Abstract

PURPOSE:To reproduce the signal of a compact disk (CD) in plural terminal video devices by reproducing and displaying the picture-recorded and sound- recorded contents of an IC memory from the head of the contents through a reading port to the terminal video device asynchronously with the other terminal video device according to the reading request of the terminal video device. CONSTITUTION:An asynchronous reproducing controller 2 is equipped with an IC memory 21 which is connected to a CD player 1, a reading port 22 to be connected to the IC memory 21 and a port driving device 23 which is connected to the reading port 22. A terminal video device 3 is equipped with a color CRT 31, which is connected to the reading port 22, and a reading request switch 32 to be connected to the port driving device 23. Since these reading request switches 32 are independent, a picture is reproduced to the respective color CRTs 31 from the head of the picture asynchronously with the other color CRTs 31 according to the different of timing, with which the reading request switches 32 are turned on. Thus, guide information can be arbitrarily observed on the guide screen of the respective terminals 3 from the head of the information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording/playback system, and more particularly to a compact disc asynchronous playback system in which signals recorded on a compact disc are played back to a plurality of terminal video devices.

[Conventional technology]

Conventionally, - compact discs (hereinafter referred to as CDs)
To play back asynchronously on multiple playback devices (terminal video devices), connect a CD player to each terminal video device,
Each CD player plays the same type of CD.

[Problems to be Solved by the Invention] In the conventional CD asynchronous playback method described above, in order to asynchronously play back the contents of one type of CD on multiple playback devices, it is necessary to connect a CD player to each playback device and play back the same type of CD. C of
The disadvantage is that the CD must be played back on each CD player.

An object of the present invention is to provide a CD asynchronous playback system that economically realizes such asynchronous playback of CDs.

[Means to solve the problem]

The CD asynchronous playback system of the present invention includes an IC memory connected to a compact disc player and storing recorded contents of the compact disc, a plurality of read ports connected to the IC memory, and a plurality of read ports connected to the read ports, respectively. a compact disc asynchronous playback control device having a port drive device; and a plurality of terminal video devices each having a color CRT and a read request switch connected to the read port and port drive device respectively,
When activated from a read request switch of the terminal video device, the recorded content of the IC memory is played back and displayed on the terminal video device from the beginning via the read port, asynchronously with other terminal video devices. Ru.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram of a CD asynchronous playback system for explaining one embodiment of the present invention.

As shown in FIG. 1, this embodiment has a CD player 1 and a CD player.
It is composed of an asynchronous playback control device 2 and a terminal video device 3. This asynchronous playback control device 2 includes an IC memory 21 that is connected to the CD player 1 and stores the recorded contents of the CD.
and a plurality of read ports 22 connected to the IC memory 21
and a plurality of port drive devices 23 connected to the readout port 22, and the terminal video device 3 is connected to the readout port 22.
Color CRT 31 and port drive device 23 connected to 2
A read request switch 32 is connected to the read request switch 32. The reproduced output signal from the CD player 1 is first read into the IC memory 21.

The video and audio signals read into the IC memory 21 are read out to the terminal side by turning on the continuation request switch 32 on the terminal side. That is, the read request switch 3
The port drive device 23 connected to read port 2
2, the data is sent to the color CRT 31 and reproduced.

In short, a plurality of read ports 22 are connected to the IC memory 21 of the CD asynchronous playback control device 2 described above, and each read port 22 has a CRT 31. The port driving device 23 and the read request switch 32 are connected to the same thread. Since each of these read request switches 32 is independent, the image is reproduced from the beginning on each color CRT 31 asynchronously with the other color CRTs 31 due to the difference in the timing at which the successive request switch 32 is turned on.

〔Effect of the invention〕

As explained above, the CD asynchronous playback method of the present invention is
- Images can be played back asynchronously on multiple screens by storing them in the IC memory of the playback control device based on one CD and one CD player and accessing them asynchronously from the readout port corresponding to each terminal device. becomes possible. This allows multiple customers to press the guidance request switch at any time on the guidance screen of each terminal installed in the facility, by recording guidance from many locations and within the facility onto a single CD. The advantage is that you can view the guide information from the beginning by just clicking the button.
