摘要： A video processing method and system for generating a foveated video display with sections having different resolutions uses a network channel for communicating video images having video sections of different resolutions, and includes a video transmission system for processing and transmitting the received video images over the network channel. The system assigns a larger portion of the network channel's bandwidth to a video section with higher resolution. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images.

摘要： Viewing angle characteristics of a liquid crystal display (LCD) are improved by reducing the number of subpixels in an image with mid-tone luminance values. In a preferred embodiment, a first table of entries associating subpixel intensity values and subpixel luminance values for a LCD in at least one viewing angle direction is provided. A target intensity value is determined from the first table, corresponding to the average subpixel luminance over a small number of adjacent subpixels. A second table of entries associates the target intensity values with intensity values above and below the target. The adjacent subpixel intensity values are modified according to the second table, thereby reducing the number of subpixels with mid-tone luminance values. The subpixel data is preferably processed within a portion of an application-specific integrated circuit (ASIC), contained within the display module.

摘要： A differential pulse encoding and decoding approach for binary data transmissions, such as binary frequency shift keying (BFSK) data transmissions, for sending and recovering a serial, binary digital data stream by differentiating the pulses thereof. A method and system are disclosed for transmitting from a transmitter to a receiver a digital data signal containing a stream of binary data bits having a first high value and a second low value. At the transmitter, the digital signal is transformed into a differential signal which contains pulses corresponding to transitions between the first and second values. The digital signal is transformed into the differential signal by an encoder which can be a differentiator circuit or an RC high-pass filter circuit. If frequency spectrum is a concern, a low-pass filter can filter the output of the encoder. The differential signal is then transmitted, and received by the receiver which reconstructs the original digital signal therefrom. The transmission of the differential signal can be by a transmission cable or by an FM transmitter and receiver. At the receiver, the digital signal is reconstructed from the differential signal by a decoder circuit which functions to produce a high voltage output signal when the input signal is higher than a reference high voltage, and a low voltage output signal when the input signal is lower than a reference low voltage. A low-pass filter can also filter the input to the decoder circuit.
