Abstract
A plurality of simultaneously inputted signals are successively sent to an additional information decoding means by switching a switching means at prescribed timing, and additional information contained in each input signal is detected and decoded. Thus, a plurality of pictures corresponding to the additional information are generated from the input signals and displayed on the same screen.
