Abstract

PURPOSE:To obtain the KARAOKE device which displays music information in a multidimensional state when music to be played is reserved and make the reservation contents easy to confirm by making a retrieving music playing means start retrieving and playing music a specific time after a display means displays the music information. CONSTITUTION:A display information dictionary is set on an HDD(hard disk) 22C and when a music number is specified, the music number, music name, composer name, songwriter name, reservation order, etc., are displayed on a monitor 12. Then the requested music can be confirmed from the singer name, composer name, etc., when the same music name is displayed. For example, a right upper part on a screen is selected as the display place without impedance to music which is being played currently. Thus, the request contents need to be confirmed so as to evade unnecessary access when music data are inputted from a host station like musical sound synthesis type sound source KARAOKE. Further, music is frequently misselected even at the time of LD KARAOKE, so this is useful to evade the misselection.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke device which makes it possible to easily confirm the reservation contents by displaying the music information in a pluralistic manner at the time of reserving the performance music.

[0002]

2. Description of the Related Art A karaoke device having a function of reproducing a designated musical piece and mixing and outputting voices inputted from a microphone is not limited to restaurants such as snacks, but also karaoke boxes and buses. It is also popular in mobile units. An ordinary karaoke device has a storage system that stores performance information and image information, an acoustic system that reproduces a performance song and mixes the voice of a singer with it, and a video image that displays a background image and lyrics image according to the performance song. There are many types of musical sound reproduction types that include a system and a control system that controls each of these systems. On the other hand, recently, a musical tone synthesizing type karaoke apparatus has appeared in which necessary music data is taken in from a host station via a communication line. This musical sound synthesizing type karaoke apparatus has a built-in sound source for generating musical sounds based on music data.

The musical tone reproducing type karaoke device cannot respond to requests other than the musical composition stored in the storage system, but if the musical tone synthesizing type karaoke device is used.
Since it is possible to have the song data supplied in response to the singer's request from many song data stored in the host station, in an extreme example, even if there is no song data on the karaoke device side, It will be possible to meet all requests from the singer. The complete tone synthesizing karaoke device has such a configuration, but in order to reduce the communication fee and communication time for accessing the host station each time a request is made, a storage device is provided on the karaoke device side and the karaoke device is loaded from the host station here. There is also a semi-tone synthesis type that stores song data and reuses it.

In any type of karaoke device,
In order to reproduce a desired music piece, it is necessary to input a music number for specifying the music piece to be played, using the front panel of the main body of the apparatus or a remote controller separate from the main body. It is generally called "reservation" because the input of the song number can be performed while playing another song. The reserved musical pieces are played back according to the order of reservation, so the singer may wait for his turn to arrive. However, the reservation method of inputting only the song number involves mistakes in song selection. In many cases, this mistake in selecting the music is not noticed until the music piece that is actually selected incorrectly is played.

[0005]

Since a mistake in selecting a song interferes with the progress of playing a plurality of performance songs in order, it is desirable that it can be avoided regardless of the type of karaoke device. Some monitors display the reserved song number on the lyrics display monitor, but do not display more song information, so it is generally difficult to intuitively check which song has been reserved from the monitor display. Met. Nevertheless, in the musical tone reproduction type karaoke apparatus having all the performance information, if the reservation is made correctly again, the performance of the corresponding song will be started soon, so that a mistake in selecting a song merely delays the start of the desired performance song. However, in the case of the musical tone synthesizing type karaoke apparatus, the music data of the music number of the selected music may be accessed by the host station to search, which causes an economic disadvantage due to useless communication line. SUMMARY OF THE INVENTION It is an object of the present invention to provide a karaoke device which improves the above-mentioned points and multi-displays music information at the time of reserving a performance music so that the reservation contents can be easily confirmed.

[0006]

In order to achieve the above object, according to the present invention, in a karaoke apparatus for inputting a music number of a desired music piece and selecting the corresponding music piece, when the music piece number is inputted, the music piece is inputted. In addition to the number, the song name, composer name, and lyricist name of the corresponding performance song are displayed on the monitor.Furthermore, after the monitor display, a predetermined time elapses so that the wrong song is not searched or played. The feature of the present invention is that the music piece is not searched and the cancellation of the performance piece is accepted during that time.

[0007]

[Function] When confirming the reservation contents, it is difficult to intuitively confirm which song has been reserved only by the song number, but if the song name of the playing song is displayed, it is immediately confirmed whether the song is the song the singer desires. can do. In some cases, the same song name and different performance songs may be used, so by displaying the composer name and the lyricist name together, it is possible to further prevent mistakes in song selection. By displaying such multi-dimensional song information at the time of reservation and accepting the cancellation for a predetermined time, the singer or the person in the shop who notices the mistake in selecting the song can immediately cancel the operation. It is possible to avoid waste such as accessing the wrong song to the station.

Reference numeral 71 denotes an ISDN for the storage device 22C.
It is a portable downloader used when loading a large amount of song data without using the line 40. For example, it should be brought in and loaded by the installer at the initial stage when the tone synthesis system of this system was installed. Thus, the installer side does not have to communicate with the host station 30 through the ISDN line 40 for a long time. Other uses of the download machine 71 are possible.

