Abstract
An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.
