It includes.

The microcomputer 11 inputs a predetermined key input signal output from an external key input unit 40, and unnecessary Midi data among Midi data in which the input key input signal is stored in the memory element 12 or 13. In the case of a signal for erasing the signal, the first or second control signal CS ₁ (CS ₂ ) for erasing Midi data for unnecessary songs among the songs stored in the memory device 12 or 13 is stored in the memory. Output to element 12 or (13).

In addition, when a key input signal for storing a desired song in the memory 13 among the songs stored in the memory device 12 is input, the microcomputer 11 stores the existing song stored in the memory device 12. After outputting the first control signal CS ₁ for reading and storing the Midi data for the desired song in the memory device 12, the Midi data read from the memory device 12 is then read. The second control signal CS ₂ is output to the memory device 13 for output and storage.

In addition, when a key input signal for outputting Midi data through the monitor 20 and the speaker 30 is selected by selecting a desired song from existing or additional songs stored in the memory device 12 or 13. The microcomputer 11 stores a first or second control signal CS ₁ (CS ₂ ) for reading Midi data for a desired song from the memory element 12 or 13 and storing it in the internal memory. Output to element 12 or (13).

The memory element 12 is the Midi data for the songs stored in advance is capable of ^{E 2 PROM (Eelectrically Erasable Programmable ROM} ) and read out as a write-existing music memory element mounted within the set during CMP produced is used.

The memory device 13 is an additional song memory device for storing Midi data for a new song to be added when a new song is to be stored while using CMP. The memory element 13 is stored in the CMP set without Midi data being stored. E ² PROM is installed and can be written and read.

The CMP apparatus of the present invention further includes an external third memory element 18 for providing Midi data for the additional song from the outside to the second memory 13, which is an additional song memory element for storing the additional song. .

The third memory element 18 is an E ² PROM capable of writing and reading as an additional song pack in which Midi data for additional songs not stored in the first memory element 12 is stored.

Accordingly, the Midi data for the additional song stored in the third memory device 18 is deleted or the second part of the first or second memory 12 (13) that is unnecessary in accordance with the third control signal CS ₃ . It can be stored further in the memory 13.

At this time, the microcomputer 11 has a signal for storing additional songs stored in the external third memory 18 in the first memory element 12 or the second memory element 13 mounted in the CMP set. 40, a third control signal for outputting to the third memory element 18 in accordance with this key input signal to read out the Midi data for the desired song from the third memory element 18 and to store it in the internal memory. CS ₃ ) is output to the third memory element 18, and then Midi data for additional songs read from the third memory element 18 is stored in a portion where unnecessary songs of the first memory element 12 are removed. In order to output the first control signal CS ₁ to the first memory element 12 or to store it as an additional song, the second control signal CS ₂ is transmitted to the second memory element 13. Outputs

In addition, the CMP of the present invention further includes an external fourth memory device 19 for storing a desired song in an external memory device among songs stored in the first memory device 12 or the second memory device 13. can do.

The fourth memory element 19 is an external additional song pack, and is installed outside the CMP set unlike the second memory element 13 or the additional song storage for storing the additional song like the second memory element 13.

In addition, the fourth memory device is installed at the position where the third memory device 18, which is an additional song pack in which Midi data for additional songs is stored, is installed in the karaoke system.

This memory element 19 is not for storing Midi data for additional songs like the third memory element 18, but for storing additional songs like the second memory element 13 mounted in the CMP set. ² PROM is used.

Therefore, when the third memory element 18 that is an external additional song pack is used, the Midi data of the additional song stored in the third memory element 18 is transferred to the first or second memory element 12 (in the CMP set). In the case of using the fourth memory element 19, which is an additional additional song storage, the Midi data of the song stored in the first or second memory element 12, 13 can be stored. It may be stored in the external fourth memory device 19.

That is, Midi data about a song may be interchanged and stored between a memory element inside the CMP set and a memory element outside the CMP set.

In the karaoke system of FIG. 1, when a user selects a song stored in a CMP set using the key input unit 40, the microcomputer 11 reads the Midi data from the memory element, and the caption data is transferred to the subtitle signal generator 14, The accompaniment zeta outputs to the accompaniment controller 15.

The caption signal generator 14 receives the caption data among the Midi data to generate the caption signal, and the adder 16 adds the caption signal output from the caption signal generator and the background image signal applied from the video player to the monitor 20. Output

On the other hand, the accompaniment data is applied to the adder 17 through the accompaniment controller 15 is added to the voice signal through the MIC is output to the speaker 30.

