Latest Patents

One of Holtzman's latest patents is for a bi-directional screen. This innovative screen alternately switches between a display mode, which shows conventional graphics, and a capture mode, where the LCD backlight is disabled. In this mode, the LCD displays a pinhole array or a tiled-broadband code. A large-format image sensor is positioned behind the liquid crystal layer, allowing the image sensor and LCD to function as a mask-based light field camera. This setup captures an array of images equivalent to that produced by multiple cameras spanning the display surface. The recovered multi-view orthographic imagery is utilized to passively estimate the depth of scene points from focus.

Another significant patent is for a system and method for a multicast video-on-demand delivery system. This system divides video files into sequentially organized data segments for transmission and playback. Each segment is transmitted repeatedly in a looping fashion over a transmission channel. The transmission rate is equal to or greater than the playback rate, and the lengths of the segments are carefully chosen to ensure efficient channel tuning and data reception. The segments are presented sequentially, even as new segments are being downloaded, optimizing the viewing experience.
