Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reservation information display device for displaying a reservation status of a song desired to be performed.

[Prior Art] Conventionally, for example, some karaoke apparatuses have a function of reserving some songs and automatically playing the reserved songs one after another in the order of the reservation.

[Problems to be Solved by the Invention] For karaoke users, if there are many people making reservations, or who knows that it is their turn to sing next, but who is currently singing? If you've booked a song, you'll be very concerned about how many minutes later the song you plan to sing will be played. You have to be prepared to stand and receive the microphone, and more than that.

However, the conventional karaoke apparatus does not have a function for informing what time the scheduled time at which each reserved song should be played is.

Usually, the reservation is made by a person at the store, but by asking the person who made the reservation (reservation operator) how many songs have been played, it is possible to know the order of yourself, but still, how many more songs I knew only how many minutes later the performance would begin, based on the number of songs waiting and the approximate time per song. Also, asking the reservation operator one by one was psychologically troublesome.

In fact, when the song of the person who is currently singing has finished playing and the next song has started playing, it is the song that you have reserved for the first time, knowing if the song is your reserved song After knowing that, he moves on to stand and take a microphone. However, that would make you feel very busy and you wouldn't be able to fully enjoy karaoke.

[Object of the Invention] The present invention has been made to solve the above-described problems, and has as its object to be able to notify a user of scheduled performance times of individual reserved songs.

[Means for Solving the Problems] To achieve this objective, reservation information display device of the present invention, as illustrated in Figure 1, the designation information A _i for specifying the song you want to play An input means Mi for inputting; a reservation data storage means M3 for storing reservation data D1 consisting of a song title _mi and a required playing time t _{i of} a song designated for each piece of the designation information A _i in the order of input; Timing means M2
Based on the time t read from the timer M2 and the required playing time t _i read from the reservation data storage M3, the scheduled playing time T _i of each reserved song is determined in the order of input, and the song title m _i
Wherein a control means M4 for outputting the scheduled play time T _i, and display means M5 for displaying Song m _i and scheduled playing time T _i output of the control means M4 with.

[Operation] reservation information display device of the present invention having the above configuration inputs the specification information A _i of the plurality of reserved song from the input unit M1,
The reservation data storage unit M3 stores reservation data D1 in which the designation information _Ai , the song title _mi, and the required playing time t _i are associated with each other. The control means M4 reads the reservation data D1 from the reservation data storage means M3, and the timer means M2 reads the time t, and the time t and the required playing time of each reserved music in the reservation data D1.
The scheduled performance time T _i of each reserved song is calculated from t _i . And
After transmitting the data of the Song m _i and scheduled playing time T _i of each reservation songs on the display unit M5, and Song scheduled play time of each reservation songs are displayed.

Therefore, the person who has made a reservation for the desired music piece can know the scheduled time at which his or her reserved music piece is to be played by looking at the displayed music piece name and the expected performance time.

₂ is mixed with the performance audio signal S ₁ in the mixing amplifier 10, and is output as sound from the speaker 12.

Next, the operation of displaying the song titles and scheduled performance times of the reserved songs on the CRT monitor 17 in the order of reservation will be described with reference to the flowchart of FIG.

As a premise of this operation description, it is assumed that reservation data D1 _i (i, A _i , _mi , t _i ) (i = 1, 2 ‥‥ n) of a plurality of reserved music pieces have already been stored in the RAM 3.

The CPU 1 waits for the performance key on the operation panel 7 to be pressed in step S1, and proceeds to step S2.
Search for RAM3 and total number n of reserved songs stored in RAM3
The store to register R _1. Variable j is set to “1” in step S3
And the variable i is set to "j + 1" in step S4.

The variable j is the reservation order number of the tune to be played this time, and the variable i is the reservation order number of the tune to be played immediately after. This is because the title and scheduled performance time of the song to be played this time are not displayed on the CRT monitor 17, but the title and scheduled performance time of the reserved songs following the one to be played after are displayed. This is to make it correspond.

In step S5, based on the variable j reads out the music number A _j to be played this time from the RAM 3. The first time, the reservation order is read first song number A _1. In step S6, the timer 19 is started.

In step S7, a performance process of the music corresponding to the current music number _Aj is executed. That is, the music number A _j then searches the storage device 4 reads the performance data D2 _j and lyrics data D3 _j corresponding to the music number A _j based on the tone performance data D2 _j via the interface 8 combining unit 9 And the lyrics data D3 _j is sent to the character generator 15, and at the same time, the playback device 14 is driven to read the background video data D4 from the laser disk 13. Thus, the performance output from the speaker 12 is performed, and the lyrics and the background image are displayed on the CRT monitor 17.

In the next step S8, the count time t is read from the timer 19, and in step S9, the song numbers A _i , A _{i + 1} ‥‥ A of all reserved songs to be played in the future except the song currently played from the RAM 3
_{i + n-2} (the first time i = 2, so the required playing time t _i , t _{i + 1} ‥‥ t _{i + n-2} (A ₂ , A ₃ ‥‥ A _n ) (the first time is t ₂ , t ₃ ‥‥ t _n )
And the scheduled performance time T _i , T _{i + 1} ‥‥ T _{i + n-2 of the} song numbers A _i , A _{i + 1} ‥‥ A _{i + n-2} excluding the music currently being played in step S10
Is calculated by calculation.

The formula is It is.

