BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the playback device 1 according to the present embodiment. However, in the present embodiment, a case where the vehicle is mounted on the vehicle together with the car navigation device 3 will be described as an example.
[0021]
As shown in FIG. 1, the reproducing apparatus 1 according to the present embodiment includes an audio controller 11, a memory controller 12, a ROM (Read Only Memory) 13, a RAM (Random Access Memory) 14, an encoder / decoder 15, a CD reading unit 16, It comprises a source switching section 17, an amplifier 18, and a volume controller 19.
[0022]
As shown, for example, a radio receiving unit 25, a CD reading unit 16 (such as a music CD or CD-ROM, hereinafter referred to as a CD medium), and a recording medium (HDD) 21 are connected to the source switching unit 17. That is, the source switching unit 17 switches the source of the content to output sound from the connected information sources.
[0023]
When the user selects the playback function from the CD media, the audio controller 11 transmits predetermined programs and various information (programs and various information for implementing operations described below) from the ROM 13 or the RAM 14 via the memory controller 12. Load and do this. That is, the source switching unit 17 sets the CD reading unit 16 as an information source, and the input music data is input to the volume controller 19 via the amplifier 18. The audio controller 11 controls the volume controller 19 based on the volume set by the user. The volume controller 19 generates an analog signal having a corresponding amplitude based on the control, and inputs the analog signal to the speaker 22 for reproduction.
[0024]
In such a configuration, when a copy of the music data stored in the CD medium is requested, the audio controller 11 controls the source switching unit 17 to change the output destination of the music data read by the CD reading unit 16 to the encoder / Switch to decoder 15. The encoder / decoder 15 encodes the input music data by a predetermined compression encoding method such as an MPEG method, an MP3 method, or an ATRAC3 method, and stores the encoded data in a recording device (Hard Disk Drive: HDD) 21. The HDD 21 is configured so as to be shared with the navigation device 3, and an area to be assigned to each function is partitioned by a partition.
[0025]
When reproducing the music data recorded on the HDD 21, the audio controller 11 controls the source switching unit 17 to set the information source to the HDD 21 and the output destination to the encoder / decoder 15. The music data decoded by the encoder / decoder 15 is thereafter output from the speaker 22 as an analog signal via the amplifier 18 and the volume controller 19.
[0026]
In the present embodiment, in order to identify each CD medium, information for each CD medium is generated and held. At this time, the information generated includes information read from the CD media, such as the number of music data included in the CD media, the total performance time, and the performance time for each music piece. However, the order of each data is assumed to be the same as the order of the music pieces stored on the original CD medium. Thus, by referring to the TOC information when reproducing the music data copied to the HDD 21, it becomes possible to reproduce the music data in the same order as the original. Further, as shown in FIG. 2, the generated information is stored in predetermined storage means such as HDD 21 or TOC information (Table Of Contents) together with identification information (identification number) uniquely associated with each CD medium. It is stored in the RAM 14 or the like.
[0027]
Next, the operation according to the present embodiment will be described in detail with reference to the drawings. FIG. 3 is a flowchart showing an operation executed when a CD medium is inserted.
[0028]
In FIG. 3, when a CD medium is set (step S101), the audio controller 11 generates TOC information on the CD medium using the CD reading unit 16 (step S102). Next, the audio controller 11 compares the TOC information previously stored in the RAM 14 with the newly read TOC information (step S103), and determines whether or not the same TOC information exists, in other words, It is determined whether or not the CD has already been registered before (step S104).
[0029]
If the same TOC information does not exist as a result of this determination (No in step S104), the audio controller 11 determines that the set CD medium is a new CD medium, and generates an identification number for uniquely identifying the new CD medium. Then, the identification number is associated with the TOC information generated above and stored in, for example, the RAM 14 or the like (step S105). Further, the user displays information on all songs stored on the CD medium via the display device 24 (step S106). At this time, an example of a screen displayed to the user is shown in FIG. On the other hand, as a result of the determination in step S104, when the same TOC information exists (Yes in step S104), the audio controller 11 displays the corresponding TOC information by distinguishing the copied song from the uncopied song. It is displayed on the device 24 (step S109). At this time, an example of a screen displayed to the user is shown in FIG. As described above, when the CD medium is inserted, the TOC information is generated to determine whether or not the CD is a new CD, and the result is displayed, so that the user can easily manage the CD.
