A video signal transmission apparatus has the encoding means , operative when a predetermined unit of video signal is compressively encoded, for multiplexing identification data unique to this video signal in a user data region within an encoded bit stream, and the storing/decoding means for storing the encoded bit stream data having the unique identification data multiplexed therein, and, when transmission is requested from the outside, for decoding the encoded bit stream data and simultaneously reading the multiplexed unique identification data to verify whether it is unique identification data of a video signal to be transmitted.
