Video setup

The video setup menu allows the PMDT to deliver the best possible perfor-
mance, in the context of the system in which it exists.

TV type

TV Type

4:3 letterbox
4:3 pan & scan
16:9

The display setting describes two characteristics: the aspect ratio of your dis-
play device (traditional 4:3 or widescreen 16:9), and in the case of a 4:3 dis-
play, whether you prefer to watch movies in their original aspect ratio
(letterboxed) or in a full-screen “pan & scan” version. Having selected the ap-
propriate setting for your system and preferences, press

composite setup

Composite setup

0 IRE
7.5 IRE

In the NTSC world, there are two different definitions for the electrical signal
that defines “black.” The unit “IRE” represents a scale of 0 - 100 where 0
equals zero voltage in that signal, and 100 equals the brightest white that the
signal can contain. In most of the world, “black” is defined to exist at 7.5 IRE
units up from zero volts, but in Japan and a few other places, black is defined
as being at 0. This setting is normally preset at the factory to suit the market to
which the PMDT is being shipped, but you can change this should you need
to do so. (Note: The component outputs are unaffected by this setting.)

component setup

Component setup

0 IRE
7.5 IRE

There is no setup in the SMPTE component specification. Therefore, according
to the SMPTE standard for component video, the component outputs of your
PMDT should always be set to have 0 IRE setup.

However, some televisions do not store different black level settings for each
input. This limitation may cause you to want to introduce setup in your com-
ponent source, so as to make it match your other, normal composite and
S-Video sources. Otherwise, details in the dark areas of the PMDT’s picture
may not be reproduced, since they will be occurring below the threshold that
you set for black (using other sources).

Clearly, the best possible picture, with the greatest possible video dynamic
range, will be obtained by having component black reproduced where it be-
longs (0 IRE). This requires a display device (or video processor) that can
handle different input levels correctly. Use 7.5 IRE only if it is the only way to
