    摘要: A graphics subsystem including a RAMDAC for connection to a graphics bus implemented on an integrated circuit chip separate from a graphics processor. In one embodiment, the graphics processor is configured to render digital image information in response to graphics commands and to store the digital image information in a memory. The RAMDAC IC includes a conversion unit, which includes a color mapping unit and a digital-to-analog converter and is configured to convert a representation of the digital image information into one or more analog signals for driving a video display. The graphics subsystem further includes a Direct Memory Access (DMA) controller implemented on the second integrated circuit chip. The DMA controller is configured to generate read requests to retrieve the digital image information stored in the memory to thereby cause the digital image information to be provided to the conversion unit. The DMA controller is further configured to generate write cycles to cause digital RGB display data received from the color mapping unit, in the conversion unit, to be provided for storage in a specified region of memory. In another embodiment, the graphics subsystem may include a digital video interface implemented on the second integrated circuit chip. The digital video interface is configured to receive digital RGB display data from the color mapping unit and to provide an encoded digital video output to a digital video output port. The digital video interface is further configured to receive encoded digital video from a digital video input port and to provide decoded digital display data for storage on devices such as a digital VCR.

    摘要: A digital video transmission system that operates with three different video rendering paths. A first rendering path operates by receiving display requests and rendering bit-mapped graphics in a local screen buffer. The display information in that local screen buffer is then encoded and transmitted to a remote display system that recreates the content of that local screen buffer in a video buffer of remote display system. A second rendering path operates by receiving encoded video stream requests that can be decoded by the remote display system. Such encoded video streams are sent to the remote display system with minimal addition transport encoding. The third rendering path handles encoded video streams that cannot be handled natively by the remote display system. Such video streams may be either transcoded before transmission or decoded and stored within the local screen buffer.

    摘要: Techniques for use within computer systems that communicate with multiple different terminal systems using multiple different terminal protocols are disclosed. In one embodiment, a partial protocol converter module is installed in a computer server system to enable the computer server system to communicate with terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module directly accesses a screen buffer in the computer server system that is associated with the terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module detects updates to the screen buffer and encodes these display screen updates into a message using the native protocol used by the terminal system and then transmits that encoded message to the terminal system.

    摘要: Thin-client terminal systems allow server computer systems to be shared by multiple computer users. However, thin-client terminal systems that use analog signals can only be placed a limited distance from the main server computer system. On the other hand, thin-client terminal systems that rely purely on digital signals can be expensive to produce. A thin-client multiplier that combines the two different approaches communicates digitally with main server computer system such that it can be placed any distance from the main server computer system. The thin-client multiplier also provides output information received from the server system and electrical power to analog thin-client terminal systems and receives input information from the analog thin-client terminal systems. The received input information is provided to the server system for processing.

    摘要: In a system and method for a thin-client terminal system having a local screen buffer using a serial bus, a serial bus interface device receives encoded data from a thin-client server system. The serial bus interface device decodes the encoded data according to a serial bus data format and provides the decoded data to a thin-client control system. The thin-client control system distributes the decoded data for processing to a video processing system, an audio processing system, and an input/output control system. The thin-client control system also receives input data from input devices connected to the thin-client terminal system. The input data is processed and encoded according to the serial bus data format for transmission to the thin-client server system.
