| 4. A method for de-interlacing interlaced video, comprising the steps of:
reading from a unitary memory each of two frames of video information at a rate of twice a normal frame rate;
performing, at a unitary combined de-interlacing and frame doubling circuit, two de-interlacing operations in parallel with
each other and at the same time, each de-interlacing operation being performed on a successive pair of video lines separate
from the other de-interlacing operation.
