[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device suitable for displaying various kinds of information on a reproducing device or the like.

[0002]

2. Description of the Related Art In recent years, CDs (compact discs) and M
2. Description of the Related Art Disk media such as D (mini-disc) have become widespread and are used for recording various data including music. In a mini-disc on which a user can freely record music and the like, not only audio but also additional information such as character information can be recorded. For example, a user can input a disc name or a track name, thereby recording an album title or a song name.

Further, in a medium called a CD text which is currently under development, character information and the like are recorded as text data in a predetermined area on a so-called CD-type disc. For example, the disc title, song title, performer, lyricist, Composers can be recorded.

[0004] In a reproducing apparatus corresponding to these media, a small-sized display device is provided so as to display a song title, a disc title, time information, and the like during reproduction.

[0005]

By the way, as character information, a track name (song name) and a disc name (disc title) are representative display information as described above, but a display device is relatively small. In many cases, the character display area on the display screen cannot be too large. In general, the display device of an MD player can display a character string for one line in many cases, and can display either a track name or a disc name. Each name was displayed.

[0006] In this case, when the user wants to obtain character information such as a disc title, a song title, a performer, a lyricist, a composer, etc., he or she looks at only one of the currently displayed track name or disc name. Can not. When the user wants to see other character information, he has no choice but to switch the display and check the character information. That is, the user
Two or more types of character information recorded on the recording medium could not be checked at a time, and it was troublesome to check the character information of a CD or MD. In order to solve this, it is conceivable to display a plurality of character information at the same time.However, a plurality of character strings complicates the display content and the user can understand what each character information displayed means. There was a problem that it was difficult to understand whether there was.

[0007]

In view of the above, the present invention has been made in view of the above, and when displaying additional character information such as a disc name and a track name, a plurality of character information can be displayed at the same time, and the display contents can be viewed at a glance. The purpose is to allow the user to easily recognize what corresponds to the above.

For this reason, in the display device, a display means capable of displaying and outputting the display information, an operation means for switching the display information, and controlling the display operation in accordance with the operation of the operation means. Control means is provided. The control means simultaneously displays two types of character information of the first character information and the second character information in different sizes in the display area among various kinds of display information to be displayed, and responds to the operation of the operation means. Thus, the magnitude relationship between the display sizes of the first character information and the second character information can be changed.

At this time, the first character information is additional information given to the recording medium, and the second character information is additional information given to each program recorded on the recording medium.

Alternatively, the first character information is the first additional information given to each program recorded on the recording medium, and the second character information is the first additional information given to each program recorded on the recording medium. The given second additional information is used.

That is, on the display device of the MD player, character information such as a disc name and a track name can be displayed at the same time. The other is displayed in a small size so that the user can determine the contents of each character at a glance. Further, the size of the character is switched according to the user's request or the like.

1. FIG. 1 shows a block diagram of a main part of a mini-disc reproducing apparatus provided with the first display device. This mini-disc reproducing apparatus includes a plurality of discs (mini-disc: recordable / reproducible magneto-optical disc or read-only optical disc)
ＤDn are stored and can be selectively reproduced.

Disk D on which audio data is recorded
Is driven to rotate by a spindle motor 2. The optical head 3 irradiates the disk D with laser light during reproduction.

The optical head 3 detects data from reflected light by a magnetic Kerr effect of a magnetic field pit for a magneto-optical disk, and detects data from a reflected light amount changed by an emboss pit for a read-only optical disk. Is detected. Therefore, the optical head 3 is equipped with a laser diode as a laser output unit, an optical system including a polarizing beam splitter and an objective lens, and a detector for detecting reflected light. The objective lens 3a is held by the biaxial mechanism 4 so as to be displaceable in the radial direction of the disk and in the direction of coming into contact with and separating from the disk. Optical head 3
The whole can be moved in the disk radial direction by a sled mechanism 5.

The information detected from the disk D by the optical head 3 by the reproducing operation is supplied to the RF amplifier 7. The RF amplifier 7 performs an arithmetic operation on the supplied information,
A reproduction RF signal, a tracking error signal, a focus error signal, groove information (absolute position information recorded as a pre-groove (wobbling groove) on the magneto-optical disk D) and the like are extracted. The extracted reproduced RF signal is supplied to the decoder section 8. The tracking error signal and the focus error signal are supplied to a servo circuit 9, and the groove information is supplied to an address decoder 10.

