DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 10 denotes a personal computer. The personal computer 10 has a built-in CD-ROM drive 11, a floppy disk drive 12, and the like.
A keyboard 13 and a mouse 14 are connected. Further, a CD-RW drive 15 and a color CRT display 16 are connected to the personal computer 10 via a SCSI interface.

In FIG. 1, reference numeral 20 denotes a CD player mounted on an automobile, and a CD insertion slot 21, a display 22, and various operation buttons 23 are provided on a front surface thereof. In this case, the display 22 is constituted by, for example, an LCD having a backlight, and displays characters (including numbers and symbols; the same applies hereinafter) by a combination of dots, and displays a track number, a reproduction time, a custom time by a combination of the characters. It displays characters and the like in a file.

When the personal computer 10 executes a program dedicated to a custom file, a custom file is created. That is, when the keyboard 13 or the mouse 14 of the personal computer 10 is operated to start the dedicated program,
An initial screen is displayed on the display 16, and a message prompting the user to set a CD for which a custom file is to be created is displayed.

Therefore, a CD 31 in which music or the like is recorded and for which a custom file is to be created is set in the CD-ROM drive 11, and this is notified to the program by operating the keyboard 13 or the mouse 14. Then
In the personal computer 10, the information of the TOC is read from the CD 31 and temporarily stored in the memory.

Subsequently, the personal computer 10
You can enter the disc name and song name displayed by the custom file.
6 is displayed. Therefore, the user inputs data such as the disc name and the song name from the keyboard 13 or, in some cases, by operating the mouse 14. This data input can be performed almost in the same manner as a general word processor, but is made to be input to the disk 31 and each track thereof. The data thus input is also temporarily stored in the memory of the personal computer 10.

As described above, the user inputs a disc name, a song name, and the like. When the input is completed, the keyboard 13 or the mouse 14 is operated to notify the program. Then, a message prompting to set the CD-RW 32 in the CD-RW drive 14 is displayed on the display 16. Therefore, the CD-RW 32 is set in the CD-RW drive 14 according to this message, and the keyboard 13 or the mouse 14 is operated to instruct the continuation of the processing.

Then, the TO once stored in the memory
The information of C and the key input data such as the disc name and song name are shaped into the data format of the custom file, and an identification code indicating that the following data is the data of the custom file is added at the beginning, for example. And
The data to which the shaping and the identification code are added are written to the CD-RW 32 with a predetermined file name.

When the writing is completed, a message for displaying the CD-RW 32 on the CD player is displayed on the display 16, and the program of the personal computer 10 is terminated.

Therefore, the CD-RW32 is replaced with a CD-R
It is taken out from the W drive 15 and set on the CD player 20, and the reproduction button of the operation buttons 23 is pressed. Then, in the CD player 20, the reproduction of the CD-RW 32 is started, the TOC information of the CD-RW 32 is read, and the TOC information includes a file (track) having a file name indicating a custom file. It is checked whether it is.

In this case, since there is a file having such a file name, the file is read out,
The identification code in that file is checked. In this case, since the identification code indicates that the file is data of a custom file, the data of the custom file is stored in the non-volatile memory of the CD player 20 in the area of the custom file. Is written to.

When the data of the custom file of the CD 31 is stored in the CD player 20 in this manner,
At the time of reproduction of the CD 31, a disc name, a song name, and the like are displayed on the display 22 according to the data of the custom file. That is, when the CD 31 is set in the CD player 20 and the reproduction is instructed by the operation button 23, the CD 31
Using the TOC information read from the CD as a search word, the data of the custom file is searched, and the disc name, song name, and the like are displayed on the display 22 by the data that matches the TOC information of the CD.

Thus, the CD player 20 stores the CD3
One custom file is registered. In this case, the user can input data of the custom file using the personal computer 10 at home or the like.
There is no need to type in the car.

Although the CD player 20 is mounted on the car, the registration of the custom file can be completed only by setting the CD-RW 32 to which data has been input by the personal computer 10 into the CD player 20.

Further, since the work time in a car is greatly reduced, a large number of data such as artist names, artist information, music information, memos, etc., which have conventionally been difficult to register, must be registered. And the data can be displayed in the car.

