Abstract
Abstract Video signal compression apparatus includes a memory for storing two fields of image data and providing fields of image data separated by one frame intervals. Frames of video signal are composed from the respective ones of the fields. The field types (e.g., odd or even) of respective fields are determined. Flags are associated with composed frames to indicate if a field of respective frames may be repeated upon reproduction, and which field of the composed frames should be displayed first.