The first song when the (j = 1) has been played, the second song (i = j + 1 = 2 ) and later of the song number A _2, A ₃ ‥‥ A scheduled playing time T ₂ of each reservation songs _n, T ₃ ‥‥ T _n is, as shown in the upper half of FIG. become that way.

Data (m _i , T _i ), (m _{i + 1} , T _{i + 1} ) of the music title and scheduled performance time of each reserved music to be played in step S11
By transmitting (m _{i + n-2} , T _{i + n-2} ) to the character generator 15, the CRT monitor 17 displays the titles of the reserved songs to be played in the future and the respective scheduled performance times.

In this way, the karaoke user waiting for the singing order can be notified of the scheduled performance time of the reserved song, and those who are going to sing the song to be played next to the currently played song,
I will prepare.

Step S12 determines whether the song end code which is located at the end of the performance data D2 _j is read in, until it is read out repeating the steps S7 to S12.

In the process of this repetition, the count time t by the timer 19 changes every moment, and accordingly, the scheduled performance times T _i , T
_{i + 1} ‥‥ T _{i + n-2} also decreases every moment. And that is C
It is displayed on the RT monitor 17 while changing in real time.

When the song end code is read, the performance of the currently played song ends.However, the process proceeds to step S13, where the timer 19 is reset. Reservation data D1 corresponding to j
_j (j, A _j , m _j , t _j ) is deleted.

Next, in step S15, the song number A of the song that has just been played
Song name m _{i associated} with song number A _i that has one reserved ranking after _j
And by stopping the transfer of data scheduled playing time T _i, CRT monitor 1 to display the title and scheduled play time
At the same time as deleting from the screen of 7, the subsequent song numbers A _{i + 1} ‥‥ A
The title and scheduled performance time of the reserved song related to _{i + n-2} (m _{i + 1} , T
_{i + 1} ) ‥‥ (mi _{+ n-2} , _{Ti + n-2} ) is scrolled upward on the screen of the CRT monitor 17.

Then, the process proceeds to step S16, where the variable i is incremented by +1.
Is determined, and if not, the process returns to step S4, and thereafter, steps S4 to S17 are repeated.

The second song (j = 2) When is playing, the third song (i = j + 1 = 3 ) scheduled playing time T ₃ ‥‥ T _n of each reservation song after song number A ₃ ‥‥ A _n is, Arithmetic expression, , As shown in the lower half of FIG. become that way.

When the variable j is determined in step S17 has reached a reserved music number n, after clearing the register R ₁ and variable j which stores the reservation number of tracks n proceeds to step S18, the whole process is terminated .

FIG. 5 shows a display example of the CRT monitor 17. It is assumed that the number of reserved songs n is, for example, four.

During the performance of the song whose reservation order number is 1st, FIG.
At the top of the screen, the titles of the second to fourth reserved order numbers and the scheduled performance times (m ₂ , T ₂ ), (m ₃ , T ₃ )
(M ₄ , T ₄ ) is displayed. The lyrics of the first song being played are displayed at the bottom of the screen, and a background image is displayed on the entire screen. The scheduled performance times T _{1 to} T ₄
As already mentioned, it changes (decreases) in real time.

With the end of the performance of the first tune, the display of the name of the second tune and the scheduled performance time (m ₂ , T ₂ ) disappears, and with the start of the performance of the second tune, as shown in FIG. The third and fourth music titles and the scheduled performance times (m ₃ , T ₃ ) and (m ₄ , T ₄ ) are scrolled upward by one line and displayed.

With the end of the performance of the second tune, the display of the title of the third tune and the scheduled performance time (m ₃ , T ₃ ) disappears, and with the start of the performance of the third tune, as shown in FIG. The title and the scheduled performance time (m ₄ , T ₄ ) are scrolled upward by one line and displayed.

Then, the display of the Song Title m ₄ and will play time T ₄ is erased along with the performance end of the third song. When the fourth tune, which is the last tune to be reserved, is being played, the tune name and the scheduled performance time are not displayed on the CRT monitor 17 as shown in FIG. 5 (d).

In the above-described embodiment, the title of the reserved song to be played in the future and the scheduled playing time are always displayed. However, the display may be performed only when a display command is issued from the operation panel 7. .

Note that, as items to be displayed on the CRT monitor 17 for songs to be played in the future, a singer name, a genre, a lyricist name, a composer name, and the like may be displayed together with the song name.

In the above embodiment, the background video read from the video disk 13 is configured to be displayed on the CRT monitor 17, but this configuration may be omitted. In that case, the video disk 13, the reproducing device 14, and the video synthesizing circuit 16 become unnecessary.
In the above embodiment, the storage device 4 stores the lyrics data D3.
And the lyrics are displayed on the CRT monitor 17, but this configuration is not essential. In this case, the CRT monitor 17 is dedicated to displaying not only the operation guide and the operation result from the operation panel 7 but also the title of the song to be played and the scheduled performance time.

Further, the designation information may be any information as long as it can specify not only the music number but also each music.

Further, the present invention can be applied to a music performance device other than the karaoke device that plays music according to a reserved music order.

[Effects of the Invention] As is apparent from the above description, according to the present invention, the scheduled performance time of each reserved song is determined from the required playing time and time of each reserved song, and the title and the title of each reserved song are determined. Since the scheduled performance time is displayed, the user can be notified of the scheduled performance time of each reserved song. Therefore, there is an effect that the user can know at a glance the scheduled time at which his / her reserved song is to be played by looking at the displayed song name and the scheduled performance time.
