Abstract
According to a video information outputting apparatus, a video information receiving apparatus, a video information outputting method and a video information transmitting method, for receiving and outputting digital video information. The digital information is outputted in the same quality as it is, when it is certificated that an external apparatus operates according to a copy control information, while no information limited on copying thereof is outputted when it is not. It thereby prevents the information, which is outputted from the video information outputting apparatus to an external apparatus, from being used in other purposes than the original object thereof, thereby giving disadvantages onto the producer and/or copyright owner of the information.
