What is HDR – 10 bit Colour?
• Outside HDMI 1.4 spec
• Requires HDMI 2.0 inputs
• Most older 4K TVs and Projectors do

• Increases bandwidth

Colour Space?
When talking of HDMI standards you may have seen figures such as 4:4:4, 4:2:2 & 4:2:0. This refers to the Colour
Space of the HDMI signal and can greatly effect the amount of data being transferred on the HDMI cable.
• The Y is the Luma component (brightness) remains as a constant
• The U & V are the chrominance (colour) components
• The decrease in range of U+V colours means there are far less colour range available

Effects on cables and distances
• As speeds increased distance decreases significantly
• Maximum cable lengths for 4K 4:4:4 60Hz is 7M
• Not all HDMI cables are equal especially over longer distances
• Many HDMI over Catx or coax solutions only support 5.7 Gbps
• HDBaseT supports up to 10.2 Gbps

What is HDCP?
High-bandwidth Digital Content Protection – Is a form of digital copy protection designed to prevent copying of digital
video and audio content
The communication between source and display is often referred to as a ‘Handshake’ in which a source device requests HDCP
confirmation from display prior to sending an AV signal. The source (transmitter) encrypts the data to prevent eavesdropping or
copying en-route to the display (receiver).
The ‘Handshake’ is triggered by the HDMI Hotplug, at which time items connected will transmit EDID and HDCP details
Both source and display confirm that
they are HDCP compliant and negotiate
the maximum possible video resolution
and audio format that they both support
All manufacturers adhering to the HDCP standard must obtain a license, pay an annual fee and submit to various conditions.

HDCP 2.2
The next generation in content protection is HDCP 2.2. This is not backwards compatible meaning any HDMI products
you purchased in 2014, including 4K screens may not be HDCP 2.2 compliant.
HDCP 2.2 was designed to make the ‘Handshake’ more complex and now includes a check to confirm If the source
signal is local (by transmitting data and if not received by the sink within 20ms, the source kills the connection)
All items in your AV system will need to be HDCP 2.2 compliant in order to work. This could mean upgrading your AV
Amplifier, Bluray, Soundbar etc.

Understanding IP Video Distribution
Coming September 16
HDMI Over IP Distribution
What is HDMI over IP?
The new Blustream Multicast HDMI over IP solution is method of distributing HDMI video over a LAN (Local Area
Network) network infrastructure.
As all Blustream Multicast products are network products they are capable of distributing UHD video to any location that
a 1GB network can be extended to.
The system relies on the network switch to distribute and power (with PoE switches) each Blustream Multicast
component. This means the system size and distance capabilities is virtually unrestricted.
Designing a system around an network system typology allows you to place source hardware and display devices
anywhere throughout your property, no longer limiting you to centralizing your source hardware.
Unlike HDBaseT video distribution products it is not possible for different brands of HDMI over IP to work together.
HDMI over IP
What is HDMI over IP?
A typical installation will consist of the following products:
IP100UHD-TX
- 1x Blustream IP100UHD-TX Transmitter for each source device
IP100UHD-RX
- 1x Blustream IP100UHD-RX receiver for each display device
- Managed Gigabit Network switch/switches
- Cat cables linking Ethernet switch to Blustream Multicast products

HDMI over IP – System design
Difference between IP solutions and HDBaseT?
For
•Virtually unlimited system size.
•More cost effective for systems of 8+ displays
•Will not work with other manufactures HDMI over IP solution, more Blustream sales!
•Far less bandwith required for HDMI over IP video distribution using CAT cable. Will see less problems associated with cabling
and patch panels than HDBaseT which requires average 4GB for 1080P and 10+GB for 4K!
Against
•HDMI over IP represents lower video quality because compression is needed. HDBaseT is a pixel-perfect lossless video signal.
•HDBaseT solutions are more cost effective for smaller systems of up to 6 displays
•Will not work with other manufactures HDMI over IP solution
IP or HDBaseT Distribution?
Difference between different HDMI compression formats?
The Blustream Multicast products uses a proprietary HDMI over IP chipset and compression format.
There are many methods of HDMI video compression and it is important to understand the limitations and benefits of
each of these.
HDMI Compression Formats
Network switch requirements
It is advised that you use a network switch that is independent to your normal internet/network distribution (treat this product
as if it was a HDMI matrix).
The Network switch used should be a commercial use switch for performance, configuration options and reliability.
Blustream recommend using a Layer 3 managed switch for HDMI distribution systems
Differences between Layer 2 and Layer 3 Network switches
A Layer 2 switch does switching only. This means that it uses MAC addresses to switch the packets from a port to the destination
port (and only the destination port). It therefore maintains a MAC address table so that it can remember which ports have which
MAC address associated.
A Layer 3 switch is basically a switch that can perform routing functions in addition to switching. A Layer 3 switch has the same
features as a Layer 2 switch with additional management. For standard communication it uses the MAC address table. When
configured with additional VLAN it uses the IP routing table. A layer 3 switch can have an independant VLAN setup so that only
products within that VLAN can communicate, preventing unwanted traffic on the network.
Network Switch Requirements
Recommended brands of Network switches - not limited to any one brand
Network Switch Requirements
Network switch settings
There are several Network settings that your managed switch must support in order to distribute HDMI video reliably.
IGMP Snooping
IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic. The feature
allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to this flow of
traffic the switch maintains a map of which links need which IP multicast streams. Multicasts may be filtered from the
links which do not need them and thus controls which ports receive specific multicast traffic.
Jumbo Frames/Packets
Jumbo frames are Ethernet frames with more than 1500 bytes of payload. Conventionally, jumbo frames can carry up to
9000 bytes of payload, but variations exist and some care must be taken using the term. Many Gigabit Ethernet switches
can support jumbo frames.
MultiCast
Multicast (one-to-many or many-to-many distribution) is group communication where information is addressed to a
group of network devices simultaneously (Blustream IP100UHD-RX Receivers).
UniCast
Unicast transmission is the sending of information to a single network destination (one-to-one). This means only 1x
Blustream IP100UHD-RX can connect to a single IP100UHD-TX at a time.
Network Switch Requirements
IR, RS-232 & TCP control
The Blustream Multicast solution can be controlled using IR, RS-232 and TCP/IP commands.
The Blustream Multicast solution allows control of individual Transmitters and Receivers rather than controlling the system via
the Network switch as per our competitors. This has the following advantages:
• Faster switching
• Better traffic management
• Simpler installation
• Receivers and Transmitters can be connected to any port in the network switch and moved around without effecting control
• Simpler control Blustream products when system has multiple Ethernet switches.
The only disadvantage with this method of control is when the system is small (I.E – 4x4 system) in which control via the switch
is simpler.

IR control
TCP/IP control
System Control
IR & RS-232 pass-through
The Blustream Multicast solution can extend IR, RS-232 and TCP/IP commands from any IP100UHD product to another. This can
be used to control third party equipment located at any Blustream Transmitter or Receiver product.
With management of the control commands you can send a command to a single Blustream product - I.E control of a local
screen
It is also possible to send a single command to multiple Blustream products - I.E turning off all screens in a system
