2. Description of the Related Art Conventionally, a karaoke reproducing apparatus (that is, an accompaniment sound of a song is reproduced and a sound input from a microphone is mixed by using a compact digital data recording disk having a diameter of about 12 cm, which is called a CD (compact disk). Various devices are being developed. In this case, in the case of what is usually called a CD, only a maximum of about 74 minutes of audio data is recorded as main digital data on one disc, but in a karaoke reproducing device, images such as lyrics are reproduced. It is more convenient to display it according to the voice. Therefore, the CD used for karaoke
In some cases, there is an additional recording area called a subcode in which video data of a still image for displaying lyrics is recorded.

On the other hand, since a moving image can display a more complicated image than a still image, a video recording disc using a relatively large disc (for example, a diameter of about 30 cm) called a video disc was used. Various karaoke playback devices have been put to practical use. However, since the video disc has a large diameter, it has a large storage space and has a disadvantage that it can be used only when the karaoke device has a sufficient installation space.

In order to solve these inconveniences, ISO
A coding system called MPEG1 system standardized by (International Organization for Standardization) was applied to develop a compact disc capable of recording long-time audio data and moving image data. In recording by this method, sub-band division, bit allocation for each divided band, etc. are performed, digital audio data is compressed to a fraction (for example, 1/5) and recorded, and this audio data and time division are used. , DCT or the like is used to record digital moving image data highly efficient compressed to several tens to several hundreds, for example, a CD.
When applied to a (digital data recording disk called CD-ROM), about 74 minutes of digital audio data and moving picture digital video data can be recorded on one disk.

However, the monitor receiver dedicated to the reservation display may be prepared if necessary.

Next, with reference to the flow chart of FIG. 3, the operation when reproducing is performed using the reproducing system configured as described above will be described.

First, the system controller 21 determines whether or not there is a song reserved for reproduction (step 1
01) If there is no reserved song, a display screen showing that the reservation is accepted is created by the control of the second central control unit 41 and is output from the NTSC processing circuit 45, and at the same time the changeover switch 30 is operated. The movable contact 35 is connected to the second fixed contact 32, and this reservation acceptance screen is displayed on the monitor receiver 52 (step 102).

As the reservation acceptance screen displayed at this time, for example, as shown in FIG. 4, a reserved music display area for nine music pieces is set, and the reservation operation for inputting the music number is performed, and the number thereof is changed. The data of the music title corresponding to is searched for from the storage data of the ROM 42 and the RAM 43, and the music number and the music title are displayed in order from the top. In FIG. 4, only one song is input, and here, the song number display "2-6" indicating that it is the sixth song of the disc number 2 and the song name "Green Horizon" are the display areas of the first song. Is displayed in. In this case, at the same time as the reservation song display, "Please make a reservation" is displayed as a display prompting the reservation operation.

When the reservation acceptance screen is displayed, the system controller 21 returns to step 101 to determine whether there is a reserved song. Then, if there is a reserved song, it is judged whether or not the reserved song is in a standby state in which it can be reproduced (step 103).
In other words, in the system of this example, when a song is reserved, the system controller 21 controls the disc on which the reserved song is recorded to be loaded into any of the disc playback units 12 and the loaded disc. Perform a search operation to search for the recording location of the corresponding song from. And step 1
In 03, it is judged whether or not the search operation of the music to be reproduced next is completed. When the search operation is not completed, a display screen indicating that the search is being performed is displayed on the second central control unit. Created under control of 41, NTSC processing circuit 4
5 is output (step 104). At this time, the movable contact 35 of the changeover switch 30 maintains the state of being connected to the second fixed contact 32, and causes the monitor receiver 52 to display the screen being searched.

When it is determined in step 106 that the start key has been operated, the system controller 21 starts the reproduction of the corresponding music piece of the disk 11 loaded in the disk reproduction section 12, and the reproduction data of this music piece is reproduced. Reproduction processing is performed under the control of the first central control unit 29, and audio signals obtained by reproduction are outputted from the output terminals 6L, 6R and reproduced by the speakers 51L, 51R, and at the same time, of a moving image obtained by reproduction. The video signal is output from the NTSC processing circuit 27. Then, at this time, the movable contact 35 of the changeover switch 30 is switched to the first fixed contact 31, and the video of the moving image reproduced from the disk 11 is displayed on the screen of the monitor receiver 52 connected to the output terminal 7 ( Step 107).

While the audio and video are reproduced from this disc, the system controller 21
Then, it is determined whether or not the redo key of the operation keys 1 is operated (step 108). When it is determined that the redo key has been operated, a display screen for instructing to re-input a song to be played back is created by the control of the second central control unit 41, and is output from the NTSC processing circuit 45. (Step 109). At this time, the changeover switch 3
The 0 movable contact 35 is switched to the second fixed contact 32, and the monitor receiver 52 displays a screen for instructing this re-input.

As the screen for instructing re-input displayed at this time, for example, as shown in FIG. 7, the reserved tune display screen and the reserved tune display up to 9 tunes similar to the screen during the search are displayed and re-input is performed. As a display for instructing, "Please input again" is displayed. However, in the display in this case, the second display area from the top is the display of the first reserved music (that is, the leftmost number is 1, 2, 3, ... From the second display area), The reserved song display area displayed in is the display area for the song to be re-input, and the song that has been played once is displayed until the re-input is performed.

In this state, when the music number is input by the operation key 1, the music title displayed at the top is changed to the music of the newly input number, and step 10
Returning to step 6, it is judged whether or not the start key has been operated. By operating the start key, step 107
Move to and play the newly input song.

In some cases, the same song may be reproduced again from the beginning without changing the song number. In such a case, operate the Redo key to display the screen for instructing re-input, and do not input a new song number. It will be played again from the beginning.

Then, the system controller 21 determines whether or not the music has been reproduced to the end (step 1
10) If it has been played to the end, return to step 101, judge whether there is a next reserved song, and display the corresponding reserved screen until the start key is operated (FIGS. 4 to 6).
Either).
