[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings.
[0016]
FIG. 1 is a block diagram showing an example of an MD apparatus applied as an audio reproducing apparatus according to the present invention. This MD device reproduces music recorded on the MD, records music on the MD, and has a function of grouping a plurality of music based on a certain standard. Things. In this MD device, the total number of groups is determined to be a maximum of 99 according to the standard.
[0017]
This MD device includes a control unit 1, an operation unit 2, and a display unit 3. The control unit 1 is composed of, for example, a microcomputer, and controls the overall control of the MD apparatus. The control unit 1 controls each unit based on an operation program stored in a memory 16 described later, an operation signal from the operation unit 2 by a user operation, and the like.
[0018]
The operation unit 2 is provided with a plurality of keys (not shown), and when a user operates these keys, an operation signal is transmitted to the control unit 1 to insert and eject an MD, play, stop, record, and the like. MD recording / playback control is performed.
[0019]
The display unit 3 includes, for example, a liquid crystal display, and guides and displays the music being reproduced and the operation of the MD device.
[0020]
The control unit 1 is connected to a servo circuit 4 for accessing the MD. The head unit 5 and the RF amplifier 6 are connected to the servo circuit 4.
[0021]
The head unit 5 includes a spindle motor (not shown) for rotating the MD, a pickup (not shown) for reading and writing data recorded on the MD, and the like. The servo circuit 4 controls the head unit 5 based on a control signal from the control unit 1.
[0022]
The RF amplifier 6 amplifies a reproduction signal (song information) sent from the head unit 5 via the servo circuit 4 and supplies the amplified signal to the address decoder 7.
[0023]
The address decoder 7 decodes the address of the music information based on the reproduction signal from the head unit 5, and the decoded music information is sent to a signal processing unit 10 described later.
[0024]
The signal processing unit 10 and the memory control circuit 11 are connected to the control unit 1. The signal processing unit 10 is realized by a so-called ATRAC (Adaptive Transform Acoustic Coding) LSI, and performs compression encoding and decoding of music information.
[0025]
The signal processing unit 10 is connected with a DAC (Digital Analog Converter) 12 and an ADC (Analog Digital Converter) 13. The DAC 12 converts digital data from the signal processing unit 10 into an analog music signal and supplies the analog music signal to an analog output terminal 14. The ADC 13 converts an analog music signal from the analog input terminal 15 into digital data and supplies the digital data to the signal processing unit 10.
[0026]
The memory control circuit 11 connects the memory 16 and controls the memory 16 based on a control signal from the control unit 1. The memory 16 is composed of, for example, a DRAM, and functions as a buffer memory when recording or reproducing music information.
[0027]
The MD used in the MD device has a data storage area in which a disc name, a song name of a song, and the like are recorded. In the data storage area, as shown in FIG. Is recorded in a table format. According to the figure, the list stores the track names of the tracks corresponding to the respective track numbers (here, there are 20). Here, the term “track” refers to a song. The list is read by the MD device when the MD is inserted into the MD device, transferred to the memory 16, and temporarily stored.
[0028]
In this embodiment, a track attribute is added to each track name. Here, the attribute is information (for example, genre name or artist name) for classifying tracks for grouping tracks. For example, according to FIG. 2, “Jazz” is set as an attribute to the track name stored in “track1” having the track number “1”, that is, the actual track name is set in the track name. Is followed by “Jazz” via “/”. These attributes are set when the MD is inserted into the MD device by the user using the operation unit 2 in advance.
[0029]
In this MD device, the tracks shown in FIG. 2 are grouped based on the attribute added to the track name of each track. That is, tracks having the same attribute are put together and registered as a group. The list shown in FIG. 2 shows a track when dubbing is performed from a plurality of single CDs, for example. Therefore, genres, which are attributes of the track, are stored in a non-uniform order.
[0030]
Next, a control operation of the control unit 1 will be described with reference to a flowchart shown in FIG. For example, when the user edits (groups) tracks in the MD using the MD device, the control unit 1 determines whether or not a track exists in the MD (S1).
