Television that conveys real-time information has become an indispensa
ble part of our fives. Its technology has advanced from the days of bl
ack-and-white sets to color models and to high definition television(H
DTV). HDTV has been contrived to provide the audience with greater imm
ediate appeal such as sensation of reality and power than the current
TV system does and its worldwide applications are expected to continue
to grow. Real world information which we obtain with our eyes is thre
e dimensional. It is reasonable, therefore, that we humans want an ima
ging system that produces pictures that are as natural and real as thi
ngs we see and experience every day. Three-dimensional television (3DT
V) is a very promising approach expected to satisfy such wishes. As te
levision technology matures and HDTV produces pictures as clear as mov
ies, 3DTV is now capable of providing real-time stereoscopic pictures
with high resolution. This paper outlines the studies that have been c
arried out about 3DTV as a post HDTV system. The themes of the paper a
re focused to such topics as human factors in relation to binocular pa
rallax, camera and display systems, and bandwidth reduction technology
