In FIG. 1, reference numeral 1 denotes a CD player with a disc changer. The CD player 1 with a disc changer is provided with a disc storage door 2 which can be opened and closed freely. In the disk storage door 2, a so-called CD-TEXT compact disk in which text information is recorded in the TOC area is stored, for example, up to 200 sheets. A desired disc is selected from these discs and reproduced by the CD player 1 with a disc changer. This reproduced output is supplied to the speakers 5a and 5b, and the reproduced sound of the disc is output from the speakers 5a and 5b.

A display 4 is provided on the CD player 1 with a disc changer. This display 4
Displays a text based on the CD-TEXT information stored in the CD player 1 with a disc changer. As will be described later, the information recorded on the CD-TEXT disc includes information such as the name of the seller of the disc, the POS code, and the year of release (release year, month, and date). In the CD player 1 with a disc changer to which the present invention is applied, a desired disc is searched for from a plurality of discs stored in the CD player 1 with a disc changer based on the information of the release year and reproduced. , The playback order can be determined.

FIG. 2 shows the structure of a compact disc reproduced by the CD player 1 with a disc changer. As shown in FIG.
Reference numeral 1 designates a lead-in area 103, which is a program management area in which TOC data is recorded, a program area 104 in which program data is recorded, a program area 104 in which program data is recorded, An area, a so-called lead-out area 105, is formed. In a compact disc for audio reproduction in which audio information is recorded, audio data is recorded in a program area 104, and time information of the audio data is managed in a lead-in area 103.

On the compact disk, subcodes are recorded in addition to audio data as main data. An audio signal recorded on a compact disc is 16 bits in one sample or word, and
It is sampled at a sampling frequency of 4.1 kHz. The sampled data is obtained by dividing one sample or 16 bits of one word into upper 8 bits and lower 8 bits to form a symbol. Each symbol is subjected to an error correction coding process or an interleave process, and the audio data is processed. Every 24 symbols are combined into one frame. One frame corresponds to each of six samples of the left and right stereo channels.

EFM modulation converts 8 bits of each symbol into 14 bits. FIG. 3 shows the data structure of one frame after the EFM modulation. One frame 135 is 24
A synchronization pattern data area 131 of channel bits;
A subcode area 132 of 14 channel bits, 12
A program data area 133 including symbol program data D1 to D12, a parity data area 134 including four symbol parity data P1 to P4,
It comprises another program data area 133 and a parity data area 134. In order to connect each area or data part, a connection bit of three channel bits is allocated to each part. Therefore, one frame 13
5 includes a total of 588 channel bits of data.

FIG. 4 shows 98 frames collected and rearranged so that each area and data portion of this frame 135 are vertically continuous. The cycle of 98 frames shown in FIG. 4 is a unit for completing a subcode, and is called a subcode frame. This sub-code frame has a frame synchronization pattern section 136.
, Subcode section 137, data and parity section 1

lation: EFM) out of rule
It is a pattern of. Further, each of the 8 bits of one symbol constitutes the P channel to the W channel of the subcode. For example, the P channel is S0,
It is composed of a part of S1 and P01 to P96.

The P channel of the subcode has information corresponding to the presence or absence of a program, and the Q channel has absolute time information on a compact disc, time information of each program, and a program number (also referred to as a track number). ,
Information such as a movement number (also referred to as an index) is included. Therefore, according to the information included in the Q channel,
It is possible to control the playback operation such as the beginning of the program,
Further, by displaying the information of the Q channel, it is possible to visually confirm the number of the program being played on the optical disk, the elapsed time of the performance, the absolute time from the beginning, and the like.

Further, the subcode R channel W
Data for six channels up to the channel is prepared. A method of recording additional character information on a compact disc using the R to W channels in the lead-in area is CD-TEXT. In the case of CD-TEXT,
Character information of about 6,500 characters can be recorded, and the additional character information of the compact disc is 800 characters or less, and is adapted to languages of eight countries.

6 is stored. The controller 70 receives an input from the operation unit 81. The character information stored in the CD-TEXT memory 76 is displayed on the display unit 82 (corresponding to the display 4).

As described above, in the CD player with a disc changer to which the present invention is applied, a desired disc is selected from a plurality of discs stored in the CD player with a disc changer based on the information of the release year. You can search and play, or determine the order of playback. Of course, it is also possible to search for a desired disc from a plurality of discs stored in the CD player 1 with a disc changer, and not to reproduce only that disc.

For example, to search for and play back a disc released in 1969, the release year key 201 is pressed as shown in FIG. 30A. When the release year key 201 is pressed, first, the default value of the release year (for example, 1
996).

