Line 7: Progressive segmented frame technique is equivalent to [[Telecine\|2:2 pulldown]] pattern. "PsF" seems to be a term used in production, while "2:2 pulldown" is a term used for broadcast. Charles Poynton, an authority in digital television, makes the following remark in his book: "Proponents of [PsF] scheme claim compatibility with interlaced processing and recording equipment, a dubious objective in my view."<ref>{{cite web\|url=http://books.google.com/books?id=ra1lcAwgvq4C&pg=RA1-PA62&vq=segmented+frame&dq=segmented+frame&sig=8ZAl0RqzUYnyxQSmjxiIw4ZJDbE\|title=Charles Poynton, "Digital Video and HDTV: Algorithms and Interfaces"}}</ref> He does not question the usefulness of progressive segmented frame ~~to deliver progressive material~~ for ~~the end~~broadcast ~~users~~purposes; just one paragraph above he explains the technique to transfer movies to video: "Film is transferred to 575i video using 2:2 pulldown: Each film frame is scanned into two video fields (or frames); the film is run 4% fast." ==References==
