[Action]
In this invention, a studio apparatus is installed in a studio where a performer is waiting, and a box apparatus or a karaoke apparatus is installed in a karaoke box where a singer sings. Songs and genres that can be played by the performer are transmitted from the studio to the karaoke box, and an inquiry for a song request is transmitted from the karaoke box to the studio. As a result, a performer who can play the song is played by the customer, and the performance sound is distributed remotely.

  According to the present invention, a performer and a karaoke singer can be remotely connected, and the singer can select a performer who can respond to his request and request performance. Even if there are no performers, live performances that meet the needs of the singer can be provided.

A live performance karaoke system as an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a functional block diagram of this live performance karaoke system.
In a large-scale karaoke store, this system has a studio where players such as live bands stand by in addition to a private room (karaoke box) where karaoke equipment is installed. This is a system in which a live band plays live. Requests, live performance audio / video, and the like are transmitted between the studio apparatus and the karaoke apparatus via the network 13.

  In FIG. 1, the studio has a performance sound collection unit 9 that collects the performance sound of the live performance 1, a player shooting unit 6 that captures the performance of the performer, and a beat that detects the beat timing of the live performance. A detection unit 2 is provided. The beat detection unit 2 may employ, for example, a component that detects beats based on the envelope of the musical tone of a rhythm instrument such as a drum. The beat pulse generation unit 3 generates a pulse signal synchronized with the beat timing detected by the beat detection unit 2 (this pulse signal is transmitted as a packet in the network). In addition, when a live performance is performed supplementarily using an electronic device such as a rhythm machine, the signal of the rhythm machine may be used as it is as a beat pulse.

  The performance sound picked up by the performance sound pickup unit 9, the player video shot by the player shooting unit 6, and the beat pulse generated by the beat pulse generation unit 3 are sent to the karaoke box via the network 13.

  The karaoke box has a sequence clock generation unit 4, a lyrics sequence unit 5, a video composition unit 7, a display unit 8, a sound mixing unit 10, a sound emitting unit 11, and a singing microphone 12. The audio mixing unit 10 mixes the received performance sound with a singing audio signal input from the microphone 12. The sound emitting unit 11 amplifies the mixed audio signal and emits the sound from the speaker.

  The sequence clock generator 4 detects the performance tempo based on the received pulse interval and generates a sequence clock. The lyric sequence unit 5 uses the lyric track included in the song data of karaoke and generates a lyric telop at a tempo based on the sequence clock. The synthesizing unit 7 superimposes the lyrics telop on the player video sent from the studio. The synthesizing unit 7 may synthesize a background video reproduced by the karaoke apparatus as a background of the synthesized video. The display unit 8 displays this synthesized video.

  In this way, even in a live performance, the beat timing of the performance is detected and the lyrics telop is sequenced and displayed, so the singer in the karaoke box looks at the lyrics as in the case of normal karaoke music I can sing.

  FIG. 2 is a diagram showing a system configuration of the live performance karaoke system. This figure assumes a large-scale karaoke store. A number of private rooms (karaoke boxes) in which the karaoke apparatus 20 is installed are provided (seven in the figure), and a plurality of studios (three in the figure) in which live performers are waiting are provided. . Each studio is equipped with a sound collection unit that picks up the performance sound of a live performance, a photographing unit that captures the appearance of the performer, a beat detection unit that detects beat timing based on the live performance sound, a beat pulse generation unit, etc. A studio device 21 is installed. Each karaoke apparatus 20 and each studio apparatus 21 are connected by a network 23. This network 23 is configured by an indoor LAN.

A server device 22 is also connected to the network 23. The server device 22 is a device that records (records) live performance data transmitted from the studio device 21 to the karaoke device 20. By recording live performance data, it is possible to provide a past live performance as an alternative even if the live performance cannot be provided to the user of the karaoke box. When providing live performance as a paid service, the recorded live recording data can be provided as a less expensive service or a free service than live performance.
In the case where a plurality of studios are installed as shown in FIG. 2, it is desirable to have different types of performers such as rock bands, acoustic guitar solos, piano solos, string quartets, etc. stand by in each studio.

  FIG. 2 shows an example in which a karaoke box and a studio are installed in the same store and are connected by an indoor LAN. However, the karaoke device 20 and the studio device are provided in a remote place different from the karaoke box. 21 may be connected to the Internet.

  FIG. 3 is a block diagram of the karaoke apparatus 20 installed in each karaoke box. The karaoke apparatus 20 can play a karaoke song based on the music data stored in the hard disk 111 and can also reproduce the performance sound and the player video sent from the studio apparatus 21.

