How far can the signal travel?
Under perfect transmission conditions Class B HDBaseT
transmissions of 1080p video are capable of distances
up to 70m/230ft. Perfect conditions mean no electrical
interference, straight cable runs with no bends or kinks
and no patch panels or wall outlets. If some of the
above are factors in your installation then signal strength
and bandwidth can be compromised. If a cable run is
reaching the upper limit of the receivers’ capabilities,
then the signal can be boosted by way of an extender
set (TX & RX) or by simply using an in-line repeater. Our
transmission signals can be repeated up to 7 times
(700m) using HDBaseT technology.
What about 3D?
All of our matrix switches and most of our extender
products will pass-through a 3D Blu-ray signal. Coax
extender sets do not support frame sequential 3D (Blu-
ray), but will still pass-through interlaced stereo-scopic 3D
(Satellite etc.)
How do I control the sources?
Most of our HDMI distribution products support some
kind of IR pass-through from point-to-point extender sets
to pro and HDBaseT matrices. Most of the range now
supports wideband IR meaning it is compatible with any
IR device available on the market. Our Pro and HDBaseT
matrix range (Cat 5e) 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?
Yes. Our HD display adaptors require a 5v power supply
at the TV end to operate. It’s important that these are
powered locally and do not receive remote power from
the rack as there can be issues resulting from voltage
drop along the length of cable.
Are WyreStorm products compatible with
HDMI 1.4?
HDMI 1.4 refers to a list of ‘features’ that a device is
capable of supporting, including Ethernet channel, return
audio channel, 3D etc. 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.
• All WyreStorm equipment support HIGH-SPEED (or
“category 2”) HDMI cables that have been tested to
FAQ’S
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 color 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 matrix switches are legal and comply with
HDCP regulations. They do this by assigning a “key” to
every display connected to the switch. HDCP “keys” are
assigned to a display when connected to a HDMI device
normally. This doesn’t change when connected to a
switch; it just assigns more of them.
I can get 1080i but not 1080p at a TV
location
Firstly ensure that both the source is outputting 1080p
and that the TV is Full HD 1080p screen. If this is the case
then the receiver Cat 5e or Coax may need setting up
for long cable mode using the DIP switches. This useful
feature uses an alternative Equalisation method to re-sync
the signal over longer distances.
I cannot get a signal out from my A/V
receiver along a Cat 5e extender set
Check to ensure that the A/V Receiver isn’t adding CEC
(HDMI Control Protocol) to the outgoing signal, this can
sometimes have an effect on the HDMI signal.
