    • Vertical and horizontal sync signals are separated from an NTSC signal inputted from an outside by an external input circuit and a luminance signal (Y) and chrominance signals (B-Y, R-Y) are extracted and converted into RGB data. External RGB data and RGB data formed by a software are processed and the resultant data is supplied to an output converting circuit. The RGB data is converted into analog signals of the luminance signal and chrominance signals of a television signal by using individual system clock signals and outputted. A clock generating circuit generates two kinds of dot clocks which are used for the output converting circuit. The dot clock which is generated from the clock generating circuit and is used for conversion of the luminance signal is phase matched so as to follow a jitter of a horizontal sync signal (H) separated by an external video input circuit.
    • 垂直和水平同步信号与由外部输入电路从外部输入的NTSC信号分离,并且提取亮度信号(Y)和色度信号(B-Y,R-Y)并将其转换为RGB数据。 处理由软件形成的外部RGB数据和RGB数据,并将结果数据提供给输出转换电路。 通过使用各个系统时钟信号将RGB数据转换成电视信号的亮度信号和色度信号的模拟信号并输出​​。 时钟发生电路产生用于输出转换电路的两种点时钟。 从时钟发生电路产生并用于亮度信号转换的点时钟是相位匹配的,以便跟随由外部视频输入电路分离的水平同步信号(H)的抖动。

    • A switching device that selectively changes a computer to be operated from multiple computers including a control unit that the control unit detects a cursor position on the computer to be operated based on coordinate data and a computer resolution of the computer to be operated, the coordinate data being generated by performing a same acceleration process as the computer to be operated, on relative coordinate data that has been acquired from a given pointing device, and the control unit selectively changing changes the computer to be operated according to the cursor position. It is thus possible to selectively change the computer to be operated without any dedicated software or requiring a given space for manipulation.