[0031]
If there is no track (S1: NO), the process ends. On the other hand, when a track exists (S1: YES), it is determined whether or not an operation for performing grouping has been performed by the user via the operation unit 2 (S2).
[0032]
If the user does not perform an operation to perform grouping (S2: NO), the process ends. On the other hand, when it is determined that an operation to perform grouping has been performed (S2: YES), the variable N is set to “1” (S3). Here, the variable N is a value representing a track number on the list (see FIG. 2).
[0033]
Next, the variable M and the variable A are set to “0” (S4). Here, the variable M is a value representing the total number of tracks when there is a track having the same genre name, and the variable A is a value representing a track number on the list when a new genre name is confirmed. It is.
[0034]
Next, the N-th track name of the track number is confirmed (S5), and it is determined whether or not the track name has an attribute indicating a genre (S6). Specifically, it is determined whether or not the character “/” is inserted in the track name. If the character "/" is inserted in the track name, then the genre is inserted, and it is determined that there is data representing the genre.
[0035]
If there is no genre in the track name (S6: NO), the process proceeds to step S11 described later. On the other hand, if the track name has a genre (S6: YES), it is determined whether or not the variable M is "0" (S7). When the variable M is “0”, that is, when the genre name is newly determined, the value of the variable N is replaced with the variable A (S8). For example, if the variable N is “1”, the variable A is set to “1”.
[0036]
Then, for example, the genre name (for example, “Jazz”) included in the track of track number 1 is temporarily stored in the memory 16 (S9). Next, a value obtained by adding “1” to the variable M is set as a variable M (S10). For example, when the genre name is newly determined, “1” is set.
[0037]
Next, it is determined whether or not the last track has been confirmed (S11). If the last track has not been confirmed (S11: NO), a value obtained by adding “1” to the variable N is set as the variable N (S12). This is for confirming the track of the next track number on the list. After that, the process returns to step S5.
[0038]
Similarly, for the track having the next track number, it is determined whether or not the track name has a genre name (S5, 6), and it is determined whether or not the variable M is "0" (S7). Here, in step S7, if the variable M is not "0" (S7: NO), that is, if the variable M is 1 or more, the genre name of the next track name is stored in the memory 16 first. It is determined whether it is the same as (S13). If the genre names are the same (S13: YES), the Nth track is moved to the (A + M) th track number (S14, see FIG. 5B).
[0039]
After the movement of the track, the process proceeds to step S10, and the value obtained by adding “1” to the variable M is set as the variable M. On the other hand, if the genre names are not the same in step S13 (S13: NO), the process proceeds to step S11, in which it is determined whether or not the last track has been confirmed.
[0040]
That is, in the processing of steps S5 to S14, it is checked whether or not the genre name “Jazz” is included in the track name for all the tracks (track 1 to track 20). As shown in 5B, the track is moved so that tracks of the same genre name are continuous. By this processing, the tracks having the genre name “Jazz” are arranged collectively as shown in FIG. 6C.
[0041]
Next, when it is determined in step S11 that the last track has been confirmed (S11: YES), it is determined whether or not the variable M is 2 or more (S15 in FIG. 4). When the variable M is 2 or more (S15: YES), that is, when the total number of tracks of the same genre is 2 or more, from the variable Ath track number to the (variable A + variable M-1) th track number Are recognized as tracks having the same genre name (see C in FIG. 6), and are grouped (S16). Specifically, data (for example, “0; MD DISK NAME // 1-8; Jazz”) indicating that the data is grouped is written in the data storage area of the MD disk name.
[0042]
Thereafter, the sum of the variables A and M is replaced with the variable N (S16). This is for confirming the next track after the grouped tracks. Next, it is determined whether or not the variable N has become equal to or more than the maximum number of tracks (S18). If the variable N has become equal to or more than the maximum number of tracks (S18: YES), this processing is terminated as that the last track has been confirmed. I do. On the other hand, if the variable N is not equal to or greater than the maximum number of tracks (S18: NO), the process returns to step S4 in FIG.