  The karaoke apparatus 20 includes a CPU 110 that controls the operation of the entire apparatus and various devices connected to the CPU 110. Connected to the CPU 110 are a hard disk 111, RAM 112, sound source 113, mixer (effector) 114, MPEG decoder 120, synthesis circuit 121, operation unit 123, LAN interface 124, infrared communication unit 125, and the like.

  The hard disk 111 stores music data 140 for playing karaoke music, video data 141 for display as a background video on the monitor 122, and the like. Video data stores both moving images and still images. In the RAM 112, a reservation table shown in FIG.

  CPU 110 executes processing such as sequencer 130, background video reproduction processing 133, network communication control processing 134, and operation input processing based on a program stored in hard disk 111. The sequencer 130 includes a song sequencer 131 and a lyrics sequencer 132.

  The song sequencer 131 is a program for executing a karaoke song based on song data stored in the HDD 111. The music data has a structure as shown in FIG. The song sequencer 131 controls the sound source 113 based on the data of the musical tone track and the guide melody track, and generates the musical tone of the karaoke song. The lyrics sequencer 132 is a program for displaying the lyrics telop on the monitor 122 based on the song data of the karaoke song. The lyrics sequencer 132 synthesizes the character pattern of the lyrics in synchronism with the progress of the song based on the lyrics track (see FIG. 5) included in the song data shown in FIG. 4, and converts the character pattern into a video signal for synthesis. Input to the circuit 121.

  The sound source 113 forms a musical sound signal according to data (note sound data of a musical tone track or a guide melody track) input from the CPU 110 by processing of the music sequencer 131. The formed tone signal is input to the mixer 114. The mixer 114 gives an effect such as echo to the plurality of musical sound signals generated by the sound source 113 and the singing voice signal of the singer input via the microphone 117-A / D converter 118. Mix the signal with an appropriate balance. The mixed digital audio data is input to the sound system 115. The sound system 115 includes a D / A converter and a power amplifier, converts input digital audio data into an analog signal, amplifies it, and emits sound from the speaker 116. The effect that the mixer 114 gives to each audio signal and the balance of mixing are controlled by the CPU 110.

  The background video playback processing 133 reads the video data 141 stored in the HDD 111 and plays back the background video in synchronization with the generation of musical sounds and the generation of lyrics telop by the sequencer 130. The video data of the moving image is encoded in the MPEG2 format. The background video reproduction process 133 inputs the read video data of the moving image to the MPEG decoder 120. The MPEG decoder 120 converts the input MPEG data into an NTSC video signal and inputs it to the synthesis circuit 121. In addition to the video signal of the background video, the lyrics telop character pattern and the like are input to the synthesis circuit 121. The synthesizing circuit 121 synthesizes an OSD such as a lyrics telop on the video signal of the background video and outputs it to the monitor display 122. The monitor display 122 displays the video signal input from the synthesis circuit 121.

The operation unit 123 has various key switches provided on the operation panel surface and a panel switch interface for detecting operations of the key switches. The various key switches include a numeric keypad for inputting a song number for specifying a karaoke song.
The infrared communication unit 125 is a communication unit that receives various command signals transmitted from an infrared remote control device (not shown). A song number or the like is sent from the infrared remote control device.

  The LAN interface 124 is an interface for communicating with the studio apparatus 21 and the server apparatus 22 via the network (LAN) 23 (see FIG. 2). Communication via the LAN interface 124 is controlled by the network communication control unit 134 of the CPU 110. The LAN interface 124 receives the performance sound signal, the player video, and the beat pulse sent from the studio apparatus 21 and passes them to the network communication control unit 134. The network communication control unit 134 reproduces audio stream data, video stream data, and beat pulses from the received packet, outputs the audio stream data to the mixer 114, and outputs the video stream data to the MPEG decoder 120. In addition, a beat pulse is input to the sequencer 130.

  When reproducing the live performance of the studio, the MPEG decoder 120 decodes the player video data sent from the studio device 21 via the network 23, and the synthesis circuit 121 outputs the lyrics on the decoded player video. Superimpose the telop. In addition, by making the wall surface of the studio blue, the player's video can be a blue background. The video data 141 may be reproduced by the karaoke apparatus 20 as a background video, and a blue-back player video and lyrics telop may be synthesized thereon. In this case, the MPEG decoder 120 can decode both the background video (video data 141) and the player video data in parallel, and the synthesis circuit 121 simultaneously outputs the three videos of the background video, the player video, and the lyrics telop. It can be synthesized.

