Owner's Manual

Setup
These patterns are useful for setting up a display. Some
of
them
are repeated from
the Video Calibration section for convenience,
though
in some cases the help text
is
more detailed for the pattern in this section.
Evaluation
These patterns are useful for evaluating the picture in various ways. They can be
used for making decisions between different components, for example
if
you've
borrowed a
component
to see
if
it's
worth
adding to your system,
or
for evaluating
the differences between different picture
and
video processing modes
on
the display
and/
or
player.
Special note:
when
viewing the
Chroma
Alignment pattern, be aware
that
some
players have chroma errors in their
menu
display system, which can make the
"good"
and
"bad" samples look switched,
or
make
both
of
them
look bad, even
if
the actual pattern looks correct. The
important
thing
to remember
is
that
the
skinny diamonds should look symmetrical - there should be an equal
amount
of
colored stripe
on
the left
and
right sides
of
each vertical diamond,
and
the
top
and
bottom
sides
of
each horizontal diamond.
If
they don't look symmetrical, there
is
a
chroma
alignment problem with some
component
in your system.
SD Evaluation
These patterns are essentially the same
as
the Evaluation patterns,
but
encoded
in
480-line (SO)
resolution.
Many
displays have different processing for
SO
and
HO
content, so
if
you watch
OVOs
on
your system, these patterns can help you
evaluate
how
well your player
and
display handles them.
Contrast Ratio
These are the patterns needed to measure ANSI contrast, using a light meter. The
ANSI
contrast standard
is
titled
'~NSI/INFOCOMM
3M-20
11
,"
and
can be
purchased from
the
ANSI standards committee at www.ansi.org.
