ABSTRACT:
A level standard signal including a level reference signal and an information signal is interposed in a particular horizontal scanning line (a 603-line) of an HD picture signal. An amplitude level of the HD picture signal is corrected according to the level reference signal in a level correcting section, and an input level of the level standard signal is changed to a recording level according to the level reference signal in a recording level standard signal generating section to generate a recording level standard signal. Also, peripheral horizontal scanning lines of the HD picture signal placed at peripheral portions of an image plane are deleted in a signal dividing section, and a TCI signal is generated. The recording level standard signal is interposed in the TCI signal to generate a composite signal, and the composite signal is recorded in a magnetic tape. The composite signal is reproduced and changed to another HD signal in which an output level standard signal including an output level reference signal and an output information signal are interposed in the particular horizontal scanning line.
