    摘要: 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.

    摘要: By introducing a new copy control system into video signals subjected to picture quality restriction satisfactory only in small-sized PMP displays, a new business model in which copyrighters, consumers and makers can have mutual prosperity is created. “A new copy control rule of prohibiting a video signal output with a picture quality equivalent to that at time of recording from being copied, but permitting a video signal sufficiently degraded in picture quality as compared with time of recording to be copied” is added to the copy-never, copy-one-generation, and copy-free states belonging to the conventional copy control rule. The quality for which the copyrighter can permit copying corresponds to half the current number of DVD pixels. If a quality restricting scheme of thinning out pixels to half compared with time of recording is used, therefore, needs of consumers desiring to enjoy PMPs are satisfied while protecting rights of copyrighters.
