Mixes these musical tone signals, chorus sound signals, and singing voices to give an effect, and outputs them to the speaker 5.

The DVD changer 4 has a plurality of DVDs 40
And read / reproduce. D
The VD stores a moving picture background video that has been MPEG-compressed. The background video includes an individual background video individually corresponding to a specific karaoke song and a general-purpose background video provided for each type (for example, genre) of the karaoke song. Since the individual background video is reproduced in synchronization with the corresponding karaoke tune, the performance location of the karaoke tune and the reproduction location of the individual background video are synchronized at respective timings. Also, individual background images are not sequentially arranged for all karaoke songs, and the general-purpose background image is reproduced for karaoke songs having no individual background images.

The DVD changer 4 and the pattern developing section 16 are connected to a display control section 17. The display control unit 17 superimposes a character pattern and the like developed by the pattern developing unit 16 on a background image input from the DVD changer 4 and displays the superposed image on the monitor 6.

The hard disk 12 stores music data of a large number of karaoke songs, a pseudo-scan image (see FIG. 9B) displayed when the currently playing karaoke song is fast-forwarded and rewound, and the like. Still image data, etc., to be displayed temporarily at the time of disk exchange or the like are stored.
The hard disk 12 also stores a pseudo-scan sound that is generated when the speed of fast-forward or rewind increases and the performance cannot catch up. This pseudo scan sound is a sound of “curky” that is output when the “cueing” or “repeating” operation is performed on the tape recorder. This pseudo scan sound is sent to the audio data processing unit 1
5 is decoded. The pseudo scan video is decoded by the sequencer 11 or the pattern developing unit 16 and input to the display control unit 17.

The karaoke apparatus shown in the functional block diagram of FIG. 1 is often constituted by a computer including a CPU, in which case the sequencer 11 and the pattern developing section 16 are provided.
Is realized in software by the CPU.

FIG. 2 shows the hard disk 12 and the DVD 40
FIG. 3 is a diagram showing a configuration of music data stored in the. The music data is composed of a header, a track group, and an audio data section. Bibliographic data such as song numbers and titles are written in the header. In the audio data part,
An audio signal such as a chorus sound reproduced by the audio data processing unit 15 is divided and stored for each phrase. The track group includes a music track that controls the sound source device 14, a lyrics track in which the pattern developing unit 16 writes lyrics data to be developed into a character pattern, and a timing at which audio data divided for each phrase is reproduced. Voice control track to be controlled, sound source device 14 and control amplifier 2
It consists of an effect control track for controlling the effect (effect).

The musical sound track is configured by arranging event data such as note event data and setting data and timing data indicating read timing of each event data in a time series. The timing data can be described by data such as duration data indicating a time interval between the event data and an absolute time from when the music starts to when the event data is generated. The sequencer 11 reads out the musical sound event data at the timing specified by the timing data and inputs the data to the tone generator 14. The tone generator 14 generates a tone according to the input tone event data.

The effect control track is configured by arranging effect control data, which is event data, and timing data indicating the read timing of each event data in a time series. The sequencer 11 reads out the effect control data at the timing specified by the timing data, and
4 or the control amplifier 2. Sound source device 1

The audio control track is configured by arranging audio designation data as event data and timing data indicating read timing of each event data in a time series. The sequencer 11 reads the audio designation data at the timing specified by the timing data, reads out the audio data (such as a chorus sound) specified by the audio designation data, and inputs the read audio data to the audio data processing unit 15. The audio data processing unit 15 reproduces this audio data and inputs the audio data to the control amplifier 2.

The lyrics track is sequence data that implements the title and lyrics of the karaoke song. As shown in FIG. 3, the lyrics track is composed of page break data and lyrics display data different from those of the track. The page separation data is data that separates the lyrics displayed on the monitor 6 on a line-by-line basis into those that are simultaneously displayed (2 to 4 lines), and corresponds to musical phrases of a karaoke song. The lyrics display data includes all data related to the lyrics display for one line, including display on timing, display off timing, character string data (including the number of display points, display coordinates, character spacing data, etc.), and one color data. , Color 2 data, scroll data, and the like.

