This paper briefly considers future broadcasting technologies, includi
ng digital television as a system for the near future and three-dimens
ional television as a part of a system to be developed rather later. H
owever, due to limitations of space, this paper discusses only video t
echnologies in detail. First, the status of bit reduction technologies
for digital television is described and then satellite digital broadc
asting and terrestrial digital broadcasting are also discussed. The au
thors stress the necessity of the further development of digital video
compression technologies. Later, we discuss three-dimensional televis
ion, we describe requirements for the service and the present status o
f the technologies. And last, the paper considers the future prospects
for a three-dimensional television service.
