Description

  The present invention relates to a content reproduction apparatus that displays a video synchronized with an audio signal input from the outside.

  In the performance by the karaoke apparatus, the lyrics telop is displayed in synchronization with the performance of the music (for example, Patent Document 1). This is because the performance track for performance and the lyrics track for displaying the lyrics telop are previously stored in the song data in parallel.

JP 2000-99044 A

  The display of lyrics telop is to reproduce and display the telop synthesized with the video in advance, for example, live performance of live performance (so-called live relay), etc. Etc. was not displayed as a superimpose as a telop.

  In live performances, the progress of a song (jump) is often different from the progress of a song recorded and implemented in the song data of a karaoke song. For example, the number of refrain repetitions may be increased in accordance with the audience's excitement. In such a case, if the lyrics telop of the music data is displayed as it is, there is a problem that the performance and the lyrics telop are shifted.

  The present invention provides a content playback apparatus that can correspond to an external performance sound that is input in real time such as a live performance, and that can reproduce the video of the lyrics telop synchronously following the jump even when the song jumps. With the goal.

  The invention according to claim 1 stores music data including performance tracks that are time-series data of musical sounds of music and lyrics tracks that are time-series data for generating lyrics telop in synchronization with the progress of the music. An external performance sound input unit for inputting an external performance sound that is played from outside including a jump that is a progression different from the time-series data, and an external performance sound input from the external performance sound input unit Generating a performance position information synchronized with the performance position detecting section for detecting a jump of an external performance sound, and reading out a lyric track of the music data based on the performance position information detected by the performance position detecting section And a lyric telop generation unit for generating

  The invention of claim 2 further comprises a delay unit that outputs the external performance sound with a predetermined time delay, according to the invention of claim 1, wherein the performance position detection unit performs performance position information with respect to the lyrics telop generation unit. Is output with a delay of the predetermined time, and when the jump of the external performance sound is detected, the jump is output to the lyrics telop generation unit without delay.

  According to a third aspect of the present invention, in the first and second aspects of the invention, the lyrics telop generation unit displays the lyrics telop in advance from a predetermined time before the singing period and until a predetermined time after the singing period. The display is to be left, and immediately before the jump, the lyrics telop that has a singing period after the performance position of the jump source is not displayed in advance, and the lyrics telop with the singing period after the performance position of the jump destination is displayed in advance. It is characterized by that.

  According to a fourth aspect of the present invention, in the first to third aspects of the invention, the lyrics telop generation unit displays the lyrics telop in advance from a predetermined time before the singing period and until a predetermined time after the singing period. Immediately after the jump, the lyrics telop that has a singing period before the performance position of the jump destination is not displayed, and the display of the lyrics telop that has the singing period before the performance position of the jump source is left immediately after the jump. Features.

  According to a fifth aspect of the present invention, in the fourth aspect of the invention, the lyrics telop generation unit precedes the subsequent lyrics telop in accordance with a process of leaving a display of the lyrics telop having a singing period before the performance position of the jump source. The display timing is controlled.

  In the present invention, the lyrics telop can be displayed even in a live performance by generating the clock signal of the lyrics track from the external performance sound (mainly the performance sound of the live performance). In addition, since the performance position detector detects the jump of the external performance sound and causes the display of the lyrics telop to follow this, even if a jump such as repetition of the same phrase peculiar to live performance occurs, Can be followed.

A network live system according to an embodiment of the present invention will be described with reference to FIG.
This system, for example, connects a live venue or studio where a band is performing live with a karaoke box via a network, plays back the live performance video / audio on a karaoke device, which is a device on the karaoke box side, and karaoke This is a system that displays lyrics telop in live performance using song data for performance.

