A program for executing (described later) is included. Reference numeral 33 denotes a RAM having a work area and a data area. In the work area of the RAM 33, various register / flag data necessary for executing communication processing and dance processing are temporarily stored. Various data used for dance processing are stored in the data area of the RAM 33. Here, the contents of various data stored in the data area of the RAM 33 and used for dance processing will be described with reference to FIG.
[0019]
In FIG. 5, the music data download area MDDE stores music data MD (see FIG. 3A) downloaded from the server 1 side. The step data download area SDDE stores step data SD (see FIG. 3B) downloaded from the server 1 side.
In the pattern data group PDG, various accompaniment patterns (0) to (N) are stored in advance. Each of the accompaniment patterns (0) to (N) includes an event ET indicating the pitch of the accompaniment sound, the type of rhythm sound or accompaniment chord, and the time T indicating the sounding timing in the order of time-series addresses according to the progression of the music. Data END representing the end of the song is provided at the end. The accompaniment pattern corresponding to the pattern number included in the music data MD stored in the music data download area MDDE is selected from the pattern data group PDG. For this reason, it is not necessary to download the accompaniment pattern from the server 1 side to the terminal 3 side, and the amount of data to be downloaded can be reduced.
[0020]
The pose image group PI stores in advance various pose image data for displaying a model posture for each dance step on the screen. Specifically, as shown in the example illustrated in FIG. 6, the model performance is composed of image data obtained by capturing an exemplary performance by a male and female pair for each dance step. The pose image data is classified and stored in various dance types. The pose image data designated by the pose image identification data ED1 in the step event ST included in the step data SD stored in the step data download area SDDE is selected from the pose image group PI. For this reason, it is not necessary to download various pose image data for displaying a model posture for each dance step from the server 1 side to the terminal 3 side, and the amount of data to be downloaded can be reduced.
[0021]
The step graphic image SI is image data for displaying the footsteps of both men and women. Specifically, as shown in the example shown in FIG. 6, a set of feet representing the positions of both the left and right feet of men and women. It consists of mold image data. The step graphic image SI is the male right foot position data ED2, the male left foot position data ED3, the female right foot position data ED4 and the female left foot position data ED5 during the step event ST included in the step data SD stored in the step data download area SDDE. As a result, the display position in the display screen is changed. Therefore, it is not necessary to download the step graphic image SI from the server 1 side to the terminal 3 side in accordance with the change of the pose image, and the amount of data to be downloaded can be reduced.
[0022]

A communication unit 37 communicates with the server 1 via the relay station 2 under the control of the CPU 31.
[0023]
B. Operation of the embodiment
Next, the operation of the distribution system will be described with reference to FIGS. In the following, as a schematic operation of the entire system, the communication process is first described with reference to a sequence flow, and then each operation of “dance process” and “step image change process” executed by the terminal 3 is described.
[0024]
(1) Operation of communication processing
When the terminal 3 is powered on and initialization for initializing each unit is completed (step S1), the process proceeds to step S2, and the terminal 3 determines whether or not the communication switch is turned on. Here, it is assumed that the user has turned on the communication switch in order to download content necessary for the dance lesson from the server 1. If it does so, the judgment result of step S2 will be "YES", it progresses to step S3, and the connection process which establishes communication with the server 1 via the relay station 2 is performed. In this connection processing, access authentication data including a user ID and a password is transmitted from the terminal 3 side to the server 1 side, the server 1 performs access authentication in response to this, and when the server 1 authenticates as a regular user, the server 1 Establish a connection with. When the connection with the server 1 is established, the terminal 3 proceeds to step S4 and sends a music list request signal.
[0025]
When the server 1 receives the song list request signal from the terminal 3, it creates a song list screen for displaying a list of song data groups MDG stored and managed as its own database (step S5). It returns to the terminal 3 that sent the signal (step S6). Then, the terminal 3 displays the song list screen sent from the server 1 side on the display unit 34 in step S7. Next, in step S8, the music data MD to be downloaded is selected from the music list screen displayed on the screen, and in the subsequent step S9, a music request signal for requesting download of the selected music data MD is sent to the server 1.
When the server 1 receives the song request signal from the terminal 3, the server 1 proceeds to step S10 and searches the song data group MDG for the song data MD specified by the song request signal. Next, in step S11, step data SD corresponding to the music data MD searched in step S10 is searched from the step data group STG. Thereafter, the process proceeds to step S12 in FIG. 8, and the searched music data MD and step data SD are sent to the terminal 3 that has issued the music request signal.
