Then, the CPU 24 refers to the data held in the disk information table, creates display image data on the V / RAM 21, and causes the V.RAM 21 to execute the display as shown in FIG. 5B, for example. become.

For example, as shown in FIG. 5B, the display screen 8a
A display is made on the top of which the disk set on the tray TR is imitated by a circular icon of a predetermined size. Then, at a position corresponding to the storage position S ₁ of FIG. 5A, a disc icon "SUPER" is displayed on a circular icon.
"MAN" (in this case, movie software) and "Vol. 2" indicating the volume number are displayed.
In addition, a circular icon smaller than usual is displayed at a position corresponding to the storage position S ₂ corresponding to the size of the electronic book actually set, and "Kojien" indicating the disc title is displayed in the icon. Is displayed in. Also, the position of the icon corresponding to the position of the KARAOKE-CD storage location S ₃ based on the data of the disk title, for example, a title character such as "Japanese Enka 1" is displayed. Also, the CD-D at the storage position S ₄
In the icon corresponding to the position A, it is usually CD-D
Since the disc title data is not recorded in A, a display such as "AUDIO" is made to indicate that it is a CD-DA. The icon at this position is shown by a broken line. This broken line may have any display form in practice, however, for example, a blinking display or a change in brightness indicates that the "disk selection display" indicating the disk currently being selected by the user is displayed. There is.

Further, in the icon corresponding to the position of the video CD in the storage position S ₅ , "SUPER MAN" indicating the disc title and "Vol. 1" indicating the volume number thereof are displayed. In this case, since the same album as the video CD set in the storage position S ₁ is continuously wound, the volume number order is indicated in such a case, for example, arrow V in the figure. Is displayed. Note that the display of the wedge-shaped pointer shown by P in this figure is the display showing the position of the reproducing head H described in FIG. 5A, and the display at the lower right of the screen is actually provided on the remote controller 30. Left and right keys 49,5
This is a display showing the user the direction in which the disc selection display, which will be described later, moves in response to an operation of 0. Although not shown in the figure, with respect to discs that can be distinguished in logical format, a specific color is made to correspond to each format, and each icon is displayed by this color. For example, FIG. 5 (b)
, The video CDs corresponding to the storage positions S ₁ and S ₅ are indicated by the icons of the same specific color, and the electronic books (“Kojien”) or KARA set in the other storage positions.
OK-CD (“Japanese Enka 1”) and CD-DA are displayed as icons for different specific colors.

Then, when the electronic book "Kojien" is selected and reproduced from the state where the disc is set in this way, the following process is performed. In the state shown in FIG. 5B, if the user has not performed a selection operation, the icon of the CD-DA on the pointer P corresponding to the reproducing head becomes different from that of another disc due to, for example, blinking or high brightness. It is displayed so that it can be distinguished (shown by a broken line). As described above, this display is a "disk selection display" indicating that the disk has been selected by the user's selection operation. For example, when the user's selection operation has not been performed yet, the display is on the pointer P. Since this display is performed using the disk as the default position, the above-mentioned display is obtained.

Next, the user can select the disc to be reproduced next, for example, by moving the disc selection display one by one in any direction by operating the left and right keys 49 and 50 of the remote controller 30, for example. . For example,
If it is desired to select an electronic book (“Kojien”), the right key 50 is operated twice to sequentially move the disk selection display, and the icon of the electronic book (Kojien) is selected and displayed. Then, the user next operates the enter key 45. Then, the tray TR of the disk storage portion 9a is actually rotationally driven inside the device main body,
As shown in FIG. 5C, the electronic book (shown by EB) set in the storage position S _{2 is} brought to the position of the reproducing head. Along with this, on the display screen 8a as well, the icon display imitating the tray TR is displayed such that it rotates counterclockwise, for example, as shown in FIG.
As shown in, the icon of the electronic book (“Kojien”) is brought to the position of the pointer P. After that, for example, in response to the operation of the disc playback key 42, or immediately as it is, the playback corresponding to the logical format of the electronic book (“Kojien”) is performed, and the switches 6 and 15 are also responded at this time. By switching, for example, the display screen 8a is switched from the disc menu display to a state in which the reproduction content of the electronic book is displayed, and an electronic book (for example, EB-XA) in which audio data is recorded as the type. If so, the sound is also output from the speaker 18. Even when another disc is selected and reproduced by the same operation as described above, reproduction corresponding to the logical format of the disc is performed, and image display and audio output are performed.

