20100290126 | Multiple Imaging Arrangements for Head Mounted Displays - A head mounted display is disclosed that utilizes a single video display screen to transport images to both eyes. Multiple reflections are created by illuminating the display screen form a plurality of directions, or by illuminating the display screen with light beams of differing polarizations. The reflections of the display screen are focused in order to reduce the splitting volume and then redirected by a plurality of reflective surfaces located near the focal point of the display images. Different images may be sent to each eye of a user by interlacing multiple data streams for the display and linking each data stream with a specific illumination direction, or specific polarization. | 11-18-2010 |
20100208830 | Video Decoder - The present invention is directed to a system and method which allows highly compressed data files to be expanded in a standalone decoder having an output at least 80 times larger than the compressed input. In one embodiment, a universally available interface is used to transport encoded media from a host PC to a decoder external to the PC for expansion and presentation as a HD display image. In one embodiment, a USB port of the user's PC (or other storage device) is used to transport data at a rate of between 0.3 Mbit/sec and 5 Mbits/sec for expansion into a robust HD signal of up to about 3Gbits/sec or higher. In other embodiments, provision is made for reducing the decompressed expanded data file to below 480 Mbits/sec so as to accommodate retransport of the decompressed file back to the PC or storage device for temporary storage or display. | 08-19-2010 |
20100014596 | SYSTEMS AND METHODS FOR IMPROVING THE QUALITY OF COMPRESSED VIDEO SIGNALS BY SMOOTHING BLOCK ARTIFACTS - The present invention is directed to systems and methods in which, for a given amount of data required to represent a compressed video signal, the quality of the uncompressed displayed real-time video, as perceived by a typical human viewer, is improved. Systems and methods herein achieve this improvement by attenuating the appearance of blocks without necessarily having a priori knowledge of their locations. The methods described herein attenuate the appearance of these blocks such that the quality of the resultant real-time video, as perceived by the HVS, is improved. | 01-21-2010 |
20100014578 | SYSTEMS AND METHODS FOR HIGHLY EFFICIENT VIDEO COMPRESSION USING SELECTIVE RETENTION OF RELEVANT VISUAL DETAIL - Systems and methods are presented for compressing digital video signals in a manner that prevents the creation of block artifacts and improves compression efficiency by the selective removal of data representing visually imperceptible or irrelevant detail. Bandwidth control is improved through prioritized removal of data exceeding permissible bandwidth limits. This provides a process by which a coupled compressor and de-compressor system can effect the transmission or storage of video at low bitrates with high perceptual quality of the decompressed video. In one embodiment, the low frequency components are removed from a video stream and either stored or transmitted in compressed format separate from the storage or transmission of the high frequency components of the video stream. Certain high frequency video stream details can be suppressed to further reduce bitrate. | 01-21-2010 |
20090158501 | DISPLAY DEVICE SUPPORT SYSTEM - A system for supporting video display devices in front of a user. Support system includes a headwear element that is placed over or upon a user's head. A display device, such as a three-dimensional display device is placed in an adjustable support structure that is located at the front of the headwear element. Through the adjustable structure the display device can be positioned at the best level for the user's eyes. In some embodiments the headwear element can use a support strap provided towards the rear of the headwear element to helps support the weight of the display device. | 06-25-2009 |