The servo circuit 9 performs various types of servo driving based on the supplied tracking error signal, focus error signal, track jump command and access command from the system controller 11 composed of a microcomputer, rotation speed detection information of the spindle motor 2, and the like. A signal is generated to control the two-axis mechanism 4 and the sled mechanism 5 to perform focus and tracking control, and to control the spindle motor 2 to a constant linear velocity (CLV).

The address decoder 10 decodes the supplied groove information to extract address information and a groove clock. Address information is stored in the system controller 11
And used for various control operations. Playback R
For the F signal, the decoder unit 8 performs EFM demodulation,
Decoding processing such as IRC is performed. At this time, addresses, subcodes, and the like included in the reproduced RF signal are also extracted as data and supplied to the system controller 11.

The audio data (sector data) decoded by EFM demodulation, CIRC or the like by the decoder unit 8 is
Buffer memory 1 once by memory controller 12
3 is written. The reading of data from the disk D by the optical head 3 and the transfer of reproduced data in the system from the optical head 3 to the buffer memory 13 are 1.41.
It is performed at Mbit / sec and usually intermittently.

The data written in the buffer memory 13 is read out at a timing when the transfer of the reproduction data becomes 0.3 Mbit / sec, and is supplied to the decoder unit 14. Then, the signal is subjected to reproduction signal processing such as decoding processing for the audio compression processing in the decoder section 14, converted into an analog signal by the D / A converter 15, supplied from the output terminal 16 to a predetermined amplifier circuit section, and reproduced and output. For example, they are output as L, R analog audio signals.

The disk D thus reproduced is stored in the disk changer 21. The disc changer 21 can store a plurality of discs D (D _{1 to} D _n ) and selectively load them on a disc table. Therefore, the disks D _{1 to} D _n are stored as the storage unit 22, and the disk D in the storage unit 22 is selected and loaded (and unloaded) on the disk table (the reproduction position by the optical head 3). A transport mechanism 23 is provided. The disc exchange operation by the disc transport mechanism 23 is controlled by the changer controller 24.

The changer controller 24 is connected to the system controller 11, and the system controller 1
A predetermined disk is selected from the storage section 21 according to the disk exchange information from 1 and transported by the transport mechanism 23,
Perform loading and unloading operations.
Each disk has 1 to n according to the storage position in the storage section 22.
For example, when the user performs the reproducing operation of the disc number 2, the changer controller 24 loads the disc D ₂ stored in the second position in the storing section 22 and reproduces it. Become.

The operation unit 19 is provided with various keys used for user operations. For example, a reproduction key, a stop key, an AMS key, a fast-forward key, a fast-reverse key, and the like are provided, and their operation information is supplied to the system controller 11. Moreover, and disk selection key for selecting the disc to be reproduced for a plurality of discs D ₁ to D _n, the program reproduction to program the reproduction order of the disc, repeat play to repeatedly play the disc or a specific track, a disc or track Operation keys and the like for special reproduction such as shuffle reproduction for selecting and reproducing in a random order are also provided.

The display unit 20 is constituted by, for example, a liquid crystal full dot color display, and performs an operation of displaying an operation state, a disc number, a track number, time information, a disc name, a track name, and the like based on the control of the display controller 17. . The display controller 17 receives various display information from the system controller 11 and performs an operation of displaying the display information on the display unit 20 based on the display mode control from the system controller 11.

In order to display characters on the display unit 20,
Character font 18 storing dot patterns of various characters
When display information (for example, an ASCII code) for character display is supplied from the system controller 11, the display controller 17 controls display on the display unit 20 based on the dot pattern in the character font 18. Do.

The system controller 11 acquires information obtained from the current operation mode, reproduction address, and TOC information described later, that is, the disc number being reproduced, the track number being reproduced, reproduction time information, and character information such as a disc name and a track name. , Recording date and time information are sequentially supplied to the display controller 17 as display information. As a result, the reproduction operation state, the disc number, the track number, the time information, the disc name, the track name, and the like are displayed on the display unit 20 while being updated as necessary.