By the way, if the disc menu key 43 is operated again to call up the disc menu display from the state in which the electronic book ("Kojien") is selected and reproduced as described above, at this time, the reproduction of the electronic book is performed. The operation is continued. In such cases,
As shown by the icon at the position of the electronic book (“Kojien”) in FIG. 5D, for example, an image in which the outer peripheral portion R moves in the direction indicated by the arrow is displayed, and the disc currently being reproduced is displayed. Is made available to the user. Note that the display form indicating this reproduction is merely an example, and it may be displayed in other display forms.

Further, in this embodiment, a program function for registering the reproduction order of a plurality of discs as a program and performing continuous reproduction is provided. As a result, for example, as shown in FIG.
When the disc is set as shown in, the movie software of the video CD, "SUPERMAN" -V
By registering ol.1 and "SUPERMAN" -Vol.2 as a program, these two discs can be continuously played in the order of volume numbers without performing the above-mentioned operation for selective playback. .

The operation for registering such a program is also used by the remote controller 3 used in the previous operation for selective reproduction.
This can be done by operating the program key 44 in addition to the 0 left / right keys 49, 50 and the enter key 45.

For example, when the disc menu is displayed as shown in FIG. 5B, "SUPERRM" is displayed.
AN ”-Vol. 1 and“ SUPERMAN ”-Vol.
In the case of program playback of 2 sequentially, first, the disk selection display is operated by operating the left / right keys 49, 50.
After setting it to the position of the icon of RMAN ”-Vol.1, the program key 44 is operated. After this operation, the icon "SUPERMAN" -Vol. 1 is displayed in a form indicating that the program has been registered (for example, brightness change, color change, blinking at a predetermined timing).
By doing this, the user can confirm that the disc to be programmed is set first.

At this time, in the CPU 24, the RAM 27
Based on the disk information table stored in the disk, it is possible to determine the presence / absence of the disk with the next volume number registered in the program and the storage position in which the disk is set. Therefore,
In this case, "SU to be reproduced next in the storage position S ₁ "
Since there is a PERMAN ”-Vol. 2 disc, the icon at the position corresponding to this disc is displayed and changed in a predetermined display form. As a result, unlike the case shown in FIG. 5B, when the discs of the same album are set in separate storage positions without being lined up, or a disc in which one album is made by a larger number of discs When the disk is properly set at each storage position, it is useful because the disk to be registered next can be known at a glance. The user may ignore this display and program-register another desired disk.

Then, the user, for example, uses the left / right key 4
With operation of 9, 50, with the disk selection display on the position of the icon of "SUPERMAN" -Vol.2.
The program key 44 is operated. As a result, the display indicating that the program has been registered is displayed as "SUPERM
AN ”-From the Vol. 1 position icon, select“ SUPER
MAN ”-Switches to the icon at the position of Vol.2. In the operation steps so far, if it is desired to cancel the program-registered disc and start again, the operation of the cancel key 46 causes, for example, all the data of the disc registered so far to be canceled, or the disc registered immediately before. It is possible to cancel the created disc.

Then, for example, when the user thereafter operates the enter key 45, the display portion simulating the tray TR is rotated as described above, and "SUPERMA" is displayed.
N ”-Vol. 1 icon is displayed so as to come to the position of the pointer P, and inside the device body, the tray TR is set so that the disc actually set at the storage position S ₅ comes to the position of the reproducing head H. Is rotated. Then, in response to the subsequent operation of the disk reproduction key 42 or the operation of the enter key 45, the functional circuit section including the disk changer section 9 and the switch sections 6 and 15 immediately outputs a video CD. It is controlled so as to correspond to the operation, and thereafter, automatic reproduction is performed according to the designated program order.