[0026]
As a result, the terminal 3 downloads the content (music data MD and step data SD) requested in step S13, stores the music data MD in the music data download area MDDE of the RAM 33, and stores the step data SD in the step data download area SDDE. To do. When the music data MD and the step data SD have been stored, the determination result in step S14 is “YES”, the process proceeds to step S15, and a dance process (to be described later) for performing a dance lesson based on the downloaded music data MD and the step data SD is performed. Execute.
[0027]
If the terminal 3 is downloading, the determination result in step S14 is “NO” in the terminal 3, and the process proceeds to step S16. For example, the terminal 3 performs other processes such as displaying the status of how much the download is in progress. Thereafter, the process returns to step S2 in FIG. 7 to determine whether or not the communication switch is turned on.
Here, for example, when the download is completed and the user turns off the communication switch, the determination result in step S2 is “NO”, and the process proceeds to step S14 in FIG. In this case, since the music data MD and the step data SD have already been stored, the determination result in step S14 is “YES”, and a dance process (described later) is executed via step S15.
[0028]
(2) Dance processing operation
Next, with reference to FIG. 9 to FIG. 15, the operation of the dance process executed in the terminal 3 will be described. It is assumed that the dance process is executed in step S15 (see FIG. 8) of the sequence flow described above. Then, the CPU 31 of the terminal 3 determines whether or not the start switch for instructing the start of the dance lesson and the stop switch for instructing the stop of the dance lesson in steps SA1 and SA2. In the following, each operation will be described by dividing into “operation at the start of learning”, “operation during the learning” and “operation at the stop of learning” according to the operation of the start switch / stop switch.
[0029]
(1) Operation at the start of training
It is assumed that the user turns on the start switch to start the dance lesson. If it does so, the judgment result of step SA1 will be "YES", it will progress to step SA3, and flag value "1" showing a training start will be set to start flag STF. In step SA4, the pattern number n included in the music data MD stored in the music data download area MDDE of the RAM 33 is read. Subsequently, in step SA5, an accompaniment pattern address pointer is set at the head address of the accompaniment pattern (n) designated by the pattern number n in the pattern data group PDG of the RAM 33. In step SA6, the music address pointer is set at the head address of the SMF included in the music data MD stored in the music data download area MDDE. Next, at step SA7, a step address pointer is set to the head address of the step data SD stored in the step data download area SDDE of the RAM 33.
[0030]
Thus, when the accompaniment pattern address pointer for reading the accompaniment pattern, the music address pointer for reading the SMF, and the step address pointer for reading the step data SD are set to the respective leading addresses, the CPU 31 performs the processing shown in FIG. Steps SA8 to SA14, SMF reproduction, step SA15 to step SA19, accompaniment pattern reproduction, and step SA20 to step SA23, initial image display. In the following, the operations of “SMF playback”, “accompaniment pattern playback” and “initial image display” will be described separately.
[0031]
a. SMF playback
After the music address pointer is set at the head address, when the process proceeds to step SA8 in FIG. 10, the CPU 31 reads out the head data of the SMF according to the music address pointer. Next, in step SA9, it is determined whether the read data is time T or event ET. Since the head data of the SMF is an event ET, the process proceeds to step SA10, and it is determined whether or not the read event ET is code data based on a meta event. If the read event ET is code data based on a meta event, the determination result is “YES”, the process proceeds to step SA11, the code data is set in the register CODE, and the process proceeds to step SA13.
[0032]
On the other hand, if the read event ET is a normal note-on event, the determination result in step SA10 is “NO”, and the process proceeds to step SA12 to generate a musical tone having a pitch specified by the note-on event. The sound source 35 is instructed. Thereby, the terminal 3 reproduces the first performance sound in the SMF. Thereafter, the CPU 31 proceeds to step SA13, increments the music address pointer and increments it, and then returns to step SA8 to read the time T from the SMF in accordance with the incremented music address pointer. When the time T is read, the process proceeds to step SA14, and the time T is set in the register T1. Hereinafter, the content of the register T1 is referred to as a music time T1.
[0033]
b. Accompaniment pattern playback
When the first performance sound is reproduced in this way, the CPU 31 advances the process to step SA15, and reads the head pattern data in accordance with the accompaniment pattern address pointer. Subsequently, in step SA16, it is determined whether the read data is time T or event ET. Since the top data of the accompaniment pattern data is the event ET, the process proceeds to step SA17 to instruct the sound source 35 to generate the accompaniment sound specified by the event ET. Thereby, the terminal 3 reproduces the first accompaniment sound in the accompaniment pattern. Next, in step SA18, the accompaniment pattern address pointer is incremented and advanced. Thereafter, the process returns to step SA15, and the time T is read from the accompaniment pattern in accordance with the stepped pattern address pointer. When the time T is read, the process proceeds to step SA19, and the time T is set in the register T2. Hereinafter, the contents of the register T2 are referred to as accompaniment time T2.
