for Quality
Digital computer data is relatively tolerant of
transmission losses, but video data is not. If you
want a sharp, clear picture on your displays,
accurate transmission of data bits is essential.
That means it’s important to purchase a high
quality HDMI cable. Unfortunately, quite a few
inferior cables, not tested or certified to exact-
ing specifications as are Belden products, are
being marketed today.
What you’ll see on your displays when you use
inferior cables depends on your system sources
and the capabilities of your TV, but might
include problems like pixel loss, colors not as
deep as they should be, an increase of image
graininess, the presence of artifacts – and, pos-
sibly even a total loss of picture.
Currently, 1080p (Category 2, version 1.3b) is
the highest resolution format used for broad-
casting and consumer distribution of video
content. In the term "1080p" the number 1080
represents 1080 lines of vertical display resolu-
tion, and the letter p stands for a progressive
(non-interlaced) scan. Belden’s HDMI cables are
performance tested to verify their capability
to handle transmissions in advanced high defi-
nition applications based on 1080p. Our digital
video/audio cables are also UL-rated for resi-
dential and commercial installations (including
in-wall use).
Belden verifies HDMI cable performance, among
other methods, with a technique known as an
"Eye-Pattern" test. Other critical electrical para -
meters tested by Belden include Impedance,
Attentuation, Crosstalk, and Skew.
In eye pattern testing, the digital data signal
traveling along the cable is repetitively sampled
and applied to the vertical input of an oscillo-
scope, while the data rate is used to trigger the
horizontal sweep. The result seen on the scope
is a series of lines that might be thought of as
signal traces. In the very middle of the eye dia-
gram is a flattened hexagon called the "eye
mask." If signal traces cross into the region of
the eye mask, the cable fails the test (see the
pattern on left in the Figure). On the other
hand, an acceptably-performing cable (or other
HDMI component) will yield a wide “eye” area.
In general, if a source – a device generating an
HDMI signal – produces a good signal and if
the HDMI cable delivers that signal at least well
enough to pass the eye pattern test, the display
in your home theater setup should be able to
reconstitute the digital signal without errors.
(See Belden’s Eye Pattern test results.)