In the above description of the operating method, the program operation is performed so that the video CDs of the same album (continuous volume) are continuously reproduced. CD-DA and KAR
Continuous reproduction between discs having different logical formats, such as program reproduction of AOKE-CD, is possible by the same operation method. However, for example, since an electronic book does not make sense due to its usage method, such a continuous reproduction does not make sense, so it seems that the user performed a program registration operation for a disc that is not compatible with continuous reproduction like an electronic book. In this case, for example, this operation is invalidated, and a program operation of another type of disc corresponding to continuous playback is prompted, or the program registration so far is canceled and the operation for selective playback described above is performed. Therefore, it is preferable to perform processing such as switching the display so as to perform the disc selection display for the disc icon.

Further, in this embodiment, as shown in FIG.
Since it is possible to output the voice generated by the synthetic sound generation unit 23 from the speaker 18, it is possible to hold the voice data corresponding to the ROM 28 in advance and to make sure that the various key operations described above are performed. It is also possible to output the voice as shown.

Next, referring to FIGS. 6 (a) and 6 (b), a specific example of the disc menu display when discs are connected in a state different from that of FIG. 5 will be described. In these figures, the same parts as those in FIG. In FIG. 6A, a video CD is set in the storage position S ₁ and the video CD is
Video software has been designated as R and is not intended for children. Further, the storage position S ₂ is in an unloaded state in which no disc is set. Then, the storage position S ₃ CD-DA is in the storage position S ₄ is PHOTO-CD is in the storage position S ₅ is loaded CD-G, respectively. Then, the storage position S ₄ corresponds to the position of the reproducing head H.

With the disc thus loaded, the disc menu display is shown, for example, as shown in FIG. 6 (b). In this figure, at the position corresponding to the current storage position S ₁ on the display screen 8a, the disc title of the video CD (for example, "Mrs Chatterley's lover") is shown against the circular icon corresponding to the disc size. In addition, a display indicating that this disc is R-designated is made.

Here, the background of a so-called rating system relating to video software including R designation will be described. For example, American film associations consider the effects of sexual, violent or cruel depictions on youth, and depending on the content of each work, G (no age limit), PG (need parental guidance) ), PG-13 (requires parental supervision, and depending on the work, people under 13 should not enter), R designation (under 18 years old must be accompanied by parents or adults), X designation (so-called adult) Movies: 18
Children under the age of admission are not admitted) are classified into each rank. Even in the case of publishing video software and game software in the home country, following the rating system as described above, starting with general designation without age limitation, rating (classification) by R designation, X designation (adult designation) However, there are some movements due to self-regulation such as clearly indicating this to software packages and the like.

Therefore, when such data indicating general designation, R designation and X designation is inserted into the TOC information or directory information area of the disc, this data is also stored in the RAM 27. It is possible to store the data in the disk information table, and if the image display showing the rank of the disk rating can be created in the V / RAM 21 based on this data, the structure shown in FIG. Like the display of “R designation” of the icon corresponding to the storage position S _{1 of} , the display indicating the rating rank can be performed. Although not shown in the figure, in the case of a disc that is not intended for children with a rank of R or above, a color that can give an image of a warning, such as red, is used, for example, the icon 6 is displayed, or in the case of FIG. 6B, the character display of "R designation" may be displayed in this color. For example, without such a rating rank display, it may be difficult to judge which disc is subject to age restriction from the disc menu display simply by disc title. Therefore, if such a rating is displayed, it is possible to immediately know which disc is subject to age restriction, and if it is used by a family, for example, software that does not want to be shown to children. You will be able to consciously avoid and select. It should be noted that it is conceivable that such a disc that has been designated with such an age may not be reproducible unless a password is entered so that a child or the like cannot replay it without permission.

Further, the display of the icon corresponding to the current storage position S ₂ is conceptually that the disc is not loaded because the disc is not actually set as shown in FIG. 6A. In order to make it visible, for example, a change in brightness or a change in color is displayed, or "N
It may be indicated by a character display such as "O DISC". Further, the icon display corresponding to the storage position S ₃ is the same display as that described above for the icon display corresponding to the storage position S ₄ in FIG. 5 since the disc set here is a CD-DA. Is done.