[0034]
c. Initial image display
When the first accompaniment sound is thus reproduced, the CPU 31 proceeds to step SA20 shown in FIG. 11, and reads the leading time T from the step data SD in accordance with the step address pointer. In step SA21, the read time T is set in the register T3. Hereinafter, the contents of the register T3 are referred to as step time T3. Next, at step SA22, the step address pointer is incremented to be incremented, and at step SA23, the step event ST is read from the step data SD in accordance with the incremented step address pointer.
[0035]
In step SA24, the corresponding pose image data is read from the pose image group PI (see FIG. 5) of the RAM 33 in accordance with the pose image identification data ED1 included in the read step event ST, and is displayed on the display unit 34. Step graphic images SI representing the respective footsteps are displayed according to the display positions specified by male right foot position data ED2, male left foot position data ED3, female right foot position data ED4 and female left foot position data ED5 included in step event ST. The screen is displayed on the unit 34.
[0036]
▲ 2 ▼ Operation during dance lesson
As described above, the performance sound and the accompaniment sound start to be reproduced, and when the pause image and the step graphic image are displayed in synchronization therewith, the CPU 31 advances the process to step SA1 in FIG. Judgment is made. When the dance training is in progress, since the start switch is already set to the on state, the determination result is “NO”, and the process proceeds to Step SA2. In step SA2, it is determined whether or not the stop switch is turned on. However, since the stop switch is not turned on during the dance lesson, the determination result is “NO”, and the process proceeds to step SA25 shown in FIG. In step SA25, it is determined whether or not the start flag STF is “1”, that is, whether or not dance learning has been started. In this case, since the start flag STF is set to “1” by the start of the dance lesson, the determination result is “YES”, and the flow proceeds to the next step SA26.
[0037]
In step SA26, it is determined whether the minimum unit time has elapsed. That is, the CPU 31 generates a tempo clock corresponding to the playback tempo by a timer interrupt process (not shown), and determines whether or not the minimum unit time for one cycle of the tempo clock has elapsed. If the minimum unit time has not elapsed, the determination result is “NO”, and the process returns to step SA1 shown in FIG.
On the other hand, if the minimum unit time has elapsed, the determination result in step SA26 is “YES”, the process proceeds to steps SA27 to SA29, and the music time T1, accompaniment time T2, and step time T3 are decremented.
[0038]
In step SA30 and subsequent steps, processing is performed when the decremented music time T1, accompaniment time T2, and step time T3 reach “0”, that is, the music playback timing, accompaniment playback timing, and image update timing, respectively. Hereinafter, each operation of “when the music playback timing has been reached”, “when the accompaniment playback timing has been reached”, and “when the image update timing has been reached” will be described.
[0039]
a. When the music playback timing is reached
When the music time T1 that is decremented at every elapse of the minimum time becomes “0” and the music playback timing is reached, the judgment result at step SA30 becomes “YES”, the process proceeds to step SA31, and the music address pointer is incremented to increase the step. Advance. Next, in step SA32, data is read from the SMF according to the stepped music address pointer. In step SA33 and subsequent steps, processing corresponding to the read data type is executed. Hereinafter, processing in each case where the data type read from the SMF is “time T”, “event ET”, and “data END” will be described.
[0040]
<In case of time T>
If the data read from the SMF is time T, the determination result in step SA34 is “YES”, the process proceeds to step SA35, the time T is stored in the register T1, and the music time T1 is updated. Proceed to step SA40.
[0041]
<In case of event ET>
If the data read from the SMF is the event ET, the process proceeds to step SA36 shown in FIG. In Step SA36, it is determined whether or not the event ET is code data based on a meta event. If it is code data based on a meta event, the determination result is “YES”, and the process proceeds to step SA37, where the code data is set in the register CODE, and then the process proceeds to step SA39.
On the other hand, if the event ET is a normal note-on / note-off event, the determination result in step SA36 is “NO”, the process proceeds to step SA38, and the processing corresponding to the event, that is, the pitch specified by the event. The sound source 35 is instructed to sound (or mute) the musical sound. Thereby, the performance sound by SMF is reproduced. Thereafter, the process proceeds to step SA39, where the music address pointer is incremented and stepped, and then the process returns to step SA32 in FIG. 12 to read the next data from the SMF.
