METHOD AND APPARATUS FOR CHANGING PHASE OF VIDEO PROGRAM MATERIAL TAKEN FROM 24 FRAME PER SECOND FILM

摘要

A resequencer changes the ABCD grouping of a sequence of videofields derived from a motion picture film via 3-2 pulldown so as to allow thatsequence of video fields to be cut into or edited with a second sequence ofsimilarly derived video fields, the cut or edit occurring at any desiredposition, without any artifacts. The resequencer comprises eight field stores.In each video field time, an input video field is stored into one field storeandan output video field is read from a different field store. The particularfieldstores into which fields are read and written in each video field time arechosen so as to achieve the desired change in ABCD grouping.