The display mode of the lyrics is as follows. First, the lyrics of one line are displayed in color 1 and stopped for a while (until the song progresses to the location of the lyrics) in the same color (ton). , The display color is scrolled to change the color from color 1 to color 2 in order from the left. Finally, it is displayed in color 2 for a while (t
e) Erase afterwards.

The scroll data is composed of a plurality of plotting data indicating main points of a scroll (time-x coordinate) curve as shown in FIG. The sequencer 11 instructs the pattern developing unit 16 to change the color (scroll) by interpolating the plotting data with a quadratic curve.

In the lyrics display data, the display on timing data corresponds to the timing data of another track.

FIGS. 4 to 7 are flowcharts showing the operation of the karaoke apparatus. FIG. 4 is a diagram showing a sequence processing program (sequencer) for executing a karaoke performance. In FIG. 7A, first, the sequencer is initialized (s1). This initialization operation includes processes such as resetting a pointer indicating data on a track, resetting a duration counter t, and initializing (= 1) a duration countdown value cs. After that, the timer interrupt processing shown in FIG. In this timer interrupt processing, the same processing is executed for each track in parallel. However, data of all tracks may be merged and processed by one timer interrupt processing.

In FIG. 3B, first, it is determined whether or not the duration counter t is 0 or less. Since t = 0 is reset in the timer interrupt immediately after the start, the process proceeds from s5 to s7. In s7, the data on the track pointed to by the pointer is read. It is determined whether the read data is event data (s8), duration data (s9), or end data (s10).

In the case of event data, a process corresponding to the event is executed (s11), the pointer is incremented (s12), the process returns to s7, and the next data is read.

The event handling process (s11) differs depending on the type of the event data and whether normal reproduction or fast-forward or rewind described later is performed, and will be described together with the description of the remote control key operation.

If the read data is duration data (s9), the value of the duration data is set to t (s13), and the pointer is incremented (s1).
4) Return to s5. At s5, it is determined whether or not t is 0 or less. If t> 0, the countdown step value cs is subtracted from t (s6) and the process returns. This operation is performed every predetermined time (for example, every 10 ms).

On the other hand, if the read data is end data (s10), end processing such as all-note off and end display is executed (s15), and this timer interrupt processing is ended.

FIGS. 5 to 7 show the fast forward key 3 of the remote controller 3.
7 is a flowchart showing processing when a, a rewind key 3b, and a primary stop key 3c are turned on. This process
This is an interrupt process that is executed periodically (for example, every 100 ms). FIG. 5 shows a process when the fast-forward key 3a is turned on. The fast-forward operation is executed only while the fast-forward key 3a of the remote controller 3 is turned on. First, in s20, it is determined whether the fast forward key is turned on. If it is on, the process is executed only after the fast-forward key is turned on, that is, the fast-forward duration register tf = 0.
Is determined (s21). In the case of the first process, the fast forward preparation process (s22) is executed.

This fast-forward preparation process is as follows. It is determined whether the background video being reproduced in parallel with the performance of the karaoke song is an individual background, and if it is an individual background video, it is switched to a general-purpose background video. That is, the individual background video is completely synchronized with the performance of the karaoke song, and if fast-forward or rewind is performed, the performance cannot be synchronized with the video reproduction.

If D is currently set in the drive
When a general-purpose background video is not stored in the VD, a still image temporarily stored in the hard disk 12 is displayed, and in the meantime, a DVD storing the general-purpose background video is set in the drive, and the general-purpose background video is set. After starting video playback, switch from still image. On the other hand, when the general-purpose background video is displayed from the beginning, the display is continued as it is. Then, a status bar is displayed on the monitor (Fig. 9 (A)
) And a fast-forward mark (>>) on the OSD (on-screen display).

