Abstract

PURPOSE: To perform the delivery and recording of the signal in which no deterioration of video quality is made, by sampling TV signals transmitting or recording them, through the use of the sampling pulse having the frequency greater in the upper limit frequency in the occupied frequency band and lower the doubled frequency.
CONSTITUTION: The TV signal is sampled by using the sampling pulse having greater frequency than the upper limit frequency of the occupied frequency band width and lower than the doubled frequency. Further, the signal obtained is delivered to the reception side as it is or after suitable signal processing, and the recording to the recording media is made. In this case, the phase and frequency of the sampling pulse, n and m are taken an arbitrary positive integer respectively, and fk and fF are taken as the horizontal scanning number and the field frequency of TV signal, in the unit of fields of TV signal, the phase is shifted by 180° and the frequency is taken as nfk, or the phase is taken continuous and the frequency is taken as nfh±(m±1/2) fF. Thus,the signal delivery and recording without degrading the video quality can be obtained.