Therefore, a background in which subtitles are displayed through the monitor 20 is displayed and a voice signal is output through the speaker 30.

Hereinafter, operations of deleting Midi data of an existing song or storing Midi data of an additional song will be described with reference to FIGS. 2 to 5.

First, referring to FIGS. 2 and 5, additional songs stored in an additional song pack, which is a third memory element 18 installed outside the CMP set 10, are added as the second memory element 13 inside the CMP set. The operation of sequentially storing the song storage memory will be described.

2 is a flowchart of an operation of storing an additional song stored in the third memory element 18 outside the CMP set in the second memory element 13 inside the CMP set, and is external to the CMP set from the external key input unit 40. When a predetermined key for sequentially storing desired Midi data is sequentially input from the third memory element 18 of the CMP set to the first memory element 13 of the CMP set, the microcomputer 11 firstly generates a third control signal. The data amount of the additional song is read using The amount of data that can be stored in the second memory element as the additional song storage is read using the call.

Then, the data amount of the read additional song is compared with the storage function data amount of the second memory, and if the additional song data amount is larger than the amount of data that can be stored, it is treated as an error.

In the small case, the microcomputer 11 generates a third control signal. Outputs the Midi data for the first of the songs stored in the third memory device 18, reads from the third memory device 18, and stores them in its own memory.

That is, the microcomputer 11 generates a chip select signal as shown in FIG. To select the third memory element 18, and also to the third memory element 18, a read control signal as shown in Figs. 5 (C) and (E). And outputs the address signal ADDR A, reads the Midi data for the additional song as shown in FIG. 5 (F) stored at the corresponding address ADDR A, and stores it in its own memory.

After that, the microcomputer 11 generates a second control signal. The additional song Midi data from the additional song pack 18 stored in its own memory is output to the second memory element 13 in the set and stored in the second memory element 13.

That is, the microcomputer 11 generates a chip select signal as shown in FIG. 5 (B). To select the second memory element 13, and the microcomputer 11 write-control signals such as the fifth (D) and (E). And the address signal ADDR B are output, and the additional music Midi data stored in the microcomputer 11 is written into the address ADDR B as shown in FIG.

Therefore, the additional songs stored in the set external third memory element 18 are sequentially transferred to the second memory element 13 for storing additional songs in the set and stored one by one by the above operation.

If you save all the additional songs you want in this repetitive operation completes the additional song storage operation.

Therefore, by reading the contents of the external additional song pack and storing it in the additional song storage in the CMP, the external additional song pack becomes unnecessary, and if the additional song pack is continuously replaced with a new pack, the data volume of the additional song storage may continue to increase. As a result, new songs can be added to the CMP as long as the additional song storage capacity is allowed.

Second, among the songs stored in the second memory element 13, which is an additional song storage in the set, or the first memory element 12, which is an existing song storage, the Midi data for unnecessary songs are deleted, An operation of storing new additional songs again using the additional song pack will be described with reference to FIG.

3 is a diagram showing an additional song stored in the additional song pack 18 after deleting unnecessary songs from among songs stored in the second memory element 13, which is an additional song storage in the CMP set, or the first memory element 12, which is an existing song storage. This is a flowchart showing the operation of storing a song.

First of all, when an unnecessary song is to be deleted from songs stored in the second memory device 13 or the first memory device 12, a song number to be deleted is selected using an external key.

The microcomputer 11 inputs the number of the selected song and inputs the existing song stored in the first memory element 12 in the CMP set 10 or the second memory in the CMP set 10. It is determined whether or not the additional music is stored in the element 13.

If the song to be deleted is one of the existing songs, the Midi data of the selected song stored in the first memory device 12 is deleted using the first control signal CS ₁ .

On the other hand, if the song to be deleted is one of the additional songs, the Midi data of the selected song stored in the second memory element 12 is deleted using the second control signal CS ₂ .

If there are songs to be deleted after the selected deletion, the above operation is repeatedly performed to delete them.

After all the selected songs are deleted, it is determined whether to store additional new songs at the deleted location. If the new songs are not stored additionally, the delete operation is completed and additionally, the new songs of the additional song pack 18 are additionally stored. If you want to, select a new additional song number using a foreign key.

Subsequently, it is determined whether to store the new additional song at the position where the existing song is deleted or at the position where the additional song is deleted.

