[0002]

2. Description of the Related Art Using a CD-TEXT, a CD with a disc changer capable of retrieving and reproducing a desired disc from a large number of stored discs.
Player development is underway. In addition, CD-TEX
T records character information related to the disc using the subcode R to W channels of the lead-in area of the compact disc.

In a CD player with a disc changer capable of using such a CD-TXT, a decoder for decoding character information recorded on a disk and a memory for storing the character information are provided in the player body. When a CD-TEXT disc is mounted on a CD player, the TOC (Table Of C
On-tents) data is read from the CD-TEXT area, and this data is decoded and stored in the memory.
Then, if necessary, this character information is displayed on the display of the player body. As a result, the user can know the information of the stored disc, such as the album title, the artist name, and the title of the song, from the display on the display.

[0004]

As described above, the CD-T
In a CD player with a disc changer that can use EXT, information such as a disc title and an artist name can be displayed on a display as needed. Therefore, by using such character information, a desired disc can be easily searched from a plurality of discs stored in a CD player with a disc changer.

However, in a conventional CD player with a disc changer that can use CD-TEXT, a memory for storing character information, a display for displaying character information, and the like are provided in the player body. Therefore, C
Text information obtained from the D-TEXT is displayed on a display on the main body side of the CD player. Therefore, when performing an operation at hand using a remote commander, the user must look at the display on the main body of the CD player, and the remote commander uses the remote commander to display the album name, artist name, and song name obtained from the CD-TEXT information. There is a problem that it is not easy to select and play a desired disc or music using character information.

[0006] It has also been proposed to use kanji for CD-TEXT character information. In the case of displaying kanji, a kanji ROM is required.
In a conventional CD player with a disc changer that can use CD-TEXT, a memory for storing character information, a display for displaying character information, and the like are provided in the player body. For this reason, in the case where the kanji display can be performed, it is necessary to provide a kanji ROM on the player body side. However, when a kanji ROM is provided on the player main body side, if there are a plurality of disc players that can use CD-TEXT, it is necessary to prepare a kanji ROM for each device, which leads to an increase in cost. Become.

Is operated by the remote commander 3. The remote commander 3 is provided with a display 4. The remote commander 3 can exchange data with the CD player 1 with a disc changer using infrared communication.

On the display 4, a touch panel is mounted. The display 4 has a CD-TEX stored in the CD player 1 with a disc changer.
A text based on the T information is displayed. The user can make an input while watching the text display on the display 4.

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
38. This one sub-code frame is
This is equivalent to 1/75 second of the playback time of a compact disc.

Here, the subcode data including the data of the P channel and the Q channel is data recorded in the subcode section 137 in FIG. FIG. 5 shows the details of the data structure of the subcode frame of the subcode unit 137. The first frame F01 and the frame F02 are the subcode frame synchronization pattern S0,

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.