[0042]
<For data END>
If the data read from the SMF is data END indicating the end of the song, the determination result in step SA33 shown in FIG. 12 is “YES”, and the process proceeds to step SA61 shown in FIG. Shift to the process when the training is stopped.
[0043]
b. When accompaniment playback timing is reached
When the accompaniment time T2 decremented every time the minimum time elapses becomes “0” and the accompaniment reproduction timing is reached, the determination result in step SA40 shown in FIG. 13 becomes “YES”, and the process proceeds to step SA41, where the accompaniment pattern address pointer Increment and advance. Next, in step SA42, data is read from the accompaniment pattern according to the accompaniment pattern address pointer that has been advanced. In step SA43 and subsequent steps, processing corresponding to the read data type is executed. Hereinafter, processing in each case where the data type read from the accompaniment pattern is “time T”, “event ET”, and “data END” will be described.
[0044]
<In case of time T>
If the data read from the accompaniment pattern is time T, the determination result in step SA45 is “YES”, the process proceeds to step SA46, the time T is stored in the register T2, and the accompaniment time T2 is updated. The process proceeds to step SA51.
[0045]
<In case of event ET>
If the data read from the accompaniment pattern is the event ET, the process proceeds to step SA47 shown in FIG. In step SA47, it is determined whether or not the event ET is an event including pitch data. If the event does not include pitch data, the determination result is “NO”, the process proceeds to step SA49, and the event is sent to the sound source 35 as it is. Thereby, a normal accompaniment sound is reproduced.
On the other hand, if the event includes pitch data, the determination result in step SA47 is “YES”, and the flow proceeds to step SA48. In step SA48, the pitch data included in the event is pitch-converted according to the code data stored in the register CODE. Next, the process proceeds to step SA49, and an event including the pitch data whose pitch has been converted is sent to the sound source 35. Thereby, the chord accompaniment sound is reproduced. In step SA50, the accompaniment pattern address pointer is incremented and stepped, and then the process returns to step SA42 in FIG. 13 to read the next data from the accompaniment pattern.
[0046]
<For data END>
If the data read from the accompaniment pattern is data END indicating the end of the pattern, the determination result in step SA43 shown in FIG. 13 is “YES”, and the flow proceeds to step SA44. In step SA44, the accompaniment pattern address pointer is reset and returned to the head address. Thereafter, the process returns to step SA42, and the accompaniment pattern is read again from the head. Therefore, during a dance lesson, an accompaniment pattern for a predetermined measure is repeatedly reproduced to generate an accompaniment sound.
[0047]
c. When the image update timing is reached
When the step time T3 that is decremented every time the minimum time elapses becomes “0” and the image update timing is reached, the determination result in step SA51 shown in FIG. 14 becomes “YES”, and the process proceeds to step SA52, where the step address pointer is set. Increment and advance. Next, in step SA53, step data SD is read in accordance with the step address pointer that has been advanced. In step SA54 and subsequent steps, processing corresponding to the data type read from the step data SD is executed. Hereinafter, processing in each case where the data type read from the step data SD is “time T”, “step event ST”, and “data END” will be described.
[0048]
<In case of time T>
If the data read from the step data SD is time T, the determination result in step SA56 shown in FIG. 15 is “YES”, the process proceeds to step SA57, the time T is stored in the register T3, and the step time T3 is updated. After that, the process returns to step SA1 in FIG.
If neither the start switch nor the stop switch is turned on, the determination results in steps SA1 and SA2 in FIG. 9 are both “NO”, and the process returns to step SA25 in FIG.
[0049]
<In case of step event ST>
If the data read from the step data SD is the step event ST, the determination result in step SA58 is “YES”, and the flow proceeds to step SA59. In step SA59, the corresponding pose image data is read from the pose image group PI (see FIG. 5) in the RAM 33 in accordance with the pose image identification data ED1 included in the step event ST, and displayed on the display unit 34. Subsequently, in step SA60, a step graphic image representing the foot movement of each man and woman according to the male right foot position data ED2, the male left foot position data ED3, the female right foot position data ED4 and the female left foot position data ED5 included in the step event ST. After executing a step graphic image change process (described later) for changing data, the process returns to step SA1 in FIG. Thereafter, if neither the start switch nor the stop switch is turned on, the determination results in steps SA1 and SA2 in FIG. 9 are both “NO”, and the process returns to step SA25 in FIG.

