Abstract
An apparatus for controlling the phase of a video data signal to effect color correction includes a video data memory and memory control circuit. Interlaced write and read portions of the memory cycle are selectively spaced in time within a memory read/write cycle to enable shifting the read portion by a selected fraction of the memory read/write cycle without affecting the write portion, whereby color correction is achieved.
