DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus that plays karaoke accompaniment music from a speaker, and displays on a display a lyrics image corresponding to the progress of the music and a background image corresponding to the mood of the music.

[0002]

[Prior art]

=== Mainstream Technology Just Before Appearance of Communication Karaoke === There are several types of karaoke devices depending on the type of content (karaoke software). A typical one is a type called laser karaoke (product name). In this type, content is produced and recorded on a storage medium as follows. The karaoke accompaniment music is actually played and recorded (audio signal is recorded). In addition, a mood video is produced and edited according to the atmosphere of the music, and a lyric image of the music is added to the mood video in advance so as to match the progress of the music. This is called a mood image with lyrics for music. As a storage medium, an optical analog video disk called a laser disk (trade name) is used. A composite signal in which an analog audio signal of karaoke accompaniment music and an analog video signal of a mood image with lyrics for music are appropriately modulated and superimposed is recorded on an optical analog video disk. A large number of such disks are copied and distributed to a number of karaoke apparatuses for loading. By playing a predetermined track of the disk containing the desired music on the video disk player of the karaoke apparatus, the accompaniment music of the music starts to be heard from the speaker, and at the same time, the mood image with the lyrics dedicated to the music is displayed on the CRT display as the music progresses. Is displayed.

[0003] Another typical karaoke device uses digital storage media that has been standardized as a video CD (the video CD standard is an advanced version of the karaoke CD standard in the first place). The content creation process is basically the same as the laser karaoke type. In other words, the karaoke accompaniment music is actually performed and recorded, and at the same time, a mood image with lyrics for each song is produced and edited. In accordance with the MPEG1 standard, the audio signal of the karaoke accompaniment music is digitally compressed and coded, the video signal of the mood video with the lyrics dedicated to the music is digitally compressed and coded, and the audio data and the video data are multiplexed to produce a video CD in music units. To record. A large number of such disks are copied and distributed to a number of karaoke apparatuses for loading. Karaoke device CD-R
When the OM player plays a predetermined track of the disc containing the desired music, the audio data and video data of the music are decoded, and the karaoke accompaniment music starts to sound from the speaker, and at the same time, the mood image with the lyrics dedicated to the music is displayed on the CRT display. Is displayed according to the progress of the music.

=== Communication Karaoke === A recent mainstream is a well-known communication karaoke. This is very different from the above two types in the mechanism for generating karaoke accompaniment music. Music software for general communication karaoke is DTM (Desktop Mu
sic), which describes music in a data format according to the MIDI standard. As is well known, MIDI data is not data obtained by digitizing an audio signal, but a control data sequence for controlling a synthesizer in a time-series manner to generate a music audio signal.

Digital audio data (hereinafter, referred to as DA data) obtained by digitally compressing and encoding karaoke accompaniment music recorded in a certain musical instrument organization, and synthesizing the same karaoke accompaniment music by a synthesizer to simulate almost the same musical instrument organization. When compared with MIDI data, MIDI data is overwhelmingly smaller in terms of data amount. However, since it is difficult to synthesize a realistic human voice chorus using a synthesizer, there are many songs that create PCM data that digitally records a chorus sung by a human and synchronize with the accompaniment music MIDI data. . The data amount is small enough in both cases.

[0006] By the way, MIDI data is mainly used to represent karaoke accompaniment music, and data of this format including karaoke chorus and other digital recording data (PCM data) is partially described. Notated as generated data. The karaoke generation data further includes lyrics rendering data. Lyric rendering data is data for graphics processing for superimposing and displaying lyrics in synchronization with the progress of karaoke accompaniment music, and includes lyrics character strings to be displayed, display layouts, display sequences, and singing timing instructions. Contains expression information.

Since the karaoke generation data can express the karaoke accompaniment music with a very small data amount (the attached lyrics depiction data is also sufficiently small), a small and inexpensive personal computer hard disk for a karaoke database of more than 10,000 songs. The device can be used as a storage medium and is practical. Also, for the same reason that the data volume is small, new karaoke software (Karaoke generation data and lyrics) can be transmitted to a large number of karaoke terminals that are operated over a wide area using digital communication media such as a telephone line network. A communication karaoke system of a system for distributing drawing data) from a host device could be easily constructed.

[0008] Even in a communication karaoke system, package media is usually used for a huge number of existing music pieces. In other words, C that records karaoke software (karaoke generation data and lyrics rendering data) of existing songs
A large number of D-ROMs are duplicated, and the karaoke software disk is stored in a CD-ROM player of the karaoke terminal device at the time of shipment. A communication system is used as a means for replenishing karaoke software for a new song not included in the disc.

