Abstract: A device includes a transmitter that transmits, via an interface comprising first, second, and third transmission channels, video data having a 4:1:1 format to a display device. 4:1:1 represents a ratio of a sampling frequencies of a brightness component, to a first color difference component, to a second color difference component. The first and second color difference components of one pixel in a first horizontal line of a first frame of the video data are allocated and transmitted within two clock cycles of the first transmission channel. Brightness components of four pixels in the first horizontal line are allocated and transmitted within two clock cycles of the second and third transmission channels. The transmitter transmits the video data for all of the pixels of the first horizontal line, and thereafter, sets pixels in a second horizontal line as a target to be transmitted.

Abstract: A video, audio and graphics system uses multiple transport processors to receive in-band and out-of-band MPEG Transport streams, to perform PID and section filtering as well as DVB and DES decryption and to de-multiplex them. The system processes the PES into digital audio, MPEG video and message data. The system is capable of decoding multiple MPEG SLICEs concurrently. Graphics windows are blended in parallel, and blended with video using alpha blending. During graphics processing, a single-port SRAM is used equivalently as a dual-port SRAM. The video may include both analog video, e.g., NTSC/PAL/SECAM/S-video, and digital video, e.g., MPEG-2 video in SDTV or HDTV format. The system has a reduced memory mode in which video images are reduced in half in horizontal direction only during decoding. The system is capable of receiving and processing digital audio signals such as MPEG Layer 1 and Layer 2 audio and Dolby AC-3 audio, as well as PCM audio signals. The system includes a memory controller.

Abstract: An integrated receiver with dual channel transport stream decoding and delivery substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides multiple time-base clocks for two transport streams. Transport processor circuitry uses multiple PCRs to track transport streams through decoding, storage and or delivery of the decoded signals for display. Provision of a multiple time-base clock for decoding and delivering multiple transport streams allows display of the two decoded audio-video signals on independent monitors.

Abstract: A system for transmitting and receiving an uncompressed HDTV signal over a wireless RF link includes a clock that provides a clock signal synchronized to the uncompressed HDTV signal and a data regeneration module connected to the clock, which provides a stream of regenerated data from the uncompressed HDTV signal. A demultiplexer demultiplexes the stream of regenerated data, using the clock signal, into an I data stream and a Q data stream. A modulator connected to the demultiplexer modulates a carrier with the I data stream and the Q data stream. A demodulator receives the carrier and demodulates the carrier so that the I data stream and the Q data stream are recovered. A multiplexer connected to the demodulator multiplexes the I data stream and the Q data stream into a single stream of HDTV data so that the uncompressed HDTV signal is recovered.

Abstract: A system and method to provide cost effective, portable and convenient access to the Internet and other personal computer applications from any location within a predetermined distance from a desktop personal computer (PC). According to one aspect, a compact handheld terminal functions as a user interface device and communicates via an FM frequency hopped radio link with a base station which is located near and connected with the desktop PC. The handheld terminal allows home users to conveniently and remotely interface with their desktop PC with a freedom of movement similar to that of using a laptop PC while allowing an inexpensive network connection. The FM frequency hopped radio link carries the appropriate video, audio, keyboard and mouse signals between the desktop PC and the handheld terminal. The approach may be adapted to short range transfer of high quality video in a variety of applications.

A client system includes a TV, conventional input devices, such as a keyboard and a mouse, and a set top box for interfacing the TV to the network. The server maintains a system work area and multiple processes corresponding to user applications. The system work area is partitioned in the server into multiple independent, simultaneously active desktops, one desktop for each of the client systems. Individual processes are mapped to the appropriate desktop. Multiple frame buffers are maintained in the server, such that a different frame buffer is assigned to each client system. Each desktop is rendered within the server and stored in the corresponding frame buffer. The contents of each frame buffer are transmitted over a transmission medium to the set top box of the corresponding client system.

Abstract: A solid-state image pickup apparatus for generating image pickup signals produced by a solid-state image sensor. The image sensor is driven at a data rate of f.sub.s1 with a predetermined phase. Digital luminance signal Y and two digital chrominance signals C.sub.R, C.sub.B are generated by a first digital processing unit, operated at a clock rate related to the data rate of f.sub.s1, from the digitized image pickup signals. These signals are then converted by a second digital processing unit into signals Y, C.sub.R and C.sub.B having a data rate related to f.sub.s2. The second digital processing unit performs bandwidth limitations on these signals by a half band filter having a passband f.sub.s2, f.sub.s2 /2 and f.sub.s2 /2 and performs data rate conversion of from 2f.sub.s1 to f.sub.s2, from f.sub.s1 to f.sub.s2 /2 or f.sub.s2 /4 and from f.sub.s1 to f.sub.s2 /2 or f.sub.

Abstract: A method and apparatus for signal transmission in which each of a series of input signals (e.g., RGB baseband video signals) is frequency-modulated onto an intermediate frequency. The intermediate frequency signals thus produced are then fed through RF mixers and frequency-shifted to an assigned transmission channel. Each channel is then RF multiplexed into a composite signal for providing a complete set of input signals to one or more monitors. Each monitor is provided with a splitter to divide the composite multiplexed signal into its RF components, which are fed to RF mixers to be shifted back to intermediate frequency signals. Demodulators convert these intermediate frequency signals to output signals corresponding to the input signals.

Abstract: At least a first and a second digital signal, both in parallel form, are converted to a single serial signal and transmitted from a digital color decoder to a signal processing unit so as to avoid picture disturbances in the signal processing unit. The first digital signal is dependent on the instantaneous value of a clock frequency used in the decoder for processing a digital color picture signal, and the second digital signal is dependent on the instantaneous value of a chrominance subcarrier frequency generated in the decoder and used for color decoding.
