Abstract: An efficient software-based method for converting Yuv color video pixel data to RGB color video pixel data for display on a computer video screen. The Yuv pixel data is used to construct an index value into an RGB LookUp Table (RGB LUT) which contains corresponding RGB video pixel values. The corresponding RGB video pixel value is then used to display the color video pixel data on the computer screen. In a first embodiment a 24-bit Yuv value directly indexes an RGB LUT containing 24-bit RGB values. This embodiment preserves all of the original color information. In a second embodiment a 24-bit YUV value directly indexes an RGB LUT containing 16-bit RGB values (565 RGB). The 16-bit RGB values are preselected to preserve the luminance component with minimal error by shifting any luminance error into larger chroma errors.

Abstract: A plurality of parity bits is generated for serial transmission of a word of data bits, and the plurality of parity bits is modified before transmission to encode a sideband signal. The word of data bits and the plurality of modified parity bits are serially transmitted. In another embodiment, a serially-transmitted code word comprising a word of data bits and a plurality of parity bits is received, wherein the parity bits have been generated by an encoder and transmitted with the data bits. It is determined whether the parity bits were modified by the encoder to encode a sideband signal, and at least one of error detection and error correction is performed using the parity bits.

Abstract: A word of data bits is received and a plurality of parity bits for serial transmission of the data bits is generated. The word of data bits and plurality of parity bits are transmitted, wherein the parity bits are generated and transmitted with the data bits, wherein the parity bits are generated in accordance with a parity scheme that ensures that at least one binary transition occurs within each set of n consecutively transmitted bits, wherein n is a specified number. In another embodiment, a serially-transmitted code word comprising a word of data bits and a plurality of parity bits is received, wherein the parity bits are generated by an encoder and transmitted with the data bits, wherein the parity bits are generated in accordance with a parity scheme that ensures that at least one binary transition occurs within each set of n consecutively transmitted bits, wherein n is a specified number.
