 illustrated in FIG. The processor 31 reads out and executes the program stored in the memory 32, thereby realizing the functions of the content reproduction unit 23, the content selection unit 24, the time output unit 25, the reservation receiving unit 26, and the reservation guide unit 27 illustrated in FIG. Is done.

  The processor 31 is configured by, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), a microcontroller, or a microprocessor. The memory 32 is, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), or an EEPROM (Electrically Erasable Programmable Memory). (Hard Disk Drive) or the like.

  FIG. 5 shows another example of the hardware configuration of the content reproduction apparatus 100. As shown in FIG. 5, the content reproduction apparatus 100 is configured by a dedicated processing circuit 33. The processing circuit 33 is, for example, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), a system LSI (Large-Scale Integration), or a combination thereof.

  1 may be realized by the processing circuit 33, or the function of each unit may be realized by the processing circuit 33. May be realized together by the processing circuit 33. Further, some of the functions of the content reproduction unit 23, content selection unit 24, time output unit 25, reservation receiving unit 26, and reservation guide unit 27 shown in FIG. 1 are realized by the processor 31 and the memory 32 shown in FIG. The remaining functions may be realized by the processing circuit 33 shown in FIG.

  Next, with reference to the flowchart of FIG. 6, the operation of the content reproduction apparatus 100 will be described focusing on the operation of the reservation receiving unit 26. In the initial state, the content selection unit 24 displays a selection screen on the display device 11.

  First, in step ST <b> 1, the reservation receiving unit 26 determines whether or not a non-selection operation for content displayed on the selection screen has been input to the operation input device 15. When a non-selection operation is input (step ST1 “YES”), the reservation receiving unit 26 acquires time information from the time output unit 25 in step ST2.

  Next, in step ST3, the reservation receiving unit 26 causes the display device 11 to display a reservation receiving screen. The reservation reception screen at this time shows the time information acquired in step ST3 in the initial state where the content for which the non-selection operation is input in step ST1 is set as the first content in the initial state. The same time as the current time is set as the first time.

  After step ST3, the first time and the first content displayed on the reservation acceptance screen are appropriately changed by the operation of the operation input device 15. Thereby, a desired first time and first content are set.

  Next, in step ST4, the reservation receiving unit 26 determines whether or not to execute a reservation based on the content displayed on the reservation receiving screen. Specifically, for example, the reservation receiving unit 26 determines which of the buttons C1 and C2 is pressed on the reservation receiving screen illustrated in FIG.

  When a reservation is executed (step ST4 “YES”), that is, when the button C1 is pressed, in step ST5, the reservation receiving unit 26 notifies the content reproduction unit 23 and the reservation guide unit 27 of the content of the reservation. . Next, in step ST <b> 6, the reservation receiving unit 26 ends the process for displaying the reservation receiving screen on the display device 11. Thereby, the screen of the display device 11 returns to the selection screen.

  On the other hand, when the reservation is not executed (step ST4 “NO”), that is, when the button C2 is pressed, the reservation receiving unit 26 performs the step without notifying the content reproduction unit 23 and the reservation guide unit 27 of the contents of the reservation. Proceeding to ST6, the process for displaying the reservation acceptance screen on the display device 11 is terminated.

  As described above, the content reproduction apparatus 100 according to the first embodiment automatically displays the reservation reception screen in which the first content and the first time are set in advance by inputting a non-selection operation on the content displayed on the selection screen. . Thereby, it is possible to reduce the number of operation inputs until the transition from the selection screen to the reservation acceptance screen, thereby reducing the user's trouble. Further, for example, even when the user does not know the broadcast station name of the broadcast station to be reserved or the track number of the music to be reserved, a smooth reservation can be made based on the selection screen.

  Next, with reference to the flowchart of FIG. 7, the operation of the content reproduction apparatus 100 will be described focusing on the operation of the reservation guide unit 27. In the initial state, the reservation receiving unit 26 has already received a reservation, and the reservation guide unit 27 stores the contents of the reservation in the memory 32 or the like. The details of the reservation include at least a first time and content information regarding the first content.

  First, in step ST11, the reservation guide unit 27 acquires a shift position signal from the ECU 18. Next, in step ST12, the reservation guide unit 27 determines whether or not the transmission is set to the P range using the shift position signal acquired in step ST11. When the transmission is set to another range (step ST12 “NO”), the reservation guide unit 27 returns to step ST11.

  On the other hand, when the transmission is set to the P range (step ST12 “YES”), the reservation guide unit 27 acquires time information from the time output unit 25 in step ST13. Next, in step ST14, the reservation guide unit 27 determines whether or not the current time is a time between the first time and the second time, using the time information acquired in step ST13.

  When the current time is between the first time and the second time (step ST14 “YES”), the reservation guide unit 27 causes the display device 11 to display the reservation guide image in step ST15.

  When the current time is not the time between the first time and the second time (step ST14 “NO”), or after step ST15, at step ST16, the reservation guide unit 27 uses the time information acquired at step ST13. Then, it is determined whether or not the current time is a time after the first time.

