I. The movement toward HDTV?
The original impetus for HDTV came from wide-screen movies. Soon after wide-screen was introduced, movie producers
discovered that individuals seated in the first few rows enjoyed a level of participation in the action not possible
with conventional movies. Evidently, having the screen occupy a great field of view (especially peripherally) significantly
increases the sense of "being there".
Early in the 1980s, movie producers were offered a high-definition television system developed by Sony and NHK
in the late 70s. This system (called NHK Hi-vision) and its variants are capable of producing images having essentially
the same detail as 35 mm film[1]. With these systems, a scene could be recorded, played and edited immediately,
and then transferred to film. As a consequence, many of the intermediate delays in conventional film production
were eliminated. The new medium also offered a number of possibilities for special effects not possible in conventional
film production.
