Abstract: The present invention provides a digital wireless home computer system. One embodiment of the invention includes a computer with a first digital wireless transceiver, and a home input/output node having a second digital wireless transceiver for communicatively coupling to the first wireless transceiver. This node also has (1) an output device, communicatively coupled to the second wireless transceiver, for presenting an output presentation based on signals received from the computer via the wireless transceivers, and (2) an input device, communicatively coupled to the second wireless transceiver, for receiving input signals from a user interfacing with the home input/output node.

Abstract: The invention provides a method and apparatus for incorporating an appliance into a computer system. One embodiment of the invention has a computer with a first digital wireless transceiver, and an appliance unit with a second digital wireless transceiver for communicatively coupling to the first wireless transceiver. This appliance unit also has (1) an output device, communicatively coupled to the second wireless transceiver, for presenting an output presentation based on signals received from the computer via the wireless transceivers, and (2) an input device, communicatively coupled to the second wireless transceiver, for receiving input signals from a operator of the appliance unit.

Abstract: Dithering logic includes a number of programmable linear feedback shift registers (LFSRs), each configured to receive one of a number of color components (e.g., red-green-blue) of a video information signal as an input and to provide one of a number of dithered color components of the video information signal as an output. The dithered color components each include a greater number of bits than the color components. The LFSRs may be configured so that each LFSR includes a mask register configured to accept a characteristic polynomial. The dithering logic may be included in a set-top controller of a computer network that is organized to include a graphics processor communicatively coupled to the set-top controller. The dithering logic is thus configured to introduce pseudorandom noise into video information signals transmitted from the graphics processor to the set-top controller in accordance with one or more characteristic polynomials. Preferably, the characteristic polynomials are primitive polynomials.

Abstract: Video information which is organized in a first format is converted to a second format by first scaling the video information to produce scaled video information and then color correcting the scaled video information to produce color corrected video information at a network server. Scaling the video information may be accomplished by first applying a vertical scaling process to the video information to produce vertically scaled video information. Second, an anti-flicker filter may be applied to the vertically scaled video information to produce the scaled video information. The vertical scaling process includes a pixel-by-pixel conversion process wherein, for each group of six scan lines in a frame of the video information, color information for individual pixels which make up the group of six scan lines is scaled to provide color information for pixels in a corresponding group of five scan lines of a frame of the vertically scaled video information.
