Abstract: A secure digital data distribution system (100) for preventing unauthorized access to digital data. The system utilizes an identification system module (116) embedded in a digital storage media (114) to grant authorization to media players (118). Prior to reading the digital data recorded on the media (114), an identification system interrogator (122) reads authorization data from the identification system module (116) to determine whether the media player (118) is authorized to read the media (114). If the authorization data matches the media player's unique identifier, authorization is granted and the media player (118) commences to read the media (114).

Abstract: A method and system for communicating and rendering stereoscopic or dual-view images are provided. In one embodiment, a method rendering stereoscopic images includes alternating, on a display, left and right perspectives of an image. Each of the left and right perspectives corresponds to a respective array of pixels on the display such that the left perspective is offset from a right perspective by less than a pixel width. The method further includes shuttering a portion of the light provided from the display in sequence with the alternating of the left and right perspectives if the image.

Abstract: A display system (200) in which light from source (202) is focused onto a spinning color wheel (204). The spinning color wheel (204) spins at a constant rate and creates of beam of light that changes from one primary color to the next in rapid sequence. The primary colored beam of light impinges a spatial light modulator (206), which is often a DMD or LCD. A controller (208) receives an input video signal and determines the native frame rate of the image source. The controller (208) sends image data to the spatial light modulator (206) in synchronization with the color wheel (204)—image data representing the red portions of the image is sent during the period in which the red color filter is passing through the beam of light—at the native frame rate of the image source. The modulated light is focused onto an image plane (210) by projection lens (212) to form an image. The eye of the viewer integrates the sequential primary color images giving the perception of a single full-color image.

Abstract: An integrating rod (100) for combining light beams from two or more sources. A first light beam (104) enters the integrating rod 100 through a first entrance face (102) to a first reflecting face (110). The light is reflected by the first reflecting face (110) and travels along the major axis (114) of the integrating rod (100) to an exit face (116). A second light beam (108) from a second light source enters the integrating rod (100) through a second entrance face (106). The second light beam may be reflected by a second reflecting face (112) and travels along the major axis (114) to the exit face (116). The two light beams experience multiple reflections as they travel along the integrating rod and leave the integrating rod (100) through the exit face (116) as a single homogenous light beam.

Abstract: Methods of controlling the illumination source (18) of an SLM-based display system (10). It is assumed that the system (10) displays pixel data formatted into a bit-plane format so that all bits of the same bit-weight can be displayed simultaneously. To provide greyscale, the amplitude of the source (18) may be modulated so that bit-planes having greater bit-weights are displayed with more intense illumination than bit-planes having smaller bit-weights (FIGS. 2 and 3). To avoid visual artifacts, the duty cycle of the bit-plane display times may be shortened relative to the frame period. (FIG. 4A). The latter method can be accompanied by a shortening of the duty time of the illumination on SLM (15). (FIG. 4B). The short duty cycle method may be used together with illumination amplitude modulation, or it may be used with the PWM method of providing greyscale.
