Introduction
Crestron® DM NVX™ network AV encoders/decoders transport ultra high-definition 4K
video with 60 Hz frame rates and 4:4:4 color sampling over standard Gigabit Ethernet.
Support for High Dynamic Range (HDR) video and HDCP 2.2 ensures high picture quality
and compatibility with a variety of media sources. Using Pixel Perfect Processing
technology, a video signal is encoded and decoded to achieve imperceptible end-to-end
latency of less than 1 frame.
DM-NVX-E30(C) devices consist of the DM-NVX-E30 surface-mountable endpoint
and the DM-NVX-E30C card, which function as encoders (transmitters) only.
DM-NVX-D30(C) devices consist of the DM-NVX-D30 surface-mountable endpoint and
the DM-NVX-D30C card, which function as decoders (receivers) only. Compact in design,
the DM-NVX-E30 and DM-NVX-D30 are designed to fit in various locations, for example,
behind a flat panel display. The DM-NVX-E30C and DM-NVX-D30C are designed to
occupy the DMF-CI-8 card chassis.
NOTES:
• The DM-NVX-D30 and DM-NVX-D30C do not support scaling.
• DM-NVX-E30(C) encoders and DM-NVX-D30(C) decoders are compatible with
DM-NVX-350(C), DM-NVX-351(C), and DM-NVX-352(C) encoders/decoders.
If DM-NVX-E30(C) encoders are used with DM-NVX-35x(C) devices, the
DM-NVX-35x(C) devices must be in Receiver mode. If DM-NVX-D30(C) decoders are
used with DM-NVX-35x(C) devices, the DM-NVX-35x(C) devices must be in
Transmitter mode.

DM-NVX-D30C only.
Subscription of a DM NVX encoder to a DM NVX decoder sets up Real Time Streaming
Protocol (RTSP) negotiation between the DM NVX decoder and the DM NVX encoder.
When a stream is routed, the DM NVX decoder performs the Internet Group
Management Protocol (IGMP) join, which causes the decoder to join the multicast group
of the encoder. A maximum of 64 encoders can be subscribed to a single decoder.
To configure subscriptions, use the web interface or SIMPL Windows as discussed in the
following sections.
Using the Web Interface
Configure subscriptions on the Subscriptions and Routing pages:
1. On the Subscriptions page, do either of the following:
a. In the Subscribed Streams section, manually add each encoder that is to be
subscribed to the decoder or load one or more existing subscription lists
(*.xml). The default filename of the subscription list is subscription.xml.
NOTE: Subscribed transmitters can be reordered in the list. To do so, click the
encoder that is to be reordered in the list, and then click the up arrow
( ) or the down arrow ( ) until the encoder appears in the desired
location in the list.

HDCP 2.2 Compliance
DM NVX devices are HDCP 2.2 compliant. HDCP 2.2, commonly referred to as HDCP 2, is
the next generation of HDCP (High-Definition Content Protection). Note the following
about HDCP 2:
• Compared to HDCP 1, HDCP 2 brings a higher level of cryptographic protection
to HDMI technology.
• HDCP 2 is not HDMI 2. It is possible to have a system built on HDCP 1 and
HDMI 2 or on HDCP 2 and HDMI 2.
• Although not all 4K content requires HDCP 2, most 4K consumer video content
does require HDCP 2.
• Any product that supports HDCP 2 also supports HDCP 1.
• HDCP matters only when the source demands HDCP. If the source demands
HDCP 2, then every device in the signal path must support HDCP 2.
• There are no issues related to HDCP 2 and cabling—all cables are compatible.

IGMP Snooping
A DM NVX device sends IGMP join and leave messages.
NOTE: DM NVX devices support IGMPv2 and IGMPv3 only. IGMPv1 is not supported.
The IGMP snooping support version (v2 or v3) is configurable in the web interface.
The
Network Interface section of the Network page allows the desired version to be
selected. The default setting is
Network Page - Network Interface
NOTE: When a different IGMP snooping support version is selected, the DM NVX device
must be rebooted in order for the change to take effect.
The network switch port that connects to a DM NVX device must be enabled with
IGMPv2 or IGMPv3 snooping to prevent the switch from flooding the multicast
destination address traffic to all other connected ports. The multicast destination
address that is configured for the DM NVX device must be within the range of qualified
addresses. An upstream device such as a layer 3 router or switch periodically sends the
IGMP General Query messages to hosts in order to maintain group membership state
information. These queries can be either general or group-specific queries. The host
responds to queries with IGMP membership reports. The host running IGMPv2 or IGMPv3
may also send a Leave Group message to routers or switches in order to withdraw from
the group.
v2.
NOTES:
• DM NVX devices do not support random-timer and source-specific queries.
• As a host, a DM NVX device configured for support of IGMPv3 is compatible with a
network switch (IGMP querier) that is configured for IGMPv2.
IGMP snooping switches build forwarding lists by listening for and, in some cases,
intercepting IGMP messages. Although the software processing the IGMP messages may
maintain state information based on the full IP group addresses, the forwarding tables
are typically mapped to link layer addresses as shown in the following example.
Example of Forwarding Table
MULTICAST MAC ADDRESS MEMBER PORTS
01-00-5E-00-00-01 2, 7
01-00-5E-01-02-03 1, 2, 3, 7
01-00-5E-23-E2-05 1, 4
Because only the least significant 23 bits of the IP address are mapped to Ethernet
addresses (RFC 1112), there is a loss of information when forwarding solely on the
destination MAC address. For example, IP addresses 224.0.0.123 and 239.128.0.123 and
similar IP multicast addresses all map to MAC address 01-00-5e-00-00-7b for Ethernet.
Product Manual – DOC. 8425A DM-NVX-E30(C)/DM-NVX-D30(C) Encoders/Decoders • 23
Page 28
As a result, IGMP snooping switches may collapse IP multicast group memberships into a
single Ethernet multicast membership group.
In addition to building and maintaining lists of multicast group memberships, the
snooping switch must also maintain a list of multicast routers. When multicast packets
are forwarded, the packets should be forwarded not only on ports that have expressed
joins using IGMP but also on ports to which multicast routers are attached.
NOTES:
• Do not assign reserved multicast IP addresses to a DM NVX device for streaming.
For additional information, go to
https://www.iana.org/assignments/multicast-addresses/multicast-addresses.txt
.
• Multicast collision is a concern with IPv4. For example, multicast IPv4 addresses
224.8.7.6 and 229.136.7.6 translate to the same MAC address (01:00:5E:08:07:06).
The following items provide recommendations for configuration of a network switch for
IGMP snooping:
• Set the IGMP query interval to 60 seconds or 125 seconds. The recommended
setting is the default setting of the network switch.
• For good network performance, ensure that there is only one IGMP querier in the
network.
• Set IGMP snooping to v2 or v3.
• Enable IGMP snooping globally as well as for each specific VLAN for DM NVX
connected ports.
• Configure the network switch to drop unknown multicast packets.
• If the network switch supports IGMP fast leave, enable the configuration at the
port, global, or VLAN level.
• If the network switch supports PIM snooping, enable the configuration to prevent
flooding IP multicast traffic toward multicast router (mrouter) ports.
