ABSTRACT:
The present invention relates to a signal processing apparatus and method, a recording medium, and a program, in which a more preferable class can be easily selected. A region extracting unit151extracts a class tap from an input composite video signal, and pattern detecting units152to154detect patterns for classes by using different predetermined methods. A class-code determining unit155determines a class based on information from an evaluation table156, and a coefficient memory157supplies a predictive coefficient corresponding to the class to a predictive computing unit159. The predictive computing unit159performs predictive computing based on a predictive tap supplied from a region extracting unit158and the predictive coefficient supplied from the coefficient memory157, so that a component Y signal is generated and is output therefrom. The present invention can be applied to a television receiver.
