The research on interleaving informations further into the micro-aperture of NTSC spectrum space is held out presently. The goal of this paper is to give the quantitative analysis about this aperture while the image moves. We show one important result. The S/N of the signal interpolated in the aperture is over 20dB when the vertical and horizontal speed is within 0.41 ine/frame and 0.6 pixel/frame respectaly: very low speed of about 10' /sec with 4H viewing distance. The obtained result is applicable to the disscussion of Y/C separation based on frame memory comb-filter, and shows us the importance of the intrafield Y/C separation.
