Next, the operation of the video flexible medium on which the score calculation code according to the present invention is recorded and the recording / reproducing apparatus will be described in detail.

First, when recording the accompaniment of the image flexible on a disc-shaped information recording medium applied as the image flexible medium 20, as described with reference to FIG. 1, a plurality of channels CH1 and CH2; When an accompaniment sound is input from an audio signal source (not shown) to a channel), the accompaniment sound is low-pass filtered by the low pass filters 1 and 2 for each channel to filter high frequency components. The accompaniment sound passing through the low pass filter (1, 2) is oscillated by the oscillator (3) and is divided by the timing signal part (4) based on the timing signal sample / hold part (5, 6).

This is then applied to the multiplex 11.

In addition, in consideration of the difficulty of accompaniment of the corresponding music information, each key (K0-K3) of the score data input unit 12 is operated to score points according to the silent section and difficulty level of the video song. By differently assigning, the score calculation code generation unit 13 generates a score calculation code sequence for assigning a score to the accompaniment sound of the video song according to the manipulation of the key (K0-K3). Applied to Part 14 Therefore, the score control code of the accompaniment sound, including the geocoding control and display encoding unit, is encoded and applied to the multiplex 11 and to the image flexible data modulator 16. The multiplex 11 time-multiplexes the control and display data including the accompaniment sound applied by the error correction unit 10 and the score calculation code applied by the control and display encoding unit 14 to perform the video flexible data. It is applied to the modulator 16. Therefore, the video flexible data modulator 16 includes the accompaniment sound and a score calculation code according to the synchronization signal applied from the synchronization signal generation unit 15 based on the timing signal provided from the timing signal 4. The image flexible data is modulated and output as image flexible information to be recorded on the image flexible medium 20, and the image flexible information is shown in FIG. 2A by means (not shown) for recording information on the image flexible medium 20. The image is recorded on the flexible media 20 in the data format shown in FIGS.

The accompaniment sound is recorded in the Q channel sub-code in the form of distinguishing between the songs by the P-channel when recording the image flexible information on the image flexible medium 20, while the score calculation code for the accompaniment sound is 2a. The mode and the item of is specified in the form (111 and 000) shown in FIG. 2b, and the command for commanding the score channel function is designated in the form (000 000) shown in FIG. 2c, and the score calculation for the accompaniment sound. As shown in FIG. 2D, the code specifies the non-scoring score for the silent section and the data of the upper, middle, and lower levels of the scoring operation according to the difficulty. Designation is made based on the operation of each key K0-K3 of the input unit 12.

Next, the reproduction of the video flexible medium in which the score calculation code is recorded will be described in detail.

First, when a playback operation is specified by inputting a selection, pitch, playback speed, etc. from the control input unit 46 to the video flexible medium 20 in which a score operation code is recorded in the data format shown in FIG. The video information is read from the flexible media 20. The digital signal processing unit 31 is digitally processed and the accompaniment sound is analog-converted by the data conversion unit 32 and then low pass filtered by the low pass filter 33, and the low pass filtered accompaniment sound is mixed with the mixing unit 34. It is buffered in the buffer 35 and then output. At this time, the voice signal of the flexible exerciser input from the voice input device 38 is low-pass filtered by the low-pass filter 39 and then applied to the amplifier 41 through the buffer 40, the recorder 41 The amplified audio signal is applied to the mixing unit 34 and mixed with the accompaniment sound reproduced by the image flexible medium 20 and output through the buffer 35.

On the other hand, the sub code (see FIG. 2) recorded on the video flexible medium 20 digitally processed by the digital signal processor 31 is read by the sub code reader 36 and then decoded by the data processor 37. Is processed and applied to the control unit 45, and accordingly, the control unit 45 performs the energy of the accompaniment sound and the voice signal digitally converted by the data conversion units 42 and 43 according to the clock signal provided from the clock generation unit 44. The difference is stored in the storage unit 47. The content stored in the storage unit 47 is the energy value of the grading code and the difference for the corresponding image interval as shown in FIG. Will be categorized into memory. As such, when the reproduction and audio input of the entire video song is completed, the control unit 45 calculates the score of the flexible exerciser based on the scoring code and the difference energy value stored in the storage unit 47. In this case, if the audio signal accurately follows the accompaniment sound based on the scoring code recorded corresponding to the accompaniment sound according to the difficulty level, the difference energy value becomes small, so that a high score is added, whereas the audio signal accompanies the accompaniment sound. If the sound is not accurately followed, the difference energy value becomes large, so that the low score is added. In addition, even when the difficulty level is low or low, if the audio signal accurately follows the accompaniment sound based on the scoring code recorded corresponding to the accompaniment sound, the difference energy value becomes small, so that a relatively high score is added. If the voice signal does not accurately follow the accompaniment sound, the difference energy value is increased so that a relatively low score is added. In this way, when the score calculation is performed for the entire video flexible section, the score is output to the image flexible output device 48 to inform the score of the flexible exerciser.

As described above, the score calculation based on the score calculation code is made possible in response to the silent section and the difficulty of the accompaniment sound of the video flexible medium according to the present invention, so that more accurate score calculation is performed and accordingly, flexible practice It is possible to secure video flexible exercises by more reliable products.
