FIG. 2 shows an example of a conventional AV device. In Figure 2,
The input source device 100 is an FM/AM tuner, T
V/BS tuner, compact cassette deck, digital audio tape (DAT) deck, video tape recorder (VTR), laser vision disc (LD)
) player included. A compact disc (CD) player 103 is also included.

Among these input source devices 100, devices that output video signals together with audio signals include TV/BS tuners, VTRs, and LD players, and CD players can output still images using subcodes and the like. On the other hand, the input source device 100 that outputs only audio signals is an FM/
These are AM tuners, compact cassette decks, and CD players, but in order to diversify the system, the graphic processor 101 is used to display various information such as acoustic characteristics, audio control function display, graphic equalizer function display, etc. from the CRT monitor screen. It is now displayed. 108 is a remote control device.

During playback, the audio input source device 100
is used, the audio signal is sent to the main amplifier 105 under the overall control of the system controller 107.
In addition to outputting the desired image via the subica 106, the graphic processor 101 outputs the desired image to the monitor TV1.

When a video-type human-powered source device 100 is used, images included in the input source are displayed on the monitor TV 102 by the graphic processor 101 under the control of the system controller 107, and audio signals are also sent to the main amplifier 105 and speaker 106. output via

On the other hand, in recent years, so-called multi-CD players have been introduced that allow multiple CDs to be stored in one magazine and playback audio from each magazine in order to facilitate the handling of CDs and enable long-term continuous playback. It is widespread. In that case, the CD changer 10 is used to automatically change CDs.
4 is used.

[Problem to be solved by the invention]

By the way, in recent years there has been a so-called karaoke boom,
I have not yet seen any of the above AV devices equipped with a karaoke system. Karaoke systems using LD players are designed to display a combination of lyrics and videos, but CDs are similarly blasphemous as optical discs.
In this case, it is possible to display still images using subcodes.

CDs are superior in terms of ease of handling. Especially when considering in-vehicle karaoke systems such as tourist buses,
A CD karaoke system is appropriate for making effective use of limited space.

Therefore, the present invention combines an AV device with an information reproducing device such as a CD karaoke system containing still images, and provides an information reproducing device that can automatically operate the CD karaoke system when the CD is loaded. The purpose is to

[Means to solve the problem]

In order to solve the above problems, the present invention provides an information reproducing apparatus including an audio reproduction system, a video reproduction system, and an audio reproduction system for reproducing audio signals and video signals recorded on a digital recording medium. includes a still image signal, and outputs an identification signal; a video output selection circuit that outputs the still image signal to the video reproduction system based on the identification signal; The present invention is characterized in that it includes a mixing circuit that mixes audio signals from a microphone into the sound reproduction system.

[Effect]

According to the present invention, the identification circuit identifies whether or not the digital medium includes a still image signal, and outputs an identification signal. Based on this identification signal, the output selection circuit outputs the still image signal to the video reproduction system in the information reproduction device. Therefore, the still image signal in the digital recording medium is displayed.

On the other hand, the identification signal causes the audio signal from the microphone to be mixed into the sound reproduction system in the information reproduction device via the mixing circuit. Therefore, the audio signal is mixed with the audio signal originally included in the digital medium and output.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an embodiment of the present invention. In this Figure 1,
The same reference numerals are given to the parts that overlap with those in FIG. 2, and detailed explanation thereof will be omitted.

In FIG. 1, the difference from FIG. 2 is that the video playback system includes a subcode decoder 1 that decodes the subcode (QW signal) in the CD output from the CD changer 104, and a subcode decoder 1 that decodes the subcode (QW signal) in the CD output from the CD changer 104, and This part is equipped with a selector 5 that switches either the still image signal 2 or the normal video signal 3 from the graphic processor 101 in accordance with the video selection signal 4 from the subcode decoder 1. Also,
In the sound reproduction system, a handset device 8 having a small-screen hand monitor device 6 and a microphone 7;
A preamplifier 10 amplifies the microphone output signal (hereinafter referred to as a microphone signal) 9, and a CD playing signal 11 from the amplified microphone signal 9 and a CD changer 104.
This part includes a mixer 12 that mixes the signals and outputs the mixed signal 11 to the main amplifier 105.

The handset device Wl8 has a hand monitor device 6 and a microphone 7 housed in a handheld casing, and is held by a person singing karaoke and uses the microphone 7 while looking at the lyrics displayed on the hand monitor device 6. This allows voice input. The hand monitor device 6 is configured using a small CRT display, a liquid crystal display, or the like, and signals are distributed so as to display the same screen as the content displayed on the monitor TV 102. It is convenient if the microphone 7 is extendable and retractable so that it can be adjusted to approach the mouth as necessary.

Next, the operation will be explained.

In FIG. 1, for example, BGM music is being played from a human source device 100 such as a tape deck, and at this time, a graphic equalizer function display is displayed by the graphic processor 101 on the screen of the monitor TV 102 via the selector 5. It is assumed that there is

If you operate the CD player 103 to perform karaoke, if there are still images on the CD, the C
Subcode 13 is output from D changer 104.

Then, the subcode decoder 1 decodes the subcode 13 and outputs the video selection signal 4. This is equivalent to identifying that a still image is included in the CD. The video selection signal 4 is sent to the selector 5, and the selector 5 is switched from the normal video signal 3 side to the CD still image signal 2 side. Therefore, the monitor TV 102 has a subcode decoder 1.
A still image is displayed. This one still image is also displayed on the hand monitor device 6 of the handset device 8 at the same time. On the other hand, the CD accompaniment signal 11 in the CD is transmitted to the CD changer 1.
04 to the mixer 12, via the main amplifier 105 and output from the subwoofer 106, the singer can sing while looking at the nearby hand monitor device 6, and the microphone signal 9 from the microphone 7 can be sent to the pre-amplifier 10.
The signal is sent through the mixer 12, where it is mixed with the CD('P performance signal 11) and output from the speaker 106.

When there is no still image output from the CD, subcode decoder 1
Since the subcode 13 is not received, the video selection signal 4 is stopped. Then, selector 5 automatically selects normal video signal 3.
Switch the input to the side and return to the original state.

Thereafter, similarly, when a CD with still images is played, the selector 5 is automatically switched by the video selection signal 4, and karaoke becomes possible.

〔Effect of the invention〕

As described above, according to the present invention, it is determined whether or not the attached digital recording medium includes a video signal such as a still image, and the video is automatically switched to be displayed and output. It becomes possible to automatically temporarily interrupt the content currently displayed on the screen and display the content from the digital recording medium.
