In this specification, the above-mentioned CD text information and necessary text information input by a user with respect to a disc which does not conform to the CD text standard are collectively referred to as “associated information”.

[First Embodiment of Shuffle Reproduction Processing] Next, a first embodiment of the shuffle reproduction processing according to the present invention will be described with reference to FIGS.

In response to the loading of the disc in the changer type reproducing apparatus as shown in FIG. 1, a storage processing routine 210 for accompanying information as shown in FIG. 3 is started. In this embodiment, a shuffle reproduction process, which will be described later, is performed using the accompanying information captured by the routine 210 and stored in the nonvolatile memory 42.

As shown in FIG. 3, in the process of storing the accompanying information described above, first, in step 211, each disk is compared with the disk currently loaded in the playback device and the disk stored in the magazine. It is determined whether the CD text standard is supported.

When each disc complies with the CD text standard, CD text information is fetched from each disc and stored in the CD text recording area of the nonvolatile memory 42 (see FIG. 1) as shown in FIG. It is recorded (steps 212 and 213).

When each disc does not comply with the CD text standard, a disc number which does not conform to the CD text standard is displayed, and the user is prompted to input necessary text information. When the user inputs necessary text information as shown in FIG. 4, the text information is registered in the user input information registration area of the nonvolatile memory 42 (steps 214 to 216).

The processes of steps 211 to 216 as described above are sequentially executed for each disk until it is determined in step 217 that all disks have been checked, and the process is completed after all disks have been checked. I do.

The user input information may be made to be selected by the user by, for example, displaying a genre example or displaying the performers in descending order of the number.

As described above, when a large-capacity hard disk is connected, the CD text data corresponding to the music data of all the songs recorded on the hard disk is also stored as the accompanying information as described above. The same processing is performed.

In this embodiment, the auxiliary information of the disk once read, that is, the CD text data and the user input data are stored in the corresponding area 4 of the nonvolatile memory 42.
2t, 42u, when the same disk is loaded in the apparatus again, the auxiliary information can be called up by reading only a part of the TOC information of the disk, and the shuffle reproduction processing described later is executed. In doing so, the time until the start is reduced.

Next, the processing routine 200 of the shuffle reproduction processing will be described with reference to the flowchart of FIG.

In the first step 201, a desired shuffle mode is selected from the following modes 1 to 3 based on a predetermined key input by the user.

In this embodiment, mode 1 is a disk shuffle mode in which the selection is limited based on text information, and mode 2 and mode 3 are
They are respectively set to the in-disk shuffle mode and the all-disk shuffle mode as in the prior art.

In step 202, it is determined whether the shuffle mode selected by the user is mode 1, mode 2 or mode 3. Here, when the mode 2 or the mode 3 is selected, the process proceeds to step 203 or step 204, respectively, and the reproduction in the in-disk shuffle mode or the reproduction in the all-disk shuffle mode is executed in the same manner as in the related art.

If, in step 202, mode 1, that is, the mode of disc shuffle reproduction limited to the selection target is selected, the process proceeds to step 221 to use text information for specifying the target of limited shuffle reproduction. Key input of selection by the user. In this example, the targets of limited shuffle reproduction are “target 1; specify genre” and “target 2; specify player”. One of the targets is selected by the user, and Text information of a specific genre name or performer name is specified and input.

In the case of this example, when the user selects the target 1 or the target 2, a list of genre names or performer names that can be selected for the target is displayed on the screen of the display 38. It is displayed and can be performed by the user selecting and specifying a desired genre name or player name from the screen.

It is needless to say that the user can also directly input the desired genre name or performer name to specify text information for specifying the target of limited shuffle reproduction.

In the next step 222, it is determined whether the target selected by the user is target 1 or target 2, and if target 1 is selected, that is, it is determined that a specific genre is selected. If so, step 22
Then, the process proceeds to step 3 in which the search is performed using the text information on the genre name designated and input by the user as the search element for the accompanying information of all disks stored in the non-volatile memory 42 as described above. A disc of the same genre as the input genre is selected.

On the other hand, if it is determined in step 222 that the target 2 has been selected, that is, if it is determined that a specific player has been selected, the process proceeds to step 224 and, as described above,
A search is performed for the accompanying information of all the disks stored in the non-volatile memory, using the text information about the player name specified and input by the user as a search element, and the same player as the specified and input player is searched. Is selected.

Then, step 223 and step 224
In either case, the process proceeds to step 225, where the order of shuffling in mode 1 is determined for a specific genre or a plurality of discs of a specific player selected by the search, and the sequence information of this order determination is It is stored in the RAM 33 (see FIG. 1) of the microcomputer. After a while
The shuffle reproduction processing routine 200 ends.

