Abstract
A widescreen enhanced definition television system compatible with an existing television standard (e.g., NTSC) has provisions for utilizing a conventional television camera. The conventional camera is modified by replacing the conventional lens with an anamorphic lens or by modifying the scanning control signals to produce a widescreen television signal corresponding images with a widescreen aspect ratio (e.g., 5:3) greater than the conventional aspect ratio (e.g., 4:3). The widescreen television signal produced by the modified camera is coupled to an encoder without restriction of horizontal bandwidth required to conform to the existing television standard. The encoder produces a television signal encoded with components for producing widescreen images with enhanced horizontal resolution when processed by a widescreen receiver but suitable for transmission within a single transmission channel of the existing television standard. When processed by a conventional receiver, due to the nature of the encoding, an image with the conventional aspect ratio but, without significant artifacts is produced.