The contents displayed on the display unit 20 are switched according to the display mode. An operation key (display mode key) for switching the display mode is provided in the operation unit 19, and the user can arbitrarily switch the display mode. In this example, it is assumed that a character display mode in which a disc name and a track name are simultaneously displayed as additional information such as characters and a recording date and time display mode in which a recording date and time is displayed can be switched by operating a display mode key. . The display mode may be switched according to the operation of the display mode key, or the system controller 11 may automatically switch according to the operation state. In addition, regarding the display of the time information according to the operation of the display mode key, the time of the music, the total progress time, the total remaining time, the remaining time, and the like can be displayed.

Further, as will be described in detail later, in this example, a plurality of character strings are displayed in different sizes in the character display mode, and the size relationship between the character strings can be switched according to a user operation. Like that. For this purpose, the operation unit 19 is provided with a replacement key.

The display section 20 is a full dot color display. As is already known, a full-dot color display corresponds to each pixel (dot) with R,
G, B 3 primary color pixels are prepared, and R / G /
By controlling the light emission ratio of B, an arbitrary color can be displayed for each pixel. Therefore, under the control of the system controller 11, the display unit 20 can display the display content to some extent freely and in any color using the display area.

When a reproducing operation is performed on the disk D, management information recorded on the disk D, that is, P-TOC (premastered TOC), U-TOC
(User TOC) must be read. The system controller 11 responds to the management information by
The address of the area to be reproduced is determined. This management information is held in the buffer memory 13.
Therefore, in the buffer memory 13, a buffer area for the reproduction data as described above and an area for holding these management information are divided and set. Then, the system controller 11 reads out the management information by executing the reproduction operation on the innermost peripheral side of the disk on which the management information is recorded when the disk D is loaded, and stores the information in the buffer memory 13. Thereafter, it can be referred to at the time of the reproducing operation for the disc D.

Since it is a changer type,
For example, the discs D1 to Dn stored in a period in which reproduction is not performed may be sequentially loaded, and necessary TOC information may be read from each disc D. In this case, in order to prevent data loss even when the power is turned off, it is preferable to provide a non-volatile RAM, an S-RAM having a power backup configuration, and hold the TOC data of each disk. It is.

2. U-TOC Sector Here, the U-TOC sector will be described as management information for managing the reproduction operation of a track (music or the like) on the disk D. In addition, U-
The TOC and the P-TOC are provided.
C is formed in the innermost pit area of the disk 1 and is read-only information. The P-TOC manages the position of a recordable area (recordable user area), a lead-out area, a U-TOC area, and the like on the disc. In the mini disc system, a read-only optical disc (pre-mastered disc) in which all data is recorded in pit form
Can be used, but for premastered discs, P
The music recorded in the ROM by the -TOC can also be managed, and the U-TOC is not formed. A detailed description of the P-TOC is omitted, and here, the U-
-TOC will be described.

FIG. 4 shows the format of U-TOC sector 0. In addition, as the U-TOC sector, sector 0 to sector 7 can be provided,
Sectors 1 and 4 are character information, and sector 2 is an area for recording the recording date and time.

The U-TOC sector 0 is a data area in which management information on a song (track) recorded by the user and a free area in which a new song can be recorded is mainly recorded. For example, the system controller 11
Discriminates an area in which a track to be reproduced is recorded from the U-TOC sector 0 during reproduction, accesses the area, and performs a reproducing operation.

The data area (4 bytes × 588, 2352 bytes) of the U-TOC sector 0 has all 0s at the head position.
Alternatively, a synchronization pattern in which all 1-byte data are formed side by side is recorded. Then the cluster address (Clust
er H) (Cluster L) and an address to be a sector address (Sector) and mode information (MODE) are added by 4 bytes,
This is the header.

A sector is a data unit of 2352 bytes, and 36 sectors constitute one cluster. Regarding the synchronization pattern and address, this U-TOC sector 0
Not only that, but also a P-TOC sector and a data sector in which audio data is actually recorded are recorded on a sector basis. Next, the manufacturer code, model code, and track number (F
irst TNO), track number of last track (Last T
NO), data such as sector usage (Used sectors), disk serial number, and disk ID are recorded.

