Abstract
A television apparatus for displaying the picture information of an interlaced signal, such as a baseband NTSC signal, in a non-interlaced scanning format is described. When no picture change occurs, the picture information of the first and the second fields of the NTSC signal are displayed in alternate scan lines of the display of the apparatus, respectively, to form a picture frame during one vertical scanning interval. A signal, indicative that a picture change occurs in a section of the picture frame, is generated when a picture change occurs. The picture change indicative signal is obtained by using a frame comb filter to detect interframe picture variations. The picture change indicative signal causes the displayed picture information in that section of the picture frame to be derived from one field of the NTSC signal.