<For data END>
If the data read from step data SD is data END indicating the end of the step, the determination result in step SA54 shown in FIG. 14 is “YES”, and the flow proceeds to step SA55. In step SA55, the pose image and step graphic image displayed on the display unit 34 are erased, and then the process returns to step SA1 in FIG. Thereafter, if the start switch and stop switch are not turned on, the determination results in steps SA1 and SA2 in FIG. 9 are both “NO”, and the process returns to step SA25 in FIG.
[0051]
(3) Operation when dance lesson is stopped
When the user turns on the stop switch to stop the dance lesson, the determination result in step SA2 shown in FIG. 9 is “YES”, the process proceeds to step SA61, and the start flag STF is reset to zero to indicate the lesson. Subsequently, in step SA62, the sound source 35 is instructed to mute all the musical sounds that are being generated. In step SA63, the pose image and step graphic image displayed on the display unit 34 are erased to complete the present process.
[0052]
(3) Step image change processing operation
Next, the operation of the step image change process will be described with reference to FIG. When the step image change process is executed via step SA60 (see FIG. 15) of the dance process described above, the CPU 31 proceeds to step SB1 shown in FIG. 16, and the male right foot position data ED2 and the male left foot included in the step event ST. Position data ED3, female right foot position data ED4, and female left foot position data ED5 are acquired. Next, in step SB2 and subsequent steps, it is determined whether or not there is a change in foot position from the difference between the male and female foot positions defined in the previous step event ST. If there is no change, the step graphic image is not changed and there is a change. The display position of the step graphic image data is changed in accordance with the change, and the locus corresponding to the change is displayed.
[0053]
That is, if there is a change in the male right foot position, the determination result in step SB2 is “YES”, the process proceeds to step SB3, and the display position of the step graphic image data representing the male right foot side is changed according to the change. If there is a change in the male left foot position, the determination result in step SB4 is “YES”, and the process proceeds to step SB5, where the display position of the step graphic image data representing the male left foot side is changed.
Furthermore, if there is a change in the position of the female right foot, the determination result in step SB6 is “YES”, the process proceeds to step SB7, and the display position of the step graphic image data representing the female right foot side is changed according to the change. If there is a change in the position of the female left foot, the determination result in step SB8 is “YES”, the process proceeds to step SB9, and the display position of the step graphic image data representing the female left foot side is changed according to the change. In step SB10, the trajectory is displayed with an arrow corresponding to the change of the display position in steps SB3, SB5, SB7 and SB9, for example, as shown in FIG.

As described above, in the present embodiment, the accompaniment pattern group PDG, the pose image group PI for displaying the model posture for each dance step on the screen in advance and the step graphic image for displaying the footsteps of both men and women on the terminal 3 side in advance. When SI is stored and the terminal 3 downloads the music data MD and the step data SD from the server 1 and performs a dance lesson, the terminal 3 displays the accompaniment pattern corresponding to the pattern number included in the music data MD. During the step data SD selected from the group PDG, the accompaniment sound by the selected accompaniment pattern and the performance sound by the SMF included in the music data MD are reproduced, and the pause image and the step graphic image are displayed in synchronization with the music reproduction. The pose image specified by the step event and the step corresponding to this pose image Since the screen displays a graphic image, it becomes possible to provide dance training service without performing a download of the huge amount of data.
[0055]
In the above-described embodiment, the music data MD and the step data SD are downloaded from the server 1 to the terminal 3. However, the present invention is not limited to this. For example, dance lesson content (accompaniment) previously compressed and encrypted on the terminal 3 side. Pattern, SMF, pose image and step graphic image), and the terminal 3 downloads the decryption key from the server 1, and decompresses and decrypts the desired dance lesson content with the decryption key to perform the dance lesson. I do not care. In this way, the amount of data to be downloaded can be further reduced.
[0056]
Further, in the present embodiment, the music data MD and the step data SD are downloaded from the server 1 to the terminal 3, but instead of this, step data for displaying a pause image and a step graphic image in synchronization with the music reproduction. Only SD may be downloaded from the server 1 to the terminal 3. In this case, the music to be played is selected by the user's operation on the terminal 3 side.
Further, in the present embodiment, an example of providing a social dance learning service has been mentioned. However, the gist of the present invention is not limited thereto, and for example, an aerobics training that displays a body movement in synchronization with the reproduction of dance music is displayed. It can also be applied to golf lessons in which the lesson content is played back in audio and the address, grip, posture, and movement during swing are displayed as images.
