BACKGROUND OF THE INVENTION
The present invention relates to a background image display device for karaoke that switches background images at appropriate timing according to the contents of lyrics in so-called karaoke.
[0002]
[Prior art]
In a so-called karaoke device, when a user selects a desired song, a performance sound of the song is reproduced, and a background image (video) and lyrics of the song are displayed on a monitor. At this time, the displayed lyric characters are changed in color in accordance with the progress of the performance so that the progress of the performance can be visually understood.
[0003]
Conventionally, such an operation has been performed by simply reproducing an optical disk or the like containing a video signal (video signal) and an audio signal, but recently, when storing an optical disk. It may be performed by communication for a reason such as requiring a large space.
In karaoke by such communication, a host station and a karaoke device as a terminal station are connected via a telephone network or the like, the host station distributes song data selected by the terminal, and the terminal station chronologically generates musical sound generation events. The karaoke device, which is the terminal station, performs the specified performance data and the lyric data that indicates the display of characters in the song and the color change in time series in accordance with the progress of the performance. Sounds are generated according to the data, and characters are displayed and colors are changed according to the lyrics data.
[0004]
Now, it is difficult to distribute even a video signal by communication. For example, an optical disc containing a plurality of types of video signals is prepared in advance on the karaoke device side which is a terminal station, and the selected song is recorded. The music corresponding to the genre is separately reproduced and combined with the lyrics based on the lyrics data, so that the lyrics of the song and the background image are displayed on the monitor.
In addition, insertion data for instructing switching of video signals is added as music data, and background images are sequentially and appropriately switched in the performance process of one music.
[0005]
[Problems to be solved by the invention]
However, even if the video signal corresponding to the genre of music is played back, the performance music and the playback video do not correspond one-to-one, so that the background image to be played back is different from the atmosphere of the performance music There is. Furthermore, even if the music is different, the same background image may be reproduced, and there is a problem that the atmosphere does not rise.
Further, the method using the insertion data has a problem that it takes time to add the insertion data to the music data in advance.
[0006]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a background of karaoke in which a video that matches the content of a performance song is appropriately switched in accordance with the progress of the performance in a communication karaoke apparatus. An object is to provide an image display device.

As shown in this figure, the song data is displayed in accordance with the progress of the performance, the header indicating the composition information of the data, the performance data recorded in accordance with the MIDI standard, for example, data defining the content of the musical sound to be pronounced It is composed of lyric data in which lyric information to be recorded is recorded in time series.
Here, the performance data is composed of a plurality of tracks corresponding to the performance part, and each track is a collection of event data indicating the contents of events (for example, pronunciation, mute, etc.) that should occur in the performance part. ing. Between the event data, duration data indicating the time interval between the events is inserted. For example, when the event interval corresponds to a quarter note of a song, the numerical value “24” is inserted.
The lyric data includes, for example, display characters, display timing thereof, display character fonts, timing of color change, various data such as formats, and the like.
With this lyric data, for example, a lyric phrase as shown in FIG. 4A is displayed over a plurality of pages as shown in FIG. 4B.
[0014]
1-3: Database Next, the contents of the database stored in the fixed storage device 14 in the present embodiment will be described with reference to FIG. As shown in this figure, for the disks # 1 to # 36 held in the disk drives 31 _{1 to} 31 ₃ , for each track, a plurality of keywords (scene expression words) indicating the characteristics of the video recorded on the track are included. Described. In other words, an image reminiscent of an island, jungle, jungle, snake, danger, etc. (showing an uninhabited island jungle) is track No. 1 of disk # 1. 1 is recorded.
[0015]
2: Operation 2-1: Before Performance Next, the operation of the karaoke apparatus according to the present embodiment will be described. First, when a user who is a singer operates the operation panel SW to select a desired karaoke performance song, the CPU 10 sends the song data of the performance song via the modem 13 and the telephone network N to the host station. 20 to request. Upon receiving such a request, the host station 20 searches for the corresponding song data and transfers it to the karaoke apparatus as the terminal station. When detecting this reception, the CPU 10 loads the music data onto the RAM 12.
[0016]
At this time, the CPU 10 interprets the contents of the lyrics data in the song data, and determines, for example, a portion where the page interval of the lyrics to be displayed is longer than a certain value as a phrase break (see FIG. 4B). . Alternatively, a predetermined number (for example, five locations) of portions having a long page interval may be extracted from the order of the length. Then, the CPU 10 sets the point determined to be a break as the video switching timing.
[0017]
Next, the CPU 10 divides the lyrics indicated by the lyric data into phrases for each point determined to be a break, and detects words in each phrase. Then, the CPU 10 accesses the database of the fixed storage device 14 (see FIG. 5), and sets a video including the most frequently detected word as a scene expression word as a background image when the phrase is reproduced.