  The sequencer 130 generates a sequence clock based on the input beat pulse interval. The sequence clock is a clock signal obtained by dividing one beat into 32 parts. Then, the music data is sequenced based on the sequence clock. When playing a live performance, it is only necessary to operate the lyrics sequencer 132 that generates the lyrics telop using the lyrics track in the song data. However, if necessary, the song sequencer 131 is operated to reproduce the guide melody track. You may do it.

  The mixer 114 mixes the live performance audio stream data and the singing audio signal input from the microphone 117 and outputs the result to the sound system 115. When the music sequencer 131 reproduces the guide melody track, the guide melody sound input from the sound source 113 is also mixed and output.

4 and 5 are diagrams showing the composition of music data stored in the hard disk 11. As shown in FIG.
In FIG. 4, the music data includes a header, a music track for playing karaoke music, a guide melody track for generating a guide melody, and a lyrics track for displaying a lyrics telop, as shown in FIG. It consists of such.

Each track is described according to the MIDI format. For example, a musical tone track and a guide melody track are composed of event data such as note-on event data and note-off event data and timing data indicating the read timing of each event data, as shown in FIG. The note-on event data includes pitch data, and designates the pitch and volume of a musical sound generated by the note-on. This musical sound continues until the corresponding note-off event data is read out.
The timing data can be composed of duration data indicating the time interval between the event data, absolute time data indicating the absolute time from the start time of the music, and the like.

  The event data of the musical tone track and the guide melody track is composed of the note event data indicating the pitch, volume, on / off, etc. of the musical tone as described above, and by inputting this note event data to the sound source 113, the sound source A sound 113 corresponding to the event data is generated or muted. The musical sound track is composed of a plurality of tracks (parts) for generating musical sounds of a large number of musical instruments, and the guide melody track is composed of single melody MIDI data for guiding the singing melody.

  The lyric track is sequence data that implements various data for displaying the song title and lyrics of the karaoke song. As shown in FIG. 5 (A), the lyric track is based on page break data and lyric display data read based on the timing data. It is configured.

  The page break data is data that separates the lyrics displayed on the monitor 122 on a line-by-line basis (2-4 lines) at the same time, and corresponds to musical phrases of karaoke songs. The lyric display data includes all data related to lyric display for one line, display on timing, display off timing, character string data (including the number of display points, display coordinates, character spacing data, etc.), color 1 data , Color 2 data, wipe data, and the like.

  The display mode of the lyrics is as follows. First, the lyrics for one line are displayed in color 1, and for a while (until the song progresses to the location of the lyrics), it is stopped in the same color (ton). The display color is wiped in accordance with and the color is changed from color 1 to color 2 in order from the left. Finally, it is displayed after being displayed in color 2 for a while (te) and then erased.

  The wipe data is composed of a plurality of plotting data indicating the main points of the (time-x coordinate) curve of the wipe as shown in FIG. The lyrics sequencer 132 performs color change (wipe) by interpolating the plotting data with a quadratic curve.

  In the case of performance of normal karaoke music, the color is changed in accordance with the progress of the music in this way. However, when the live performance sent from the studio apparatus 21 is reproduced, one line or two lines are sequentially played. It is possible to change the color only by displaying the lyrics.

  The operation of the karaoke apparatus 20 will be described with reference to FIGS. FIG. 6 is a flowchart showing a reservation acceptance operation of the karaoke apparatus. FIG. 7 is a diagram showing a reservation table set in the RAM 112. FIG. 8 is a diagram showing a display example of the monitor 122 when a live performance is reserved for the studio apparatus 21.

  In FIG. 6, when a song number is input from the user (S1), this song number is registered at the end of the reservation table of FIG. 7 (S2). Then, the predicted performance start time (waiting time) of the currently reserved karaoke song is calculated by summing up the expected performance times of the karaoke songs that are reserved in advance and played before the currently reserved song (S3). ). Then, the song number and the waiting time are transmitted to the studio apparatus 21 to inquire whether or not this song can be played live (S4).

In the studio apparatus 21, the performer determines the song name from the song number and determines whether the song is a repertoire. Also, based on the expected performance start time, it is confirmed whether another performance reservation has been received at that time. If the performance is possible, the performer operates the studio apparatus 21 and replies that the performance is possible. Even if the performance is impossible, the performer operates the studio apparatus 21 and replies that the performance is impossible.
When a reply indicating that the karaoke apparatus can be played is received (YES in S5), a screen as shown in FIG. 8 is displayed and a reservation for live performance is accepted (S6).

  Here, the live performance reservation acceptance screen will be described with reference to FIG. FIG. 6A shows the first screen displayed on the monitor 122. This screen is a screen that is displayed when a reply indicating that the studio apparatus 21 can perform is returned. The screen includes an indication that a live performance is possible and the name of the performer. When replies indicating that performance is possible are received from a plurality of performers (studio apparatus 21), the names of all performers are displayed.

