NTSC Compatible Advanced Television System and Implications for Studio Standards

In the broadcasting industry, the transition from today's NTSC to the inevitable HDTV is perceived to be the outlaying of major investments accompanied by the risk of low to nonexistent rates of return. An NTSC-compatible system approach can alleviate the initial economic shock, and with careful planning, can be designed to permit a phase-in period of several years. The migration concept discussed in this paper increments the degree of participation, especially by local broadcasters and smaller production companies, with corresponding incremental improvements in the picture quality delivered to the viewer at each step in the migration. — This paper describes a family of studio scanning standards that are appropriate to each of these levels of quality at the home display. Emphasis is placed on the use of progressive scanning rather than interlace in the first major upgrade to gain as early as possible the advantages that progressive scan offers in production and post-production operations. An exciting new progressive scan concept is described that holds promise of achieving for archiving purposes the full high-definition static and dynamic resolution within the same recording bandwidth required of today's interlaced HDTV equipment.