In the shuffle reproduction at this time, the reproduction order of a plurality of disks is determined according to a random number. However, all songs recorded on the plurality of discs may be shuffle-reproduced in accordance with random numbers.

After the above-described routine 200 is completed, the key operation for starting the shuffle performance is awaited, although not shown, and if there is a key operation for starting the shuffle performance, the information stored in the RAM 33 of the microcomputer is stored. Perform shuffle performance in this order.

As described above, according to the present embodiment, based on the accompanying information stored in the non-volatile memory 42, that is, the CD text information and the required text information input by the user, the magazine is stored in the magazine of the changer. It is possible to select only a specific player or a specific genre of the discs among the plurality of discs, and perform the shuffle reproduction.

In this embodiment, for a disc that does not comply with the CD text standard, the required text information input by the user is registered in the non-volatile memory 42, so that the disc that does not conform to the CD text standard is registered. As described above, the disc shuffle can be performed by selecting only a disc of a specific player or a specific genre, as described above.

In the above-described embodiment, in the shuffle reproduction in mode 1, only the disc of a specific player or a specific genre is selected and the disc is shuffled, but all the loaded discs are shuffled. It is also possible to select all musicians of a specific genre or a specific genre recorded on the disc and to shuffle only the selected music.

The selection is not limited to the performer or the genre. For example, a lyricist or a composer may be selected.

[Second Embodiment of Shuffle Reproduction Processing] Next, a second embodiment of the shuffle reproduction processing according to the present invention will be described. In the second embodiment, a disc and a plurality of music pieces selected as a search element using the same genre or the same player are not continuously played, and a varied shuffle playback is performed. is there. FIG. 5 shows an example of the shuffle reproduction processing routine 300 according to this embodiment.

As shown in FIG. 5, the first step 301
Then, a desired shuffle mode is selected from the following modes 1 to 3 based on a predetermined key input by the user.

That is, in the second embodiment, mode 1 is a disk shuffle mode in which continuous reproduction of a selection target is prohibited, and mode 2 and mode 3 are the same as in the conventional disk shuffle. Mode and all disk shuffle mode.

In the next step 302, it is determined whether the shuffle mode selected by the user is mode 1, mode 2 or mode 3. If mode 2 or mode 3 is selected, the process proceeds to step 303 or step 304, respectively, and the reproduction in the in-disk shuffle mode or the reproduction in the all-disk shuffle mode is executed in the same manner as in the related art.

If the mode 1 is selected in step 302, that is, if the disk shuffle mode in which the selection is not continued is selected, the process proceeds to step 321 and the text information as the accompanying information stored in the nonvolatile memory 42 Then, the process proceeds to a process of specifying a shuffle target.

As described above, when a large-capacity hard disk is connected, the CD text data corresponding to the music data of all the songs recorded on this hard disk is also stored as the accompanying information as described above. The same processing is performed.

In step 321, a key input for selection by the user of a text for specifying a shuffle target is accepted. In this example, the designated shuffle targets in this mode are “target 1; specify genre” and “target 2; specify player”, and one of the targets is selected by the user. Then, for the target, text information of a specific genre name or a performer name is specified and input.

Also in this example, when the user selects the target 1 or 2 by inputting text information, a list of genre names or performer names that can be selected for the target is displayed on the screen of the display 38. Can be performed by the user selecting and specifying a desired genre name or player name from the screen.

The user can also directly input a desired genre name or performer name to specify text information for specifying a limited shuffle reproduction target.

In the next step 322, it is determined whether the target selected by the user is 1 or 2, and if target 1 is selected, that is, if it is determined that a specific genre is selected. Proceeds to step 323 to search for the accompanying information of all the disks stored in the non-volatile memory 42 as described above, using the text information on the genre designated and input by the user as a search element. , A disc of the same genre as the genre designated and input is selected.

On the other hand, if it is determined in step 322 that the target 2 has been selected, that is, if it is determined that a specific player has been selected, the process proceeds to step 324 and, as described above,
A search is performed for the accompanying information of all the disks stored in the non-volatile memory, using the text information about the player name specified and input by the user as a search element, and the same player as the specified and input player is searched. Is selected.

Then, steps 323 and 324 are executed.
In either case, the process proceeds to step 325 to determine whether or not the genres or the performers of all the discs loaded in the reproducing apparatus are the same.

