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.
Claims20
A system for synchronizing projected video content with a transparent display, comprising:
- a projector configured to receive video content and project the video content, wherein the video content has an associated audio content;
- a transparent display for receiving the projected video content and having one or more pixels capable of switching between a clear state and a hazy state;
- and
- a decoder for controlling the switching of the one or more pixels in the display between the clear and hazy states,
- wherein the decoder receives the audio content and decodes the audio content in order to synchronize the switching of the one or more pixels with the projected video content on the display such that the projected video content is projected onto one or more pixels in the hazy state.
A method for synchronizing projected video content with a transparent display, comprising:
- projecting video content to a transparent display, wherein the video content has an associated audio content;
- displaying the projected video content on the transparent display, wherein the transparent display has one or more pixels capable of switching between a clear state and a hazy state;
- and
- decoding the audio content in order to control the switching of the one or more pixels in the display between the clear and hazy states, comprising synchronizing the switching of the one or more pixels with the projected video content on the display such that the projected video content is projected onto one or more pixels in the hazy state.
A system for synchronizing projected video content with a transparent display, comprising:
- a projector configured to receive video content and project the video content, wherein the video content has an associated audio content;
- a transparent display for receiving the projected video content and having pixels capable of switching between a clear state and a hazy state;
- and
- a decoder for controlling the switching of the pixels in the display between the clear and hazy states,
- wherein the decoder receives the audio content and decodes the audio content in order to select a particular pixel pattern for the transparent display such that the pixels receiving the projected video content are in the hazy state and the pixels not receiving the projected video content are in the clear state.
