Narrow-MUSE is a system which NHK has developed for a simulcast ATV system in the United States. Adopting the same multiple subsampling technique as used in the MUSE system, and the new modulatin scheme, the Narrow-MUSE can deliver a high-resolution picture in the 6-MHz bandwidth without causing intereference with existing NTSC services. ATV laboratory tests conducted by the ATTC and ATEL were completed in February 1992. The good performances of Narrow-MUSE in interferernce, and picture/audio quality were confirmed by the results of the tests.
