Latest Patents

Richard Griffen holds a patent for a "Video processing system having improved synchronization." This invention involves a video processing apparatus that receives an analog color composite video signal, which includes a color burst. The system generates a D2 digital signal sampled at a specific phase relationship with the color burst using a sampling clock. The analog video signal is phase-shifted to create a 'zero' video signal. By adding the analog video signal and the phase-shifted video signal, a sum video signal is produced. This sum video signal is then clocked into a latch by the sampling clock signal. The output of the latch is delayed by two clock pulses to create a delay clocked video signal. This delay clocked video signal is compared with the output of the latch to generate a comparing signal. The comparing signal is utilized to adjust the phase of the sampling clock signal, thereby automatically controlling the phase relationship between the analog video signal and the sampled digital signal.
