This paper presents a design of an optimized video encoder using a simple pipelined architecture. The proposed video encoder accepts conventional NTSC/PAL video signals. It also processes the PALplus video signal using an improved decimation process. The proposed encoder requires only 25 K gates, which is a 41% reduction in hardware compared with the systolic pipelined architecture of Oh, Choi, Kwon and Lee (see ibid., vol.43, no.3, p.965-71, 1997). The encoder has been designed in a 5-stage pipelined structure to assure stable operation. The overall performance of the encoder has been verified by using 0.65 μm CMOS gate array technology. The chip size is 5170 μm * 435O μm
