DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium reproducing apparatus, and particularly to a CD player, a video CD player, a CD changer player, a video CD changer player,
D player, LD changer player, DAT, etc.
For recording media such as CDs, video CDs, LDs, and DAT tape cassettes, songs that are recording units in the recording media,
When playing a program by unit information such as track, index, entry, program, chapter, etc., or by using a CD changer player, video CD changer player, LD changer player, etc.
The present invention relates to a recording medium reproducing apparatus which allows a user to easily and easily perform a program registration operation when reproducing a program for each recording medium such as D and LD.

[0002]

2. Description of the Related Art For example, a CD player has
A program reproducing function for reproducing only a desired music in the program is provided. Specifically, after turning on the program mode key on the operation panel to set the program mode, enter the desired track number (track number) using the numeric keys, and the system controller stores the program number in the program file area of the internal memory. Register in order as a program song. After the registration is completed, when the PLAY key is turned on, the system controller controls the reproducing means to reproduce each program music in the order of registration in the program file area. When the program mode is released, the system controller clears the program file area and allows a new program to be registered.

[0003]

However, in the conventional program reproducing function, in order to program a desired music, it is necessary to confirm the music number in advance.
The song name of the desired song is not well understood because it has not yet been purchased and the song name of the desired song is mistaken when trying to find the song number by looking at the lyrics card or label, and the song is not the desired song Was entered incorrectly. In order to prevent a program error, the user must release the program mode to play the desired music, check the music number from the display, and then set the program mode and key input, which is troublesome. Also, play the desired song and play C
Even if D and the track number are checked, an incorrect track number may be input due to a mistake in operating the numeric keys. In particular, many C
In the case of a changer player in which D is stored and exchanged and played back, it is difficult to prevent a program mistake because a desired song is spread over a large number of CDs, resulting in a mix-up of CDs. If a program error occurs, the user must once release the program mode to clear the program file area, then set the program mode again and input a key again, which is troublesome.

In the changer player, it is conceivable that the program is executed not for each music but for each CD. In this case, when a CD has already been stored in the CD storage section, a desired CD is stored as described above. There is a strong possibility that a mistake may be made in the location of the CD in the CD compartment, and if a program error occurs, the program mode is canceled once, the program file area is cleared, and then the program mode is set again. You have to enter it, which takes time.

An object of the present invention is to provide a recording medium reproducing apparatus in which a user can easily and easily perform a program registration operation in view of the problems of the related art. It is another object of the present invention to provide a recording medium reproducing apparatus capable of easily performing a partial change after program registration.

SUMMARY OF] According to the present invention, song, track, index, entry, program, music unit by such a chapter, in the case of the recording medium reproducing apparatus for reproducing a recording medium in which information such as video is recorded, the registration instruction operation Means and the delete instruction operating means are shared by one register / delete instruction operating means, the unit information being reproduced is determined by the determining means, and the registration / delete instruction operation is performed during reproduction of the recording medium based on a reproducing operation other than program reproduction. Only when the means is operated, information specifying the unit information being reproduced at that time is stored in the program storage means as program information, and the registration / deletion instruction operation means is operated during reproduction of the recording medium based on the program reproduction operation. Only when operated, if program information consisting of information specifying the unit information being reproduced at that time exists in the program storage means, We want to delete. Thus, in the reproduction of certain unit information based on a reproduction operation other than the program reproduction, if the registration / deletion instruction operation means is operated while confirming that the unit information is the desired unit information, the unit reproduced at that point in time is operated. Since the information is registered as the unit information to be reproduced by the program, the program of the desired unit information can be surely executed by a simple operation. Further, in a state where the program information including the information for specifying the unit information to be program-reproduced is stored in the program storage unit, the unit information is to be deleted by the unit information to be deleted by the reproduction of a certain unit information based on the program reproducing operation. If the registration / deletion instruction operation means is operated while confirming that there is, the program information relating to the unit information is deleted, so that a partial change of the program contents can be surely executed by a simple operation. it can. Furthermore, since the registration operation and the deletion operation of the program information can be performed by one instruction operation means, the load on the configuration of the operation means can be reduced.

