We noticed the word "D-terminal" in catalogues for recently released
TV sets. A "D-terminal" is a digital broadcast signal connector which
joins a digital satellite broadcast tuner and a TV set.
Corresponding video signal format
||480i, 480p, 1080i
||480i, 480p, 1080i, 720p
||480i, 480p, 1080i, 720p, 1080p
i (interlace): interlaced scanning
p (progressive): progressive scanning
D-terminals, which the EIAJ (Electronic Industry Association of Japan)
provided, were adopted for use in digital satellite broadcast tuners.
A strong point of D-terminals is that they include video signals (Y,
Po, Pr) and control signals which are able to distinguish a video signal
format, allowing only one necessary connector to hook up.
TV receivers currently have two systems; a present standard television
(SDTV) receiver and a Hi-Vision (HDTV) receiver. There is also a variety
in TV sets, in the number of scanning lines and scanning format. For
this, D-terminals are provided which are compatible to each visual signal
TV sets which are not equipped with D-terminals should be connected
to a S-terminal for standard video signal (480i) and to a Component
terminal for Hi-Vision video signal(1080i) .
