Abstract
An additive video information inserting device includes a MUSE-NTSC converter, and an additive video information encoder for receiving an output video signal of the MUSE-NTSC converter and inserting into the video signal an additive video information indicating a frame mode for the video signal. The additive video information is so set as to correspond to a frame mode in a conversion operation of the MUSE-NTSC converter. The additive video information is inserted into a predetermined position in a vertical blanking period of the video signal.
