[0030]
(Second embodiment)
Next, a second embodiment of the present invention will be described. FIG. 4 is a block diagram illustrating an example of a functional configuration of a microprocessor 4 ′ according to the second embodiment and peripheral components thereof. Note that in FIG. 4, components denoted by the same reference numerals as those illustrated in FIG. 2 have the same functions, and thus redundant description will be omitted.
[0031]
The microprocessor 4 'shown in FIG. 4 includes a rearrangement processing unit 46 having another function instead of the rearrangement processing unit 45 shown in FIG. The microprocessor 4 'further includes a period registration unit 47. On the other hand, the received program registration unit 41 shown in FIG. 2 is not provided. Further, outside the microprocessor 4 ', a number-of-times variable memory 11, a days count memory 12, and a timer 13 are further provided. Other overall configurations are the same as those in FIG.
[0032]
The period registration unit 47 registers a reception period desired by the user (for example, an arbitrary number of days N such as one month) based on the operation of the operation unit 6 by the user. In the present embodiment, as described above, the received program registration unit 41 of FIG. 2 is not provided, and the accompanying information acquisition unit 42 and the analysis unit 44 not only receive the specific broadcast program but also the reception program registered in the period registration unit 47. Acquisition information associated with all broadcast programs received during the period is acquired and converted to ASCI codes. The accompanying information also includes song name information of the song actually broadcast.
[0033]
The timer 13 performs a timing operation, and increments the count value M stored in the day count memory 12 by one every day.
[0034]
The rearrangement processing unit 46 collates the accompanying information (song name information) of the FM multiplex broadcast converted into the ASCI code with the attribute information (song name list) of each song recorded on the hard disk 5 and stores the same in the hard disk 5. The number of times each of the recorded songs is broadcast during the registration reception period is counted. Then, the count value for each music is stored in the frequency variable memory 11 as a frequency variable Xn (n is an identification variable of each music). Further, when the number-of-days count value M stored in the number-of-days memory 12 reaches the number N of days of the reception period registered in the period registration unit 47, the rearrangement processing unit 46 sorts the value of the number-of-times variable Xn in descending order. A plurality of songs in the hard disk 5 are rearranged.
[0035]
Hereinafter, the operation of the audio system 100 according to the second embodiment configured as described above will be described. FIG. 5 is a flowchart showing the operation of the audio system 100 according to the second embodiment. It is assumed that the counting operation of the day count value M is performed by the timer unit 13 separately from the operation of this flowchart.
[0036]
In FIG. 5, the rearrangement processing unit 46 compares the day count value M stored in the day count memory 12 with the number N of days of the reception period registered in the period registration unit 47, and determines whether the two values are the same. Is determined (step S11). If they are not the same, it is determined whether or not FM multiplex broadcasting is being received (step S12). If it is being received, it is further determined whether or not the accompanying information can be received (step S13).
[0037]
If the incidental information can be received, the incidental information is actually acquired by the incidental information acquisition unit 42, and is converted into an ASCI code by the analysis unit 44 (step S14). Then, the rearrangement processing unit 46 compares the accompanying information (song name information) of the FM multiplex broadcast converted into the ASCI code with the attribute information (song name list) of each song recorded on the hard disk 5, and It is determined whether or not the music received by the multiplex broadcast is recorded in the hard disk 5 (step S15).
[0038]
If it is determined that the corresponding music is registered in the hard disk 5, the number variable Xn of the music is incremented by one and stored in the number variable memory 11 (step S16). On the other hand, when it is determined that the corresponding music is not registered in the hard disk 5, the music title information of the music is registered in the hard disk 5, and the number variable Xn of the music is registered in the number variable memory 11 and incremented by one. (Step S17). After step S16 or step S17, the process returns to step S12 to continue the acquisition processing of the accompanying information.
[0039]
If it is determined in the first step S11 that the day count value M stored in the day count memory 12 and the number N of days of the reception period registered in the period registration unit 47 are the same value, Based on the frequency variable Xn of each music stored in the frequency variable memory 11, the plurality of music in the hard disk 5 are rearranged in the hit chart folder in descending order of on-air frequency (step S18). Thereafter, after clearing the day count value M and the number variable Xn to 0 (step S19), the process returns to step S11.
