DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image supply apparatus, and more particularly, to an image supply apparatus for supplying a background moving image of karaoke to a display device.

[0002]

2. Description of the Related Art In a communication karaoke system, music data of a new music karaoke is distributed from a center to a cabin terminal through a telephone line, and the music data is pressed and recorded and manufactured until then. Compared to karaoke, this system provides karaoke songs instantly online and greatly reduces the time required for distribution.

FIG. 2 is a block diagram of an example of a conventional image supply apparatus applied to the above-mentioned communication karaoke, and FIG. 3 is a block diagram of an example of a communication karaoke system. The music data distributed from the center 50 of FIG. 3 via the telephone line is received and input to the music file group 17 shown in FIG. That is, conventionally, it is technically possible to distribute not only music data but also additional background moving images over a telephone line, but it is not practical in terms of cost and the like.
No. 6 distributes only music data composed of only additional information with a small amount of information such as lyrics characters and audio data of music by communication.

When the music data is input, the music file group 17 shown in FIG. 2 reads out the corresponding music file.
Since the music file input from the music file group 17 is composed of the code indicating the background moving image and the audio data and the lyric character data of the music, the music file expansion processing unit 18 separates them, and the code indicating the background moving image is the video C.
The audio data is supplied to the performance processing unit 13, and the lyric character data is supplied to the lyric character expansion unit 14.

The performance processing unit 13 decodes the input audio data and outputs an audio signal relating to the performance sound of the music of the received music data. The audio signal is amplified by the amplifier 62 of the karaoke terminal shown in FIG. . At this time, an audio signal (vocal sound) from the microphone 63 may be simultaneously emitted from the speaker 64. 2 decodes the input data and outputs a video signal indicating the characters of the lyrics of the music to the adder 30.

On the other hand, the video CD autochanger player 40 is provided with a plurality of video CDs (compact discs).
The video CD corresponding to the code selected and input by the operation terminal function 61 shown in FIG. 3 is reproduced from among them, and the video signal relating to the background moving image is output to the adder 30 shown in FIGS. As a result, the adder 30 outputs a video signal (video signal) in which the video signal of the lyric character from the lyric character expansion unit 14 shown in FIG. 2 and the video signal relating to the background moving image from the video CD autochanger player 40 are synthesized. Is output and displayed on the screen of the television monitor 65 of the karaoke terminal in FIG.

Here, a music CD that is conventionally sung in karaoke is divided into several categories by subjective evaluations such as the atmosphere and the tempo of the music, and a video CD on which a background moving image likely to match each category is recorded. Has been widely distributed, and is reproduced by the video CD autochanger player 40, and the reproduced moving image is used as a background moving image to be synthesized with music data provided by communication. Hei 3-427). In addition, the reproduction time of each background moving image is generally about 6 minutes to 12 minutes.

[0008]

According to the above-mentioned conventional image supply apparatus, a great effect was obtained for most music pieces, but music pieces of the same category use the same background moving image. For example, if you continue singing school songs, the same scenery will appear in any school song of any school, or if it is a land that appears as a theme in various songs such as Ginza, Yokohama, Kobe, the background image matching that will be reproduced, However, there was a complaint that even if they chose a local song from the local area, only the scenery of an unfamiliar land appeared, although the atmosphere was appropriate.

Conventionally, one video CD records one or more types of background moving images for each category, and it is usually necessary to prepare a plurality of such video CDs.

[0010] Furthermore, while the performance time of a music piece is mostly about 3 minutes to 6 minutes, some music pieces rarely exceed 12 minutes.
A background moving image of about 2 minutes to 15 minutes is prepared according to the genre and tune. Therefore, not only the background moving image having a length of about 3 minutes to 6 minutes but also the rarely reproduced 12 minutes to 15 minutes
Since a background moving image having a length of about one minute is prepared, 1/2 to 4/5 of the background is hardly reproduced, and the use efficiency of the video CD is wasted.

