    • A computer-generated image signal is analyzed to derive a set of alignment parameters for a television. These alignment parameters arc then used to configure the television accordingly. The alignment parameters may include aspects of the computer-generated image signal such as a vertical period, a horizontal frequency, a horizontal front porch, a horizontal active image time and/or a maximum RGB video level. The television may be configured to reduce its raster length to accommodate the compute generated image signal. Further, the values of the horizontal measurements for the active video time, front porch and frequency of the computer-generated image signals may be used to determine values for the television's horizontal picture size and position. Such values may be determined by computation or by table look up. In addition, other television alignment parameters such as upper and lower pin cushion, vertical bow, pin amplitude and/or horizontal angle may be determined. The RGB parameters of the computer generated image signal may be used to derive optimal brightness and/or contrast settings for the television.
    • 分析计算机生成的图像信号以导出用于电视的一组对准参数。 这些对准参数然后用于相应地配置电视机。 对准参数可以包括计算机生成的图像信号的方面,例如垂直周期,水平频率,水平前沿,水平有效图像时间和/或最大RGB视频电平。 电视可以被配置为减小其光栅长度以适应计算产生的图像信号。 此外,可以使用计算机生成的图像信号的有效视频时间,前沿和频率的水平测量值来确定电视机的水平图像尺寸和位置的值。 这些值可以通过计算或通过表查找来确定。 此外,可以确定其他电视对准参数,例如上下垫,垂直弓,针幅度和/或水平角。 计算机生成的图像信号的RGB参数可以用于导出电视的最佳亮度和/或对比度设置。
