Abstract
In this invention, the duplicate field included in a telecine signal that is produced from a movie film or the like by 2-3 pull down system is detected without failure, and completely removed before being encoded or transmitted. The result of the accumulation of the duplicate field in the telecine signal is regarded as an amount of noise resulting from the conversion of a film into the telecine signal. Then, a threshold is used as a reference for detecting the duplicate field and changed in accordance with the noise. In addition, a memory is provided to store the location of the duplicate field in the telecine signal, thus making it possible to surely eliminate the duplicate field at the same location even when the same video signal is received again.
