Further, the recording information of the disk 2 is read and sound is emitted from the speaker 11, and the hard disk information is read and an image is displayed on the screen 14 a of the monitor 14.

  Next, the operation of the disc player will be described with reference to the drawings.

  Here, a case where the SACD is played back by the disc player 1 will be described.

  In this SACD, pops are recorded as described above, and pop names, singer names, recording times, etc. are printed on the surface and cover of the disc.

  In addition, voice information of pops is recorded in the SACD user data area, and character information of the pops name and singer name is also recorded in the text information area.

  The user prepares in advance to enjoy watching the video while listening to this pop. For example, when the user creates a slide show in which the photos of the singer are collected, a scanner is used when using the photos printed on paper.

First, after connecting a scanner to the USB terminal 18, the singer's photographs are sequentially read by the scanner.
Then, this scanner is operated to output video information. At this time, the necessary number of images may be taken in according to the pop recording time.
When this video information is sent to the disc player 1, the control unit 20 drives the HDD 19 to sequentially store it in a predetermined area of the hard disk.

  Thereafter, the user registers an image so that the SACD audio information and the hard disk video information are linked.

  When the menu key of the remote controller 16 is operated, menu items such as initialization, setting and registration are displayed on the screen 14a of the monitor 14 as shown in FIG.

  Here, when registration is selected, a genre and a singer are displayed on the screen 14a as shown in FIG. When the user selects a genre, genres such as pop, classic, rock, and enka are displayed as shown in FIG.

When pops are selected in this genre, pops character information is registered in the hard disk.
At this time, the control unit 20 stores pop character information in association with the video information address.
As a result, when text information indicating pops is transmitted during SACD playback, video information corresponding to pops character information can be read from the hard disk.
If the SACD records the singer's name along with the genre, the singer's name may be input instead of the above-mentioned pop.
In this case, when a singer is selected on the registration screen shown in FIG. 3, the control unit 20 displays a guide character or a blank prompting the user to input the singer name as shown in FIG.
Here, when the user operates the remote controller 16 to input the singer name and press the enter key, the character information of the singer name is transmitted.

The control unit 20 receives this and associates it with the address of the video information and stores it in the hard disk.
Thereby, when the character information of the singer name is transmitted during the SACD reproduction, the video information corresponding to the singer name can be read from the hard disk.

  By the way, if the photograph to be used is taken with a digital camera, the digital camera is connected to the USB terminal 18, and this is operated to output video information.

  Upon receiving this video information, the control unit 20 stores it in a predetermined area of the hard disk. Therefore, it can be used for a slide show, similar to the above-mentioned printed photo.

In addition, if the user wants to enjoy watching a moving image while listening to music, it is only necessary to capture video captured by a video camera.
In this case, a video camera is connected to the USB terminal 18, and this is operated to output video information. Upon receiving this video information, the control unit 20 stores it in a predetermined area of the hard disk.
Also at this time, the necessary time is taken in accordance with the recording time of the pops. Then, as described above, registration is performed by genre or singer name.

  Next, when performing SACD playback, this SACD is set in a tray.

  When the user operates the play key of the remote controller 16, the control unit 20 starts the reproduction operation.

  When the SACD information is read by the optical pickup 4, it is sent to the signal processing unit 7. The signal processing unit 7 extracts text information from the read information of the lead-in area and transmits it to the control unit 20 side.

Further, the signal processing unit 7 discriminates an audio signal from the SACD to be subsequently input, and sends the output signal to the SACD reproducing unit 9. The SACD reproducing unit 9 decodes the audio signal and sends it to the audio signal output unit 10.
The audio signal output unit 10 emits an audio signal to the speaker 11 side to emit pop music.
On the other hand, the control unit 20 that has received the text information discriminates character information from the text information. At this time, the character information is sequentially compared with the genre information stored in advance in the memory.
If it is found that the character information is pops, the HDD 19 is driven to read video information corresponding to pops from the hard disk.

  Then, the video information is sent to the video signal output unit 12, and the video of the photograph is sequentially displayed on the screen 14a of the monitor 14. This photographic video continues to be displayed on the screen 14a while pop music is emitted from the speaker 11, so that it becomes a singer slide show.

This allows the user to view the singer's slide show while listening to pops.
If the singer name is registered in advance instead of the genre information as described above, text information indicating the singer name is sent to the control unit 20.

Since the control unit 20 reads the video information corresponding to the singer name from the hard disk, the singer slide show is displayed on the screen 14a while the pop is being emitted as described above.
In addition, by storing a scene captured by a video camera in a hard disk, moving image information can be read out by genre or singer name during SACD playback, and the scene can be displayed on the screen 14a.

  Therefore, the user can listen to pops while viewing the scene with a moving image.

By the way, when an imaging scene of a video camera is used, an image may be directly displayed without being stored in the hard disk.
In this case, a video camera is connected to the USB terminal 18, and this is operated to output video information. At this time, the reproduction of the video information is synchronized with the reproduction of the audio information.
Then, a scene is projected as a moving image on the screen 14a while pops are being emitted. Therefore, the user can always enjoy watching a new captured image, not a one-pattern image, while listening to music.

  The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.
