A transmitter transmits a raster-type video signal. For each one of a plurality of active video segments of a frame of the video signal, the transmitter derives redundant data from the respective active video segment and inserts the redundant data into a horizontal blanking segment of the video signal.

A video system includes at least one video subsystem including a video source coupled to a mobile platform. The video source is configured to capture and transmit video data. A video processing system is configured to receive transmission of the video data from the video subsystem at a plurality of locations in which the video subsystem is configured to transmit the video data to the video processing system automatically when the video subsystem is in range of the video processing system at each of the plurality of locations.

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.