[0009] When a karaoke accompaniment music is generated by processing karaoke generation data of a certain music in a communication karaoke terminal device, the corresponding lyric rendering data is synchronously processed and lyric images are generated in real time in accordance with the progress of the music. Generate a drawing and display it on the display. Displaying the lyrics is not enough. The background image is recorded on a video CD or the like, and is reproduced by a CD-ROM player in the terminal device. As described at the beginning, two types of karaoke devices using package media include a karaoke accompaniment music that is actually played and recorded, and a mood with lyrics specifically created and edited according to the mood of the music. The video was set as a set.
However, there is no lyrics-only mood video for online karaoke. A large amount of videos divided by an appropriate length are stored in a media such as a video CD as a shared video database, and the video selected appropriately according to the music is reproduced. Even if the number of songs in the music database is, for example, 10,000, and the total playing time is, for example, 10,000 × 4 minutes, the shared video database does not provide such a long moving image. Usually, there is only a video having a reproduction time of about one hundredth of the total playing time of the music. In the shared video database, video is divided into, for example, about 5 minutes in length, and each divided video is distinguished by a unique video ID. Several algorithms have been devised for deciding which video to select from the video database when playing a certain song. The method of classifying each video in the video database and the mechanism of associating each music with the video are devised so that the video that matches the atmosphere of each music is selected as the background video of the lyrics as much as possible.

[0010] The communication karaoke system is a large-scale computer network in which a huge number of karaoke terminal devices widely arranged on a nationwide scale and host devices operated by a business operator are connected by a communication line. It is also a multimedia system that handles audio information, textual video information, or moving image information. Therefore, in addition to the feature of quickly supplying new song software, various application functions using network resources are realized. For example, a communication karaoke company collects operation records of each terminal device through a host device, checks the function of each terminal device,
It realizes an extremely useful and advanced operation system and maintenance management system directly connected to the karaoke business, such as remote control of individual terminal devices based on operation records and contract contents. Furthermore, although not directly related to karaoke performance, various entertainment and information services linked to the karaoke usage environment have been conceived, and it can be said that this is an intelligent entertainment system that makes extensive use of network resources. On an evolutionary path.

[0011]

The karaoke accompaniment music created by controlling the synthesizer with MIDI data is compared with the DA data of accompaniment music that is digitally recorded by a leading performer as music. The quality, atmosphere, and sound quality of the sound are inferior.
Depending on the genre of the song or the composition of the instrument, this difference is a decisive negative factor, and the singer and listener's evaluation is significantly lower.

[0012] Also, watching a video displayed on the background of the lyrics while singing is a great pleasure especially for the listener. Enjoying the harmony between the content being sung and the content of the projected image is one of the entertainment elements for karaoke enthusiasts. In communication karaoke, the background video is selected while appropriately using the video from the shared video database, so even if you try to avoid an extreme mismatch between the music content and the video content, the mood with lyrics only for the music It is greatly inferior to those that use video.

Digital signal processing technology relating to audio and video redundancy compression and transmission is advancing rapidly, and high-quality recorded karaoke accompaniment music and mood video with lyrics dedicated to music can be converted into, for example, MPEG audio / video data. The construction of a communication karaoke system for transmission in a format has become less technically problematic.

However, actually performing and recording karaoke accompaniment music with a desired musical composition is much more expensive and time-consuming than producing karaoke generation data mainly using MIDI. Playing and recording high-quality karaoke accompaniment music without delay for all new songs that are created one after another places a great burden on software providers (karaoke providers). An even greater burden on software providers is the production of mood videos with lyrics specifically for songs. Creating a scenario that suits the content of each song, shooting and editing a short silent movie, is a daunting task. It is not easy to produce a mood video with lyrics dedicated to songs for new songs that are born about several tens of songs every month without delay, and it is extremely difficult to maintain the speed of delivery of new songs like current communication karaoke.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and has as its object to deliver new songs without delay and to provide a high-quality karaoke accompaniment music and a music-only mood that is in harmony with the contents of each song. To provide the video,
It is to balance at a high level.

BEST MODE FOR CARRYING OUT THE INVENTION

=== Center of Control System of Apparatus === A schematic configuration of a karaoke apparatus according to an embodiment of the present invention is shown in FIG. CPU1, RAM2, ROM3, HD
A computer such as a D (hard disk drive) 4 controls this device in a unified manner, and also plays a role in various data processing. The main body of the apparatus has an operation panel 5 for a user interface including a display and a keyboard, and a remote control receiver 7 corresponding to a remote control transmitter 6 is also attached. The operation panel 5 and the remote control receiver 7 are connected via a user IF (interface) processor 8 and a peripheral IF (interface) circuit 9 to C.
It is coupled to the bus of PU1. The karaoke user performs various operation inputs such as music selection using the operation panel 5 or the remote control transmitter 6 of the main body, and the operation contents, response information of the apparatus to the operation input, and various guidance information are displayed on the operation panel 5. Further, the CPU 1 includes the peripheral IF circuit 9 and the modem 1
0 is connected to a communication line network, and this device also functions as a terminal device of a communication karaoke system.