Further, in order to identify the area (free area) or the like of the track (music, etc.) recorded by the user by making it correspond to a management table section described later, various tables are used as a correspondence table instruction data section. Pointers (P-DFA, P-EMPTY, P-FRA, P-TNO1 to P-TN
O255) is recorded.

The table pointer (P-DFA to P-TNO25)
5) (01h)
There are provided 255 parts tables from (FFh) to (FFh). In each of the parts tables, a start address serving as a starting point, an end address serving as an end, and mode information (track mode) of the part are recorded. ing. In addition, since the parts indicated in each part table may be successively connected to other parts, link information indicating the part table in which the start address and the end address of the connected parts are recorded can be recorded. Have been. In the present specification, the numerical value with “h” is in a so-called hexadecimal notation. Further, a part refers to a track portion in which temporally continuous data is physically continuously recorded in one track.

In this type of recording / reproducing apparatus, even if data of one music piece is physically discontinuous, that is, even if it is recorded over a plurality of parts, it is reproduced while accessing between parts, so that the reproducing operation is hindered. Therefore, the music or the like recorded by the user may be recorded in a plurality of parts for the purpose of efficient use of the recordable area.

Therefore, link information is provided, and the part tables can be connected by designating the part tables to be connected, for example, by the numbers (01h) to (FFh) given to the respective part tables.
That is, in the management table section in the U-TOC sector 0, one part table represents one part. For example, for a track configured by connecting three parts, three parts connected by link information are used. The position of the part is managed by the table.

The parts tables from (01h) to (FFh) in the management table section of the U-TOC sector 0 are table pointers (P-DFA, P-EMPTY, P-FRA, P-TNO1 to P-TN).
O255) indicates the contents of the part as follows.

The table pointer P-DFA indicates a defective area on the magneto-optical disk D. One or a plurality of parts tables indicating a track portion (= part) serving as a defective area due to a scratch or the like is shown. The first part table in the box is specified. In other words, if there is a defective part, (01h) to
Either (FFh) is recorded, and the corresponding parts table indicates the defective part by the start and end addresses. If another defective part exists, another part table is designated as link information in the part table, and the defective part is also shown in the part table. If there is no other defective part, the link information is, for example, "(0
0h)]], and there is no link thereafter.

The table pointer P-EMPTY indicates the head part table of one or a plurality of unused part tables in the management table section. If there is an unused part table, the table pointer P-EMPTY is set as the table pointer P-EMPTY. , (01h) to (FFh) are recorded.
If there are multiple unused part tables, the part table specified by the table pointer P-EMPTY is sequentially specified by link information, and all unused part tables are connected on the management table section Is done.

The table pointer P-FRA indicates a free area (including an erasure area) on which data can be written on the magneto-optical disk D. One or a plurality of parts tables indicating parts to be free areas are shown. Of the first part table is specified. That is, if there is a free area, (01h) to (F
Fh) is recorded, and in the corresponding parts table, parts which are free areas are indicated by start and end addresses. When there are a plurality of such parts, that is, when there are a plurality of parts tables, the link information indicates "(00
h)] are sequentially specified up to the parts table.

FIG. 5 schematically shows the management state of parts which are free areas by using a parts table. This is because when the part (03h) (18h) (1Fh) (2Bh) (E3h) is set as a free area, this state follows the table pointer P-FRA and the parts table (03h) (18h) (1Fh) (2Bh) ) (E3h) indicates the state represented by the link. The above-described management of the defective area and the unused parts table is the same.

Table pointers P-TNO1 to P-TNO255 indicate tracks such as songs recorded on the magneto-optical disk D by the user.
In P-TNO1, a parts table indicating a temporally leading part of one or a plurality of parts on which data of the first track is recorded is designated. For example, the track set as the first track is not divided on the disc,
In other words, if recorded in one part, the first
The recording area of the track is recorded as a start and end address in the parts table indicated by the table pointer P-TNO1.

