ABSTRACT:
Fuzzy logic based system and method for 3:2 pull-down film mode detection that detects whether a stream of NTSC video fields originate from film source via 3:2 pull-down technique. Fuzzy logic is used to generate a reference sequence of symbols from the stream of NTSC video fields. This reference sequence is adapted for indicating whether or not the video fields originate from film source.