[0025]

According to another aspect of the present invention, in the case of a recording medium reproducing apparatus that reproduces information while exchanging a plurality of recording media on which information such as music and video is recorded, a registration instruction operation and a deletion instruction operation are performed by one operation. The registration / deletion instruction operation means is also used, and the recording medium being reproduced is determined by the determination means, and the registration / deletion instruction operation means is operated during reproduction of the recording medium based on a reproduction operation other than program reproduction. Only at that time, the information for specifying the recording medium being reproduced at that time is stored as program information in the program storage means, and only when the registration / deletion instruction operation means is operated during reproduction of the recording medium based on the program reproduction operation. If program information including information for specifying the recording medium being reproduced at that time exists in the program storage means, this is deleted. Thus, if the user operates the registration / deletion instruction operation means while confirming that the recording medium is the desired medium in the reproduction of a certain recording medium based on a reproduction operation other than the program reproduction, the reproduction is performed at that time. Since the recorded recording medium is registered as a medium for program reproduction, it is possible to reliably execute a program of a desired recording medium with a simple operation in a recording medium reproducing apparatus that reproduces while exchanging a plurality of recording media. . In addition, in a state where program information including information for specifying a recording medium on which a program is to be reproduced is stored in the program storage means, the medium is a medium to be deleted by reproducing a certain recording medium based on a program reproducing operation. If you operate the registration / deletion instruction operation means while checking
Since the program information related to the medium is deleted, it is possible to surely execute a partial change of the program contents by a simple operation. In addition, since the registration operation and the deletion operation of the program information can be performed by one instruction operation unit, the load on the configuration of the operation unit can be reduced.

The subcode is output to a system controller to be described later, and the audio data is output to a DA converter (not shown) and D / A converted, and then output to an external audio amplifier. C
The recording medium reproducing means is constituted by the D reproducing mechanism section 3 and the signal processing section 5, and the recording medium exchanging means is constituted by the changer section 4.

Reference numeral 6 denotes an operation unit, which includes a power key, a PLAY key, a STOP key, a program performance mode on / off key, a disk key for instructing a disk exchange, a numeric key for inputting a disk number to be exchanged, and a song feed. In addition to a key, a music return key, and the like, one registration / deletion key for instructing registration or deletion of a program music is provided. 7 is a system controller having a microcomputer configuration,
The overall control of the system is performed according to the operation on the operation unit 6. Specifically, power on / off, program reproduction mode on / off, CD exchange control, CD normal reproduction control, registration / deletion of program information in a program file area described later, program reproduction control, and the like are performed. . During the reproduction of the CD, the system controller 7
D and the music are determined. Specifically, a CD is identified by a disc number which is a storage location in the CD storage unit 2, and a music is determined by a music number (track number).

FIG. 2 is an explanatory view of data stored in the memory 8 built in the system controller 7. Reference numeral 8A denotes a current disk number storage for storing the disk number of the CD currently set in the CD reproduction mechanism 3. Area, 8B is C
TO read from the CD set in the D playback mechanism 3
This is a TOC storage area for storing C information. Reference numeral 8C denotes a program file area which stores, as information for specifying a combination of a CD to be program-reproduced for each of channels 1 to m and a song in the CD, program information in which a disc number and a song number are combined. The memory 8 is non-volatile such as by using a battery-backed SRAM or EEPROM, so that stored data is stored even when the power is off.

Next, the operation of the above embodiment will be briefly described with reference to FIGS. 3 and 4 are flowcharts showing the operation of the system controller 7, and FIG. 5 is an explanatory diagram of program information stored in the program file area 8C of the memory 8. It is assumed that n CDs 1 have been stored in the CD storage unit 2 in advance, and all the areas 8A to 8C of the memory 8 have been cleared. Further, it is assumed that the CD 1 is not set in the CD reproducing mechanism 3 and the program reproducing mode is off.

Reproduction other than Program Reproduction When the disk key is pressed in the program reproduction mode off and the exchange of the disk is instructed, and the disk number is designated by the numeric key, the system controller 7 sets the CD to
By controlling the changer section 6, if the CD playback mechanism section 3
When CD1 is set in the CD storage unit 2
After returning to the original position of
It is taken out of the D storage section 2 and set in the CD reproducing mechanism section 3. At this time, the disc No. of the CD1 currently set in the CD reproducing mechanism unit 3 is stored in the current disc No. storage area (see reference numeral 8A in FIG. 2) of the built-in memory 7A. It can be determined. Further, the CD playback mechanism 3 and the signal processing section 5 are controlled to control the TOC.
The information is read and stored in the TOC storage area (see reference numeral 8B in FIG. 2) of the built-in memory 7A so that it can be used for a search or the like (steps 50 and 51 in FIG. 3).