Thereafter, tf is counted up (s2
3) It is determined in which range the value of tf is (s2)
4, s25). Here, t1 and t2 are first and second threshold values, respectively, which are about 5 seconds and 10 seconds, respectively. If tf is equal to or less than t1, the countdown step value cs of the sequencer is set to 2. That is, the sequencer 11 (see the flowchart of FIG. 4) is set to play the karaoke tune at twice the speed of the normal reproduction. Then, it instructs the audio data processing unit 15 to reproduce the audio data such as the chorus sound at twice the speed in accordance with the speed setting. The processing of s26 and s27 is
When tf ≦ t1, it only needs to be performed once at first.

When tf exceeds t1 and becomes t2 or less, the countdown step value cs of the sequencer 11 is set.
To 3. That is, the sequencer 11 performs the normal reproduction 3
Set to play karaoke songs at double speed (s2
8). At this speed, even if the voice data such as a chorus sound is reproduced, it becomes unpleasant. Therefore, the sequencer 11 and the voice data processing unit 15 are instructed to stop the reproduction of the voice data, and the color change of the lyrics is performed. Since it is too late, the sequencer 11 and the pattern developing unit 16 are instructed to display the changed color from the beginning (s29). Note that the processing of s28 and s29 is t1 <t
When f ≦ t2, it is only necessary to perform the operation once at first.

Further, when tf exceeds t2, the countdown step value cs of the sequencer 11 is set to 4. That is, the sequencer 11 is set to play a karaoke song at four times the speed of normal playback (s30).
Then, the quadruple speed setting operation is executed (s31). The quadruple speed setting operation is the following process. Even if the sound source is driven based on the note data, it cannot be heard as a song, so the sequencer 1 stops driving the sound source device 14.
1 to reproduce a pseudo-scan sound during fast-forwarding (sound "curky"). This reproduction is performed by the audio data processing unit 15. Furthermore, in order to give a sense of speed to the display on the monitor 6, a pseudo-scan image (see FIG. 9B) during fast forward is displayed from the display of the general-purpose background image. Even in this case D
The VD changer 4 continues to reproduce the general-purpose background video. Note that the processes of s30 and s31 need only be performed once at first when t2 <tf.

In this fast-forward operation, cs = 2, 3,
Although acceleration was performed in three stages of 4, the number of stages of acceleration may be greater. Also, the degree of acceleration is twice, three times, and four times that of normal playback.
Although set to double, it may be finer or rougher than this. To make it finer, for example, cs = 1.5 is set. Even in this case, the sequencer 11 (see FIG. 4)
Can count down the duration data t in s3, and since s2 proceeds to the data reading process when t becomes 0 or less, the subtraction result does not need to be exactly 0.

On the other hand, when the fast-forward key 3a is not pressed, the process proceeds from s20 to s34. In s34, it is determined whether or not the fast-forward key 3a is turned off and the operation first proceeds to this operation. If it is not the first time, do nothing and proceed to the next processing operation (rewind processing operation: see FIG. 6).

If cs is greater than 1, fast-forwarding has been performed immediately before, indicating that this operation has been started for the first time (s34). In this case, the fast-forward duration counter tf is reset (s35), the countdown step value cs is returned to 1 (s36), and the return processing (s3) is performed.
Execute 7).

FIG. 8 is a flowchart showing the return processing. First, the general-purpose background video is reproduced and the display control unit 17 is operated.
(S71). If a general-purpose background video has already been reproduced, it is left as it is. Then, the status bar and the fast-forward OSD (>>) are erased (s7).
2). Then, a search is made to find where the pointer of the lyrics track has been moved by fast-forwarding (s73), and the nearest (previous) page delimiter data in the forward direction of the pointer is searched (s74). As described above, the position of the page break data is a break between karaoke song phrases,
Playing from here will make it easier for the singer to start singing. The time data on the karaoke tune at the position of the page separation data is determined (s75), and the time data is subtracted by several clocks and returned to the near side (s76) in order to allow time for singing. Then, after adjusting the pointers and the duration data of all the tracks to this time data (s
77), erases all sounds that were sounding during fast forward (s
78), a normal karaoke performance is started (s7).
9). That is, the timer interrupt operation is restarted in a normal state.

