Abstract
Encoding apparatus, situated at the transmitter and employing digital processing, transforms an NTSC format color television signal to a serial time-multiplexed IYQY format which (1) preserves the blanking level of the NTSC signal, and (2) time compresses the color information in a manner which permits low-distortion restoration of the NTSC format color signal by decoding apparatus, situated at the receiver and employing digital processing. The transformed format is particularly suitable for communication over a DBS (direct-broadcast satellite).