When the program playback mode is off and the CD
PLA when CD1 is set in playback mechanism 3
When the Y key is pressed, the system controller 7 controls the CD reproduction mechanism 3 and the signal processing unit 5 to start normal reproduction from the first music, and further, when the music forward key or the music return key is pressed, the TOC information is displayed. The search control of the head of the next music piece or the previous music piece is performed while collating the A-time of the subcode input from the signal processing section 5 with the sub-code, and normal search is started after the search is completed (steps 52 to 58). STOP during normal playback
When the key is pressed, playback stop control is performed to stop the playback of CD1 (steps 59 and 60). When the reproduction to the last music of CD1 is completed without pressing the STOP key, the reproduction is started by returning to the first music (step 6).
1,54. When the reproduction of the last song of CD1 is completed, CD1 may be replaced with that of the next disc and the first song may be reproduced. In addition to the normal reproduction described above, the reproduction other than the program reproduction performed by the CD player includes random reproduction in which the music is reproduced in a random music order, fast-forward reproduction, and fast-reverse reproduction.

[0037] During playback, based on the reproduction operation of the non-registration program playback operation of the program information, for example, such as during normal playback based on the PLAY key of the on-operation of the program playback mode off state, the registration / deletion key is pressed, the system The controller 7 checks whether there is an empty channel in the program file area 8C (steps 62 and 63), and since it exists, subsequently, the current disk NO storage area 8A of the built-in memory 7A at that time.
The disc number of the CD being reproduced is discriminated from the contents stored in the..., And the number of the currently reproduced tune is determined from the Q channel data input from the signal processing unit 5 (step 6).
4). Then, the disc number and the music number determined this time are combined and stored as the first program information in the channel with the smallest number among the available channels in the program file area 8C (step 65). For example, when the register / delete key is pressed during the reproduction of the second track of CD1 having disc No. = 2, disc No. = 2 and track number = 2 are registered as a combination of the CD and the track to be programmed in channel 1. (See FIG. 5A).

Similarly, the fourth track of the disc NO = 2,
When the registration / delete key is pressed during the reproduction of the first song of the disc NO = 5, the second song of the disc NO = 6,..., The program is sequentially registered in the second and subsequent channels of the program file area 8C (FIG. 5 (2)). reference). Thus, the user can
Like a changer player, even if there are a large number of CD1s to be programmed, the CD1 is reproduced by an operation other than the program reproduction operation, and the desired music can be heard while listening to the music to determine whether the music is the desired music. A simple operation of pressing the registration / delete key during that time, the CD containing the desired music
The disc No. 1 and the music number of the desired music can be registered accurately.

When a program is to be reproduced for each tune registered in the program reproduction destination, the STOP key is first pressed to stop the reproduction operation (steps 59 and 60), and then the program reproduction mode on / off key is pressed. Then, the system controller 7 turns on the program reproduction mode (step 66).
~ 68). Subsequently, when the program play operation is performed by pressing the PLAY key, the system controller 7 confirms that the program information is registered in one channel of the program file area 8A (steps 52 and 5).
3. Step 70 in FIG. 4) Program information of one channel = CD to be played back and information (combination of disc number and song number) for specifying music in the CD are read out, and the changer unit 4 is controlled. The disc is replaced with CD1 of disc No. = 2 registered in one channel, the current disc No. is stored in the current disc management area 8A, and the TOC information is read and stored in the TOC information storage area 8B (step 71).

Subsequently, search control of the head of the music number registered in one channel is performed, and after the search is completed, reproduction is started (step 72). After the reproduction of the first program tune is completed in this way, once stop control is performed (steps 73 and 74), and if the program information is registered for the second and subsequent channels, similar processing is sequentially performed. (Repetition of steps 75 to 77, 73, 74). As a result, among the CDs stored in the CD storage unit 2, it is possible to sequentially listen to the desired music of one or a plurality of desired CDs registered during the reproduction in the program reproduction mode off state.

When the reproduction to the last program information registered in the program file area 8C has been completed, the program returns to channel 1 and the program reproduction is repeated (steps 75, 70, 71, 72; the reproduction to the last program information is continued). When the reproduction is completed, the reproduction may be stopped and the process may return to step 50 in FIG. 3). If the STOP key is pressed during program reproduction, the system controller 7 performs reproduction stop control (steps 78 and 79), and returns to step 50 in FIG. If the PLAY key is pressed while the program performance mode is on with no program tune registered, the process returns to step 50 in FIG. 3 (in this case, the process proceeds to step 69 in FIG. 3 and automatically returns to step 69 in FIG. 3). The program playback mode may be turned off).