FIG. 6 shows the processing when the rewind key 3b is turned on. The rewind operation is performed only while the rewind key 3b of the remote controller 3 is turned on. First s40
To determine whether the rewind key 3b is turned on. If it is turned on, first, it is determined whether or not to execute this processing only after the rewind key 3b is turned on, that is, whether the rewinding duration time register tf = 0 (s4).
1). In the case of the first processing, the rewind preparation processing (s4
Perform 2).

The rewind preparation processing is as follows. First, an all-note off signal is output to the sound source, and the display of lyrics is also erased. And the sequencer 11
(See the flowchart of FIG. 4). A pointer indicating data on the track is s12,
At s14, the vehicle is moved backward instead of stepping. The note-off event is treated as a note-on event, and all velocities are constants (for example, 64). The lyrics display is displayed at the display off timing and erased at the display on timing. The color change wipe is performed in the opposite direction. The reverse color change wipe counts the time t from the display ON timing to the display OFF timing in the reverse direction, and the t is counted.
May be used to trace the wipe curve.

The background image displayed on the monitor 6 is replaced with the moving image reproduced by the DVD changer 4,
Switch to the still image stored in 2. That is, it is difficult to rewind and reproduce the background video (almost impossible in the case of MPEG). Another reason is that it is unnatural that only the video is played back in order when the music is played back in reverse. However, the DVD changer 4 continues the reproduction and switches only the screen in consideration of the case where the reproduction can be switched to the forward reproduction again. However, when the DVD changer 4 is playing back an individual background video, it is switched to a general-purpose background video. Change the disc if necessary. This is because the individual background video is completely synchronized with the performance of the karaoke song, and if the rewind is performed, the performance and the video reproduction cannot be synchronized. Then, a status bar (see FIG. 9A) is displayed on the monitor 6 and the OSD
(On-screen display) and the rewind mark (<
<) Is displayed.

Thereafter, td is counted up (s4
3) It is determined in which range the value of td is (s4)
4, s45). Here, t1 and t2 are first and second threshold values, respectively, which are about 5 seconds and 10 seconds, respectively. If td is equal to or less than t1, the countdown step value cs of the sequencer is set to 2. That is, the sequencer is set to play the karaoke tune in the reverse direction at twice the speed of the normal reproduction (s46). Then, a double reverse reproduction setting operation is performed (s47).

The operation for setting the 2 × reverse reproduction is as follows.
In response to this speed setting, an instruction is given to perform voice data such as a chorus sound in the opposite direction at twice the speed. In other words, it instructs the audio data processing unit 20 to thin out every other sampling data, read it out in the opposite direction, and input it to the audio data processing unit 20. Note that the processes of s46 and s47 need only be performed once at the beginning when td ≦ t1.

When td exceeds t1 and becomes t2 or less, the countdown step value cs of the sequencer 11 is set.
To 3. That is, the sequencer 11 performs the normal reproduction 3
Set to play in reverse direction at double speed (s4
8). At this speed, even if the voice data such as a chorus sound is reproduced, it is unpleasant. Therefore, it is instructed to stop the reproduction of the voice data, and the color change of the lyrics cannot be made in time. (S49). The processes of s48 and s49 need only be performed once at the beginning when t1 <td ≦ t2.

