摘要： A CMOS integrated circuit that comprises a graphics controller system that consists of a graphics engine and video memory together with some interface blocks, a PCMCIA host adapter, an infrared interface for generating video images on a LCD or CRT display unit, and a video stream interface for receiving video signals. Since the video memory is integrated on the same integrated circuit as the graphics controller, no package pins are required for the memory interface. The pins thus saved are used to provide access to an on-chip PCMCIA host adapter. The internal memory interface is 128 bits wide. Simultaneous performance improvement and power dissipation reduction is achieved because of the wide memory interface and the elimination of the large parasitic capacitances associated with a package pin connection.

摘要： An apparatus and method for handling special windows in a display comprises a window manager in an operating system that is called by application programs to create special windows. The window manager embeds static key signals including encoded special window information, such as the coordinates of a window area to be specially processed, into a video RAM. An existing video interface scans the video RAM and transmits display information, including the key signals, to the display. The present invention further comprises a window decoder in the display, that detects the key signals, extracts the encoded special window information, and controls display circuitry performing the desired special processing. The key signal encoding scheme does not create visually discernible display aberrations that could distract the user or interfere with normal window management.
摘要翻译：用于处理显示器中的特殊窗口的装置和方法包括操作系统中的窗口管理器，由应用程序调用以创建特殊窗口。窗口管理器将包括编码的特殊窗口信息（诸如要特别处理的窗口区域的坐标）的静态键信号嵌入到视频RAM中。现有的视频接口扫描视频RAM并将显示信息（包括键信号）发送到显示器。本发明还包括显示器中的窗口解码器，其检测关键信号，提取编码的特殊窗口信息，并控制执行所需特殊处理的显示电路。密钥信号编码方案不会产生视觉上可辨别的显示像差，这可能会分散用户的注意力或干扰正常的窗口管理。

摘要： Dynamic adjustment techniques for aligning video images in cathode ray tube (CRT) devices are disclosed. A host computer stores correction factor data and video image data in video graphics controller RAM. The host computer processes and transmits the correction factor data, representative of the cathode ray tube distortion characteristics, to the CRT device during the retrace time of the electron beam and video image data during the trace time. The correction factor data may be generated by a vision system, a gain matrix table, interpolation engine or manual methods. Circuitry, within the CRT device, for separating the correction factor data from the video signal is disclosed along with the methods and apparatus used to decode correction data. Data can also be transferred from the monitor back to the host computer over the video connector.