=== MPEG Type and MIDI Type =
== Karaoke content is exclusively stored on the DVD in the DVD (digital video disc) player 11, and a part of the content is also stored on the HDD 4. Karaoke contents in this device include MPEG type and MIDI, which have very different information expression mechanisms.
There are two types.

MPEG type content is karaoke A
It consists of V data and lyrics rendering data. The karaoke AV data is obtained by digitally compressing karaoke accompaniment music that has been actually played and recorded, and digitally compressing and encoding audio data for each song and mood video produced and edited according to the atmosphere of each song. This is data multiplexed with video data, and its data format conforms to the MPEG standard. Lyric rendering data is data for graphic processing for superimposing and displaying lyrics in synchronization with the progress of karaoke accompaniment music, and expressive information such as the character string to be displayed, display layout, display sequence, and singing timing instructions. Contains.

As the data recording format of the MPEG type music, for example, the lyrics rendering data is recorded immediately before the karaoke AV data, or only the lyrics rendering data is collected and recorded for a number of songs. Alternatively, lyrics rendering data can be multiplexed with karaoke AV data and recorded.

The MIDI type content includes MIDI data for controlling the synthesizer 22 to generate a synthesized sound of karaoke accompaniment music, and digital recording data (PCM data) such as a human voice chorus partially added to the accompaniment music. , Lyrics rendering data and video borrowing script data. The recording format of this data set may be the same as that of the conventional communication karaoke system, or another format may be adopted. In addition, MI which is the source of karaoke accompaniment music
The set of DI data and PCM data is called karaoke generation data.

The lyrics rendering data is data for graphic processing for superimposing and displaying lyrics in synchronization with the progress of the karaoke accompaniment music, and includes a character string to be displayed, a display layout, a display sequence, a singing timing instruction, and the like. Contains expression information.

The video borrowed script data is stored in the karaoke AV
In order to edit a background video by partially borrowing the mood video of each music piece of data (the main element of the MPEG type content), data representing chronologically identifying information of a plurality of video parts to be borrowed It is. This will be described in detail later.

=== Karaoke Database === A plurality of DVDs reproduced by the DVD drive 13 are used as main digital storage media, and the HDD 4 is used as an auxiliary digital storage medium, and the above-mentioned MPEG is used.
A database of karaoke contents of an enormous number of songs of type and MIDI type is constructed, and the database is managed mainly by the CPU 1. The DVD used in this embodiment is a read-only optical disk (DVD-
ROM), and a large number of disks on which data is recorded are copied and loaded into the DVD drive 13 of the karaoke apparatus.

In the karaoke content, there are as many as 10,000 existing songs, and in addition, new songs are generated at a rate of about several tens of songs every month. For new songs,
It is produced in the IDI type, and is distributed from the host device operated by the karaoke company to each karaoke device through the network of the communication karaoke system. In karaoke equipment,
The new music data of the MIDI type distributed from the host device is stored in the HDD 4, and a management record of the new music is added to the index file of the database.

As for existing music, there are music produced by the MPEG type and music produced by the MIDI type, which are appropriately divided and recorded on a plurality of DVDs.
For songs that require high-quality sound and appropriate mood images, such as constant popular standard songs,
Produce in PEG type. Of course, the production cost of the MPEG type is high. MIDI for old songs with few requests and new songs whose popularity is uncertain
Produce by type. The MIDI type is much cheaper than the MPEG type because the production cost of the karaoke generation data is low and the mood video dedicated to the music is not produced.

When a new DVD title containing new content is additionally distributed, even a song recorded in the old DVD title in the MIDI type has become popular thereafter, so it has to be re-produced in the MPEG type. There is no problem with recording.

The CPU 1 creates an index file in the HDD 4 to manage the karaoke database,
Update the contents as appropriate. In the index file, management records for each song using the song ID as a key are collected. The management record of each song includes information that indicates whether the data of the song is of the MPEG type or the MIDI type, and information indicating the storage location of the song data. Of course, various attribute information according to the intention, such as the title of the music, the name of the singer, the composer, the lyricist, etc., can be entered in the management record.