[0043]
If the variable M is not 2 or more in step S15 (S15: NO), it is determined whether or not the variable A is "0" (S19). If the variable A is "0" (S19: YES), it is determined that the genre has not been detected, and a value obtained by adding "1" to the variable N is set as the variable N (S20), ie, the next track on the list. The process proceeds to step S18 in order to confirm the track of the number. If the variable A is not “0” in step S19 (S19: NO), a value obtained by adding “1” to the variable A is set as a variable N (S21). This indicates a case where a genre is detected but the number of tracks having that genre name is one, and in this case also, the process proceeds to step S18.
[0044]
As described above, when the user inputs a genre name as an attribute of a track to each track stored in the MD, as shown in FIG. 7, a plurality of tracks are set to “Jazz”, “Classic”, And "Pops". At this time, in the data storage area of the MD disk name, for example, "0; MD DISK NAME // 1-8; Jazz // 9-14; Classic // 15- 20; Pops // ").
[0045]
Therefore, the user can easily group a plurality of types of tracks without moving a plurality of desired tracks to be grouped by a troublesome operation. Then, the user can enjoy the performance by reproducing the grouped tracks. Therefore, a highly convenient sound reproducing device can be provided.
[0046]
Note that the attribute set by the user is not limited to the genre described above, and may be, for example, an artist name, an album name, or the like. Further, the user may set an arbitrary attribute (for example, “Favorite”, “2002 Hit”, etc.).
[0047]
By the way, when the user groups a plurality of types of tracks as described above, there is a case where a group is grouped by album as one form. Usually, an album often includes a track to be single-cut, but a user may want to continuously listen to the single-cut track.
[0048]
Usually, in an album, a track to be single-cut is often located in the first song of the album. Therefore, in this embodiment, when one album is grouped into one group by using this habit, the first track of each group is selected, and the selected track is continuously reproduced for each group. ing.
[0049]
Hereinafter, the control operation according to the above embodiment will be described with reference to the flowchart shown in FIG. The control unit 1 first determines whether or not a group exists in the MD (S31). If there is no group in the MD (S31: NO), this processing ends.
[0050]
If there is a group in the MD (S31: YES), it is determined whether or not the user has selected a mode for playing the first song of the group (S32). If the mode for playing the first music of the group has not been selected (S32: NO), this processing ends.
[0051]
When the mode in which the first music of the group is continuously performed for each group is selected (S32: YES), the variable G is set to "1" (S33). Here, the variable G is a value indicating the group number.
[0052]
Next, the control unit 1 plays the first song of the G-th group (S34). At the end of the performance, it is determined whether or not the performance of the last group has been completed (S35). When the performance of the last group has been completed (S35: YES), this processing ends.
[0053]
If the performance of the last group is not completed (S35: NO), it is determined whether or not there is a performance stop request by the user's operation (S36). If there is a request to stop the performance (S36: YES), the process is terminated.
[0054]
If there is no request to stop the performance (S36: NO), a value obtained by adding "1" to the variable G is set as the variable G (S37), the process returns to step S34, and returns to the process of playing the first music of the G-th group. . In this case, for example, the first song of the second group is played. That is, only the first song in each group is continuously played until the first song in the last group is played and a stop request for the performance is not operated.
[0055]
In this way, if only the first song of each group is played continuously, for example, the group is grouped by album, and if the first song of each album is a single-cut track, the user may select a single-cut track. You can listen to each album continuously. Therefore, the user can listen to the tracks recorded on the MD with more enjoyment.
[0056]
In the above control, the first track of each group is selected and played. However, the present invention is not limited to this. For example, a track other than the first track such as the second or third track of each group may be selected. . Further, in each group, a plurality of tracks such as a first song and a third song may be selected, and these may be continuously performed for each group.
[0057]
Of course, the scope of the present invention is not limited to the above embodiment. For example, in the above embodiment, the MD device has been described, but the above control may be applied to a CD device or the like instead of the MD device.
