ResumoThis article presents, in a tutorial fashion, the basic elements required for understanding compatible improvement techniques for NTSC color multiplexing using multidimensional filtering at the transmitter and receiver. It discusses the multidimensional spectrum of moving pictures and relates the form of this spectrum to different types of image material. It also presents the basics of multidimensional filtering that are key to the techniques we discuss for improving NTSC. Finally, systems for NTSC encoding and decoding using multidimensional processing are described.