At the next storage position S ₄ , PHOTO-
CD is set. Usually, this PHOTO-CD
No data indicating the disc title is recorded on the disc. Therefore, for example, as shown in FIG. 6B, the character "PHOTO" is imposed in the icon at the corresponding position, and further, for example, the first photo image of PHOTO-CD is reduced and displayed. By doing so, the user can know at a glance what content the PHOTO-CD is set to. In order to realize this display form, for example, the data of the first photo image reproduced by the disc changer unit 9 of FIG. 1 is supplied from the video decoding processing unit 11 to the image memory 31 to be written and stored therein. (At this time, in the video decoding processing section 11, the signal output to the D / A converter 12 is stopped by switching the internal switch). Then, by superimposing the data of the image memory 31 read at a predetermined timing as a video signal on the video signal of the disc menu display supplied from the display controller 22 to the video synthesis processing unit 7, FIG. It is possible to display as shown in b).

A CD-G is loaded in the storage position S ₅ . Since the CD-G is the same as the CD-DA in the logical format as described above, the CPU 2
It is difficult to determine whether to discriminate between the CD-DA and the CD-G according to No. 4. Therefore, the PHOTO-
Similar to the icon display in the case of the CD, the data of the still image reproduced by the disc changer unit 9 is reduced and displayed in the icon at the corresponding position. Then, as in the case of the CD-DA, as shown in the icon display of the position corresponding to the storage position S ₅ in FIG.
The character “IO” is displayed, and the still image recorded on the CD-G is combined and displayed, and the user does not see CD-DA or PHOTO-CD.
It can be easily recognized that it is G. And
Also in the case of FIG. 6, it is possible to reproduce a desired disc by the operation method of selective reproduction and program reproduction described above with reference to FIG.

As described above, in the present embodiment, the size of the disk stored in the disk storage section 9a and the data recorded in the management area of the disk are used to generate the data shown in FIGS.
And the disc menu display as shown in FIG. 6B is created. For this purpose, the size of the disc detected as described above and the required data extracted from the TOC information and directory information of the disc are created. Whenever a disc is newly replaced or loaded, the RAM 27
Is held as a disc information table.

Then, with reference to the flow chart of FIG. 7, the loading operation of the disk housing portion 9a and the discriminating operation of the disk type and the processing operation of the CPU 24 at the time of writing to the disk information table will be described.
For example, when the information that the eject key 40 is operated as shown in step F101 is obtained from the state where the disk storage substrate B of the disk storage portion 9a is stored in the device main body 0, the CPU 24 proceeds to step F102 and The loading mechanism is controlled so as to unload the storage substrate B, and the process proceeds to step F103, where the operation of the eject key 40 is again in a standby state. During this period, the disc storage board B is kept in the pulled-out state as shown in FIGS. 2 and 3, and the user operates the tray rotation key K to load a disc at an arbitrary storage position. Will be there.

Then, in step F103, the eject key 4 is pressed.
When it is determined that the operation of 0 has been performed, the process proceeds to step F104, and the disc storage substrate B is loaded (pulled in).
Is performed, and the process proceeds to step F105. In step F105, it is determined whether or not a loading error has been detected.For example, if the disc is not correctly mounted in the mounting position, a disc other than the prescribed size is mounted, or a foreign object is caught, When the loading error is detected, the CPU 24 causes the step F102.
Will return to. On the other hand, if the loading error is not detected in this step, the process proceeds to step F106 to set the variable n = 0. This variable n corresponds to the number of movements of the tray TR for each storage position.

In the next step F107, it is determined whether or not the disc is set at the storage position (any of S _{1 to} S ₅ ) corresponding to the position of the reproducing head at present. This is determined by the detection output of the size detection unit 10a, for example. Alternatively, it is possible to determine whether the TOC data can be read by the reproducing head. And
If it is determined in this step that the disc is not set, a process of resetting the data of the disc information table corresponding to the storage position corresponding to the reproducing head H is performed (F116), and the process proceeds to step F115. On the other hand, when it is determined that the disc is set, the size of the disc is detected by the sensor (F108), and the TOC information is further detected from the disc by the disc driving device (reproducing head H).
The directory information is read to obtain information about the logical format, the disc title, the volume information, the age-specified rating, etc. necessary for displaying the disc menu (F109), and the process proceeds to step F110.