The present invention has been made in view of the above points,
It is an object of the present invention to provide an image supply device which can cope with various kinds of music pieces in a small capacity.

Another object of the present invention is to provide an image supply apparatus capable of reducing transmission costs from a center to a main unit and distributing images.

[0013]

According to the present invention, even if the supply of the same program is requested, the image material data can be reproduced in accordance with an instruction from the middle of the same table, so that the background information composed of a combination of different image material data can be supplied even with the same program information. it can.

Still further, according to the present invention, music data of a communication karaoke apparatus and image material data of a background image transmitted from a center via a line are received, and the received image material data is used as second information as an image material. It is characterized in that it is recorded as an independent file on a recording medium of a file group.

[0023]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an image supply apparatus according to the present invention. 2, the same components as those in FIG. 2 are denoted by the same reference numerals, and the description thereof will be omitted. The embodiment shown in FIG. 1 includes a communication karaoke apparatus main body 10, a background moving image supply apparatus 20, and an adder 30. The communication karaoke apparatus main body 10 includes a music file group 1
1, a music file development processing unit 12, a performance processing unit 13, and a lyric character development unit 14. This communication karaoke apparatus main body 10 is provided instead of the communication karaoke apparatus main body 16 when applied to the stand-alone communication karaoke system shown in FIG.

The music file group 11 shown in FIG. 1 is a device for receiving music data of a new music karaoke distributed from a center (not shown), storing the music data in a recording medium, and selectively reproducing the music data in response to a user request. For example, it is constituted by a hard disk drive (HDD). The music data includes a genre code, a pattern code, and image material data serving as a background image, in addition to audio data for performance sound of the music and lyric character data. In the music file group 11, a large number of music data are thus stored in the recording medium.

The genre code is a code indicating the genre of the music. The pattern code is a code indicating a series of time-series synthesis patterns of the image material when a background image of a certain length used together with the karaoke performance of the music is divided into a plurality of image materials. A plurality of patterns are prepared for songs that are often sung in karaoke, and a common pattern is used for a plurality of songs that are rarely sung.

On the other hand, the background moving image supply device 20 includes a background designation / material group conversion processing unit 21, a background moving image material file group 2
2, a buffer storage unit 23 and a compression / decompression processing unit 24, which are used in place of the conventional video CD autochanger player 40 shown in FIG. Together with the terminal function 61, the integrated set of FIG. The background moving image supply apparatus 20 may be configured to be built in the communication karaoke apparatus main body 10 which is a terminal apparatus.

The background designation / material group conversion processing unit 21 creates a table of image material data based on the pattern code and the genre code. The above table may be automatically generated each time the background moving image is reproduced by means such as random number, tune, and lyrics pattern recognition. Also, the background specification
The material group conversion processing section 21 may be provided in the communication karaoke apparatus main body 10.

The background moving image material file group 22 is composed of a plurality of image materials obtained by dividing a background image of a certain length used for karaoke performance of music into a predetermined length. This is a memory that stores a large number of image data compressed and encoded based on the image data as independent files.

Normally, one image material is a minimum of 1
The image data is reproduced for about several tens of seconds. However, an image material of an extremely short time is treated as a still image, and is used together with other moving image materials, for example, as a local famous thing or scenery in the middle of a song. Conventionally, a still image may be obtained as a result of a stationary camera work in a moving image. A still image is selected in consideration of the material in advance so as not to cause a sense of incongruity when inserted into a moving image. For this purpose, a background material list may be prepared and supplied together with music and still images / moving images. The operation of the background moving image material file group 22 can be stopped by an output control signal of the performance processing unit 13.

The buffer storage unit 23 stores the background image material file group 2
2 is a buffer memory for temporarily storing image data from the second memory. The compression / decompression processing section 24 is a circuit section for decoding the input image data and converting it into a video signal.

Next, the operation of this embodiment will be described. The music data distributed from the center 50 of FIG. 3 via the telephone line is the communication karaoke apparatus main body 10 of FIG.
Is received and input to the music file group 11 within the group. When the music data is input, the music file group 11 reads out the audio data for the performance sound, the lyrics character data, the genre code, the pattern code, and the image material data serving as the background image.

