映像信号は、テレビジョン受像機（Ｂ）に入力される。Stereoscopic video disc has a field frequency of 1120Hz.
The video signals for the right eye and the left eye are recorded for each field. Therefore, the video reproducing means (1) reproduces and derives the identification switching signal together with the stereoscopic video signal. The front panel of the video disc player has
A first transmitting means is provided which blinks an infrared lamp in synchronization with the switching signal. Furthermore, the reproduced stereoscopic video signal is input to the television receiver (B).

、受像面に立体映像が映出される。On the other hand, the glasses (C) include a switching @ signal generating means (1) which emits a display mode switching signal No. 18, and a second sending means (8) having an infrared lamp that flashes based on this display mode switching signal.
), and when the user puts on the glasses (C) facing the television receiver (B), a second
The receiving means (6) detects the output of the second transmitting means (8), and the switching control circuit (4) switches the changeover switch (7) to the S side based on the detected output. As a result, the stereoscopic video signal is input as is to the video monitor means t61, and a stereoscopic video is projected on the receiving surface.

The shutters H are driven alternately. As a result, the image for the left eye is transmitted through the first shutter α, and the image for the right eye is transmitted through the second shutter.
They are each monitored via the shutter 03, making it possible to monitor stereoscopic images.

像信号が２回づつ連続導出される。When the user stores the glasses (C) without wearing them or removes the glasses (C) from the front of the television receiver (Bl), the second transmitting means (8) (mode switching signal 8) cannot be received by the second receiving means (4).As a result, the switching control circuit (4) switches the changeover switch (7) to M t
Switch to ltlJ. The image memory (3) to which the stereoscopic video signal is input samples and stores the stereoscopic video signal every other field and derives the same video signal twice. Therefore, the video signal for the right eye or the video signal for the left eye is continuously derived twice each to the video monitor means 16).
その結果、使用者は前記メガネ（Ｃ）を着用しないまま
モノラル映像をモニタすることが出来る。As a result, the user can monitor monaural images without wearing the glasses (C).