[0040]
As described in detail above, according to the second embodiment, the reception frequency of songs broadcast during a predetermined period registered in advance is counted, and the songs in the hard disk 5 are sorted in descending order of frequency. Therefore, even if a specific hit chart program is not received, the music can be automatically rearranged with the reception frequency during a certain period as a hit chart.
[0041]
Further, in the present embodiment, since the rearrangement is performed according to the actually received broadcast program, the music can be rearranged based on the user's own ranking. Broadcast programs actually received by the user are often user-preferred, and the music being broadcast among them is often suited to the user's preference. Therefore, according to the present embodiment, a plurality of music pieces can be automatically rearranged according to a ranking that suits individual user preferences.
[0042]
In the second embodiment, an example is described in which the reception frequency of each song is counted based on the song name information included in the accompanying information of the FM multiplex broadcast, and the hit chart folder is rearranged according to the reception frequency. Although described, it is not limited to this. For example, an artist-specific folder is created using artist name information included in the attribute information of the music recorded on the hard disk 5 or the accompanying information of the FM multiplex broadcast, and the music of the specific artist is created based on the number-of-times variable Xn. The chart may be rearranged to generate a chart for each artist. In this way, it is possible to create an original album of songs broadcast for a specific artist during a certain period. When genre information is included in the accompanying information or the attribute information, a genre-specific chart can be generated using the genre information.
[0043]
Also, using the artist name information included in the accompanying information of the FM multiplex broadcast, the plurality of songs recorded on the hard disk 5 are sorted in the order of the number of broadcasts of a plurality of broadcast programs during a certain period. You may do it. For example, a few songs of the most frequently broadcast artist are arranged in order from the first song, and then a few songs of the most frequently broadcast artist are arranged in succession.
[0044]
Also in the second embodiment, it is not essential that the microprocessor 4 obtain the attribute information from the hard disk 5, as in the first embodiment. That is, the rearrangement processing unit 46 searches the hard disk 5 using the song name information included in the accompanying information of the FM multiplex broadcast as a key, increments the number variable Xn corresponding to the song hit in the search by one, and increments the number variable. It may be stored in the memory 11.
[0045]

FIG. 7 is a flowchart showing the operation of the audio system 100 according to the second embodiment. Note that, in FIG. 7, portions denoted by the same step numbers as those in FIG. 5 are portions that perform the same processing, and thus redundant description will be omitted here.
[0050]
In FIG. 7, as a result of determining whether or not the day count value M stored in the day count memory 12 and the number of days N of the reception period registered in the period registration unit 47 are the same (step S11), they are not the same. If it is determined, the microprocessor 4 checks the source setting mode (step S21). Here, if the mode is the reception mode of the FM multiplex broadcast, the processes of steps S13 to S17 are performed as in FIG.
[0051]
On the other hand, if the mode is set to a mode other than the reception mode of FM multiplex broadcasting (playback mode of CD, MD, DVD, etc.), whether the accompanying information can be acquired from those sources, that is, the second attribute It is determined whether information has been added (step S22). If the second attribute information can be obtained, the information is actually obtained by the second attribute information obtaining unit 48, and the obtained information is converted into an ASCI code by the analysis unit 44 (step S23).
[0052]
Next, the rearrangement processing unit 46 compares the second attribute information (song name information) converted into the ASCI code with the attribute information (song name list) of each song recorded on the hard disk 5, and compares the CD information. It is determined whether the music reproduced from the source such as is also recorded in the hard disk 5 (step S24).
[0053]
If it is determined that the corresponding music is registered in the hard disk 5, the number variable Xn of the music is incremented by one and stored in the number variable memory 11 (step S25). On the other hand, when it is determined that the corresponding music is not registered in the hard disk 5, the music title information of the music is registered in the hard disk 5, and the number variable Xn of the music is registered in the number variable memory 11 and incremented by one. (Step S26). After step S25 or step S26, the process returns to step S21 to continue the acquisition process of the accompanying information.
[0054]
As described in detail above, according to the third embodiment, in addition to the reception frequency of music received by FM multiplex broadcasting, the reproduction frequency of music such as CDs, MDs, and DVDs that the user has voluntarily reproduced is determined.