Further, when td exceeds t2, the countdown step value cs of the sequencer 11 is set to 4. That is, the sequencer 11 is set to reproduce in the reverse direction at four times the speed of normal reproduction (s50). Then, a quadruple speed reverse reproduction setting operation is executed (s51). The quadruple speed reverse reproduction setting operation is the following processing. Even if the sound source is driven based on the note data, the sound cannot be heard as a song. Therefore, the sequencer 11 is instructed to stop driving the sound source device 14, and a pseudo scan sound during rewinding (a sound called "curkyle") is reproduced. . This reproduction is performed by the audio data processing unit 15. Further, in order to give a sense of speed to the display on the monitor 6, the display of the still image is stopped, and a pseudo-scan image at the time of rewinding (see FIG. 9B) is displayed. The processes of s50 and s51 need only be performed once at the beginning when t2 <td.

In this rewind operation, cs = 2,
Although the acceleration was performed in three stages of 3 and 4, the number of stages of acceleration may be larger than this. Also, the degree of acceleration is twice that of normal playback, 3
Although it is set to double or quadruple, it may be finer or rougher than this. In the case of making finer, for example, cs = 1.5
Set to etc. Even in this case, the sequencer can count down the duration data t at s3, and since s2 proceeds to data reading processing when t becomes 0 or less, the subtraction result does not need to be exactly 0.

On the other hand, when the rewind key 3b is not pressed, the process proceeds from s40 to s54. In s54, it is determined whether the rewind key 3b is turned off and the operation first proceeds to this operation. If it is not the first time, do nothing and proceed to the next processing operation (pause processing operation: see FIG. 7).

If cs is larger than 1, rewinding has been performed just before, indicating that the operation has started for the first time (s54). In this case, the rewinding duration time counter td is reset (s55), the countdown step value cs is returned to 1 (s56), and a return process (s57) is executed. This return operation is the same as that at the time of fast-forward, as shown in FIG. 8, and therefore detailed description is omitted.

FIG. 7 is a flowchart showing the temporary stop control operation. First, it is determined in s60 whether or not the apparatus is currently in a pause state. The suspension state can be determined based on whether or not the countdown step value cs = 0. If it is not in the pause state, the process proceeds to s61.

At s61, it is determined whether or not the pause key 3c has been turned on. When the pause key 3c is turned on, all notes are turned off, the background video is frozen, the color of the lyrics is stopped, and a pause (II) is displayed by the OSD, so as to put the video player into a paused state. s62)
Is executed, cs is set to 0 (s63), a pause duration time counter tp for counting the pause time is set to 0 (s64), and the routine returns.

On the other hand, if it is determined in s60 that the pause has already been made, it is determined in s65 and s66 whether the pause key 3c has been turned on again or whether another performance control key has been turned on. . The other performance control keys are keys for changing the progress of the performance, such as a fast forward / rewind key, a start key, a redo key, and a performance stop key. When these keys are turned on, the flow advances to s69 to release the pause. First, cs is set to 1 to return to the countdown value of the normal reproduction, the pause display of the OSD is erased, and the normal reproduction of the background video is resumed.

As described above, by releasing the pause by turning on the other performance control keys, it is possible to eliminate the trouble of releasing the pause after performing the performance control. The pause may be released by another type of key, such as a key-con key. Also, fast forward key /
The pause may not be released by the rewind key.

If there is no key operation during the pause, the pause duration tp is counted up in s67. As a result of the counting up, when the suspension continuation time becomes longer than the predetermined time t0, the monitor 6
The pause is canceled even if there is no key operation in order to prevent burn-in (s68 → s69). t0 may be set to, for example, about 3 minutes. In the fast-forward and rewind processes shown in FIGS. 5 and 6, the ON state of the fast-forward key 3a and the rewind key 3b is detected and the corresponding process is performed. In the pause process of FIG. Since the processing is performed by detecting the ON event of 3c, the pause key 3
Even if c is kept pressed, the pause and the release are not repeated.

The above-mentioned t0 and the above-mentioned t1 and t2 may be fixed, or the setting may be changed in the serviceman mode.