In FIG. 1, a studio apparatus 3 installed in a studio where live performance is performed is connected to a karaoke apparatus 1 that is an apparatus on the karaoke box side via a network 2.
The studio apparatus 3 includes a video / audio encoding unit 4, a song information input unit 5, and a song pointer generation unit 6. The video / audio encoding unit 4 encodes the performance sound of the live performance picked up by the microphone and the live video shot by the video camera into a digital streaming format such as MPEG4. The song information generation unit 5 generates information referred to search for a song being played live and / or information referred to detect a beat of the song. As information referred to search for a song, for example, there are a song number, a song name, a lyric to be sung, etc., which are numbers for designating a song by a karaoke apparatus. The information referred to for detecting the beat of the music is, for example, information such as a rough tempo and beat type. Here, the beat type is information such as the type of rhythm and whether or not it is an after beat. This music information may be generated by the operation of a live performance performer or a staff member, or may be automatically generated by a generation engine. The song pointer generator 6 generates a song pointer. The song pointer is information indicating the performance position of the live performance, and includes, for example, section information such as No. 1, No. 2, chorus, climax, intro, interlude, and ending. In the case of live performance, there is a case where the third chorus is omitted due to time restrictions, or the chorus is repeated in accordance with the audience's reaction, and the performance is different from the recorded normal performance. In such a case, the song pointer information is generated where the performance jumps out of the normal performance order (or prediction of where the performance is likely to jump). The song pointer generating unit includes a singing section list referring unit 7 and refers to the singing section list sent from the karaoke apparatus 1 when generating the song pointer. This song pointer may be generated by the operation of a live performer or a staff member as in the case of the music information, or may be automatically generated by a generation engine.

  On the other hand, the karaoke apparatus 1 includes the following functional units in addition to a normal karaoke song performance function (in this embodiment, description of functions of a normal karaoke apparatus is omitted). That is, a buffer 11, a video / audio decoding unit 12, a superimpose unit 13, a beat detection unit 15, a time code generation unit 16, a song search / lyric track extraction unit 17, and a lyrics telop generation unit (lyric renderer) 18 are provided. Yes.

  The video / audio data sent from the studio apparatus 3 is decoded by the video / audio decoding unit 12 and input to the buffer 11. Further, the audio data of the video / audio data is further input to the beat detector 15 in order to detect a performance beat based on the live performance sound. Here, the beat is performance information including a tempo (cycle) and beat timing. The beat detector 15 detects beats by extracting beats, that is, voice pulsations from the sound signal waveform (particularly the envelope), and detecting the period and timing of the pulsations. This beat detection is facilitated by filtering out the musical sound of a rhythm instrument such as a drum in the audio signal. When audio signals are sent in multiple tracks, beats may be detected using a rhythm part track.

  Furthermore, the beat detection unit 15 increases the accuracy of beat detection using the music information sent from the studio apparatus 3 and / or the music data sent from the music search unit 17. Since the song information includes rough tempo information of the song being played live, the basic beat interval is estimated based on the tempo information. Thereby, 1/2 beat is not counted as 1 beat when the rhythm is finely cut, and 2 beats are not counted as 1 beat when the rhythm is coarsely cut. The music data for karaoke performance includes a music track for generating a melody of a song being played live and an accompaniment tone (see FIG. 3). By comparing the audio signal sent from the studio apparatus 3, the beat detection accuracy can be increased. In addition, since the phrase of the song can be understood by reading the musical sound track, it is possible to predict the location of the drum fill-in (so-called “side dish”), and prevent the beats from being miscounted by the drum sound of the fill-in. it can.

  The beat detection unit 15 generates a tempo clock signal at a cycle and clock timing based on the beat detected by the above method. The tempo clock signal is input to the time code generation unit 16 and the lyrics telop generation unit 18. The time code generation unit 16 and the lyrics telop generation unit 18 are input with music data, which is data for karaoke performance of a song currently being played live, from the music search unit 17.

  The time code generator 16 is based on the tempo clock signal input from the beat detector 15, the song information sent from the song information input unit 5 of the studio apparatus 3, and the song pointer sent from the song pointer generator 6. Thus, a time code indicating the performance position on the music data is generated. The time code is an MTC code (MIDI Time Code) composed of measure number / beat / tick. Here, Tick is a clock count value obtained by dividing one beat into eight. The time code generation unit 16 advances Tick according to the tempo clock signal input from the beat detection unit 15, and determines where the current performance position is based on the song information and song pointer information. This MTC code is input to the lyrics telop generation unit 18. Note that the time code generated by the time code generation unit is not limited to the MTC code.

  Since the song information includes information indicating the type of rhythm (2 beats, afterbeat, etc.), even if the performance track of the song data is arranged with a different rhythm type, it is indicated by the song information. An accurate MTC code can be generated by tracing the musical sound track based on the tempo clock signal with the type of rhythm that has been set. Further, as described above, the song pointer information is information indicating the performance position of the current live performance, and includes section information such as No. 1, No. 2, chorus, climax, intro, interlude, and ending. With this song pointer information, even if the same melody is played, it is possible to identify whether the performance is the first performance or the second performance.