Further, since the data input by the user is performed by the personal computer 10, various data which can be handled by the personal computer can be input. For example, kanji and kana can be used for a song name and an artist name, and various displays can be performed depending on the function of the CD player. Furthermore, even for a CD that does not support CD-TEXT, an information display function equivalent to CD-TEXT can be used.

In the example shown in FIG. 2, the CD player is a CD changer. And in this case,
A CD changer body 41 is provided in a trunk room of a car or the like, and an operation unit (CD changer controller) 4 is provided.
4 is provided on a dashboard of a car or the like. Then, the CD-RW 32 in which the custom file is written as in the case of FIG. 1 is set in the magazine 42 of the CD changer main body 41 and is loaded into the CD changer main body 41.

When the same operation as in FIG. 1 is performed from the operation unit 44, the data of the custom filter is read from the CD-RW 32 and stored in the CD changer main body 41. When playing a CD, the CD changer body 4
Of the data of the custom file stored in 1,
The corresponding data is transmitted to the operation unit 44 through the communication cable 43.
Is displayed on the display 45 of the operation unit 44.

Therefore, in the case of FIG.
The same effect as in the case of FIG. 1 can be obtained.

In the example shown in FIG. 3, the CD player 2
0 is remote control (remote operation) by infrared transmitter 17
If you can. That is, in this case, when the data of the custom file is input, the personal computer 1
0, for example, the transmitter 17 through an RS-232 cable.
Is connected. When the input of the custom filter data is completed in the same manner as in the case of FIG. 1, the data is sent to the transmitter 17 and stored in the transmitter 17.

Next, the transmitter 17 is connected to the CD player 2.
When a predetermined key operation is performed on the infrared receiver 24 of the remote controller 0, the data of the custom filter stored in the transmitter 17 is converted to infrared and transmitted. Then, the transmitted infrared light is received by the light receiving unit 24, the data of the custom file is extracted, and the data is stored in the CD player 20.

The transfer of data from the personal computer 10 to the transmitter 17 takes time,
Since it is difficult to transfer a large amount of data from the transmitter 17 to the CD player 20 at one time, in the case of this example, the above process is divided and executed several times.

In the example shown in FIG. 4, as in the case of FIG. 2, the data of the custom file is stored in the main body 41 of the CD changer, and the input thereof is the same as in the case of FIG. 17 is performed. In this case, the infrared ray from the transmitter 17 is received by the light receiving section 46 of the operation section 44 to extract the data of the custom filter, and this data is transferred to the CD changer main body 41 through the cable 43 and stored. .

By the way, in the custom file function of the current CD player, the data is limited to only the disc name, and the data is written to the CD player only when the target CD is set. Have been.

Therefore, in the example shown in FIG. 3 or FIG. 4, the following is also possible. That is, the data of the custom file includes only the CD name, and a plurality of the data are input to the personal computer 10 and transferred to the transmitter 17. Then, the data is transmitted to the transmitter 17.
Is transferred to the CD player 20, or
The data is transferred to the D changer main body 41, and when the CD is reproduced, the disc name is displayed by the corresponding data.

Accordingly, the amount of data per CD is reduced, so that the number of CDs to which the transmitter 17 can transfer data at one time can be increased, and the data of the CD player 20 and the CD changer main body 41 can be increased. The storage memory capacity can be reduced.
Also, only one transfer is required for one CD.

Further, in the examples of FIGS. 1 and 2,
Although the CD-RW 32 is used to transfer the data of the custom file, instead of the CD-RW 32, if the disc is compatible with the CD and can be reproduced by the CD player 10, the disc may be a CD-R, PD, or the like. You can also.

[0036]

According to the present invention, data of a custom file can be input by a personal computer at home or the like, and it is not necessary to input the data in a car. In addition, the registration of the custom file can be completed only by setting the disk into which data is input by the personal computer in the CD player.

Further, data which has conventionally been difficult to register can be registered, and the data can be displayed in a car. Further, since the data input by the user is performed by the personal computer, various data that can be handled by the personal computer can be used, so that various displays can be performed. In addition, CD
-Even if the CD does not support TEXT, the CD-T
An information display function equivalent to EXT can be used.
