The present invention relates to a song accompaniment method and a selected measure accompaniment method for calculating the score, and more specifically, to calculate the score by comparing the accompaniment data read from the recording medium and the sound of the user input by measure In response to the user's request for accompaniment of a particular measure, the accompaniment data to be played and the user's voice are played while the accompaniment data is played from the previous measure of the selected measure by selecting the particular measure. By comparing the scores by measure and calculating scores, and comparing and displaying the calculated scores after the completion of the predetermined measures, the user can easily recognize the vulnerable part of a specific song, and selectively and repeatedly play only the vulnerable part. The present invention relates to a song accompaniment method for scoring and an optional measure accompaniment method.

1 is a general configuration diagram of a video CD accompaniment (CDP) that performs a song accompaniment function, and includes a pickup section 10 for detecting a recording signal from the surface of a disc; A motor (M) for rotating the disk; A drive unit 13 driving the pickup unit 10 and the motor M; An R / F unit 12 for filtering the signal detected by the pickup unit 10; The servo unit 20 controls the driving of the drive unit 13 from the output signal of the R / F unit 12 and the rotational speed of the disc, and detects the synchronization of the output signal of the R / F unit 12. ); The digital signal processor 30 recovers the signal read out by the R / F unit 12 to the digital signal using the detected synchronization, and then restores the original video compressed data or music data (MIDI and lyrics data). ; An amp pack unit 31 for decoding the restored video compressed data; A memory 32 for storing MIDI data and lyrics data for music accompaniment of the restored song; A sound source ROM 40 in which sound source data corresponding to MIDI data is recorded; An on-screen display (OSD) 50 for converting and outputting lyrics data stored in the memory 32 into a video text signal; A sound source output unit 60 for receiving the MIDI data stored in the memory 32 and reading out the sound source data recorded in the sound source ROM 40; An A / D converter 70 for converting and outputting the user's sound input through the microphone Mic into digital data; And a microcomputer (MICOM) 100 that calculates a score of the converted user song based on an output time of the sound source output unit 60 of the accompaniment data of the memory 32.

In the video CD half-cycle configured as described above, when the user selects a song list by key input, the microcomputer 100 starts from the playlist information of the MIDI CD already read and stored in the memory 32. After controlling the drive unit 13 to move the pickup unit 10 to the corresponding track, the music unit of the song list selected from the music data (MIDI and lyrics data) information area on the MIDI CD, the pickup unit 10 ) And the detected high frequency signal is filtered by the R / F unit 12. The filtered shaping signal is a synchronization signal detected by the servo unit 20, the digital signal processing unit 30 is a music from the filtered signal by the synchronization signal detected by the servo unit 20 Data is restored and stored in the memory 32 under the control of the microcomputer 100.

Thereafter, when the user requests a playback, the microcomputer 100 controls the drive unit 13 to move the pickup unit 10 to the image information area on the MIDI device in the same process as above. The image data detected by the digital signal processing unit 30 and restored by the digital signal processor 30 is transmitted to the amp pack unit 31, and the image data transmitted to the amp pack unit 31 is decoded and decoded and output as a video signal. It starts to print.

On the other hand, the MIDI data transmitted and stored by the microcomputer 100 to the memory 32 is input to the sound source output unit 60, the sound source output unit 60 is the sound source data corresponding to the input MIDI data to the sound source Accompaniment is performed by outputting each sound source by searching in the ROM 40, and the on-screen display 50 is a time (output time) in the midi data in which the microcomputer 100 is stored in the memory 32. And converts the lyrics input according to the video signal into a video text signal, and converts the lyrics into a color signal of the text. The signal is synthesized with the video signal decoded and output by the amplifier unit 31. The progress of the lyrics is displayed in the background image.

By the above-described process, the user sings the song for the selected song according to the accompaniment while watching the video and the row of artists. During this process, the microcomputer 100 is input through a microphone and the A / D converter 70 In this way, the score is calculated by comparing the intensity of the user's sound converted into digital data with the time and height of the sound being read out based on the beat (output time) in the media data in the memory 32. The score is calculated until the accompaniment for a song is finished, and after the completion of the song, the score is input to the on-screen display 50 so that the synthesized output is output together with a background image. I noticed the score.

However, in the score calculation and display method for the above-described song, since the score is calculated and displayed once after the completion of the song for the user's song, the user can know the overall ability of the song. The calculated score does not know which part of the song is vulnerable, so it is inappropriate to improve the singing ability of a particular song, and it is judged to be vulnerable by itself, and it is requested to repeat the playing of the song to practice the vulnerable part. Even if a song is played as a whole, unnecessary time is wasted in practicing the song, and in this way, the user cannot feel whether the singing ability has been improved for the vulnerable part, and the user feels frustrated, thus calculating the overall score. By the way, it's almost impossible to improve your singing There was a problem that was impossible.