Management information is recorded in the header of each of a plurality of DVD titles loaded in the DVD drive 13. The header management information collectively describes what is recorded on each disk and at which position. The CPU 1 executes each of the DVDs loaded in the DVD drive 13 as one operation of the initial processing.
The header management information of the title is read, and the aforementioned index file is created based on the content. Also, as described above, the MIDI distributed from the host device is used.
The new music data of the type is stored in the HDD 4, and the management record of the new music is added to the index file of the database.

As the digital storage medium of the karaoke database, not only a read-only DVD or HDD but also various other media can be used. For example, use of a rewritable optical disk called a DVD-RAM, a write-once optical disk called a DVD-R, a magneto-optical disk, a mini disk (MD), an IC memory, and the like can be considered. It goes without saying that MIDI-type music data distributed from the host device by the communication system may be stored in a writable medium other than the HDD 4. Also, if a sufficient communication speed can be ensured, MPEG-type data is distributed from the host device to a number of karaoke devices, for example, a DV format.
It is also possible to store in the D-RAM.

=== MPEG Type Data Processing System ==
= The DVD controller 12 controls each unit of the DVD player 11 in a unified manner. The controller 12 is connected to the CPU 1 via the peripheral IF circuit 32, and operates the player 11 as instructed by the CPU 1. The DVD drive 13 has a plurality of disk changer-type drives arranged side by side, and can switch almost instantaneously from a reproducing operation of one disk to a reproducing operation of another disk.
First, the output of the DVD drive 13 is a demodulation / error correction circuit 1
4 and input to the MPEG decoder 15.
There is also a path for guiding the bit stream output of the demodulation / error correction circuit 14 to the bus of the CPU 1 via the peripheral IF circuit 32.

When an instruction is issued from the CPU 1 to the DVD controller 12 so as to reproduce the data of the music of the MPEG type (karaoke AV data and lyrics rendering data), the control of the controller 12 causes the player 11 to operate as follows. The disc containing the designated music data is reproduced by the DVD drive 13, firstly, the lyrics rendering data of the music is read and passed to the graphics circuit 20 via the MPEG decoder 15, and then the karaoke AV data of the music is reproduced. And input it to the MPEG decoder 15. Karaoke AV data is MPEG decoder 15
The audio signal processing circuit 18 and the video signal processing circuit 1 separate audio data and video data, respectively.
6, the analog signal of the karaoke accompaniment music is output from the DA converter 19, and the DA signal is synchronized therewith.
The converter 17 outputs an analog signal of mood video. The lyrics drawing data is processed by the graphics circuit 20 in synchronization with these processes, and the DA converter 1
The graphics data of the lyric image that changes in accordance with the progress of the karaoke accompaniment music output from 9 is generated. Thus, the audio signal A1 of the karaoke accompaniment music is transmitted from the DVD player 11 to the AV controller 27.
And the video signal V1 of the mood video and the graphics data G1 of the lyrics image are output. The audio signal A1 is amplified by the mixing amplifier 28 together with the singing audio signal from the microphone 30, and the karaoke accompaniment music and the singing sound of the user are emitted from the speaker system 29. At the same time, the mood image by the video signal V1 is displayed on the display 3.
1 and the lyrics image based on the graphics data G1 is superimposed and displayed on the same display 31.

=== MIDI type data processing system ==
= Receiving the requested song, the CPU 1 acquires the record of the song in the index file, and
When it is found that the music data is registered as the IDI type, it is recognized whether the music data is stored in the HDD 4 or the DVD drive 13, and a series of data of the music is read from the HDD 4 or the DVD drive 13. Read and write to the work area of RAM2. When the music data is stored in the DVD drive 13, the CP
U1 is the DVD controller 1 through the peripheral IF circuit 32.
2, the corresponding portion of the DVD title is reproduced, the reproduced signal that has passed through the demodulation / error correction circuit 14 is fetched through the peripheral IF circuit 32, and written into the work area of the RAM 2.

As described above, the MIDI type music data includes MIDI data for controlling the synthesizer 22 to generate a synthesized sound of karaoke accompaniment music, and digital recording such as a human voice chorus partially added to the accompaniment music. It is a set of data (PCM data), lyrics rendering data, and video borrow script data. Among the data expanded in the work area of the RAM 2, the MIDI data is passed to the MIDI processor 23, and the PCM data is transmitted to the PCM decoder 21.
The lyrics rendering data is passed to the graphics circuit 24, and the video borrowed script data is passed through the peripheral IF 32 to the DVD.
Transfer to controller 12.