For example, when the music set as the second track is discretely recorded on a plurality of parts on the disc, each part is designated in order of time to indicate the recording position of the second track. Is done. In other words, from the part table specified by the table pointer P-TNO2, another part table is sequentially specified by the link information according to the temporal order, and linked to the part table in which the link information is "(00h)". (Same form as above, FIG. 5). In this way, for example, since all the parts on which the data constituting the second tune are recorded are sequentially designated and recorded, the data of the U-TOC sector 0 can be used to reproduce the second tune or the second tune. When performing overwrite recording on the area, it is possible to access the optical head 3 and the magnetic head 6 to extract continuous music information from discrete parts, and to perform recording using the recording area efficiently.

Next, FIG. 6 shows the format of the U-TOC sector 1. This sector is used as a data area for recording input character information when a track name or a disc name is given to each recorded track.

In the U-TOC sector 1, slot pointers P-TNA1 to P-TNA255 are prepared as character slot indication data portions corresponding to recorded tracks, and the slot pointers P-TNA1 to P-TNA255 are provided. Are prepared as slots (01h) to (FFh) in units of 8 bytes and 255 units, and manages character data in substantially the same manner as the U-TOC sector 0 described above.

In the slots (01h) to (FFh), character information as a disc title or a track name is recorded in ASCII code. The 8 bytes immediately before the slot (01h) are a dedicated area for the disc name. Then, for example, the character specified by the user corresponding to the first track is recorded in the slot specified by the slot pointer P-TNA1. Further, by linking the slots by the link information, the character input corresponding to one track can be handled even if it is larger than 7 bytes (7 characters). In this U-TOC sector 1, the slot pointer P-EMPTY manages an unused parts table.

A U-TOC sector 4 is provided as an area for recording character information. Similarly to sector 1, U-TOC sector 4 is a data area for recording input character information when a track name or disc name is given to a track on which the user has recorded, and the format is as shown in FIG. Illustration is omitted because it is almost the same. However, in this sector, code data corresponding to kanji and European characters are recorded. In addition to the data of sector 1 in FIG. 6, an attribute of a character code used as a character code is recorded at a predetermined byte position. . This management of the character information of the U-TOC sector 4 is performed in the same manner as in the sector 1 by using 255 units designated by the slot pointers P-TNA1 to P-TNA255 and the slot pointers P-TNA1 to P-TNA255 as the character slot indication data portion. This is performed by the slots (01h) to (FFh).

As described above, since the U-TOC data is recorded on the disk D, the system controller 11 displays the disk name and the track name read from the disk D on the display unit 20 together with the reproducing operation on the disk D. Can be done. Although the description is omitted, the U-TOC sector 2 is an area for recording the recording date and time.

3. Example of Display Operation of First Display Device An example of the display operation of the display device of the present example mounted on the playback device configured as shown in FIG. 1 will be described. The display device of the present example corresponds to a portion configured by the display unit 20, the display controller 17, the character font 18, the display control function of the system controller 11, and the display mode key in the operation unit 19.

In the present embodiment, the first character information and the second character information are simultaneously displayed in two columns for various information displayed on the display unit 20, and the display size is changed according to the operation of the user. Have to be able to.
For example, the character display size of the track name is displayed large and the character display size of the disc name is displayed small.

Here, the information on the entire disc D is a disc number, a disc name, and a recording date and time of the disc. The disc number is a number set according to the storage position of the storage unit 22 as described above.
The disc name and the disc recording date and time are information read from U-TOC sector 1 and sector 2 of the disc D.

The information on each track recorded on the disk D is a track number, a track name, and a track recording date and time. The track number is the track number in the disk D, that is, the U-TOC
The numbers correspond to the table pointers P-TNO1 to P-TNO255 of sector 0. The track name and track recording date and time are the U-TOC sector 1 and sector 2 of the disk D.
This is the information read from.

Based on such settings, the system controller 11 displays on the display unit 20, for example, FIG.
The display as shown in (b) is executed. As shown in FIG.
(B) is a display operation example during reproduction, for example.

In this case, the disc name display 34 and the track name display 35 are simultaneously performed together with the disc number display 31, the track number display 32 and the time information display 33. In FIG. 3A, the track name display 34 is displayed large and the disc name display 35 is displayed small. In FIG. 3B, the track name display 34 is made smaller and the disc name display 35 is made larger.