  Here, the time code generation unit 16 delays the transmitted video / audio by several seconds (about 5 seconds) in conjunction with the buffer (delay) 11. That is, the video signal / audio signal input from the input unit 20 by the buffer 11 is delayed by several seconds, and in conjunction with this, the time code generation unit 16 outputs the MTC code delayed by the same time.

  Further, the time code generation unit 16 detects the jump of the song being played live, that is, the progression of the song different from the progression recorded in the song data, and inputs it to the lyrics telop generation unit 18 in advance. The song jump is detected based on the song information and song pointer sent from the studio apparatus 3 as described above. As described above, the MTC code indicating the performance position is delayed by a few seconds in conjunction with the buffer 11, so that the MTC code jumps even when the song jumps suddenly, as well as when the song jump is known in advance. Before proceeding to the position, it is possible to inform the lyrics telop generation unit 18 of the jumping information such as the fact that the song jumps and the jump destination.

  The lyrics telop generation unit 18 determines a reading position based on the MTC code input from the time code generation unit 16, and generates and outputs a lyrics telop according to the tempo clock input from the beat detection unit 15. The lyrics telop is color-changed in synchronization with the progress of the music as shown in FIG.

  The lyrics telop generation unit 18 generates a video of the lyrics telop based on the tempo clock signal input from the beat detection unit 15 and the MTC code input from the time code generation unit 16. The lyrics telop is generated by rendering the position indicated by the MTC code of the lyrics display data shown in FIGS. 3 and 4 according to the tempo clock signal.

  Here, when the song jump information is input from the time code generator 16, the lyrics telop generator 18 is instructed by the lyrics display data to display the lyrics telop immediately before the jump and the lyrics telop immediately after the jump. The mode is changed to a mode suitable for the jump. Details of the change of the display mode will be described later.

  The lyrics telop generated and output by the lyrics telop generator 18 is input to the superimpose unit 13. The video / audio data decoded by the video / audio decoding unit 12 is delayed for a predetermined time in the buffer 11, and then the audio data is output as it is as an audio signal, and the video data is input to the superimposing unit 13. . The superimpose unit 13 superimposes the lyrics telop on the decoded video and outputs the synthesized text to the monitor. The decoded sound is also output to the speaker.

  Here, the buffer 11 delays the video / audio data input from the studio apparatus 3 for several seconds in conjunction with the time code generation unit 16. This delay time is a time corresponding to the processing time of the beat detection unit 15 → time code generation unit 16 → lyric telop generation unit 18 in addition to the delay time in which the time code generation unit 16 delays the output of the MTC code. Thereby, the lyrics telop generated and output in synchronization with the audio signal decoded by the video / audio decoding unit 12 and the video / audio signal decoded by the video / audio decoding unit 12 can be accurately synchronized. In addition, even when a song jumps, the display of the lyrics telop can be made to follow the jump position in synchronization.

  Note that the song search unit 17 searches for the currently played song based on the song information input from the studio apparatus 3, and inputs the song data of the song to the time code generation unit 16 and the lyrics telop generation unit 18. . Further, as shown in FIG. 3, a mark track in which a jump mark indicating the start point of the first and second singing sections is included in the music data. The song search unit 17 lists the contents of the mark track as a singing section list 19 and transmits it to the studio apparatus 3. The song pointer generation unit 6 of the studio apparatus 3 stores the transmitted song section list 19 and generates song pointer information by designating jump marks and the like included in the song section list 19.

  FIG. 2 is a block diagram showing the configuration of the karaoke apparatus 1. The karaoke apparatus 1 can play a karaoke song based on the song data stored in the hard disk 111 and reproduces the video / audio sent from the studio apparatus 3 as described above.

  The karaoke apparatus 1 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, a RAM 112, a sound source 113, a mixer (effector) 114, an audio decoder 119, a video decoder 120, a synthesis circuit 121, an operation unit 123, a network interface 124, 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. The buffer 11 in FIG. 1 is set in the RAM 112 and the hard disk 111.
The CPU 110 includes a music performance unit, a synchronization processing unit, and a lyrics telop generation unit as functional units executed by the program. The song performance unit plays a karaoke song using the song data 140. The synchronization processing unit executes the generation of the recovered clock shown in FIG. The lyrics telop generation unit generates the lyrics telop in synchronization with the performance of the karaoke song and the reproduction clock of FIG. The audio decoder 119 and the video decoder 120 correspond to the video / audio decoding unit 12 in FIG. The synthesis circuit 121 corresponds to the superimpose unit 13 in FIG.

