ABSTRACT:
Sequential digital video frames are divided into two interleaved fields comprising even-numbered horizontal lines of pixels and odd-numbered lines horizontal lines of pixels respectively. The "even" field of a first standard frame is combined with the "odd" field of a second standard frame to form a first pseudo-interlaced frame of data for display; then the same odd field is combined with the even field of a third standard frame to form a second pseudo-interlaced frame of data for display, and so on throughout a continuing digital-video message. The data transmission rate needed is thus reduced by nearly a factor of two, or conversely, for a given data rate, nearly twice as much video information can be transmitted in the same time interval.