If it is determined in step 325 that the disc loaded in the playback device includes a disc of a different genre or a different player, the process proceeds to step 326, where the discrimination selected by the search is performed. So that discs of a particular genre or a particular player are not continuous
The order of shuffling in mode 1 is determined, and the array information for this order determination is stored in the RAM 33 of the microcomputer. Thereafter, the shuffle reproduction processing routine 30
0 ends.

In this case, in order to prevent discs of a particular genre or a particular player selected by the search from continuing, discs that are not selected are inserted between the selected discs. , The disk arrangement is determined. Then, in this example, the order of the plurality of selected disks and the order of the plurality of unselected disks inserted therebetween are determined according to random numbers.

On the other hand, when all discs loaded in the apparatus have the same genre or the same player, the process proceeds to step 327 to execute the mode 1 in which continuous play is prohibited and shuffling is performed. After the display 38 indicates that it cannot be performed, the shuffle reproduction processing routine 300 ends.

After the above-described routine 300 is completed, although not shown, the key operation for starting the shuffle performance is awaited. If there is a key operation for starting the shuffle performance, the information stored in the RAM 33 of the microcomputer is stored. Perform shuffle performance in this order.

By the way, for example, if there are many discs of the same player, the disc of the same player may continue from the middle of the mode 1 shuffle. In this case, the fact that the shuffle mode is switched in the middle may be displayed to alert the user.

As described above, in the second embodiment, the accompanying information stored in the nonvolatile memory 42, that is,
Based on the CD text information and the required text information entered by the user, a disc of a specific player or a specific genre is selected from among a plurality of discs stored in the magazine of the changer, and a disc of the selected disc is selected. As we banned continuation and performed disk shuffle,
A variety of shuffle reproduction can be realized.

In the second embodiment, for a disc that does not support the CD text standard, the required text information input by the user is registered in the non-volatile memory 42 so that the disc does not conform to the CD text standard. Even when compatible discs are mixed in the magazine, as described above, only discs of a specific player or a specific genre should be selected, and disc continuation of the selected discs should be prohibited, and disc shuffling should be performed. Can be.

In the above-described second embodiment, in the shuffle reproduction in mode 1, a disc of a specific player or a specific genre is selected, and a disc shuffle in which continuation of the selected discs is prohibited is performed. However, it is also possible to select all the musicians of a specific genre or a specific genre recorded on all the loaded disks, and to perform a shuffle in which the continuation of the selected music is prohibited.

The selection is not limited to the performer or genre. For example, a lyricist or a composer can be selected.

[Third Embodiment of Shuffle Playback Processing] In the description of the first and second embodiments described above, when a disc is not compatible with CD text when a disc is loaded, text such as a disc title, a player, a genre, etc. Although the registration of the information by the user is accepted, the input of the text information by the user with respect to the disc which does not support the CD text is accepted at the time of the shuffle in the mode 1 in which the search is performed using the text information. You can also The third embodiment is an embodiment in that case.

FIG. 6 shows a main part of a processing routine of a shuffle reproduction process for explaining an example of the third embodiment in consideration of the above points in the case of the first embodiment. Step 222 of the processing routine 300 of FIG. 2 described above.

That is, in the case of the third embodiment,
In step 223 or step 224, when the text information on the genre name or the player name is searched, respectively, step 231 or step 2 is performed.
Proceeding to 34, it is determined whether or not any of the loaded disks has no text information in the nonvolatile memory 42. This is a determination of whether the disc is a disc that does not support CD text, or a disc that does not support CD text and does not accept input of text information by the user.

Step 231 or step 234
When it is determined that there is a disk having no text information in the non-volatile memory 42, the process proceeds to step 232 or step 234, respectively, where the disk number for which the text information is not stored in the memory 42 is displayed. Then, the user is prompted to input required text information. When the user inputs necessary text information as shown in FIG. 4, in step 233 or step 236, the input text information is stored in the user input information registration area 42u of the non-volatile memory 42. (Information on the total number of programs and the total playing time).

If it is determined in step 231 or step 234 that the text information has been stored in the nonvolatile memory 42 for all the loaded disks, the process proceeds to step 225 from both step 231 and step 234. Then, the shuffle order of mode 1 is determined for a specific genre or a plurality of discs of a specific player selected by the search, and the arrangement information of this order determination is stored in the RAM 33 of the microcomputer. You. Thereafter, the shuffle reproduction processing routine 200 ends.

[Further Embodiment] In each of the above embodiments, the case where the present invention is applied to a changer-type CD reproducing apparatus has been described. However, the present invention relates to a changer-type reproducing of a mini disk (MD). The same applies to the device.
