ABSTRACT:
A signal from an aspect ratio input means (3) is supplied to a code signal generating circuit (4). Further, a video signal from a signal source (1) is supplied to a code signal inserting and adding circuit (5), in which it is added with the code signal from the code signal generating circuit (4). The video signal into which the code signal is inserted and added is supplied to a video cassette recorder (VCR) (6) and thereby recorded on a recording medium (7). Further, a reproduced signal from the VCR (6) is supplied to an image processing circuit (8). The reproduced signal is also supplied to a decoder (9) which discriminates a code signal of the above aspect ratio. The code signal of the discriminated aspect ratio is supplied to the image processing circuit (8), thereby enlarging or reducing a reproduced picture. Further, the video signal in which the picture is enlarged or reduced is supplied to a receiver (10) having an aspect ratio of 16:9 and a reproduced picture enlarged or reduced is thereby displayed.