Therefore, the present invention was created in order to solve the above problems, by calculating the score for each song of the input user by the score, so that the user can easily recognize the vulnerable portion of his song Its purpose is to provide a method of accompaniment for song production.

In addition, the present invention by playing back and forth accompaniment when the user selects a particular measure and at the same time re-calculate the score for the corresponding measure to display the comparison with the previous score, so that the user can directly check whether their weakness is improved There is another purpose in providing an optional measure accompaniment method.

Hereinafter, the flow of the song accompaniment method of score calculation according to the present invention will be described in detail with reference to the configuration of the video CD half cycle of FIG. 1. do.

In the song accompaniment method of score calculation according to the present invention, the user first selects a song on the microcomputer 100 through key input (S1), and inputs a specific reference score for display (S10). When the song is selected as described above, the microcomputer 100 moves the pickup unit 10 as described above, reads the MIDI and lyrics data for the selected song from the disc, restores the digital data, and restores the digital data. It stores in the memory 32.

By the same process as described above in the prior art is the playback of the selected song is made (S11), so that the user sings the song for the selected song piece in accompaniment while watching the video and a row of photos, The microcomputer 100 compares the beat and pitch of the MIDI data previously stored in the memory 32 with the beat and the intensity of the sound input through the microphone, and calculates a score according to the match. At this time (S12), the microcomputer 100 calculates the score in units of measure every time a measure code in the lyrics data read out from the memory 32 in accordance with the beat (S12), when the accompaniment of the corresponding measure It is stored in a specific area of the memory 32 in association with the sequential measure number (S13).

In addition, in storing the calculated score for each measure, only the corresponding measure and a corresponding measure score for which a score less than or equal to a score input by a user is calculated through the microcomputer 100 may be stored in the memory 32. .

The score calculation and the score storage for each measure are continuously performed until the end of the accompaniment of the song selected by the user, and when the accompaniment of the song ends (S21), the microcomputer 100 stores the measures stored in the memory 32. Among the scores of the stars, the user is the lowest value by outputting the measure and the score corresponding to the score below the reference score set in the previous step (S10) to the on-screen display 50 to be synthesized with the background image You can see the measure that is below the score set as the level so that you can easily recognize the vulnerable part of the song you sang.

Unlike the method of displaying the corresponding measures as described above, the microcomputer 100 calculates the average score of each calculated measure score at the end of playback of the song, and then calculates the corresponding score and score of less than the calculated average score. In addition, the average score for each measure may be displayed on the screen so that the user may recognize a relatively vulnerable measure and its degree of weakness.

FIG. 3 is a flowchart of a selection measure accompaniment method according to the present invention. Hereinafter, the flow of the selection measure accompaniment method of FIG. 3 according to the present invention will be described in detail with reference to the configuration of the video CD half cycle.

As shown in the embodiment of FIG. 2, when the user recognizes a weak measure part of the song she sang from the result of displaying the score for each measure, and thus selects and inputs a specific measure to be played repeatedly through the microcomputer 100. In operation S31, the microcomputer 100 reads the music data from the portion of the music data previously read in the memory 32 corresponding to a predetermined measure before the selected measure, and reproduces the music data as described above. (S32). In this way, the accompaniment starts before the measure in order to be able to perform enough singing ability in the selected measure.

While the song is being played as described above, when the accompaniment of the selected corresponding measure is performed, the micom 100 recalculates the score of the corresponding measure as described above with respect to the input sound of the user, and the calculated score and the corresponding. After the measures are newly stored in a specific area of the memory 32 (S33), the accompaniment process is performed until the playback ends for the before and after specified N measures including the measures selected by the user, and playback is performed until after the selected measures. When it is finished (S41), the microcomputer 100 compares and outputs the newly calculated and stored measure scores and the scores stored by the previous song with respect to the selected playback measures (S42). It is to immediately recognize whether or not the singing ability is improved for the measure determined as a weak measure.

The song accompaniment method and the selected measure accompaniment method of the score calculation according to the present invention made as described above, by comparing the score by the measure based on the MIDI data for the user's specific song input, the user By easily recognizing the vulnerable part of the song and selectively singing the measure accordingly, it is possible to immediately know whether the singing ability of the song has been improved, thereby eliminating unnecessary wasted time for practicing the song. By repeatedly practicing only the vulnerable parts of the song, it is a very useful and convenient invention that can improve the singing ability of a particular song more interestingly and easily.
