ABSTRACT:
Apparatus for converting a digital video signal between two different formats, such as interlaced field and non-interlaced progressive frame, and which avoids filtering and sub-sampling of portions of the video data which are the same in either format. For conversion from interlaced field to progressive frame, only alternate fields of the signal are subjected to digital filtering. The filtered fields are then combined with the non-filtered fields, which are subjected only to an equivalent delay, to derive averaged frames which constitute a progressive frame video signal. For the reverse conversion, alternate scan lines of each frame are sub-sampled and averaged to derive a field which is then interlaced with a field formed by the remaining scan lines of such frame, thereby deriving an interlaced field video signal.
