(under subclass 441) Subject matter wherein an input signal has all the lines scanned during one vertical period and an output signal requires at least two vertical periods to scan all the lines.
(1) Note. In the input signal the spatially adjacent lines are temporally adjacent while in the output signal the spatially adjacent lines are not temporally adjacent and the temporally adjacent lines are not spatially adjacent.
(2) Note. Often the conversion also changes the frame rate, but such frame rate conversion is not required for classification herein.
