ABSTRACT:
A system is disclosed for partially decoding an encoded widescreen, extended definition television signal into a signal that is compatible with existing consumer video cassette recorders (VCRs) and video monitors. The encoded signal is compatible with existing television standards to produce a video image having a conventional 4:3 aspect ratio. Signals representing side panel information, to be appended onto either side of the 4:3 center panel, are encoded in the signal and are not visible in the image produced by a conventional receiver. The disclosed system includes decoding circuitry which recovers the side panel signals, appends them to the center panel signal and changes the time correspondence of the total signal so that it represents an image having a 5:3 aspect ratio. Luminance and chrominance components of the decoded video signal are provided as output signals of the decoder and to input ports of a conventional video cassette recorder (VCR) such as an S-VHS or ED-Beta machine. The signal recorded on the VCR may be replayed on a widescreen monitor. The decoder includes an optional vertical interpolator to compress the widescreen picture vertically to generate a signal which produces a properly proportioned widescreen image when displayed on a conventional display device.
