摘要： A method for measuring motion at a horizontal and vertical position between video fields of opposite parity comprising the steps of measuring the signal values of at least two vertically adjacent pixels from a video field of one parity and at least two vertically adjacent pixels from a video field of the opposite parity such that when taken together, the pixels represent contiguous samples of an image at said horizontal and vertical position, and determining whether the signal value of any of the pixels lies between the signal values of adjacent pixels in the field of opposite parity and in response outputting a zero motion value, otherwise, outputting a motion value equal to the lowest absolute difference between any of the pixels and its closest adjacent pixel in the field of opposite parity.

摘要： A system for enhancing brightness and resolution while correcting certain types of convergence, geometry, color and luminance errors caused by the display device, the viewing position or both. This system involves merging images from two or more sources, overlapping and offsetting pixels, or overlapping scanning lines ‘merged raster’ in a CRT or several (3) ‘merged rasters’ in color CRTs, and adjusting video content and timing, to compensate for the current viewing position and/or device distortion. Display and/or viewing perspective distortion characteristics are measured from the observers viewing position for the raster or each non-converged raster and stored as correction factor data in non-volatile memory. This data is used to modify the digital addressing of video image memory, to read and to correct pixel data for each image, adjust color, modify magnitude, and to drive the displays video amplifier at the correct time with the corrected amplitude and image data. Making these changes within the video path provides substantial improvements in image quality and in cost savings.
摘要翻译：一种用于在校正由显示装置引起的某些类型的融合，几何形状，颜色和亮度错误，观看位置或两者的同时增强亮度和分辨率的系统。该系统涉及将彩色CRT中的两个或多个源，重叠和偏移像素的图像或重叠的扫描线“合并光栅”合并在CRT或多个（3）“合并栅格”中，并且调整视频内容和定时，以补偿当前的观看位置和/或设备失真。显示和/或观看透视失真特征是从观察者对于光栅或每个非会聚光栅的观察位置进行测量，并作为校正因子数据存储在非易失性存储器中。该数据用于修改视频图像存储器的数字寻址，读取和校正每个图像的像素数据，调整颜色，修改幅度，并在校正的幅度和图像数据的正确时间驱动显示器视频放大器。在视频路径中进行这些更改可以显着提高图像质量和节省成本。

摘要： As a digitized representation of an intermediate frequency television signal moves through a demodulator it undergoes a number of processes, including conversion from an analog signal to a digitized data, digital signal processing of the digitized data, and the like. The rate at which the digitized data moves through the digital signal processor of the demodulator for processing is referred to as the data rate of the DSP. The demodulator can vary the data rate based on a selected television channel, thereby reducing the level of interference at the demodulator resulting from noise.