Then, as shown in FIG. 29B, the up keys 202a and 202b are operated, and the desired release year,
For example, it is set to 1969. When the desired release year is set, the setting key 203 is pressed as shown in FIG. 29C. When the setting key 203 is pressed, the release year information of the disc (the disc ID (86 shown in FIGS. 21 and 22)
h)), the disc for the desired release year, for example, 1969, is searched and displayed on the display. The display first shows one disc of the desired release year. Then, the up keys 202a and 2
When 02b is pressed, discs of a desired release year that match the search conditions are further searched, and these are sequentially displayed. When the desired disc is determined, the play key 205 is pressed as shown in FIG. 30D. When the play key 205 is pressed,
Playback of the disc is started. When the stop key 204 is pressed, the reproduction operation is stopped.

FIG. 31 is a flowchart showing the processing at this time. In FIG. 31, it is determined whether or not the release year key has been pressed (step ST1). When the release year key has been pressed, the variable y indicating the search year is set to a default value (step ST2).

It is determined whether the up key has been pressed (step ST3). If the up key has been pressed,
The variable y indicating the search year is incremented (step ST4). If the up key has not been pressed, it is determined whether or not the down key has been pressed (step ST5). If the down key has been pressed, the variable y indicating the search year is decremented (step ST6). Then, it is determined whether or not the enter key has been pressed (step ST7). If the up key and the down key have not been pressed, or if the enter key has not been pressed, the process returns to step ST3.

When the enter key is pressed, the search year y is substituted for the variable x (step ST8). Then, the first disk of the disk whose search year is x is searched, and that disk is displayed (step ST9).

It is determined whether or not the up key has been pressed (step ST10). If the up key has been pressed, the disk next to the year x is displayed (step ST1).
1). If the up key has not been pressed, it is determined whether or not the down key has been pressed (step ST12). If the down key has been pressed, the disk before y years is displayed (step ST13). Then, it is determined whether or not the reproduction key has been pressed (step ST14). If the up key and the down key have not been pressed, or if the reproduction key has not been pressed, the process returns to step ST10.

When the play key is pressed, the disc specified at that time is accessed, and the disc is reproduced (step ST15).

In the above-described example, the search is performed by designating the release year. Similarly, the search may be performed by designating the range of the release year. Further, it is also possible to perform a search by designating a release year or a range of a release year, and not to reproduce only the searched disc.

Further, in the above-described example, the disc is searched by specifying the release year. However, the discs may be sorted and played back in the order of the release year. FIGS. 32 and 33 are flowcharts in the case where a range of release years is designated and discs are sorted and played back in the order of release years within the range of release years.

In FIGS. 32 and 33, it is determined whether or not the release year key has been pressed (step ST21). When the release year key has been pressed, the variable y indicating the search start year is set to a default value (step ST21). ST22).

It is determined whether or not the up key has been pressed (step ST23). If the up key has been pressed, the variable y indicating the search start year is incremented (step ST24). If the up key has not been pressed, it is determined whether or not the down key has been pressed (step ST25). If the down key has been pressed, the variable y indicating the search start year is decremented (step ST2).
6). Then, it is determined whether or not the start determination key has been pressed (step ST27). If the up key and the down key have not been pressed, or if the start determination key has not been pressed, the process returns to step ST23.

When the start decision key is pressed, a variable z indicating the search end year is set to a default value (step ST).
28). It is determined whether or not the up key has been pressed (step ST29). If the up key has been pressed, the variable z indicating the search end year is incremented (step ST30). If the up key has not been pressed, it is determined whether the down key has been pressed (step ST3).
1) If the down key is pressed, the variable z indicating the search end year is decremented (step ST32). Then, it is determined whether or not the end determination key has been pressed (step ST33). If the up key and the down key have not been pressed, or if the end determination key has not been pressed, the process returns to step ST29.

When the end determination key is pressed, a variable y indicating the search start year is substituted for a variable x (step ST3).
4). Then, the first disk whose release year is x years is searched, and the disk is displayed (step ST35).

It is determined whether or not the play key has been pressed (step ST36).
The year disc is reproduced (step ST37). It is determined whether or not all the disks with the release year x have been reproduced (step ST38), and the reproduction of the disk is continued until the reproduction of all the disks with the release year x is completed.

When the reproduction of the disk with the release year x is completed, the release year x is incremented (step ST3).
9) It is determined whether the release year x has exceeded the search end year z (step ST40). If the release year x does not exceed the search end year z, the process returns to step ST37, and the disc of the next release year is reproduced.

If it is determined in step ST40 that the release year x has exceeded the search end year z, it is determined that the reproduction up to the release year z has been completed and the reproduction is terminated (step ST4).
1). In the above-described example, the release year information is recorded on the disc, but the announcement year of the disc may be recorded. For example, in the case of a reprint or the like, the date when the disc was first announced and the year when the disc was released are different. In such a case, the date when the disc was first announced may be recorded, or both the release year and the release date may be recorded.

Further, for each music stored in each disk, the release year or announcement year of the music may be recorded. In this way, it is possible to perform a search by date or to sort and play back each song in chronological order.
