2. Description of the Related Art In recent years, various karaoke recording medium reproducing apparatuses using optical disks have been developed. As one of the methods, there is a method in which a karaoke piece and a background image of the karaoke piece are recorded on different optical disks, and the optical disk of the karaoke piece and the optical disk of the background image are reproduced at the same time.
In this method, karaoke music data with a small amount of data and image data with a large amount of data are recorded on separate disks, and the number of karaoke songs is increased compared to the number of background images to answer various requests of karaoke users. It is what

And, as described above, many optical disks are
Managed by a disc changer. After the reproduction of the karaoke music, the optical disk is exchanged by the disk changer in order to reproduce the next karaoke music. However, it takes time to exchange the optical disc by the disc changer, and the karaoke user waits during this period. Therefore, various countermeasures have been considered, such as reducing the waiting time, or outputting an image or the like even during the waiting time so as not to get bored.

An invention which is a countermeasure against the problem is disclosed in, for example, Japanese Patent Laid-Open No. 4-191882. This is a music information storage medium in which image data which is karaoke music and lyrics information is recorded, and an image information recording medium in which moving image data which is a background image is recorded are simultaneously reproduced. During the exchange of the disc which is the image information recording medium, the last image of the moving image of the image information recording medium used in the karaoke piece is read into the memory unit and output as a still image.

[0005]

However, in this case, two discs, which are a music information storage medium and an image information recording medium, are used.
There is a drawback that it takes time by exchanging the pieces, and new karaoke songs cannot be played until both recording media are ready. Further, when the number of the discs as the image information recording medium is only one, the exchange time can be shortened by changing only one optical disc as the music information storage medium, but the number of times is limited because the image information is limited. The same image was seen, which had the drawback of adding freshness.

[0006]

In order to solve the above problems, in the invention according to claim 1, in a karaoke recording medium in which moving image data for background image and still image data are recorded, the still image data is the moving image. It is characterized in that it is image data having a relationship with a moving image obtained by reproducing the image data.

[0007] According to the second aspect of the present invention, the first aspect is provided.
In the karaoke recording medium described above, the still image data comprises a part of the moving image data.

Further, in the invention of claim 3, in the karaoke recording medium reproducing apparatus for reproducing image data composed of karaoke music data, moving image data used for background image data and still image data used for background image data, the karaoke A changer unit for accommodating and exchanging a recording medium for music data and image data, a reproducing unit for reproducing the recording medium, a memory unit for storing the image data, and a key input for inputting karaoke music selection and reproduction stop information. Section, a monitor section for outputting the image data,
The changer unit, the reproducing unit, the memory unit, and the control unit to which the key input unit is connected, the control unit instructs the changer unit to replace the recording medium on which the karaoke piece to be reproduced next is recorded, The still image data related to the karaoke song is written in the memory unit from the recording medium that has been used so far, and the changer unit is instructed to replace it with another recording medium in which the image data corresponding to the next karaoke song is recorded, and the result is recorded. While the medium is being replaced, a still image in the memory section is displayed on the monitor section, and if it is detected that the next karaoke piece is ready for reproduction, the reproducing section reproduces the karaoke piece, and the moving image data is displayed. If it is detected that the preparation for playback is completed, the output of still image data from the memory unit is switched to the output of moving image data from the playback unit. And wherein the door.

Further, according to the invention described in claim 4, according to claim 3,
In the karaoke recording medium reproducing apparatus described above, the control unit changes and outputs the still image from the memory unit while the recording medium is being replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a karaoke recording medium reproducing apparatus according to the present invention. The operation input unit 1 is connected to the control unit 2, and the control unit 2 obtains a control signal from the operation input unit 1. In addition to this, the control unit 2 includes a disc changer unit 3, a karaoke music reproducing unit 4,
The karaoke music memory unit 5, the background image reproducing unit 6, and the background image memory unit 7 are also connected, and these operations are performed by the operation input unit 1.
It is controlled according to the input from.

The disc changer unit 3 accommodates a large number of optical discs. There are two types of optical disks: a karaoke music disk 8 on which karaoke music is recorded and a background image disk 9 on which moving images and still images are recorded. The karaoke music disc 8 taken out from the disc changer unit 3 is reproduced by the karaoke music reproduction unit 4, and the background image disc 9 is reproduced by the background image reproduction unit 6.

Further, the karaoke music reproducing section 4 is connected to a karaoke music memory section 5, and the background image reproducing section 6 is connected to a background image memory section 7, so that the karaoke music reproducing section 4,
Alternatively, the output data from the background image reproduction unit 6 is temporarily stored.

Further, a karaoke music monitor unit 10 is connected to the karaoke music memory unit 5, and a background image monitor unit 11 is connected to the background image memory unit 7, and the karaoke music memory unit 5 and the background image memory unit 7 are connected. The output data from is output in a format that can be perceived by humans as a voice or an image.

