TL;DR: In this paper, a system for reproducing a full-band luminance signal from a medium containing a previously recorded luminance signals with a high-frequency portion thereof compressed in dynamic range is presented.

TL;DR: In this article, an improved video signal recording system for recording a full bandwidth video signal on a limited bandwidth medium is described, which includes an encoder coupled to an input terminal, and produces two signals; a luminance signal, having attenuated high frequencies subsampled so as to be folded into a spectral hole in the low frequencies, and being bandwidth limited to the limited bandwidth of the recording medium; and a combined signal including a chrominance and a motion component.

TL;DR: In this article, the luminance and chrominance components are separated into their luminance components for processing prior to recording and the chrominance component is converted to the color-under signals used in video tape recording.

TL;DR: An improved video signal recording system for recording a full bandwidth video signal on a limited bandwidth medium is described in this article, which includes an encoder 10, coupled to an input terminal 5, for adaptively processing a composite video signal in response to a motion representative signal, and producing two signals; a luminance signal Lr, having attenuated high frequencies subsampled so as to be folded into a spectral hole in the low frequencies, and being bandwidth limited to the limited bandwidth of the recording medium, and a combined signal C+Mr including a chrominance and a motion

TL;DR: In this paper, an encoder separates luminance and chrominance signal components of a composite video signal, and a motion signal is derived there from the frame-to-frame changes in the luminance signal.