For example, when a phrase is formed as shown in FIG. 4A, first, each word of this phrase is detected. Here, for convenience of explanation, if the scene expression words in the database are limited to those illustrated in FIG. 5, it is the track No. 1 of disk # 1 that contains the most words in FIG. 2. Therefore, in this case, the background video when the phrase shown in FIG. 2 is set to the image of “the beach of the south island”.
The CPU 10 performs such setting of the background video for each of the divided frames that are determined to be divisions.
[0018]
2-2: Start of performance When various settings and the like are completed as described above, the CPU 10 executes the following processing for karaoke performance.
[0019]
First, the CPU 10 executes processing related to performance data. That is, the CPU 10 performs an interrupt process 24 times for each quarter note of the performance music, and decrements the duration data of the performance data by “1” each time the interrupt process is performed once. Here, the duration data becoming “0” indicates that the progress of the performance has reached the timing for performing the processing corresponding to the next event data, and therefore the CPU 10 corresponds to the event data. The process to do is performed.
[0020]
For example, if the event data is a note-on event, the data is transferred to the sound source circuit 15. As a result, the tone generator circuit 15 generates a tone defined by the note-on event data.
Then, after executing the process corresponding to the event data, the CPU 10 reads the value of duration data arranged next to the event data in order to prepare for the next event.
On the other hand, the fact that the duration data is not “0” indicates that the progress of the music has not yet reached the timing at which the processing corresponding to the next event data is to be performed. Therefore, the CPU 10 performs no processing on the performance. Absent.
The CPU 10 executes such processing for each track.
[0021]
Next, secondly, the CPU 10 executes processing related to the lyrics data. That is, the CPU 10 refers to the data indicating the time among various data included in the lyrics data, and when the progress of the performance reaches that time, the CPU 10 transfers the data related to the lyrics display to be performed at that time to the video circuit 18. . The time from the start of the performance can be obtained by counting the number of times the interrupt process is activated in the first process described above.
On the other hand, the DSP of the video circuit 18 rewrites the V-RAM in accordance with the contents specified in the transferred data.
As a result, the lyrics page is sequentially rewritten on the monitor 19 according to the progress of the performance, and the color of the lyrics characters is further changed.
[0022]
Thirdly, the CPU 10 controls the video at a timing set before the performance is started. That is, the CPU 10 instructs the corresponding disk drive 31 to play back the track set as the background image in the first phrase by detecting the break in the first phrase at the start of performance, and selects the output of the drive. The selector 32 is instructed, and further, one of the corresponding decoders 33 is instructed to decode the selected signal.
Thereby, in the first phrase of the performance, the background image reminiscent of the word with the highest frequency in the phrase is synthesized with the lyrics by the second process and displayed on the monitor 19.
[0023]
Next, when the progress of the performance reaches before the previously set break, the CPU 10 instructs the corresponding disk drive 31 to prepare for playing the background image and the set track in the next phrase. At the same time, the output of the drive is selected and the selector 32 is instructed to output to the other decoder 33.
When the progress of the performance reaches the previously set break, the CPU 10 instructs the corresponding disk drive 31 to reproduce the background image and the set track in the next phrase, and designates the switching. The mixer 34 is instructed to execute in the processed process.
[0024]
As a result, when the disk drives before and after the switching are different from each other, the background image switching is smoothly performed in the designated processing at the timing of the break between phrases. Also, if the disk drives before and after switching are the same, for example, the background image immediately before switching is stored in the memory and frozen to prevent slight blanking due to disk replacement, movement of the read head, etc. Processing is executed.
Note that the switching process may be, for example, instructing wipe or fade-in / fade-out by data previously specified by the user or added to music data.
Hereinafter, with respect to the background image, the same processing is repeatedly executed as the performance progresses.
[0025]
According to the karaoke apparatus of such an embodiment, the video can be switched for each phrase without creating the insertion data in advance, and the switched video matches the content of the phrase. can do. This prevents the video that does not match the contents of the lyrics from becoming a background image of karaoke, and also has an advantage that it can contribute to the excitement of the atmosphere.
[0026]
In the above-described embodiment, the lyrics are divided by the lyrics data and phrased. However, if the performance data includes a mark (for example, a section code or a bar line), this mark is used. Alternatively, the position of the lyric data corresponding to the point may be obtained, and the position may be used as a phrase to separate the lyrics.
[0027]
【The invention's effect】
As described above, according to the present invention, it is possible to appropriately switch the background image that matches the content of the performance song as the performance progresses.
