Presents a description of a one-chip up-converter architecture study, which performs a 1fH to 2fH, line-doubling, video up-conversion, for both 50 Hz-625 lines and 60 Hz-525 lines video systems. This architecture concept, the DMU (dual mode up-converter), converts the interlaced digital YUV video input signals into either a non-interlaced progressive 1 V field rate (50 Hz/60 Hz) or a interlaced doubled 2 V field rate (100 Hz/120 Hz) display format.