The MI provided by the MIDI processor 22 is
By controlling the synthesizer 22 and the effector 25 according to the DI data, an analog audio signal of the karaoke accompaniment music expressed by the MIDI data is generated from the DA converter 26. In synchronization with the karaoke accompaniment music generation processing, PCM data such as a human voice chorus is decoded by the PCM decoder 21 and its output is mixed with the karaoke accompaniment music by the effector 25, and a karaoke accompaniment accompanied by a human voice chorus is provided. An analog audio signal A2 of music is output from the DA converter 26 to the AV controller 27. The graphics circuit 24 processes the passed lyrics rendering data in synchronization with the music generation processing, so that the graphics data G2 of the lyrics image that changes in accordance with the progress of the karaoke accompaniment music output from the DA converter 26. Is generated.

Thus, the audio signal A2 of the karaoke accompaniment music output from the DA converter 26 and the graphics data G2 of the lyrics image output from the graphics circuit 24 are supplied to the AV controller 27.
The signal path of the AV controller 27 is also switched under the control of the CPU 1, and the audio signal A 2 is amplified by the mixing amplifier 28 and the speaker system 29 is amplified.
, And the karaoke accompaniment music created by the synthesizer 22 sounds from the speaker. At the same time, the lyrics image based on the graphics data G2 is superimposed and displayed on the display 27.

In the above, the graphics data G2
Does not explain what is displayed on the background of the lyric image. The video signal V1 output from the DVD player 11 during the reproduction process of the MIDI type music described above is displayed on the display 3 via the AV controller 27.
1, this image is the background image of the lyrics image. How this background video is selected and output from the DVD title is defined in the video borrow script data included in the MIDI type music data. This will be described in detail below.

=== Background Borrow Script Data === It is assumed that the entire DVD title loaded in the DVD drive 13 contains MPEG-type content for, for example, 5,000 songs. In each of these songs, a dedicated mood video is recorded in the form of karaoke AV data. Assuming that the average recording time of the mood video of each music piece is, for example, 4 minutes, 5,000 × 4 minutes of video data exists in total. By borrowing this enormous amount of video data, a background video at the time of playing the MIDI type music is created.

As described above, the mood video of each song of the MPEG type does not include a lyric image, and can be borrowed as a background video for another song. The mood video of each music is recorded on a disc in the form of MPEG audio / video data, and the mood video of one music is divided into a plurality of parts by the concept of chapters, for example. Is distinguished by the part ID of the concept.

The DVD controller 12 has control means for operating the player 11 in the video independent playback mode. The video-only playback mode is an operation in which only video data in karaoke AV data recorded in a DVD title is partially played back and output. DV from CPU1
When an operation command of the video independent reproduction mode is given to the D controller 12 and a music ID and a part ID are given, the player 11 reproduces only the designated part in the mood video of the designated music and outputs it from the DA converter 17. .

The video borrow script data included in the MIDI type music data is a plurality of borrowed characters to be borrowed in order to partially borrow the mood video of the karaoke AV data of the MPEG type music and edit the background video. Is a data sequence in which a plurality of sets of music IDs and part IDs are arranged in chronological order. When playing a MIDI type song, the DVD is played according to the video borrow script data included in the song data.
The player 11 operates in the video single reproduction mode, and the video signal V1 sequentially output by the operation is displayed on the display 31 as the background video of the lyrics image based on the graphics signal G2.

The flow of the operation described in detail above is arranged in the flowchart of FIG. In addition,
The shared video that is not associated with the music is recorded as an appropriate DVD title in the form of MPEG video data and is converted into a database (the DVD is loaded into the DVD drive 13), and the shared video database is stored as MIDI type music. It is more desirable to add a function to be used for background images during performance.

[0053]

According to the present invention, it is possible to deliver a new song without delay and to provide a high-quality karaoke accompaniment music and a mood image dedicated to the song that is in harmony with the content of each song at a high level. Can be done. In other words, for songs that require high-quality sound and an appropriate mood image, such as a constant popular standard song, the karaoke AV data includes the karaoke accompaniment music actually played and the lyrics-free mood image produced specifically for the song. Prepare in the format. The cost of producing this content is high. on the other hand,
Old songs that have few requests, new songs whose popularity is uncertain, and new songs that will be replenished as soon as possible are produced in a data format such as MIDI for controlling a synthesizer to generate karaoke accompaniment music.
The production cost of this format of karaoke generation data is low,
The production of mood videos dedicated to music is not done, so production is easy and inexpensive. In particular, when performing the latter type of music, the former type of mood image is skillfully borrowed and displayed, which is extremely reasonable. In each case, the lyrics image is drawn on the display in real time based on the lyrics rendering data in accordance with the progress of the music.