In this way, two character strings are displayed on the display, and the sizes are different in size, so that the user can easily distinguish the contents of the displayed characters. In this example, the size of the character information can be arbitrarily exchanged by operating the exchange key. The processing of the system controller 11 (and the display controller 17) for realizing such a display operation is, for example, as shown in FIG. 2, and the display operation will be described with reference to FIGS.

FIG. 3A shows a disc number display 31, a track number display 32, and a time information display 33, which is a reproduction progress time, in which the fifth stored disc D5 is loaded, and one of the fourth tracks D5 is loaded. It is displayed that the position at minute 23 seconds is being reproduced. For example, during reproduction of a certain track, the character display of the track name is enlarged and the character display of the disc name is reduced. That is, as shown in the figure, "MUSIC BOX" as the track name display 34 is displayed in large characters as the song name of the fourth track of the disk D5, and "MARIAHCAREY" as the disk name display 35 is displayed as a small title as the disk title of the disk D5. It is displayed in character display.

The processing of the system controller 11 at this time is the processing of steps F101 and F102 in FIG. That is, when the display operation is set to the character display mode by the user's operation or the program operation of the system controller 11, the process proceeds from step F101 to step F102, in which the character name for displaying the track name large and the disk name for small display is displayed. Let it run. Therefore, FIG.
Both names are displayed as shown in FIG. By knowing that the track name is usually displayed large, the user can see at a glance which character is the track name and which is the disc name. In addition, the track name displayed as a large size can be easily recognized at a glance.

In the display state as shown in FIG. 3A, the system controller 11 monitors the operation of the exchange key by the user in step F103, and performs the operation of the display mode key or the program operation by the user in step F104. Monitor the display mode change timing based on the display mode.
If the user operates the exchange key at this time, the process proceeds from step F103 to step F105.

In step F105, the system controller 11 checks the current display state of the character information. That is, it is checked which of the disc name and the track name is larger and which one is smaller. If the process proceeds to step F105 while the display of FIG. 3A is being performed by the process of step F102, it is determined that the track name is currently displayed in a large size and the disc name is displayed in a small size. Therefore, a positive result is obtained in step F105, and the process proceeds to step F106. Then, the track name is displayed in a small size, and the disc name is displayed in a large size. Therefore, the display state is as shown in FIG.

The process of the system controller 11 returns to the loop from step F106 to steps F103 and F104, and the system controller 11 monitors the operation of the exchange key and the change of the display mode. Here, if the user operates the exchange key again, the process proceeds to step F105. However, if the display state is as shown in FIG. 3B, a negative result is obtained in step F105. F102
Proceed to. Accordingly, the display returns to a state where the track name is displayed in a large size as shown in FIG.

Thereafter, the process returns to the loop of steps F103 and F104, and the system controller 11 monitors the operation of the exchange key and the change of the display mode. That is, every time the exchange key is operated, the magnitude relationship between the track name and the disc name on the display is exchanged. If the user operates the display mode key, or if it is time for the system controller 11 to automatically switch the display mode based on the operation program, step F104
Then, the process proceeds to F107, and a display process corresponding to the changed display mode is executed.

For example, when the user operates the exchange key to change the character display of the track name and the disc name and displays the track name and the disc name, the user can change the track name and the disc name according to the user's preference. One of the character information items is displayed in a large size, and the visibility of the character information that the user wants to know can be improved.

FIGS. 2 and 3 show an example of the transition of the display mode and the change of the display state during the reproduction. Of course, other display modes may be adopted during the reproduction. Further, the display mode may be automatically switched in various other ways by the system controller 11 according to the operation state or the like.

4. Second Display Device Example FIG. 7 shows an example in which a segment type display is adopted as the display unit 20 of the playback device as shown in FIG. 1, for example. FIG. 7 shows a configuration example of a display segment. For example, in order to realize a disc number display 31, a track number display 32, and a time information display 33,
A segment 4 for a small-size character is formed, in which a segment for displaying a number is formed, and a plurality of segments capable of displaying alphabetic characters for realizing character information such as a disc name and a track name.