[0030]
Thereafter, the audio controller 11 displays a dialog (see FIG. 4C) for instructing the user whether or not to copy the uncopied music to the HDD 21 in a series of flows on the display device 24 (step S107). Thereafter, based on an instruction input from the input device 23 by the user, operations such as reproduction / copy / discharge of the CD are executed. However, the input device 23 and the display device 24 connected to the audio controller 11 and the input device 23 and the display device 24 connected to the navigation controller 31 have the same configuration. In this way, by configuring so as to be able to operate in a series of flows up to copying of an uncopied song, user convenience and operability are improved.
[0031]
Further, in the above flow, an operation when an instruction to copy a song that has not been copied is input will be described in detail with reference to the flowchart of FIG.
[0032]
First, when an instruction to copy a song that has not been copied is input from the dialog (see FIG. 4C) displayed in step S107 in FIG. 3 (step S1081), the audio controller 11 causes the audio controller 11 to copy the song that has already been copied and the uncopied song. A dialog (see FIG. 4 (d)) for distinguishing and displaying music (all uncopied music if a new CD) is displayed (step S1082) and prompting the user to select whether or not to select music to be copied. It is displayed on the display device 24 (step S1083). Here, an example of a display in which the already-copied music and the non-copied music (all uncopied music in the case of a new CD) are distinguished from each other will be described below with reference to FIG.
[0033]
As shown in FIG. 6A, at the time of the first copy (new CD), all songs are listed as selectable songs, and a desired song can be selected from these. In this case, by configuring the display device 24 and the input device 23 as a touch panel with a display function, the user can easily perform the selection input. FIGS. 6B to 6D show display screens in the second and subsequent copies. FIG. 6B shows an example in which a song already copied is blank, and only songs that have not been copied are listed and displayed. (C) shows an example in which all songs included in the TOC information are displayed together with copied / not copied. Also, (d) shows an example in which all songs included in the TOC information are displayed, and already copied or uncopied songs are highlighted or highlighted. In this way, by configuring the user to be able to determine a song that has not been copied, it is possible for the user to select a desired song easily and without duplication.
[0034]
When an instruction to select a song (Yes in FIG. 4D) is input from the user based on such a display (Yes in step S1084), the audio controller 11 sets the audio controller 11 shown in FIG. The tune selected to be copied based on the display is received (step S1085), and the selected tune is encoded based on the above-described configuration and copied to a predetermined area of the HDD 21 (step S1086). On the other hand, when an instruction not to select a song based on the dialog displayed in step S1083 (No in FIG. 4D) is input (No in step S1084), the audio controller 11 deletes all uncopied songs. The selected music piece is encoded in the same manner as described above and copied to a predetermined area of the HDD 21 (step S1086).
[0035]
Thereafter, the copied / not-yet flag in the TOC information stored in the RAM 14 or the like is rewritten to “done” (step S1087), and the copying operation ends. As a result, on the screen that is read (displayed) when the CD medium is inserted next time, the display of copied / not yet updated is updated.
[0036]
Further, the audio controller 11 is configured to be able to reproduce the music copied to the HDD 21 in the original order (the same order as the CD medium) based on the TOC information when reproducing the music for each CD medium. This is realized by the audio controller 11 reading out the TOC information, and reading out and reproducing the music data in the order registered in the TOC information. This will be described in detail with reference to FIG.
[0037]
For example, when the first copy is performed, a total of three songs of the first, third, and seventh songs are copied out of the eight songs, and when the remaining copies are all copied during the second copy, the song data recorded in the HDD 21 The order is the order of copying (1, 3, 7, 2, 4, 5, 6, 8). Therefore, the audio controller 11 reads out the stored TOC information when reproducing from the HDD 21. As described above, in the TOC information, the information of each song is stored in the order of the songs recorded on the original CD medium. Therefore, the audio controller 21 sequentially reads out the song data based on the song information. Play this. Thus, the reproduction order is the same as that of the original CD medium (1, 2, 3, 4, 5, 6, 7, 8).
[0038]
With the configuration and operation as described above, a reproduction apparatus and a reproduction method of the duplicated music data that can reproduce the reproduced music data while faithfully reproducing the music order on the recording medium are realized. In addition, a music data duplication method for enabling reproduction in which the music order on the recording medium is reproduced in this way is also realized.
[0039]
In the above description, a music CD, a CD-ROM, or the like has been described as an example of a recording medium. However, the present invention is not limited to this, and other recording media, such as a DVD (digital video disk) -ROM, may be used. It is the same even if there is. Furthermore, although the HDD has been described as an example of the recording device 21, the present invention is not limited to this, and any device having a storage capacity sufficient to store music data can be applied.
[0040]
As described above, the present invention is not limited to the embodiment described above, and can be implemented with various modifications without departing from the gist thereof. However, it is preferable to provide a function for preventing illegal duplication at the time of copying so as not to infringe copyrights.
[0041]
