A video tape recorder enables a normal video signal for an aspect ratio of 4:3 or a wide-picture video signal for a greater aspect ratio of, for example, 16:9 to be selectively recorded/reproduced onto and from a magnetic tape. In order to identify which of the aspect ratios the reproduced video signal is based on, a recording mode signal indicative of the aspect ratio is recorded on the magnetic tape together with the video signal. A code signal or a pilot signal is used for the recording mode signal. In the reproducing operation, the aspect ratio of a reproduced picture is recognized from the recording mode signal, and a signal indicative of the aspect ratio is delivered to an external device, such as a television set, together with reproduced video/audio signals. In a case where the reproduced picture is a wide picture and where the external device does not conform to the wide picture, the aspect ratio of the video signal is changed. A television set suited to the features of the video tape recorder is also disclosed.
