Abstract
A stereoscopic display system unambiguously tags the perspective view for left and right video fields by encoding at least one of the video fields with a unique code, then detecting the code in order to drive shuttered eyewear in synchrony therewith.

12. An electronic stereoscopic display system, comprising:
-
video source means for generating a video signal, said video signal including left and right video fields each having a plurality of lines therein, wherein at least one of the video fields is encoded with a first video code on a predetermined line of the video field; display means for receiving and displaying the video signal; eyewear for viewing the display means; interface means for coupling the video source means to the display means, said interface means being adapted to monitor the video signals, to detect the first video code, and to generate a shutter enable flag upon detection of the first video code; and controller means coupled to the interface means for generating and transmitting a shutter enable signal to the eyewear after receiving the shutter enable flag; wherein said eyewear includes left and right electrooptical shutters therein responsive to the controller means. - View Dependent Claims (13, 14, 15, 16)

19. A method for electronically identifying the perspective of left and right images in a stereoscopic video signal, wherein the video signal is reproduced on a video display screen and a user observes the video display screen through a field selection device having left and right electrooptical shutters therein, comprising:
-
encoding a specific location of each image with a video code, wherein the left images are encoded with a first video code and the right images are encoded with a second video code, monitoring the video signal using circuit means adapted to detect at least the first and second video codes, and enabling the left electrooptical shutter when the first video code is detected and enabling the right electrooptical shutter when the second video code is detected. - View Dependent Claims (20, 21)
