Abstract
Synchronizing video content projected onto a transparent display with switching of pixels in the display. The transparent display has pixels capable of switching between a clear state to make portions of the display transparent and a hazy state to display the projected video. A decoder receives and decodes audio content associated with the video content in order to control the switching of the pixels in the display such that the video content is projected onto pixels in the hazy state.