  The sound source 113 generates a musical sound signal according to data input from the CPU 110 (note event data of a musical sound track or a guide melody track). The generated musical sound signal is input to the mixer 114. The mixer 114 echoes the musical sound signal output from the sound source 113 or the audio signal decoded by the audio decoder 119 and the singer's singing audio signal input via the microphone 117-A / D converter 118. In addition to providing an effect, these signals are mixed 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 video decoder 120 reproduces the live video sent from the studio apparatus 3 when the live performance video / audio data is reproduced. However, the video decoder 120 is stored in the HDD 111 during normal karaoke music performance. The video data 141 being read is read to reproduce the background video.

  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 network interface 124 is an interface for communicating with the studio apparatus 3 and the server apparatus via the network.

3 and 4 are diagrams showing the configuration of music data stored in the hard disk 111. FIG.
In FIG. 3, the music data includes a header, a musical sound 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 a mark track or the like on which jump marks indicating the song separation positions are written. On the mark track, for example, jump marks indicating the first, second, chorus, climax, intro, interlude, ending and the like are written.

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 lyrics track is sequence data that implements various data for displaying the song title and lyrics of the karaoke song, and has lyrics display data that is read based on the timing data, as shown in FIG. .

  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, lyric color change data, etc.

  With reference to FIG. 5B, the display mode of the lyrics telop by the lyrics display data will be described. In the graph of this figure, the vertical axis represents time and the horizontal axis represents the x-coordinate of the lyrics telop (monitor screen). Prior to ton when the performance of a song reaches the location of the lyrics, the lyrics for one line are displayed in advance in color 1. The singer needs to display the lyrics in advance in order to view and interpret the lyrics telop. The display continues in color 1 until the performance of the song progresses to the lyrics. When the performance of the song reaches the location of the lyrics, the display color is changed from color 1 to color 2 (wipe) in order from the left as the song progresses. After the wipe is completed, the telop is erased after being displayed in color 2 for a while (te).

  The color change data of the lyrics is composed of a plurality of plotting data indicating the main points of the wipe (time-x coordinate) curve as shown in FIG. The lyrics telop generation unit 18 functionally built in the CPU 110 interpolates this plotting data with a quadratic curve and changes the color (wipe). The lyrics telop generation unit 18 uses the beat detection unit 15 and the time code generation unit 16 to generate a lyrics telop that is accurately synchronized with the video / audio of the live performance and follows the jump of the song. In other words, the color change of the lyrics telop is accurately synchronized with the progress of the performance.

Here, with reference to FIG. 5 and FIG. 6, a change in the display mode of the lyrics telop in a plurality of lines and the display mode of the lyrics telop when the song jumps will be described.
FIG. 5 is a diagram for explaining a display format of a normal lyrics telop. In this figure, the horizontal axis represents the passage of time, and point A indicates the first singing, for example, and point B indicates the break (jump point) of the singing section such as the start of rust. The vertical axis in this figure corresponds to the Y coordinate of the monitor, and the strip-like figure shown in the figure shows the display position and display time of the lyrics telops a1, a2,. Represents. The signs of the lyrics telops a, b, c,... Represent the lyrics telop of the same phrase (display page), and the number after that represents the number of lines of the phrase. In the display time zone of each lyric telop, the central hatching portion indicates the color changing time zone of the lyric telop, that is, the singing time zone of the lyric telop, and the white belt portion on the left side of the hatching portion is the preceding display section (ton ), The white band on the right side of the hatched portion represents the remaining display section (te).

  In the same figure, the lyrics telops a1, a2, and a3 of the display page “a” of three lines are simultaneously displayed several seconds ΔT5 before the first singing. Then, the color change of the lyrics telop a1 is started from the singing point A, and the color change of a2 and a3 is performed continuously in accordance with the progress of the music without sequentially overlapping. Even if the singing (color change) of the first lyric telop a1 is finished, the display of this lyric telop is not erased immediately, and after a few seconds have passed since the singing has moved to the third lyric telop a3 Erase the lyrics telop a1 and lyric telop a2 in the second row at the same time. This is because if each lyric telop is erased immediately after the singing ends, the singer will have an impression that the screen is flickering. Erasing the lines at the same time reduces the impression that the screen flickers.