The music file development processing section 12 separates and inputs the image material data a to be the background image from the signal input from the music file group 11 to the background moving image material file group 22, and the image material data a is the music file group. No. 11 is not recorded as a file. Background video material file group 22
Accumulates (copies) the input image material data a as an independent file. Accordingly, the recording medium of the background moving image material file group 22 stores a large number of image material data for background images to be reproduced together with a large number of music pieces stored in the music file group 11.

In this state, if there is a request from the user, the requested music data is reproduced from the stored music data of the music file group 11 by a known means not shown. Music file development processing unit 12
In the playback music data input from the music file group 11, the pattern code and the genre code b are separated and input to the background designation / material group conversion processing unit 21, and the audio data is separated and transmitted to the performance processing unit 13. The character data is separated and supplied to the lyrics character developing unit 14.

The background designation / material group conversion processing section 21 creates a table indicating a combination of image materials to be reproduced as a background image in accordance with the input pattern code and genre code b, and outputs table data c. . Here, for example, when a song with the song name “Tsugaru Kaikyo Winter Scene” is input as song data, the background designation / material group conversion processing unit 21 creates a table as shown in Table 1, for example.

[0035]

[Table 1] Further, the background designation / material group conversion processing unit 21 generates an image material for the moving image of the “night train” of this table, an image material for displaying the still image of “Aomori Station distant view” for 15 seconds, , And table data c for instructing that the image material of the moving image of “Seikan Ferry” be reproduced in order, and output to the background moving image material file group 22.

Here, a plurality of patterns are prepared for a song that is often sung in karaoke. For example, when the song name of the song is “Tsugaru Strait Winter Scene”, two patterns as shown in Table 2 are used as backgrounds. This is prepared in the designation-material group conversion processing unit 21.

[0037]

[Table 2] Here, which of the plurality of patterns is to be selected may be switched in sequence each time a request is made, or may be switched randomly. In addition, it is conceivable that the pattern is not fixed as described above and is automatically generated by random numbers, but in this case, the intention of the producer of the music is not reflected, so this table is created with the background material and supplied online or offline. Is done.

Since there are, for example, more than 10,000 songs played in karaoke, the background designation / material group conversion processing unit 21
Creates a table so that a plurality of songs with similar characteristics share one table for songs that are not so frequently requested.

The background moving image material file group 22 reproduces, based on the table data c, the image materials specified in the table in the order specified by the recording medium and for the specified time. As a result, the image material is continuously and continuously played back from the background moving image material file group 22, so that time-series synthesized data of the image material is extracted, supplied to the buffer storage unit 23, and temporarily stored. After that, it is supplied to the compression / decompression processing unit 24, where it is expanded and decoded and converted into a video signal. This video signal is a video signal indicating a background image based on the table data c, and is supplied to the adder 30 to be supplied to the lyrics character developing unit 1.
After being synthesized with the video signal of the lyric character from No. 4, it is supplied to the image display device (TV monitor 65 in FIG. 3) of the karaoke terminal.

By the way, in karaoke, the performance of many songs ends in about 3 minutes to 6 minutes. In many cases, the background designation / material group conversion processing unit 21 creates the table assuming the performance time. . However, very rarely, there are songs whose performance time exceeds 12 minutes. In order to avoid this, if there are a plurality of candidate tables, the background moving image material file group 22 will continuously reproduce other candidates after finishing the background image of the image material based on one table. If the playback time of the background image is still shorter than the performance time of the music, the program returns to the beginning and plays endlessly. Even if there is only one table, it is reproduced endlessly in the same manner as described above.

On the other hand, when the performance processing section 13 detects the end of the audio signal of the music, that is, when the performance of the music is detected, the performance processing section 13 transmits the control signal d to the background moving image material file group 2.
2 to stop the operation. As a result, the background image can be continuously reproduced for a required time even when a music piece whose performance time exceeds 12 minutes is performed.

