Abstract

PURPOSE:To realize a common use among a horizontal deflecting circuit, a convergence circuit, a pincushion compensating circuit and others, by compressing a video signal of the using standard system down to 1/2 in time axis and thus realizing a reception of the video signal of present NTSC system. CONSTITUTION:A high-grade TV signal is demodulated by its demodulating circuit 46 and applied to a CRT19 via the switches SW3-SW5 to ensure a high-precision projection of an image having (2N+a) pieces of scanning lines (N: scanning number of standard type; a: an integer). Both the horizontal and vertical signals separated by a synchronous separating circuit 3 of the demodulating circuit 46 are supplied to a deflecting coil 23 via the horizontal and vertical deflecting circuits 22 and 25 and the switches SW1-SW2. At the same time, the using NTSC signal is applied to a synchronous axis compression delaying circuit 26, a burst gate 29 and a synchronous separating circuit 27 respectively. Then the 1H period of each line of a composite video signal is compressed to a 1/2 in time axis and then decoded through a decoding circuit 47 of the NTSC signal subjected to time axis compression.