  The display portions of “Performer A” and “Performer B”, which are performer names, are buttons 51A and 51B. When these buttons are turned on by a cursor operation of a remote control device or the like, the screen shown in FIG. Transition. If the user does not select a live performance and the "don't need" button 52 is turned on, the process proceeds to S9 with a NO determination in S7 of FIG.

  On the screen shown in FIG. 5B, a live performance fee, etc., such as the profile and photo of the selected player, are displayed. On this screen, a “request” button 53, a “call” button 54, and a “return” button 55 are displayed. When a user requests this performer to perform a live performance, a “request” button 53 is clicked. If it does so, operation | movement will progress to S8 by determination of YES of S7 of FIG. 6, the live performance flag of this music of a reservation table will be set, and reservation operation will be complete | finished.

  When the “call” button 54 is turned on, a call can be made with the studio apparatus 21. In the call state, as shown in FIG. 8C, the video of the player photographing unit 6 of the studio apparatus 21 is displayed at the top of the screen, and conversation can be performed with each other's microphone (the video of the karaoke box is the studio Is not transmitted to). Here, the user of the karaoke apparatus 20 can refer to the judgment as to whether or not to request a live performance by asking questions about what version of the performance can be performed by a studio player. The user turns on the “request” button 53 when requesting a live performance. When not making a request, the “return” button 55 is turned on.

  When the “return” button 55 is turned on in the screens of FIGS. 8B and 8C, the display on the monitor 122 shifts to the screen of FIG. When the user returns to the screen shown in FIG. 5A, the user may select another player and make a request, or turn on the “don't care” button 52 to make a request for a live performance. it can.

  If there is no reply that the live performance is possible from the studio (NO in S5), or if the user does not request a live performance (NO in S7), the process proceeds to S9. In S9, it is searched whether the past live performance recordings (audio and video) are recorded in the server device 22. If there is a recording, the operation proceeds to S11 and subsequent steps with a YES determination in S10. The operation after S11 is almost the same as the live performance reservation operation after S6.

  Here, the recording performance reservation reception screen will be described with reference to FIG. FIG. 6A shows the first screen displayed on the monitor 122. This screen is displayed when a reply is received from the server device 22 that there is a recording of a reserved song. The screen includes the presence of the recording and the name of the performer of the recording. When there are recordings of a plurality of performers, all performer names are displayed.

  The display portions of “Performers A” and “Performers B”, which are the names of performers, are buttons 61A and 61B. When these buttons are turned on by a cursor operation of a remote control device or the like, the screen shown in FIG. Transition. If the user does not select the recording performance, the “don't care” button 62 is turned on, and the reservation process is terminated with a NO determination in S12 of FIG.

  On the screen shown in FIG. 5B, a live performance fee, etc., such as the profile and photo of the selected player, are displayed. On this screen, a “request” button 63 and a “return” button 65 are displayed. When the user reserves the performance of this recording, the “request” button 63 is clicked. If it does so, operation | movement will progress to S13 by YES determination of S12 of FIG. 6, the recording flag of this music of a reservation table will be set, and reservation operation will be complete | finished. If the user does not reserve the recording performance, the “return” button 65 is turned on.

  When the “return” button 65 is turned on in the screen of FIG. 9B, the display of the monitor 122 shifts to the screen of FIG. When the user returns to the screen shown in FIG. 5A, the user selects and requests a recording by another player, or turns on the “don't care” button 62 to perform an operation to request no recording performance. be able to.

  If there is no recording in server device 22 (NO in S10), or if the user does not request a recording performance (NO in S12), the reservation process is terminated. When neither live performance nor recording performance is selected, a normal karaoke performance based on music data is performed.

  In the above reservation process, the customer first selects a karaoke song and selects a karaoke song, and if the player can play the karaoke song live, the live performance is requested. It is also possible to adopt a reservation method in which a player is designated and a song that can be played by the performer is requested.

FIG. 10 is a flowchart showing a reservation method procedure for selecting a performer first. FIG. 11 is a diagram showing an example of the display screen of the monitor 122 at that time.
This reservation method and the reservation method of FIG. 6 can be reserved by either method with the same karaoke apparatus by mode switching. Then, the reserved karaoke (live performance) tunes are registered in the same reservation table and played in the registered order.

  10, in this reservation method, first, the genre selection screen shown in FIG. 11A is displayed (S50). This genre selection screen narrows down performers according to the genre of music. On this screen, each genre name is a button, and by turning on any genre name button, that genre is selected. In addition to selecting the genre or instead of selecting the genre, the performers may be narrowed down by the performer's performance form (band, guitar solo, piano solo, etc.).