Next, the operation method will be described. When using this karaoke recording medium reproducing apparatus, the singer inputs from the operation input unit 1 to the karaoke recording medium reproducing apparatus, which karaoke piece is to be sung, what volume the volume should be, and the like. The operation input unit 1 sends a control signal to the control unit 2, and the control unit 2
Is a karaoke music disc 8 on which a karaoke song desired by the singer is recorded and a background image disc 9 from the disc changer unit 3 by a disc exchange mechanism (not shown), and the karaoke music reproduction unit 4 and the background image reproduction unit 6 respectively record the discs. Control to place.

The karaoke music disc 8 is used by the karaoke music reproducing unit 4, and the background image disc 9 is used by the background image reproducing unit 6.
Are played respectively. These are synchronized to some extent by the control unit 2, so that the background image output and the karaoke music output are not uncomfortable for human senses.
The karaoke piece data is stored in the karaoke piece memory unit 5, and the background image data is stored in the background image memory unit 7.

At this time, if the karaoke recording medium reproducing apparatus is used for the first time, only moving image data will be output without outputting still image data. This is because still image data cannot be stored in the background image memory unit 7 because the background image disk 9 is not mounted. The karaoke song memory unit 5 and the background image memory unit 7 store the read data, and can output the data for several seconds even if the reading of the data fails. It is possible to send the data periodically by adjusting the accurate output timing of the image data.

Then, the karaoke music monitor 10 and the background image monitor 11 output the output data in a format that can be perceived by a person as voice or video. While listening to and listening to this, you will enjoy karaoke using a microphone (not shown).

FIG. 2 shows a block diagram of a background image disk 9 which is a karaoke recording medium according to the present invention. The disc changer unit 3 accommodates two or more optical discs. There are two types of optical discs, a karaoke music disc 8 and a background image disc 9. Here, for the sake of explanation, it is assumed that 50 pieces of karaoke music discs 8 and 10 pieces of background image discs 9 are stored in a concrete manner. Also,
The karaoke music disc and the background image disc 9 both have a diameter of 12 cm, which is the same as a compact disc, and the data amount which can be recorded in a CD-ROM using the compact disc as a ROM is about 640 Mbytes.

It is assumed that the karaoke music disc 8 has a total of 72 songs, each of which has 18 songs of about 4 minutes and lyrics data, and has a total of 900 karaoke songs for 50 songs. Since the moving image data corresponding to MPEG1 having one song of 5 songs has a capacity of about 50 Mbytes, a maximum of 12 songs of 600 Mbytes can be recorded on the background image disk 9. However, about 550 Mbytes of 11 songs are recorded with room to input still image data.

Still image data is put in the remaining 90 Mbytes. Assuming that the still image data is the data obtained by cutting out the first 40 seconds of each 5 minutes of moving image data one by one per second, the capacity of the still image data is 1/10000 of the moving image data. Is about
A total of still image data corresponding to 110 moving image data has a capacity of several Mbytes. Therefore, still image data can be recorded on the background image disk 9 with a margin. Here, the number of background image discs 9 is, for example, 100.
Even if the number of still images is set, the total still image data is several tens of Mb.
It has a capacity of yte and can handle an increase in the number of sheets.

A total of 110 moving image data are recorded separately on 10 background image disks. Background image disk No. Video data No. 1 1 to No. 11 is
Background image disk No. Video data No. 2 12
-No. 22 is the background image disc No. 1
Up to 0, 11 moving image data are recorded on each background image disc.

At the end of each background image disc, 11
Other than the moving image data of No. No. 1 to No. No. 110 still images corresponding to all. No. 1 to No. Up to 110 are recorded.
No. of moving image data. No. 1 of still image data. For example, 1 means that when the moving image data is a landscape of the sea, the still image data is also a landscape of the sea, and is recorded without a different landscape when switching from the still image data to the moving image data.

At this time, frame numbers are assigned to the 40 still image data. The frame number of the still image data output when the moving image data becomes reproducible is read out to the control unit. If the frame number is 29, moving image data can be naturally connected by switching 30 seconds after the beginning.

Still image data may be produced not to be cut out from the moving image data but to be naturally connected to the head of the moving image data. For example, the title of a karaoke song is output from a karaoke song disc, but the background for displaying the title of this karaoke song,
It is also possible to record still image data with a background larger than the background displayed on the monitor TV screen and move the output in parallel on the screen to output as a moving image. As described above, various kinds of still image data can be recorded, but the present invention can be implemented regardless of the type of still image data.

Here, the background image disc No. 1 to N
o. Up to 4, the background image for the pop karaoke music is the background image disc No. 5 to No. 5 Up to 8, it is assumed that a common background image is continuously recorded such as image data which is a background image for an enka karaoke piece. In general, karaoke users who bring along prefer songs of the same system, and if it's pop, pop songs continue, and if it's enka, enka songs continue. In this case, it is also possible to switch and output the moving image data number of the same background image disc without replacing the disc and reproducing the still image data. As a result, the disc can be exchanged only for the karaoke music disc, which enables faster disc exchange.

Further, in the karaoke recording medium reproducing apparatus of the present invention, so-called frame advance reproduction is performed in which the switching of still images is switched at an arbitrary time interval until switching from still image data to moving image data. this is,
For example, there are various methods such as switching the still image data by the control unit 2 every one second, or switching each time the lyrics display unit of the karaoke music data is switched. It is also possible to give control information to the background image disk in order to give a visual effect and to instruct the control section 2 to perform special switching.

