Abstract

The system comprises a sampling device carrying out interfield offset subsampling of a video signal of the TV signal at a timing of a sampling pulse having a sampling frequency corresponding to an upper limit frequency of the video signal. A low pass filter has an output signal from the sampling device and passes a signal component having a biased portion resulting from interfield offset subsampling. The low pass filter has a cut off frequency equal to one half of the first sampling frequency. A second sampling device has an output signal supplied from the low pass filter. The sampling device carries out interframe offset subsampling of the output signal at a timing of a sampling pulse having a sampling frequency higher than half of the first sampling.
