Abstract :
The design and implementation of a digital video application-specific integrated circuit (ASIC) that performs the line interpolation of the missing color samples of a digitized multiplex analog component (MAC) video signal are described. The main part of this circuit is a specific 864*8-bit memory designed as a double-chroma digital delay line. The design is based on 2- mu m double-metal N-well CMOS technology. The chip area is 35.6 mm/sup 2/ and it operates with a clock rate of 13.5 MHz. This circuit, which also performs phasing and blanking of the 8-bit digitized luminance and chrominance samples, is a part of a digital decoder used for the reception of video TV signals coded according to the MAC family system.<>
