ABSTRACT:
A video signal that is representative of a wide scene comprises signal elements corresponding to a plurality of horizontal line intervals of a raster. A luminance component and two chrominance components are included in each horizontal line interval, in time-compressed sequential relationship. The video signal also incorporates information representative of a number in the range from zero to the difference between the aspect ratio of the wide scene and the aspect ratio of a scene represented by a conventional video signal format. This information determines the portion of the wide scene that is represented by a video signal of the conventional format derived from the video signal representative of the wide scene.
