1. Introduction
SPATZ HDMI-GIGALAN is another product for transmitting HDMI or DVI over
IP networks or extending these signals over a single UTP cable (CAT5e/6/7).
The system is using 1000BaseT technology so any structured cabling that
has been approved for Gigabit Networks will work for the HDMI-GIGALAN
system. Due to a highly integrated ASIC we can offer HDMI over IP in a cost
effective way for Real time video.
Compression and Latency
The transmitter works with a special compression technology that creates
fixed data stream of 120 Mbps. The system works with an adaptive motion
detection which results in a very high quality for still pictures and an
extreme low latency of less than 3ms. If your signal contains motion the
system will apply a multi stage prefiltering which will show up as slighty
visible compression artefacts. We recommend to test the system with
motion video before specifying for such an application.
The image quality of typical PC signal up to 1920 x 1200 is exceptional and
very difficult to tell apart from a direct connection. We therefore think that
this product is well suited for digital signage of any kind or distributing of
content with little motion with the advantage of big distances at very low
system cost.
The HDMI-GIGALAN works best with GIGABIT switches. However they have
the ability to detect the network speed and can reduce the transmission
rate for 100BaseT equipment.
The proprietary network signal can only be decoded by the HDMI-
GIGALAN-RX and not by any Software decoders or media clients.
Point to Point configuration
The HDMI-GIGALAN-TX and HDMI-GIGALAN-RX are using the Multicast
protocol, which means that units with same multicast adresses can join this
group and communicate with each other.This technology is vastly
reducing the network load, as only one datastream is created
independently of the amount of recipients. If you would like to use the
HDMI-GIGALAN on existing networks or switchers they need to
support IPv6 or IPv4 and IGMP or CGMP (cisco) protocol. The multicast
adress room is 224.0.0.0 to 239.255.255.255.
If you intend to use unmanaged switches you have to adjust the
transmitters Dip Switches to different adresses. You can have up 16
transmitters and an unlimited amount of receivers in an unmanaged setup.