FIG. 3 shows a flowchart showing the operation of the karaoke recording medium reproducing apparatus according to the present invention. Step S1
Then, the starting step is shown. Step S2 is a step of initializing the karaoke recording medium reproducing apparatus. Performs initialization processing such as key control and machine parts inspection.

In step S3, it is a step of detecting whether or not an instruction to reproduce a karaoke piece has been issued from the operation input section 1. If there is no reproduction instruction, the process returns to step S3 to repeatedly confirm the reproduction instruction of the karaoke piece. Step S4 is a step of selecting the karaoke piece disc 8 in which the karaoke piece for which reproduction has been instructed is recorded from the disc changer section 3 and carrying it to the karaoke piece reproduction section 4.

In step S5, the background image disc 9 on which the background image suitable for the karaoke song selected in step S3 is recorded is selected from the disc changer unit 3 and is conveyed to the background image song reproducing unit 6. In S6, a karaoke piece and moving image data are reproduced. The first one of karaoke by this reproduction
It is a song to be sung.

In step S7, after the reproduction of the first karaoke piece is completed, the karaoke piece disc 8 in which the karaoke piece that has been sung so far is recorded is returned, and the karaoke piece disc from the disc changer unit 3 is reproduced in order to reproduce the next karaoke piece. 8 is the step of starting the transportation. Many karaoke songs are input from the operation input unit 1 and stored in a storage unit (not shown). In step S8,
This is a step of starting the reading of still image data from the background image disk 9 that has been used up to now to reproduce the next karaoke music piece into the background image memory unit 7. The still image data corresponds to the moving image data used in the next karaoke music, for example, moving image data No. If it is 15, the still image data No. 15 shall be selected.

In step S9, after the reading of the still image data is completed, the background image disk 9 recording the background image used in the karaoke music that has been sung so far is returned,
This is the step of starting the transportation of the background image disc 9 to be reproduced in the next karaoke piece. In step S10, the output of the still image data from the background image memory unit 7 is started. The background image is output until the reproduction of the next karaoke music starts.

In step S11, the karaoke music disc 8 on which the next karaoke music is recorded is placed on the karaoke music reproduction section 4 and the reproduction of the karaoke music disc 8 is started. Until the replacement of the background image disc 9 is completed, the background image is not a moving image but a still image or a frame-by-frame image of a still image. In step S12, the background image disc 9 on which the background image corresponding to the next karaoke song is recorded is placed on the background image reproducing section 6, and the reproduction of the background image disc 9 is started.

In step S13, a still image and a moving image are switched. The control unit 2 switches the output timing of the still image data and the moving image data recorded in the background image memory unit to match the output. After the switching is completed, the output of the moving image data is continued until one karaoke piece is sung. In step S14, it is a step of selecting whether or not to continue karaoke. If karaoke is to be continued, the next karaoke piece is input through the operation input unit 1, then jumps to step S7, and the same operation is performed thereafter. If a large number of karaoke songs have been previously input from the operation input unit 1 and stored in the storage unit, the process automatically jumps to step S7. If the karaoke is not continued, the process jumps to step S15.

In step S15, the ending step is shown. Even if the karaoke ends, the background image disc is still placed, and the background image, which is a still image, is provided to the next karaoke user.

In this flowchart, a still image is read every time a karaoke song is selected. However, the memory unit has a large capacity such as a hard disk, and it is also possible to record all the still image data in a batch at first and output the data by searching the control unit 2. In this case, step S8 can be omitted and the disc can be replaced more quickly.

As described above, according to the present invention, the still image data relating to all the moving image data of all the background image discs 9 and a part of the moving image data are used as one background image disc 9. Then, no matter which background image disc 9 is being reproduced, still image data corresponding to the next karaoke piece can be output to the memory section.

Further, since the still image data is a part of the moving image data, even if the output is switched from the still image data to the moving image data, the output can be switched without any discomfort.

Also, while the karaoke music disc 8 in which the karaoke music that has been sung so far is recorded is replaced with the karaoke music disc 8 in which the karaoke music to be sung next is recorded, the background image disc that has been used until now. Since the still image data based on the next karaoke music data from 9 is stored in the memory section, it is efficient in time, and since the background image disk 9 is replaced after the still image is output, the karaoke music disk 8 is replaced. Even if the karaoke music is played immediately after the end, the karaoke music can be sung immediately.
Also, when switching from still image data to moving image data after the replacement of the background video disc 9, the still image data and the moving image data are the same as the background image (for example, if it is a mountain, the background image of the same mountain is used). A person can switch the background image without feeling discomfort.

Further, until the still image data is switched to the moving image data, the still images are switched at time intervals, or so-called frame-by-frame reproduction is performed, so that the background image of the karaoke music is more natural. You can switch with and give a special visual effect.

[0044]

As described above, the time can be shortened in spite of exchanging two pieces of the first recording medium which is a karaoke music disc and the second recording medium which is a background image disc, and
Since two or more disks, which are image information recording media, can be used, it is possible to provide a fresh background image without limiting the image information.
