Next, the conductive selection control method in the image flexible repeater according to an embodiment of the present invention shown in FIG. 3 will be described in detail.

First, the controller 50 determines whether the conductive mode is set in the corresponding image flexible repeater (step 60), and if it is determined that the conductive mode is not set in the corresponding image flexible repeater, the controller ( 50, the process proceeds to step 62, where the curve tack by the song trainee is waited.

In step 62, when the song practitioner selects a specific song number through the 10-key 41 provided in the key input unit 40, the controller 50 controls the TOC of the image flexible information source 2 previously stored in the RAM 54. By recognizing the information on the song through the information data and following the optical pickup device 10 based on the information, according to the background and lyrics for the song recorded in the video flexible information source (2) The video signal and the audio signal according to the accompaniment sound of the corresponding song may be read out, and the read video / audio signal may be video / audio-processed to reproduce the video / audio (step 64).

On the other hand, in step 64, the tracking degree of the voice signal of the song practitioner input through the microphone 4 for the accompaniment is detected, and the score of the song practitioner's song for the song is scored (step 66).

Subsequently, the controller 50 generates the OSD text signal for the score scored in step 66 through the OSD processor 56 and outputs the corresponding score on the monitor of the corresponding image flexible board cycler (step 68).

On the other hand, if it is determined in step 60 that the song practitioner selects the challenge mode through the key input unit 40, the controller 50 proceeds to step 70 according to the determination result of step 60 and the OSD processing unit 56 ), Enter the number of conductive songs on the monitor of the corresponding image flexible semi-cycler. While the OSD message is displayed, it waits for input of the number of challenge songs by the song practitioner.

On the other hand, when the number of conductive songs, for example, '10' is inputted by the 10-key 41 configured in the key input unit 40 (step 72), the controller 50 is stored in the image flexible information source 2. For example, random numbers are generated for '30' songs so that 10 songs are randomly selected among the '30' songs, and random numbers are generated in the selection order, and the order of the 10 songs is randomly determined (step 74). .

Thereafter, the controller 50 proceeds to step 76 to perform a playback operation on the first song among the ten songs, and the controller 50 reads information on the first song from the RAM 54. Based on the information, the video / audio signal of the first song is read from the video flexible information source 2, and then the video / audio signal is processed by video / audio processing, respectively.

Subsequently, the controller 50 determines whether 1 minute has elapsed based on the time data applied from the timer 52. If the playback time for the first song has passed 1 minute, the controller 50 performs a step. Proceeding to 80, the playback time for the next song is selected.

In step 80, the time information of the second song is read from the RAM 54 based on the order of the conductive songs determined in step 74, and the first 20 seconds of the previous pole is normally reproduced (ie, shown in FIG. 4). The middle 20 seconds (i.e., section (c) shown in Figure 4) and the latter 20 seconds (i.e., section (e) shown in Figure 4) In the playback section except for (i.e., (b) and (d) section shown in FIG. 4), a random number is generated so that the starting point can be made at an arbitrary time point, and the playing time for the second song is selected, and the second On the basis of the playback time selected for the song, a playback operation for the second song is performed (step 82).

After that, the controller 50 determines whether the playback time has elapsed for 30 seconds for the second subtitle based on the time data applied by the timer 52 (step 84). After 30 seconds have elapsed, the process proceeds to step 86 where it is determined whether the conductive song reproduced in the corresponding step 82 is the final conductive song.

On the other hand, if the conductive song reproduced in the step 82 is not the final conductive song, the controller 50 proceeds to the step 80 and repeatedly performs the operations from the above steps 80 to 84.

On the other hand, if the playback of the tenth song is performed in step 82 and the music reproduced in step 82 is determined as the final conductive song in step 86, the controller 50 according to the determination result in step 86 Proceeding to step 88, the conductive mode set in step 60 is canceled.

After that, the controller 50 proceeds to step 90 to play the final conductive song (i.e., the current song) reproduced in the step 84 to the end, and then proceeds to step 92 to start the final conductive song (from the first song of the conductive song) That is, scores for the overall challenge song are scored based on the tracker's voice signal of the song practitioner's voice signal with respect to the accompaniment sound detected by the tracker detection unit 26 during the playback up to the current song.

In addition, the controller 50 proceeds to step 94 and outputs the score for the conductive song scored in the step 92 on the monitor of the corresponding image flexible repeater.

As described above, according to the conductive music selection control method in the image flexible repeater according to an embodiment of the present invention, if the song practitioner selects the number of conductive songs in setting the conductive mode, randomly selects the number of conductive songs from the reproducible songs, and then random number. Selecting the playback order of the corresponding challenge song by generating a random number, generating the random number, selecting the playback section of each challenge song, and outputting the corresponding playback section. The song practitioner cannot expect it.

Therefore, when the challenge mode is selected in the image music processing cycler performing the above-described challenging music selection control method, not only the wits of the song trainees can be measured for an arbitrary song but also the interest and participation of the people around the game are improved. It can maximize the entertainment function.