When a desired song is stored as a new additional song among the songs stored in the third memory device 18, which is an additional song pack outside the CMP set, in the first memory device 12 from which the existing song is deleted, new addition is performed using the third control signal. The data amount of the song is read out, and then the total data amount of the existing songs deleted, that is, the total amount of data that can be stored in the first memory element 12, is read out using the first control signal.

Is smaller than the data amount and the total amount of data available amount of storage data of the stored total amount of data compared to add new songs available a new more songs for new added using a third control signal (CS _3), as described in the second Fig. After the music is read from the third memory device 18, the existing music of the first memory device 12 is stored in the deleted position using the first control signal CS ₁ .

On the other hand, if the data amount of the new additional song is larger than the total amount of data that can be stored, an error occurs because the memory capacity of the first memory element 12 is insufficient to store additional new songs.

On the other hand, when a new additional song is to be added to the second memory element 13 from which the additional song is deleted, the third memory which is an additional song pack outside the CMP set 10 using the third control signal CS ₃ . The data amount of the selected new additional music stored in the element 18 is read out, and then the total data amount of the deleted additional music is read out using the second control signal CS ₂ .

If the data amount of the new additional song is large compared to the total data amount of the deleted additional songs, an error occurs because the memory capacity of the second memory element 12 is insufficient to store additional new songs.

If the data amount of the new additional song is smaller than the total data amount of the deleted additional songs, the Midi data of the new additional song is read out from the external third memory element 18 by using the third control signal CS ₃ . The new additional song is newly written (stored) at the position where the additional song of the second memory element 13 is deleted using the second control signal CS ₂ .

As described above, when a new additional song is to be stored in the first memory element 12 or the second memory element 13 and another new song is to be stored, select a foreign key or the like to add a new song number. After selecting, repeat the above operation, and if there are no additional songs to be stored, the operation of storing new additional songs is completed.

Midi data reading and Midi data storage of the song are performed in the same manner as described in FIGS.

4 is a flowchart illustrating a case in which music stored in a memory device inside the CMP set is stored in a memory device outside the CMP set.

When storing songs stored in memory elements inside the CMP set in memory elements outside the CMP set, additional song packs outside the CMP set are stored in the fourth memory element 19 in the first memory element 12 or the second inside the CMP set. The music stored in the memory device 13 is stored.

At this time, the additional song pack outside the CMP set is configured to E ² PROM, and to store additional songs sequentially, such as the second memory element 13, which is an additional song storage in the set, and the external additional song pack in which the additional songs are stored. (18) is installed instead.

The operation of storing the songs stored in the memory elements 12 or 13 inside the CMP set of FIG. 4 in the fourth memory elements 19 outside the CMP set may include storing the songs outside the CMP set of FIG. 3 in the memory inside the CMP set. This is the opposite of the operation to store in the device.

In FIG. 3, new songs are written at the positions after deleting the songs stored in the memory elements of the CMP set. In FIG. 4, additional songs are sequentially written to separate additional song packs.

Therefore, only the desired song is selected from among the songs contained in the CMP set using an external key and the like is read using the first or second control signal, and then the Midi data of the song is transmitted to the additional song pack using the third control signal. The additional song pack will only contain the selected songs.

Therefore, this pack can be used in another CMP as the third memory element 18 to store the same method as in FIG. 2 in the second memory element 3, which is an additional song reservoir inside another CMP set.

In addition, all additional songs stored in the additional song storage 13 may be sequentially stored in the additional song pack 19, which is an external additional song storage, and all of the existing songs stored in the existing song storage 12 are sequentially added external song packs. You can also store in (19).

The operation in this case proceeds based on the flow chart as in FIG.

On the other hand, in the present invention, it is possible to exchange and store Midi data for a song between the memory elements 12 and 13 in the CMP set by the data read and write operations as described above.

According to the present invention as described above, not only unnecessary songs can be deleted among the songs stored in the set, but also new external songs can not be additionally stored in the deleted position.

In addition, a separate additional song storage can be installed inside the set to store additional new songs contained in an external additional song pack, as well as storing songs stored in a memory device inside the CMP set in a separate external additional song pack. It can also be used as an additional song pack to other CMPs.

Therefore, in the conventional karaoke system with a built-in CMP, only songs that were already embedded could be used, and in order to use the new song, the karaoke system with a built-in CMP had to be purchased again, but in the same manner as in the present invention. The new song can be changed freely, maximizing the use of the karaoke system.
