Abstract
A method of operation of three dimensional (3D) stereoscopic television consistent with certain implementations involves turning on or installing a set of 3D glasses on a viewer to cause the set of 3D glasses to enter an active operational mode; and at the 3D glasses, emitting a signal to the television that causes the television to switch from a 2D display mode to a 3D display mode. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