Returning to a playback state other than program playback After program playback, if you want to perform playback other than program playback, press the program playback mode on / off key.
Since the system controller 7 turns off the program reproduction mode, it is possible to reproduce any music on any CD 1 (see steps 66 and 67 in FIG. 3). However, even if the program playback mode is turned off or the power is turned off, the contents registered in the program file area 8C are not cleared. Therefore, even if the user does not perform the registration operation again, the program playback of the same contents will be performed later. Can be executed. In addition, if there is a new song to be added as a program song, it can be definitely added by simply operating the registration / delete key during playback.

Deletion of Program Information Even after registration in the program file area 8C, program music can be deleted in units of music. For example,
During program playback, if it is found that the song is not the desired song when the song of disc No. 5 and song number 1 is played, the registration / deletion key is pressed during playback of the song in the program playback mode. Then, the system controller 7 clears the channel related to the music being reproduced at that time, and if there is program information even after the next channel, moves up by one, thereby deleting the program information relating to the music being reproduced. (See steps 80 and 81 in FIG. 4 and FIG. 5 (3)). Thus, when the user wants to delete one or a plurality of unnecessary songs registered in the program and partially change the program contents, the user plays the program and presses the registration / deletion key while checking the unnecessary songs by ear. With a simple operation, you can undoubtedly make partial changes to the program contents. In this regard, conventionally, the program mode cannot be changed until the program mode is canceled and all the contents of the program file are cleared, and it is necessary to perform the registration operation again for the songs that do not need to be changed, which is very inconvenient. . In FIG. 4, although the reproduction of the current deleted music still continues after step 81 (step 73), if the process immediately proceeds to step 74 after step 81, the remaining part of the unnecessary music is not reproduced. I can do it.

In the above-described embodiment, one registration / deletion key is used for both the registration instruction operation means and the deletion instruction operation means in order to simplify the operation unit 6, so that the registration operation is performed during reproduction other than program reproduction. The deletion operation could only be performed during program playback.However, a registration key as a registration instruction operation means and a deletion key as a deletion instruction operation means were separately provided, and the registration key was pressed in any reproduction state. At the time, the program information including information for specifying the combination of the CD and the music being reproduced at that time can be registered, and when the delete key is pressed in any reproduction state,
At this time, the program information including the information specifying the combination of the CD being reproduced and the music may be deleted (however, the deletion during the reproduction other than the program reproduction may be carried out in the program file area by the currently reproduced CD and the program file). (Only when there is program information in which the disc number for specifying the music is combined with the music number).

In the above-described embodiment, the program is deleted one by one after the program is registered. However, for example, a batch deletion key different from the above-described registration / deletion key is provided, and the batch deletion key is pressed. Then, the contents of the program file area may be deleted all at once. Further, in the above-described embodiment, at the time of reproduction other than the program reproduction, the registration / deletion key is pressed while the desired music is being reproduced,
Although the combination of the CD and the music is registered as a combination to be programmed, the desired music and the undesired music have a front and back relationship. Therefore, in the opposite direction, a non-registration instruction key is provided so that the user can confirm from the music that is heard during the reproduction of a certain song on a certain CD that the song is undesired. Each time the non-registration instruction key is pressed, the system controller removes the combination of the CD and the song at that time as not the combination to be program-reproduced, and removes the remaining combination from the CD to be program-reproduced. As a combination of music pieces, information for specifying the combination may be stored in the program file area. However, if it is desired to simplify the processing, when the non-registration instruction key is pressed, the CD being reproduced and the disc N
The combination of O and the music number is stored as it is, and the combination of the CD and the music to be program-reproduced is stored indirectly. Then, at the time of program reproduction, the system controller may reproduce a combination of CD and music other than the combination directly stored in the program file area.

In the above-described embodiment and the modified example, C
Although the D changer player has been described as an example, the present invention is not limited to this.
The same can be applied to a player, and the same effect can be obtained. However, the CD player does not have a CD storage section, and only reproduces a desired piece of music in one CD at the time of program reproduction, so that there is no need to distinguish CDs. Therefore, only the music number may be stored as program information in the program file area. For example, if you have separate registration and deletion keys,
When the user who listens to the song being played and confirms that the song is the desired song and presses the registration key to perform a program registration instruction operation, the system controller determines the current playback song number from the Q channel information read from the CD, Only the program number is stored in the program file area. Thereby, the program of the desired music can be reliably executed by a simple operation. Conversely, even if it has been programmed, if the user presses the delete key and performs a program deletion instruction operation when listening to the song being played and confirming that it is an undesired song, the system controller will return the current playback song. The number is determined, and only the corresponding music number in the program file area is deleted. As a result, it is possible to surely execute a partial change of the program contents by a simple operation. When the CD is taken out, the program file area may be cleared in a lump.

