Abstract

A method that enables multiple viewers to view one of several video streams simultaneously displayed on a single video display (or movie projection screen). Viewers can only view with shutter viewing glasses synchronized to the video stream they are viewing. This method also permits 3D viewing without modification of the video broadcast, video receiver technologies and minimal adaptation of existing 2D camera equipment. This method can also limit viewing access to permitted granted viewers only in the presence of non-granted viewers for security or privacy by encrypting the frame rate and generating masking video.

Claims

1. What I claim as my invention is a method that permits the viewing of one of several video streams being simultaneously displayed on a single display using shutter glasses synchronized with the particular viewed video stream, that can also be operated in 3d mode to combine two left-right video streams from two separate broadcast channels to create a 3d illusion without in anyway degrading the existing 2d broadcast viewing:

What I claim as my invention is a method of video display that limits decoded interpretable viewing to permitted viewers wearing shutter glasses synchronized to a decrypted frame rate so that unauthorized viewers not wearing synchronized glasses are prevent from decoding the video and interpreting viewing by the injection of masking video into the unsynchronized frames and encrypted variations in the synchronized frame rate.