  After deleting the lyrics telops a1 and a2, the lyrics telop b1 of the next display page is displayed in advance. Then, after the singing has moved to the lyrics telop b1, the lyric telop a3 is left and displayed for a few seconds, and then the lyric telop b2 is displayed in advance. After the singing of the lyrics telop a1 ends and the singing moves to the lyrics telop b2, the lyrics telop b1 is deleted.

The next page c is a four-line display, but the lyrics telop b2 displays only the first-line lyrics telop c1 during the singing period. Then, after the singing moves to the lyrics telop c1 and the lyrics telop b2 is deleted, the lyrics telops c2, c3, and c4 are displayed in advance. Thus, when the singing moves from the last line (b2) of the previous page to the first line (c1) of the next page, only the lyrics telop of the first line of the next page is displayed and the lyrics after the second line are displayed. The telop (c2, c3) is displayed in advance during the singing of the lyrics telop c1. This is because, when the singer's line of sight moves from the lower lyrics telop b2 to the upper lyrics telop c1, if another lyrics telop is displayed on the way, there is a possibility that the line of sight cannot be smoothly transferred to the lyrics telop c1. This is because the lyrics telops c2, c3, and c4 in the second and subsequent lines are displayed after the singer's line of sight concentrates on the lyrics telop c1, that is, after the singing of the lyrics telop c1 starts. ing.
In the transition from the display page c to the display page d, the lyrics telops d2 and d3 in the second and subsequent lines are considered in consideration of the line of sight movement from the last line (c4) of the previous page to the first line (d1) of the next page Is displayed after the singing of the lyrics telop d1 starts.

  Note that the end of the display page d is the boundary of the singing section. Before and after point B, there are the remaining display of the lyrics telop d3 and the preceding display of the lyrics telop e1, but the singing (color change) is not performed.

  The control of the display mode when a song jumps while displaying the lyrics telop using the lyrics track created to display the lyrics telop in the above manner will be described with reference to FIG.

  FIG. 6 is a diagram for explaining the display control of the lyrics telop when the music jumps from point B to point A. As described above, by delaying the video signal / audio signal for several seconds, the lyrics telop generation unit 18 is notified of the jump information prior to the progress of the video / audio. Based on this jump information, display control is performed so that the display of the lyrics telop immediately before the jump and the display of the lyrics telop immediately after the jump are connected without a sense of incongruity.

  FIG. 4A is a diagram showing display control of the first mode. In this display control, the following processing is performed.

  Normally, the preceding display of the lyrics telop e1 that starts displaying immediately before point B is canceled. This is because there is no need to display the lyrics that are not sung.

  Just before point B (same as immediately before point A), the lyrics telops a1 and a2 are displayed in advance. This is because a prior display is necessary for the singer to keep up with the singing.

  Immediately after point A (same as immediately after point B), the remaining display of the lyrics telop d3 is performed. This is to erase the lyrics without a flickering feeling.

  For this reason, the preceding display timing of the lyrics telop a3 is delayed so as not to overlap with the remaining display of the lyrics telop d3.

  FIG. 5B is a diagram showing display control of the second mode. In this display mode, the following processing is performed in addition to the display control of the first mode.

  The remaining display of the lyrics telop d3 is rounded up earlier than the set time of the lyrics display data. This is to show that it is a break in the jumped song section. In the figure, the erasing is performed at the point B → A jump timing, but the timing is not limited to this.

  The preceding display timing of the lyrics telop a2 is delayed until the preceding display timing of the lyrics telop a3. As described above, in order to smoothly move the singer's line of sight from the lyrics telop d3 on the last line of the previous page to the lyrics telop a1 on the first line of the next page, the lyrics telop on the intermediate line is displayed. Because it is better not.

  By controlling the display mode like this, it is possible to realize display of a lyrics telop without any sense of incongruity even when a performance position such as live performance jumps.

  In the above description, the case where the jump of the song is performed from the boundary of the display page of the lyrics telop is described. However, the jump of the song is generally performed at the boundary of the phrase, that is, the boundary of the page of the lyrics telop. Since it is normal to jump, it is possible to cope with jumps of almost all songs by the display mode control.

  In the above embodiment, the network live system in which the studio apparatus 3 and the karaoke apparatus 1 are connected is shown. However, live performances in a wider venue may be distributed. The present invention can also be applied to a system for reproducing stock video / sound and jumping of a song during performance of a normal karaoke song.
