Abstract: A band compression transmission system for video signal comprises a sampling circuit wherein a video signal having a maximum frequency f.sub.m and satisfying the formula f.sub.c =(N/M).times.f.sub.H (where M and N are positive integers satisfying the relationship N>M, where N/M is an irreducible fraction, and f.sub.H is the horizontal scanning frequency of the image signal) and with a frequency of less than or equal to twice the maximum transmission frequency of the transmission path, are given a first sub-Nyquist sampling by sampling signals with a frequency f.sub.c which is larger than the maximum frequency f.sub.m and where the phases of odd-numbered fields and even-numbered fields differ by 180.degree., and digital-to-analog converters to which sampled signals are converted into analog image signals.

Abstract: A band compressed video signal transmission system is provided with a sampling circuit for sampling a video signal having a maximum frequency f.sub.m by a sampling signal which has a frequency f.sub.c which satisifies a formulaf.sub.c =(N/M).times.f.sub.Hand is less than or equal to two times a maximum transmission frequency of an existing transmission path and is higher than the maximum frequency f.sub.m (where M and N are integers satisfying a relation of N>M, N/M is an irreducible fraction and f.sub.H is a horizontal scanning frequency), a DA converter for converting a sampled signal into an analog video signal, and a transmission path.
