Blu-ray Ready
The
Splitter Unit
is able to support high definition video such as DVD or Blu-
ray and multi-channel audio, and carry the best signal from source to displays;
the high bandwidth allows for the transmission of large amounts of information
at a very high rate of speed.
Blu-ray uses a blue-violet laser to read and write data, while current
optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-
RAM rely on a red laser to read and write data. Despite the different type
of lasers used, Blu-ray uses a blue-violet laser (405nm) that it has a
shorter wavelength than a red laser (650nm), which makes it possible to
focus the laser spot with even greater precision. This allows data to be
packed more tightly and stored in less space, so it's possible to fit more
data on the disc even though it's the same size as a CD/DVD.
Operation
The quality of the output signal will depend largely upon the quality of video
source, cable and display device used. Low quality cables degrade output
signal causing elevated noise levels. Please use the proper cable and make
sure the display device is capable of handling the resolution and refresh
rate selected. Interference from nearby electrical devices can have an
adverse effect on signal quality as well.
