How do I control the sources?
All of our HDMI distribution products support IR pass-
through from point-to-point extender sets to AMP and
HDBaseT matrices. Most of the range now supports
wideband IR meaning it is compatible with any IR device
available on the market. Our PP and HDBaseT matrix
range (Cat 5e/Cat6) has IR pass-through from each of the
outputs and has discrete IR outputs at the switch end,
meaning you can have multiple identical sources yet the
IR would be routed only to the applicable source.
Do I need power at the TV end?
It depends on the WyreStorm device. Products with
one-way PoH or PoE technology require local power at
the Transmission end to power the receiver remotely,
but products with two-way PoH or PoE can be locally
powered at either the Transmitter OR Receiver ends,
depending on which location offers best power availability.
Products without PoH or PoE technology require local 12v
or 5v DC power at both ends for both units to operate.
Check your instructions carefully for details.
Are WyreStorm products compatible with
high speed HDMI cables?
HDMI 1.4 refers to a list of ‘features’ that a device is
capable of supporting, including Ethernet channel, return
audio channel, 3Detc. Due to the continuously evolving
nature of the technology, HDMI Licensing LLC have now
decided to simplify terminology by testing and referring to
cable in terms of STANDARD or HIGH-SPEED rather than
in generations 1.3, 1.4 etc.
• STANDARD (or “category 1”) HDMI cables perform
at speeds of 75Mhz or up to 6.75Gbps, which is the
equivalent to a 720p/1080i signal – These HDMI cables
are NOT recommended.
• All WyreStorm equipment support HIGH-SPEED (or
“category 2”) HDMI cables that have been tested to
perform at speeds of 340Mhz or up to 10.2Gbps, which
is the highest bandwidth currently utilised over an HDMI
cable and can successfully handle 1080p signals including
those at increased colour depths and/ or increased
refresh rates from the Source. High-Speed cables are also
able to accommodate higher resolution displays, such as
WQXGA cinema monitors (resolution of 2560 x 1600).
What about screens with different
resolution capabilities?
When sending a signal point to point a TV will
communicate it’s capabilities to the source, then the
source will output a suitable signal that compatible (i.e.
1080p Stereo audio). If you were to use a matrix switch
with three 1080p screens and one 1080i screen, the
resultant image would be 1080i across all screens. The
matrix switches do not scale per output but instead
negotiate with the source a signal that all screens are
capable of supporting.
How does the Matrix cope with HDCP?
HDCP (High Definition Copyright Protection) is a feature
built in to HDMI devices to prevent theft of or illegal
distribution of HD content. Unlike competing products,
WyreStorm equipment are legal and comply with HDCP
regulations.
They do this by assigning a “key” to any display
connected to the device. HDCP “keys” are assigned to a
display when connected to a HDMI device normally. This
doesn’t change when connecting to an extender, receiver
or matrix switch; rather keys are duplicated or more are
assigned.
I can get 1080i but not 1080p at a TV
location
Firstly ensure that both the source is capable of outputting
the higher resolution and that the TV supports that screen
resolution.
If this is the case then the distribution device may require
EDID management setting up using the DIP switches. This
useful feature provides a successful “send and receive”
to ensure swift and stable EDID negotiation between the
source and display.
