The present invention is a digital element relates to a video signal of CCIR 601 digital video signal conversion device for converting such a video signal, the digital conversion and the like NTSC system of CCIR 601 video signal including a video signal of the PAL system by using a counter and a memory to provide a video signal conversion device, a decoding means for retrieving the timing reference signal; It receives the output from the decoding means for outputting the counting means counts by receiving a clock from outside; A write address and write enable signal, write address generating means for generating the chip enable signal; Read address, read address generating means for generating a read enable signal and the chip enable signal; First multiplexing means for selecting and outputting one of the write address and the read address; First latch means for latching the data; Storage means for storing data; Second latch means for latching the output data; The timing reference signal generating means for generating a timing reference signal; And multiplexes the data output by a second multiplexing means for outputting to the outside, there is an advantage that the hardware implementation of a simple and cost-effective and less error.