  When the user of the karaoke box selects a desired genre, a list of performers performing songs of that genre is displayed (S51). This list is as shown in FIG. 11B, and each player name is a button.

  When the user selects a desired player from the displayed performers, the display on the monitor 122 shifts to the introduction screen for the performer (S52). This player introduction screen is, for example, a screen as shown in FIG. Here, when the user wants to request a live performance of the performer, the user turns on the “select music” button. Then, the operation proceeds to the request processing in S57 based on the determination in S53.

  When the “return” button in the screen is turned on, the screen display state is returned to the previous screen unless otherwise described.

  In S57, in response to the determination that the “select music” button is turned on in S53, a list of songs that the performer can perform is displayed (S57). Here, a button input is accepted (S57), and when the button of any song is turned on (selecting a song in S58), a request confirmation screen for that song is displayed (S60: FIG. 11 (F)). If the "Yes" button is turned on, the process proceeds to S62 with a determination of S61 (Yes), and this song is registered in the reservation table (S62), and the operation is terminated. On the other hand, when the “No” button is turned on in the screen of FIG. 11F, the process returns to S57 (FIG. 11E) in order to redo the music selection.

  If the “Return” button is turned on in the display screen of the music list that can be played (FIG. 11E), it is determined that the player does not intend to request the music, and the determination in S58 is made. The player selection screen (S51: FIG. 11B) is returned to.

  In addition, when the user wants to know more about the performer while the performer introduction screen is displayed in S52, the “profile” button is turned on. If it does so, operation will progress to S54 by judgment of S53. In S54, a profile introduction screen as shown in FIG. 11D is displayed. If the user wants to talk to the performer on this screen, the "call" button is turned on. In S55, the operation proceeds to S56, and the studio apparatus 21 and the karaoke apparatus 20 communicate via the network to communicate with the performer. (S56). At this time, the player's video is displayed on the right side of the profile introduction screen as shown in FIG. When the “return” button is turned on in the profile introduction screen, the player introduction screen (S52) is returned.

  FIG. 12 is a flowchart showing a performance process of the karaoke apparatus 20. First, the music number registered at the head of the reservation table is read (S20). At this time, the read music number is deleted from the reservation table, and the next registered music number is shifted upward. Then, it is determined whether the live performance flag or the recording flag of the read music number is set (S21, S25). If the live performance flag is set (YES in S21), the corresponding studio is instructed to start performance (S22). Then, after receiving the beat pulse (S23), the lyrics sequence is started (S24).

If the recording flag is set (YES in S25), the server device 22 is instructed to start streaming distribution of the recorded performance (S26). Then, after receiving the streaming beat pulse (S23), the lyrics sequence is started (S24).
If neither the live performance flag nor the recording flag is set (NO in S21 and S25), a normal karaoke performance based on music data is executed (S27).

  FIG. 13 is a flowchart showing the procedure of the lyrics sequence. FIG. 3A is a flowchart showing sequence clock generation processing. The tempo of the music is detected based on the pulse interval of the beat pulse input from the studio apparatus 21 (S27). Then, the period and timing of the sequence clock are controlled so as to be synchronized with the tempo and beat pulse timing (S28). This operation is always performed during the performance of the music, and the sequence clock is controlled in real time.

  FIG. 5B is a flowchart showing the lyrics sequence operation. This operation is executed at every clock timing of the generated sequence clock. First, it is determined whether or not a timing counter t for measuring a time interval between event data (corresponding to the timing data in FIG. 4B) is 0 or less (S30). Since the timer interrupt immediately after the start is reset to t = 0, the process proceeds from S30 to S32. In S32, the data indicated by the pointer indicating the reading position on the lyrics track is read. It is determined whether the read data is event data (S33), timing data (S34), or end data (S35).

  In the event of the lyrics track, as shown in FIG. 5, it is page break data or lyrics display data. If the data read in S32 is these event data (YES in S33), the process instructed by the event data is executed (S36), the pointer is advanced (S37), and the process returns to S32, and the next Read the data. When the lyrics display data is read as event data, the lyrics are displayed as described with reference to FIG. 5 based on the read timing.

If the read data is timing data (YES in S34), the value of this timing data is set to t (S38), the pointer is incremented (S39), and the process returns to S30. In S30, the value of t is determined. If t> 0, the countdown step value cs is subtracted from t (S31), and the process returns.
On the other hand, when the read data is the end data (YES in S35), the end processing of the lyrics sequence such as deleting the display of lyrics is executed (S40).
