摘要：An improvement to a motion picture distribution system providing a high qualitymotion picture system compatible with pre- existing NTSC systems and improvinghorizontal and vertical detail. The improvement includes a television camera having ananamorphic lens, an encoder coupled to the television camera, and a decoder at areceiver. The anamorphic lens can have an aspect ratio of two to one, and compresses anentire motion picture viewing field into the NTSC-standard, four to three aspect ratio, toproduce a horizontally-compressed image. The horizontally-compressed image is outputfrom the television camera as a horizontally-compressed-image signal. The encoderencodes the horizontally-compressed-image signal as a composite-wideband-videosignal having increased bandwidth, and generates a subcarrier-composite signal. Thecomposite-wideband-video signal may be directly broadcast to a receiver or recorded bya recording device for subsequent transfer to a receiver, if the receiver is NTSC-compatible, the decoder generates a decoded-subcarrier-composite signal for use by theNTSC-compatible receiver. If the receiver includes a high quality system, then the highquality system uses the subcarrier-composite signal directly, demodulating the entirebandwidth of the composite-wideband-video signal to generate a motion picture imagehaving a quality similar to a 35-mm film distribution print.
