ABSTRACT:
A time base corrector including a frame memory and a memory control. The memory control is microprocessor based and calculates the starting addresses of memory areas at which video data will be written to or read from the frame memory and the starting times of those sequences. The memory control receives information concerning the configuration of the time base corrector, the input video field sequence,the desired output video field sequence, timing components of the input and reference clock signals, TV standard, and operator commands to make these calculations. The results of the control are time base corrections for horizontal and vertical phase errors, horizontal and vertical positioning control, color frame sequencing, color correction of chroma phase, configuration delay adjustment, and other advantageous operations.