  If the current time is not after the first time (step ST16 “NO”), the reservation guide unit 27 returns to step ST11. At this time, when the reservation guide image is displayed on the display device 11, the reservation guide unit 27 continues the process of displaying the reservation guide image. On the other hand, if the current time is a time after the first time (step ST16 “YES”), the reservation guide unit 27 ends the process.

  Thus, when the current time is between the first time and the second time, content reproduction apparatus 100 according to Embodiment 1 displays the reservation guide image when the transmission is set to the P range. Thereby, for example, when traveling on an expressway, the reservation guide image is displayed when the vehicle 1 stops in the parking area or the service area immediately before the first time. As a result, it is possible to avoid viewing and missing the reserved first content due to the passenger getting off the vehicle for a long time for a break or the like.

  Next, with reference to the flowchart of FIG. 8, the operation of the content playback apparatus 100 will be described focusing on the operation of the content playback unit 23 at the scheduled playback start time (first time). In the initial state, the reservation receiving unit 26 has already received a reservation, and the content reproduction unit 23 stores the details of the reservation in the memory 32 or the like. The details of the reservation include at least a first time and content information regarding the first content.

  First, in step ST <b> 21, the content reproduction unit 23 acquires time information from the time output unit 25. Next, in step ST22, the content reproduction unit 23 determines whether or not the current time indicated by the time information acquired in step ST21 is the same time as the first time. When the current time is different from the first time (step ST22 “NO”), the content reproduction unit 23 returns to step ST21.

  On the other hand, when the current time is the same as the first time (step ST22 “YES”), in step ST23, the content reproduction unit 23 determines whether or not the first content is already being reproduced. For example, when the user has started the reproduction of the first content manually by operating the operation input device 15 before the first time, the content reproduction unit 23 is already reproducing the first content at the first time. It is. In such a case (step ST23 “YES”), the content reproduction unit 23 proceeds to step ST29 and continues reproduction of the first content.

  When the first content is not being reproduced (step ST23 “NO”), in step ST24, the content reproduction unit 23 determines whether or not the second content different from the first content is being reproduced. When the second content is not being reproduced (step ST24 “NO”), the content reproduction unit 23 starts reproduction of the first content in step ST25. Next, the content reproduction unit 23 proceeds to step ST29 and continues to reproduce the first content.

  When the second content is being reproduced (step ST24 “YES”), in step ST26, the content reproduction unit 23 starts reproduction of the superimposed content in which the first content and the second content are superimposed. The content reproduction unit 23 continues to reproduce the superimposed content for a preset superimposed reproduction time.

  In the superimposed reproduction time, the content reproduction unit 23 gradually decreases the ratio of the second content in the superimposed content over time (step ST27). Thereby, when the reproduction of the superimposed content is finished, the content reproduction unit 23 shifts to a state of reproducing only the first content (step ST28). Next, the content reproduction unit 23 proceeds to step ST29 and continues to reproduce the first content.

  Conventionally, in a content playback apparatus for audio content, when the playback target is switched from the second content to the first content, first, the volume of the second content is gradually decreased, the volume of the second content is reduced to zero, It is known that the reproduction of one content is started and the volume of the first content is gradually increased. In this case, it is possible to reduce a sense of discomfort felt by the user by switching the audio content, while the first content and the second content are similar to each other (for example, when both content are news programs by radio broadcasting). For example, there is a problem that the user does not notice the content switching and misses the first content.

  On the other hand, the content reproduction apparatus 100 according to the first embodiment reproduces the superimposed content during the superimposed reproduction time, and gradually decreases the ratio of the second content by cross-fade reproduction. Thereby, the user can easily notice the switching while reducing the uncomfortable feeling that the user remembers by switching.

  Next, with reference to the flowchart of FIG. 9, the operation of the content reproduction apparatus 100 will be described focusing on the operation of the content reproduction unit 23 at the reproduction end scheduled time. In the initial state, the content reproduction unit 23 is reproducing the first content. The contents of the reservation are stored in the memory 32 and the like, and the content of the reservation includes a scheduled reproduction end time. The memory 32 or the like stores information indicating whether or not the content reproduction unit 23 has reproduced the second content at the first time.

  First, in step ST31, the content reproduction unit 23 acquires time information from the time output unit 25. Next, in step ST32, the content playback unit 23 determines whether or not the current time indicated by the time information acquired in step ST31 is the same time as the scheduled playback end time. If the current time is different from the scheduled playback end time (step ST32 “NO”), the content playback unit 23 continues to play back the first content in step ST33.

  On the other hand, if the current time is the same time as the scheduled playback end time (step ST32 “YES”), the content playback unit 23 ends the playback of the first content in step ST34. Next, in step ST35, the content reproduction unit 23 determines whether or not the second content has been reproduced at the first time. When the second content is being played back at the first time (step ST35 “YES”), the content playback unit 23 resumes the playback of the second content in step ST36.

  As described above, when the content reproduction apparatus 100 according to Embodiment 1 is reproducing the second content at the first time, the reproduction of the second content is automatically resumed when the reproduction of the first content is completed. . As a result, the operation of resuming the reproduction of the second content is unnecessary, and the user's trouble can be reduced.
