Abstract :
NHK has developed three ADTV (advanced definition television) systems that comply with US Federal Communication Commission´s decision to maintain compatibility with existing NTSC systems: narrow-MUSE (multiple subNyquist sample encoding), NTSC (National Television System Committee)-compatible MUSE-6, and NTSC-compatible MUSE-9. All three systems use program materials produced in the 1125/60/2:1 format converted to the 750 line format and therefore can transmit a vertical resolution of approximately 750 TV lines. Among the three systems, narrow-MUSE has the highest quality, because there are no NTSC compatibility constraints. NTSC-compatible MUSE-6 has both NTSC and 6-MHz channel compatibility. So does NTSC-compatible MUSE-9, which also provides higher moving resolution by introducing a 3-MHz augmentation channel. The authors describe the features of these systems and the band compression techniques used
