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

(1) Configuration of Embodiment FIG. 2 is a block diagram showing an audio system according to an embodiment of the present invention. This audio system 1
Is designed so that the compact disc 3 can be reproduced by the changer 2 by a compact disc player, and music recorded on the compact disc 3
Music input from an external input is dubbed to the storage 4 and can be used.

Here, in the compact disc 3, predetermined additional information is recorded in the lead-in area.
FIG. 1 is a chart showing a data structure of the additional information.
In this embodiment, the additional information is recorded on the compact disc 3 for each music recorded on the compact disc 3. In the additional information, first, a song ID, which is identification data for identifying a song, is set, and subsequently, a song title (song name), an artist name, and the like are assigned by text data. Further, predetermined variable data is subsequently assigned to the additional information.

Here, the variable data is variable data generated by digitizing various impressions received from the information, and is composed of data of a brightness value, a tempo value, and a loudness value. Here, the brightness value is an index indicating the brightness of the music, the tempo value is an index indicating the speed of the music, and the loudness value is an index indicating the loudness of the music. These are represented by numerical values in the range of values +1 to -1 by relative comparison with reference music in which these variable data are set in advance, such as the hardness of minerals.

Thus, for example, in the case of extremely dark, normal tempo, and noisy music, this variable data is set to [-1, 0, +1]. Thus, even when the recorded music is recorded in the storage 4, the compact disc 3 can be easily identified and reproduced from other music by using the variable data.

As the additional information, address data of a highlight portion, which is the most characteristic portion of the music, is assigned. The compact disc 3 is designed so that it is possible to easily determine whether or not the music is the desired music by listening to the highlighted portion on the basis of the address data of the highlighted portion.

On the other hand, the audio signal SA from the external device is based on, for example, music distribution via the Internet or music distribution via digital satellite broadcasting.
In the audio signal SA, additional information is similarly allocated and provided. Thus, in an Internet server or a digital satellite broadcasting station for distributing such music, these pieces of additional information are assigned to each music and distributed.

In the audio system 1, an audio interface (audio 1 / F) 5 acquires an audio signal SA and additional information from an external device, and records them in a storage 4 via an arithmetic processing unit 6. The audio interface 5 drives the speaker 7 with the audio signal SA, and instead drives the speaker 7 with an audio signal output from the changer 2 or an audio signal reproduced in the storage 4.

The storage 4 records the audio signal SA input from the audio interface 5 and the audio signal input from the changer 2 under the control of the arithmetic processing unit 6, and outputs the recorded audio signal to the audio interface 5.

Then, the process proceeds to step SP2, where the additional information is read from the storage 4 for all the music recorded in the storage 4. Subsequently, the processing unit 6 proceeds to step SP3,
Variable data is extracted from the additional information. Subsequently, in step SP4, the arithmetic processing unit 6 converts the extracted variables into coordinate values in a predetermined coordinate space.

Here, the arithmetic processing section 6 displays the menu screen shown in FIG. 4 according to the processing procedure shown in FIG.
Here, this menu screen forms a menu screen for music selection by displaying characteristics of music recorded in the storage 4 in a coordinate space in which variable data is used as coordinate axes. In FIG. 4, according to the setting of the user,
Set the coordinate axes of the loudness value, tempo value, and brightness value to 3
The x, y, and z coordinate axes in the dimensional space are set, and each music is indicated by a point in the coordinate space.

The arithmetic processing section 6 generates the coordinate values in the three-dimensional space by the processing in step SP4.

In parallel with the conversion of the coordinate values in the coordinate space, the arithmetic processing unit 6 proceeds from step SP1 to step SP5, fetches the coordinate values in the coordinate space set by the user, and sets the coordinate axes. . That is, in this embodiment, the range in this coordinate space is sequentially narrowed down by the user's operation, and the viewpoint is moved. The features of each music are displayed in a two-dimensional coordinate space. In step SP5, the arithmetic processing unit 6 forms a coordinate space so as to correspond to the display mode selected by the user from these display modes.

Subsequently, in step SP6, the arithmetic processing section 6 maps each point to the coordinate space thus formed in accordance with the coordinate values generated in step SP4, and thereby places each music in this coordinate space. Are combined on the display screen. Arithmetic processing unit 6
Drives the display driver 8 to display the display screen on the display device 9 in the following step SP7, and then proceeds to step SP8 to end the processing procedure.
As a result, as shown in FIG. 4, the arithmetic processing unit 6 displays the characteristics of the music recorded in the storage 4 in a coordinate space using the variable data as the coordinate axes. At this time, the arithmetic processing unit 6 displays the music title of the music represented by each point in the vicinity of the corresponding point according to the setting of the user.

The arithmetic processing unit 6 reproduces the music recorded in the storage 4 according to the user's selection operation on the display screen thus formed and provides the music to the user. That is, as shown in FIG. 5, the arithmetic processing unit 6 sends the pointing device 1 from the pointing driver 10.
When the operation 1 is notified, the process proceeds from step SP11 to step SP12, where the input of the pointing device is detected. Subsequently, the arithmetic processing unit 6 proceeds to step SP1
Then, the process proceeds to step SP13, where after the coordinate value designated by the pointing device 11 is detected, the process proceeds to step SP13, where a search is made for a corresponding song name from the detected coordinate value.

Subsequently, the arithmetic processing unit 6 proceeds to step SP15
Then, for the searched song name, the storage 4 is accessed to reproduce the song highlight portion, and when the user selects the confirmation menu, the process proceeds to step SP16 where the storage device 4 instructs the storage 4 to play the corresponding music. Then, the process proceeds to step SP17, and this processing procedure ends.

To display the characteristics of each music (FIG. 6). As a result, in the audio system 1, it is possible to present the characteristics of each music to the user by a map-like display, and to select the desired music more intuitively.

If necessary, the range in this coordinate space is sequentially narrowed down by the user's operation, the viewpoint is moved, and instead of the three-dimensional coordinate space, two of these three variables are used. The characteristic of each music is displayed in the two-dimensional coordinate space according to the above, so that it is possible to select a desired music without, for example, confirming the title of the music.

That is, by narrowing down the range in the coordinate space and displaying the characteristics of the music, music that gives an impression similar to the desired music is roughly selected from many musics, and then the desired music is selected. can do.
Further, by moving the viewpoint and displaying the music, for example, even when a large number of music pieces having the same tempo are recorded, it is possible to select the desired music by shifting the brightness and the noise to the center of the selection criterion. Also, instead of three-dimensional coordinate space,
The characteristic of each music is displayed in a two-dimensional coordinate space based on two of the two variables, and similarly, for example, even when a large number of songs having the same tempo are recorded, brightness and noise are selected. To select the desired music.