In this step F110, the previous step F109
It is determined from the TOC information and the directory information read in step S1 that the logical format of the disc is compatible, and if it is determined that it is not compatible, the process returns to step F102, for example, and unloading is performed. Prompt you to remove this unsupported format disk. Although not shown in this routine,
At this time, it is preferable in terms of usability for the user that some kind of display indicating that a disc having an unsupported format is loaded is displayed on the display screen 8a. On the other hand, if it is determined that the format is not unsupported, the process proceeds to step F111, the data of the disk information table corresponding to this storage position is read and referred to, and it is compared whether it is the same as the data obtained in step F109. . If it is determined in this step that the data is not the same as the data in the disk information table already held, it means that a new disk has been set in this storage position, so the CPU 24 proceeds to step F112. Then, the data of the disc information table corresponding to this storage position is rewritten to the data newly obtained in step F109. on the other hand,
If the compared data are the same, this means that the disc has not been replaced.In this case, the process of step F112 is skipped, and the process proceeds to step F113 without rewriting the data. move on. Step F113
Then, the tray TR is rotated in the predetermined direction by one storage position. As a result, the storage position on the next tray TR comes to the position of the reproducing head H. For example, if the storage position S ₄ is at the position of the reproducing head before the movement of the tray TR, and the tray TR is configured to rotate clockwise, then the storage position S ₅ is changed to the reproducing head. You will be in position H.

In the next step F114, it is determined whether or not the variable n = 4. Where the variable n =
If it is determined that it is not 4, the routine proceeds to step F115, where the variable n is incremented to n = n + 1 and then the routine returns to step F107. Thus, in step F114, the variable n = 4
The process from step F107 to step F113 is repeated until it is determined that, while moving the storage position one by one to the position of the reproducing head H, each time,
This is an operation for obtaining the disc information table of the disc at the storage position. Then, in step F114, the variable n
= 4, all the disc information tables corresponding to the five storage positions have been rewritten to the ones corresponding to the currently set discs, and the tray TR has just 1 This corresponds to the state of the storage position when rotated and loaded. In this way, the CPU 24 finishes rewriting the disc information table after loading, and thereafter, it becomes possible to create and display the disc menu display based on this data.

Then, the processing operation of the CPU 24 accompanying the reproduction by the selective reproduction operation and the program designating operation while displaying the disc menu and this screen will be described with reference to the flowchart of FIG. When it is detected that the disc menu key for displaying the disc menu is operated by the user's operation of the remote controller 30 (F201), the CPU 24 refers to the disc information table of the RAM 27 and controls the V / RAM 21. To create an image of the disc menu display (F202).
As a result, the display screen 8a is displayed on the screen shown in FIGS.
The disk menu display as shown in (b) is displayed, and then the CPU 24 proceeds to step F203 to determine whether the left and right keys 49 and 50 for moving the "disk selection display" have been operated. Will be determined.

If it is determined in step F203 that the left / right keys 49, 50 have been operated, the process proceeds to step F204, and display control is performed so that the "disc selection display" is moved to the icon in the direction corresponding to the operation. Go to Step F2
Go to 05. On the other hand, if it is determined that the left / right keys 49 and 50 are not operated, the process directly proceeds to step F205 and it is determined whether or not the program key 44 is operated. If it is determined that the program key 44 has been operated, it is determined that the disk at the storage position corresponding to the icon currently selected and displayed is registered as a program, for example, in the area of the program registration data of the RAM 27. , Set the data indicating the specified storage position according to the program number order (F206), and then step F2.
However, if it is determined that the program key 44 has not been operated, the process directly proceeds to step F207.

At this step F207, the enter key 45
If it is determined that the enter key 45 has not been operated, the process returns to step F203, and the processing up to step F207 is repeated, during which the user performs the selective reproduction operation or the program. The specified operation can be continued.

