And the disc player 2 for the left eye are connected by a communication line 5 and a synchronizing signal line 7 capable of bidirectional communication.

The disk controller 1 is capable of controlling the operation of the left-eye disk player 2 and reading the operating state of the disk via the communication line 5, and further, when reproducing the left-eye disk player 2. The video signal is output from the video signal line 8 in synchronization with the synchronization signal output via the synchronization signal line 7.

The disc player controller 1 and the right-eye disc player 3 are connected by a communication line 6 and a synchronizing signal line 7 capable of two-way communication, and are synchronized in the same manner as the left-eye disc player 2 described above. A video signal is output from the video signal line 9 in synchronization with the signal.

The stereoscopic monitor 4 is connected to the left-eye disc player 2 via a video signal line 8 and connected to the right-eye disc player 3 via a video signal line 9.
Video signals from the respective disc players 2 and 3 are supplied to the stereoscopic monitor 4. The stereoscopic monitor 4 has a screen using a lenticular lens, and the left-eye video signal from the video signal line 8 is provided only to the left eye of the observer, and the right-eye video signal from the video signal line 9 is provided to the observer. Operate so that only the right eye can watch.

Note that the stereoscopic monitor 4 can use a system with glasses using polarized glasses or liquid crystal shutter glasses.

In the system configured as described above, the left and right eye images related to the stereoscopic monitor 4 are displayed as shown in FIG. 2 so that each disk player can be controlled by the same synchronization signal. The left-eye video and the right-eye video are recorded at the same disk frame position in the disk medium.

Next, the disc player controller 1
In order for the left-eye disc player 2 and the right-eye disc player 3 to reproduce the same video frame in synchronization,
At the time of reproduction, control is performed as shown in the flowchart of FIG.

In FIG. 3, first, the disk frame number currently being reproduced is read from the left-eye disk player 2 being reproduced via the communication line 5 (step 31).

Next, the number of the currently reproduced disk frame is read from the currently reproduced right-eye disk player 3 via the communication line 6 (step 32).

Then, the disc frame numbers are compared (step 33), and if they match, the reproduction is continued as it is.

If they do not match, the disc player 2 for the left eye and the disc player 3 for the right eye transmit control signals via the communication lines 5 and 6 so as to form the same disc frame. , And is supplied to the right-eye disk player 3 to correct the disk frame (step 34), and the reproduction is continued.

This process is performed within one clock of the synchronization signal.

It is output to the control microcomputer 41 via the operation key input circuit 48.

Also, in this embodiment, two types of discs recorded in different formats (a disc in which related left and right eye pictures are recorded in the same disc frame number) and a disc in which related left and right eye pictures have different disc frame numbers The disc player controller 1 is provided with two types of operation modes for reproducing the disc recorded on the disc.

That is, one is a mode (hereinafter referred to as mode 1) in which the left-eye disc player 2 and the right-eye disc player 3 are reproduced and controlled by the same disc frame, and the other is a left-eye disc player. This is a mode (hereinafter referred to as mode 2) in which the difference between the recording start disk frames of the disc player 2 and the right-eye disc player 3 is read, and reproduction control is performed while maintaining the difference.

When reproducing in mode 2, if there is no difference between the frames read from each of the disc players 2 and 3, the reproduction is stopped.

Further, as shown in FIG. 5, a disc in which related left and right eye images are recorded at different disc frame numbers is different from a right eye video frame of a right eye disc medium with a left eye disc medium of a left eye disc medium. It is assumed that an ophthalmic video frame is recorded in a format shifted by 100 frames.

The switching operation between the two modes is as follows.
When the disc player is stopped, the two keys are toggled by continuously pressing the send key and the return key of the operation keys within two seconds. The contents of the change are managed by the mode changing means 41b. Have been.

FIG. 5 shows a disc player controller 1.
As shown by, the left-eye disk medium and the right-eye disk medium having a predetermined frame difference (100 frames) in the related disk frames are synchronized with the related left-eye image and right-eye image. The control of the disc player is performed according to the flowcharts of FIGS. 6 and 7 so as to reproduce the data.

FIG. 6 is a flowchart for exchanging a disc recorded in a different format, and FIG. 7 is a flowchart for reproducing a disc recorded in a different format.

In FIG. 6, the mode is changed at the time of initialization or at the time of disc medium exchange.

First, the chapter 1 is searched (the head is moved) with respect to the disc player 2 for the left eye via the communication line 5, and the disc frame number is read (step 61).

Next, the chapter 1 is searched for the disc player 3 for the right eye via the communication line 6 and its disc frame number is read (step 62).

Then, the difference between the two disk frame numbers (in this case, 100 frames) is recorded in the CPU as the basic disk frame difference (step 63).

Thus, the mode of the disc player controller 1 is changed.

In FIG. 7, first, the disc frame number currently being reproduced is read from the disc player 2 for the left eye via the communication line 5. (Step 71) Next,
The currently playing disc frame number is read from the right-eye disc player 3 via the communication line 6 (step 72), and both disc frame numbers are compared (step 7).
3) If both disc frame numbers do not match, the process proceeds to step 74, and if both disc frame numbers match, the process proceeds to step 77.

Then, it is determined whether or not the mode is the mode 1 (step 77). If the mode is the mode 1, the reproduction is continued. If the mode is the mode 2, the left-eye disc player 2 and the right-eye disc player are performed. In order to stop reproduction of the disc player 2, the stop data is transmitted via the communication lines 5, 6 to the respective disc players 2, 3
Output to

Next, the disc frames read from the disc players 2 and 3 are compared (step 73).
If it is determined that the comparison outputs do not match and the mode is Mode 1 (Step 74), the same disk frame correction as in the related art is performed (Step 76).

On the other hand, if the mode is determined to be mode 2, the difference between each disk frame and the basic disk frame difference (100 frames) are compared (step 75), and the frame difference between each disk frame matches the basic disk frame difference. If so, the reproduction is continued, and if they do not match, the disc frame is corrected so as to be the basic disc frame difference (step 78), and the reproduction is continued.

The process shown in FIG. 7 is performed within one clock of the synchronization signal.

In this way, it is possible to reproduce the disk media recorded in different formats.

[0052]

According to the present invention, even if the left-eye disk medium and the right-eye disk medium as the video sources of the stereoscopic video are not recorded in the same disk frame number, the related video frames are synchronized. Can be reproduced, and an optimal stereoscopic video display can be realized.
