摘要:
A method for effectively implementing a multi-room television system includes a digital base station that processes and combines various program sources to produce a processed stream. A communications processor then responsively transmits the processed stream as a local composite output stream to various wired and wireless display devices for flexible viewing at variable remote locations. The transmission path performance is used to determine the video encoding process, and special attention is taken to assure that all users have low-latency interactive capabilities.
摘要:
A method for signaling the type of access sought by a microprocessor to external memory. A microprocessor can read from or write into external memory. When the microprocessor initiates a read or write cycle, access signals indicating: the read or write cycle, the lower order address bits of the sought after code or data, whether code or data is sought, and bit-width of the sought after code or data, are provided to the inventions byte enable chaser circuit. If a read cycle has been initiated the byte enable chaser circuit encodes the signals into predetermined bit patterns and outputs the bit patterns on the microprocessor's byte enable signal pins. The bit-patterns are available for each bus cycle and specify whether code or data is sought, the length of the sought string, and the lower order address bits of the strings address. If a write cycle is initiated the byte enable signed pins indicate which byte(s) of the data bus are to be written into memory.

An apparatus and method for effectively implementing a wireless television system may include a communications processor and a transmitter device that combine at least one of a local-area network interface, a wide-area network interface, and one or more television data interfaces for effectively performing a wireless network transmission process. A transmitted stream from the wireless television system may be received via wireless network processing for viewing local-area network data, wide-area network data (such as Internet data), or television data by flexibly utilizing various electronic devices such as a notepad personal computer, a personal digital assistant (PDA), or a handheld TV remote control device.
摘要:
A multi-user host computer system comprises processor blades combined with terminal services blades to provide acceleration and proxy server functions for supporting a variety of remote terminals. For each remote terminal, the terminal services blade and proxy server functions may improve the video and graphics performance. This allows the multi-user host computer system to more efficiently support multiple users. The terminal services blade may include a graphics processor that manages a virtual display for each remote terminal and provides selective updates of sub frame data. Where appropriate, the sub frame data is encoded and transmitted over the network to the remote terminals. The terminal services processor also offloads and optimizes video data streams for the intended remote terminals and their respective network connections. Processor blades may include a baseboard management controller that utilizes advanced features for supporting remote KVM administration.
摘要:
A digital display system consists of an image modulator and multiple light modulators. An image processing system processes an incoming data stream, scans processed data to an image modulator and controls for the light modulators. Other user inputs and sensors are used to affect the processing and controls. The timing for scanning the processed data into the image modulators is controlled along with the intensity and wavelength of the light modulators. The display system may implement a spatial and temporal image processing, digital shutter controls, rolling shutter controls, sequential color output, adaptive dynamic sensor feedback, frame rate matching, motion compensated field sequencing and a variety of other techniques to produce a high quality display output. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.
摘要:
Image processing enhances display quality by controlling both the image modulator and the light sources to produce the best possible visual images. The image processing system utilizes a combination of user inputs, system configuration, design information, sensor feedback, pixel modulation information, and lighting control information to characterize the display environment on a per pixel basis. This per pixel characterization information is combined with one or more frames of the incoming real time display data. The image processing system processes each incoming pixel and produces a modified corresponding output pixel. Each pixel of each frame is processed accordingly. In addition to producing modified output pixels, the image processing system produces control information for the light sources. The light source control information can control individual lamps, tubes or LEDs, or can control a block or subset of the light sources. The resulting display has improved image consistency, enhanced color gamut, higher dynamic range and is better able to portray high motion content.
摘要:
A memory architecture having one or more shared high-bandwidth memory subsystems each coupled over a plurality of buses to a display subsystem, a central processing unit (CPU) subsystem, input/output (I/O) buses and other controllers. The display subsystem receives data from the high-speed shared memory for processing various video and graphics data types for display refresh. Additional buffers and caches are used for the subsystems to further optimize system performance. The display refresh path includes processing of the data from the memory subsystem for output to the display where the data enters the shared memory from an I/O subsystem or from the CPU subsystem.
