摘要
A feedback path to the processor for a video signal in a computer. The video image data is not normally subjected to benchmark testing because it would make it susceptible to illegal copying. The digital video output signal is sent back to the processor one pixel at a time, with a delay between pixels equivalent to one line time. The result is that the pixel feed is so slow that digital copying is impractical. A lockout timer allows the pixel data to be sent to the processor only at intervals.