The tone generator processor 23C is a so-called music synthesizer which is driven by song data and synthesizes tone signals of a performance song. For example, the tone generator processor 23C includes a tone generator unit which synthesizes tone sounds based on MIDI signals, and a control unit which controls the tone generator unit. ing. The video processor 23D processes character information such as lyrics corresponding to a performance song and background image information such as a still image and a moving image to generate an image signal for display. Here, an example is shown in which the video processor 23D1 for the lyrics image and the video processor 23D2 for the background image are used. The LD changer 11 functions when playing a karaoke piece recorded on an optical disk, or when playing only video information, and when used as a musical tone synthesis system, in synchronization with the accompaniment performance synthesized by the sound source 23C, Video information including a still image of a predetermined frame of a predetermined disc or a moving image having a predetermined frame as a starting point is reproduced. The video selector 23E combines these three types of images into one screen and outputs the combined image.

The operation will be described below. "Music reproduction / music synthesis control" When a music piece is specified by operating the remote controller 24 or the front panel 50, C
The PU 61 refers to the index table stored in the storage unit 22C and displays the song title and the composer name on the display 12. After that, when the cancel signal is not confirmed after waiting for a predetermined time to receive a cancel signal from the remote controller 50 or the front panel 24, whether there is data of a song corresponding to the LD in the LD changer 11 as the first rank. Confirm whether or not, and if there is, play that part. The video signal from this LD is the video selector 23.
The audio signal is input to E and displayed on the monitor 12, and the audio signal is input to the audio DSP 70 and output from the speaker 15. The singing voice of the singer is converted into an electric signal by the microphone 14 and input to the audio DSP 70 through the microphone effector 69. Since the mixer 13 mixes the performance music and the singing voice, the speaker 15 produces a mixed acoustic output.

When the designated song is not in the LD changer 11, the CPU 61 searches the song held in the HDD device 22C as the second rank. If there is a corresponding song in the HDD device 22C, the song data of the played song is read out and R is read.
Loaded to AM62 and sound source 23C according to this song data
The musical sound is synthesized with and a karaoke performance is performed. The performance of such a sound source karaoke is performed under the control of the sequencer 23B. With respect to the musical piece to be played, musical tone information is successively generated in the tone generator processor 23C in accordance with the musical piece data read from the RAM 62, and is reproduced from the speaker 15 via the mixer effector 68, the audio DSP 70, and the mixer 13.

Regarding the image, similarly, based on the music data read from the RAM 62, the video processor 23D1 and 23D2 generate the lyrics image and the background image according to the progress of the music in accordance with the instruction of the sequencer 23B.
It is displayed on the monitor 12 via the video selector 23C. When the background image from the LD changer 11 is also used, these three images are combined and displayed by the video selector 23E. The lyrics image displayed on the monitor 12 is instructed so that the singer can easily understand where to sing because the color of the displayed lyrics is changed to a character of another color according to the progress of the singing. It Therefore, the singer is monitor 1
Sing with the microphone 14 while watching the lyrics image displayed in 2.

When the corresponding song data is not stored in the HDD device 22C, the CPU 61 controls to fetch the data of the relevant song online from the host station 30 as the third rank. That is, the ISDN line 40 is used to call the host station 30, and when it responds, the music number is sent and the corresponding music data is transferred. Since the music data may be reused, it is stored in the HDD device 22C.

"Information Display of Reserved Music" In a normal karaoke apparatus, when the reserved operation of a performance music is performed, only the music number of the music is displayed on the monitor. Therefore, it is often the case that the request error is not noticed until the performance is actually started. In order to improve this point, as shown in FIG.
When the display information dictionary is set in the DD22C and the song number is designated, the song number, song name, composer name, lyricist name, reservation order, etc. are displayed on the monitor 12, and the same song name is displayed from the displayed song name. If so, the requested song can be confirmed in advance from the singer's name, composer's name, etc. The place to display is
For example, the upper right corner of the screen is selected so as not to hinder the currently playing song.

Such confirmation of the request contents is necessary for avoiding unnecessary access when music data is fetched from the host station as in the case of musical tone synthesis type sound source karaoke. In addition, even in LD karaoke, a mistake in selecting a song is common, and it is useful for avoiding this.

The contents of the display information dictionary in the HDD 22C are as follows:
It is updated when downloading through the ISDN line, and song information up to the latest song is always stored. Front panel 2
4 or the remote controller 50 newly designates a desired song number, the CPU 61 searches the display information dictionary in the HDD 22C and reads the song name, composer name, and lyricist name of the corresponding song number together with the song number, These are displayed on a part of the monitor 12 together with the reservation order.

Since the user can immediately confirm whether or not the desired song selection has been made from the displayed song information, if he / she notices that he / she has made a song selection mistake, he / she can immediately cancel the reservation by operating the remote controller 50 or the like to cancel the reservation. It can be carried out. Also, the song name, composer name, etc. are displayed so that they can be canceled for 5 to 20 seconds if an input error is noticed, and if there is no cancellation during that time, the host station is accessed. The CPU 61 uses the LD changer 11 and the HDD 2 for the song numbers whose reservations have been canceled.
Since the 2C search and the access to the host station 30 are not performed, it is possible to avoid wasteful processing time and cost consumption related to these.

[0031]

As described above, according to the present invention, the music information is displayed in a multi-dimensional manner at the time of reserving a performance tune so that the user can intuitively confirm the reservation content and search for a mistake in input music. It is possible to provide a karaoke device that can be corrected before playing.