On the other hand, if it is determined that the enter key 45 has been operated, the CPU 24 proceeds to step F209 to determine whether or not there is program registration data at the present time, and here, the data registered in the program at the previous step F207 is determined. If it is determined that the disc is not present, the process proceeds to step F210 as a normal selective reproduction operation, and the tray TR is rotated so that the disc (storage position) at the position where the disc selection display is currently performed is at the reproduction head position. At the same time as moving the disc, the flow advances to step F211 to display a disc simulating the rotation of the tray so that the icon selected and displayed on the disc comes to the position of the instruction display P corresponding to the reproducing head.
-Control the RAM 21. Then, the disc selected in the next step F212 is reproduced according to the logical format and recording form.

If it is determined in step F209 that the program registration data exists, the enter key 45
This means that the disc program registration operation was performed at a stage prior to the operation. Therefore, thereafter, the processing for reproducing the discs according to the program order will be executed. In this case, the CPU 24 first proceeds to step F213, and the total number of the discs designated by the program (that is, the registered discs are registered). The variable TR (corresponding to the program number) is set to m = 1, and the process proceeds to step F214, in which the tray TR is moved so that the storage position of the disc corresponding to the program number m of the program registration data is at the position of the reproducing head. Rotate, then step F2
Proceeding to step 15, control is performed so that the rotation display is executed so that the disc icon corresponding to the program number m comes to the position of the instruction display P. And step F2
Proceeding to step 16, the control for executing the reproduction of the disc on the storage position at the position of the reproducing head is performed, and when the reproduction of this disc is completed, the routine proceeds to step F217, where the variable m =
It is determined whether it is FULL, that is, whether all the discs registered in the program have been reproduced. If it is determined that the variable m = FULL is not established, the CPU 24 proceeds to step F218, increments the variable m = m + 1, and returns to step F214. By repeating the processing of steps F214 to F218, the disc is reproduced in the order designated by the program. If it is determined that the variable m = FULL, the disc reproducing operation is terminated and the routine is exited.

In the above description, the disc storage portion 9a of the disc changer portion 9 is of a type in which the disc at the storage position on the tray TR is placed flat, but the present invention is not limited to this type. A so-called cartridge type in which the disks DY are housed in a state of being stacked in the cartridge C as shown in FIG. 9 can be considered. Then, when the disc menu display in the case of such a cartridge type disc storage portion 9a is displayed in a form as shown in FIG. 10, for example, it becomes similar to an image in which a disc is actually loaded,
The usability for the user is also improved. For example, in this figure, icons that imitate the disk shape and its size are displayed in the approximate center position of the display screen 8a in correspondence with the positional relationship of the actually loaded disks, and icons corresponding to the respective icons are displayed on the left side thereof. Characters indicating the disc type and disc title are displayed. In this case, the up / down keys 47 and 48 provided on the remote controller 30 move the instruction display P corresponding to the position of the reproducing head up and down with respect to the position of each disk.

Further, the circuit configuration and appearance of the AV equipment, the specific display form of the disc menu display, the operation procedure such as selective reproduction and program designation, and the actual processing operation of the CPU 24 according to the above are now described. It is not limited to what has been described above, and various modifications are possible. For example, in the present embodiment, the circuit configuration of the AV equipment has been described as a composite-type equipment in which a television, a disc changer, and a karaoke function are integrated. However, for example, at least one of the above-mentioned functional parts is provided separately. The present invention can be similarly applied to a composite type AV system configured. Alternatively, the disk changer unit 9 of the present embodiment and the functional circuit unit required for displaying the disk menu may be configured as a single disk changer.

[0071]

As described above, the AV equipment provided with the disc changer of the present invention has the disc format type currently loaded in the disc changer, the disc title, the album volume information, the rank designated by the age, and the like. While displaying the position status of the disc currently loaded in the disc changer while incorporating the information of the disc, the user can see what kind of disc is currently stored in what storage position by looking at the display screen. It is possible to easily know whether or not there is, and since it is possible to reproduce while selecting a desired disc on this screen, there is an effect that the usability is greatly improved. In particular, the present invention is different in various formats,
In devices that are made to be able to play multiple types of discs, the usage as software will also be miscellaneous,
This is very effective because it can eliminate user confusion when selecting a disc to be played.