As described above, according to the present embodiment, the background image is divided not in the conventional music unit but in the material unit, and the divided background images are combined, so that different background images are supplied even for music of the same genre and tune. For example, even for school songs of the same genre, different background images can be supplied for different songs. On the other hand, the same image material can be shared by songs of different genres and tunes. For example, in the case of a song whose title is "Tsugaru no Joppi", most of the image materials of the table used in "Tsugaru Strait Winter Scene" in Table 1 can be shared except for "night trains".

The material serving as the background image is not a background image of one program divided into a plurality of pieces.
Since it is an independent image material that can be used as the background image of other music, even when a new program (background image) is distributed from the center to this device, only the minimum necessary image material needs to be distributed. Karaoke transmission costs can be reduced. Thereby, for example, when the theme song of a new program TV drama is started, one scene of the drama can be displayed, or a photograph of a new singer can be supplied in a timely manner by communication means.

The present invention is not limited to the above-described embodiment, and various other modifications can be considered. For example, the background designation-material group conversion processing unit 21
Instead of preparing a plurality of tables, a single table in which the image materials of the plurality of tables are continuously recorded may be created. In this case, even if the same music is requested, by reproducing the music from a different position in the middle of the table, a background image with a fresh impression can be provided every time even if only music having a similar tendency is requested. Also in this case, when the end of the background image material table is reached before the performance of the music ends, the process returns to the beginning of the table and continues playing the background image endlessly until the performance of the music ends.

Further, in the table examples of Tables 1 and 2, not only moving images but also still images are mixed as image materials serving as background images. It may be recorded in. In the case of a still image, its still time is also described in the table.
For a still image or a short-time moving image (for example, one frame), the start of reproduction of the image material to be reproduced next may be delayed while the video screen is frozen (still) for the time indicated on the table. Alternatively, the time indicated on the table
The image material may be played back repeatedly (even if a still video is played back repeatedly, it looks exactly the same because it is the same image).

Further, Japanese Patent Publication No.
No. 72026 (Title of Invention "File System"),
The present invention can also be applied to a multi-output type device, as disclosed in Japanese Patent Application No. 8-287480 (title of the present invention, "centralized karaoke system") proposed by the present applicant.

The composite video signal output from the adder group 30 'is transmitted to the communication karaoke apparatus main unit 1 compatible with multi-channel output.
The signal is supplied to the modem 73 together with the audio signal from 0 ', and after being modulated there, the signal is provided via the communication line 71 for each of a plurality of rooms of a karaoke box or provided for each room for a hotel CATV service. The karaoke terminal 70 is supplied to the karaoke terminal 70. In the karaoke terminal 70,
After the input signal is demodulated by the modulator / demodulator 72, the video signal is displayed as a background moving image on the screen of the television monitor 65, and the audio signal is emitted from the speaker 64 via the amplifier 62. A music request from the karaoke terminal 70 is made by operating a console 75, and the data is modulated by a modem 72, and then modulated via a communication line 71.
3 demodulated.

In this centralized communication karaoke system, the background moving image material file group 22 is read out of the image materials of a plurality of channels sequentially at high speed in units of amounts that can be stored in the buffer storage unit 23, and the input image data is stored in one buffer storage unit By sequentially switching and inputting each image material of a plurality of channels to the buffer storage unit of the corresponding channel so that the image material is input to another buffer storage unit within the time until the output is completed after the storage of the material, a plurality of Even when the same tune is selected from the karaoke terminal 70 at the same time, or when a tune already reproduced on another channel is requested from another karaoke terminal device, the same background image material can be supplied almost simultaneously. . In this case, the music file group 11 and the background moving image material file group 22 can be shared by the plurality of karaoke terminals 70, so that the overall size of the apparatus can be reduced.

In addition, sound may be mixed in addition to the image, and a commercial of a local store or a company can be played between requests. Also, the main body 10 and the background moving image supply device 20