When one registration / deletion key is used for both the registration key and the deletion key, the user who listens to the reproduced music and confirms that the music is the desired music during the reproduction according to the reproduction operation other than the program reproduction can hear the desired music. When the program registration instruction operation is performed by pressing the registration / delete key during the operation, the system controller determines the current reproduction music number from the Q channel information read from the CD, and stores only the music number in the program file area. When a user who listens to a reproduced song and confirms that the song is an undesired song during the program playback according to the program playback operation and presses a registration / delete key while the undesired song is being heard, the system performs a program deletion instruction operation. The controller determines the current playback track number,
Delete only the corresponding track number in the program file area. Thereby, both the registration instruction operation and the deletion instruction operation can be performed with one instruction key, and the configuration of the operation unit is simplified.

When the user who listens to the music being played back and confirms that the music is an undesired music is removed from the music when the user performs a non-registration instruction operation and registers the program numbers of the remaining music, the system controller Is previously stored in the program file area for each channel by referring to the TOC information in the program file area for each channel, and each time a non-registration instruction operation is performed during playback, the playback music at that time is read. And deletes it from the program file area. And
At the time of program reproduction, the system controller may reproduce the music left in the program file area.
This also makes it possible to reliably execute the program of the desired music by a simple operation, and to register the program with a small number of operations especially when there are many songs to be programmed.

Further, in the above-described embodiments and modified examples, the CD has been described as an example of the recording medium.
Video CD players, video CD changer players, minidisc systems, LD players, and other recording media such as D, MD, LD, and DAT tape cassettes.
It can also be applied to LD changer players, DATs, and the like. The recording medium is not limited to one in which music information is recorded in units of one song, but includes one track, one index (such as a CD), one entry (such as a video CD), one program, and one chapter (such as an LD). Music, video,
Even if other information is recorded alone or in combination, the same effect as described above can be exerted (in the case of a video, the current track or the current track or It is possible to confirm whether the program is a desired video).

Further, information such as music, video, etc. is not program-reproduced by unit information such as one song, one track, one index, one entry, one program, one chapter, etc. recorded on the recording medium, but is reproduced by each recording medium. The same can be applied to the case where the program is reproduced on a (recording medium unit) basis. For example, the present invention can be applied to a case where a CD changer player reproduces a program for each CD (CD unit).
In this case, there is no need to distinguish the songs on the CD. Therefore,
In the program file area, only the disc number specifying the recording medium is stored as the program information. For example, if you have separate registration and deletion keys,
When the user listens to the CD being played and confirms that the CD is the desired CD, and presses the registration key to perform a program registration instruction operation, the system controller determines whether or not the disc number in the memory
The current playback CD is determined from the information in the storage area, and only the disc number is stored in the program file area. Thus, the program of the desired CD can be securely executed by a simple operation. Conversely, even if it has been programmed, if the user listens to the CD being played and confirms that it is an undesired CD, and the user presses the delete key to perform a program deletion instruction operation, the system controller returns to the current playback CD. Is determined, and only the corresponding disk number in the program file area is deleted. As a result, it is possible to surely execute a partial change of the program contents by a simple operation.

When one registration / deletion key is used for both the registration key and the deletion key, the user who listens to the reproduced CD and confirms that the desired CD is heard during the reproduction operation according to a reproduction operation other than the program reproduction can hear the desired CD. When a program registration instruction operation is performed by pressing the registration / delete key during the operation, the system controller determines the current CD from the information in the disk NO storage area of the memory, and stores only the disk number in the program file area. If the user who listens to the reproduced CD and confirms that the CD is undesired during the program playback operation according to the program playback operation and presses the registration / delete key while the undesired CD is being heard, the system delete instruction is issued. Discriminates the current playback CD and deletes only the corresponding disc in the program file area. To. Thereby, both the registration instruction operation and the deletion instruction operation can be performed with one instruction key, and the configuration of the operation unit is simplified.

When the user who listens to the CD being played back and confirms that the CD is an undesired CD performs an unregistering instruction operation, removes only the CD, and program-registers the remaining CD's disk numbers. But beforehand
All disc Nos. n are stored in the program file area for each channel, and each time a non-registration instruction operation is performed during reproduction, the disc No. of the reproduced CD at that time is determined and deleted from the program file area. And
At the time of program reproduction, the system controller may reproduce the CD of the disc NO remaining in the program file area. With this, the desired C can be obtained with a simple operation.
The program D can be reliably executed, and particularly when there are many CDs to be programmed, registration can be performed with a small number of operations.
