AT-OMNI-512 7
The Atlona AT-OMNI-512 is a networked AV encoder with two independent channels of encoding for two HDMI
sources up to 4K/60 4:4:4 and HDR (High Dynamic Range), plus embedded audio and RS-232 or IR control pass-
through. OmniStream is designed for high performance, exible distribution of AV over standard, o-the-shelf
Gigabit Ethernet switches in commercial audiovisual applications. The OMNI-512 features the advanced VCx™
codec which delivers 4K/60 4:4:4 video from encode to decode, with artifact-free presentation of computer-
generated content and fast-motion video, and ultra-low latency less than one frame. This dual-channel encoder is
housed in a half-width rack enclosure with front-to-back air ow, and is ideal for high-density, compact installation in
a centralized equipment location.

Introduction to OmniStream
OmniStream products are similar in principle to matrix switch endpoints: A/V signals are sent from one point
(transmitter) to another point (receiver) over category cable. However, OmniStream stands apart from matrix
switchers, in that it is an IP-based solution, allowing this data to be sent over a standard IP network. In addition,
these endpoints are referred to as encoders and decoders. Encoders act as “transmitters” and decoders act as
“receivers”.
IP Address Assignment
Figure 1.1 below, shows an encoder and a decoder, connected through a network switch. As with all network
devices, both the encoder and decoder must have unique IP addresses. OmniStream encoders and decoders are
DHCP-enabled, by default. This means that when the encoder/decoder is connected to the network, and a DHCP
server is available, the encoder/decoder will automatically be assigned an IP address. If no DHCP server is available,
then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx/16. OmniStream devices
can also be assigned a static IP address, if necessary. Static IP addressing will be covered in a later section.
Figure 1.1 - An encoder and decoder on a network, with assigned IP addresses.
DEFINITIONS
Encoder – Compresses source signals before sending them out over a network environment.
Decoder – Receives and decompresses signals from an encoder and sends them to an output
device, such as a display or other sink device.
IP Address – A unique numerical label that is assigned to each device connected to a network.

Introduction to OmniStream
Network Bandwidth and OmniStream Compression
When sending video and audio over a network, the available bandwidth needs to be managed. Gigabit Ethernet
switches are very common and can take advantage of installed Category 5e cable. 10-Gigabit Ethernet switches
are available, but are more expensive per port and require Category 6A cable or better. The chart below shows
uncompressed data rates for common resolutions. These data rates exceed the available bandwidth of Gigabit
Ethernet, but using the compression technology in OmniStream, this video can be streamed over cost-eective
Gigabit networks.
Resolution Data Rate*
1920 x 1080p 30 Hz 2.2 Gbps
1920 x 1080p 60 Hz 4.5 Gbps
3840 x 2160p 30 Hz 8.9 Gbps
3840 x 2160p 60 Hz 17.8 Gbps
OmniStream compresses the source data at the encoder, before it is sent out over the network. This process is
known as encoding. OmniStream uses VCx and VC-2 compression, which are intermediate compression schemes
and oer lower latency and higher video delity than an interframe compression scheme, such as H.264 or H.265.
Interframe codecs are typically used by cable or internet providers and use very aggressive bit rates (low bandwidth)
with high latency (delay), which results in lag. VCx and VC-2 provide both high quality (high bit rates) and very low-
latency for a much more desirable viewing experience.
* Data rate is shown without compression.
Streams
Sessions
The term stream is used throughout this manual, to describe the dierent types of signals that are transmitted over a
network. For example, if a blu-ray player is connected to an encoder, both video and audio are sent to the encoder
over an HDMI cable. The term video stream is used to identify the video portion of a signal and audio stream
identies the audio portion of the signal.
A session is a way of organizing audio and video streams. The session identies each stream with a unique multicast
IP address and UDP port assignment. This provides an address to determine where the package of audio and video
should be sent. Table 1.1 illustrates how a session encapsulates a video and audio stream.
NOTE: Sessions are not limited to only video and audio streams. Control data, such as IR and
RS-232, as well as AES67 audio, can also be contained within a session. These topics will be
covered in a later chapter.

Subscribing to a Stream
To receive information from an encoder, the decoder must subscribe to the multicast IP address and UDP port of
the stream(s). Note that the decoder does not subscribe to the session, but to the stream(s) within the session.
The process of subscribing is similar to changing the channel on a Set-Top Box. For example, in order to view the
content on channel 213, the Set-Top Box must be set to channel 213. Similarly, for a decoder to subscribe to an
encoder stream, the multicast IP address and UDP port settings on the decoder must be set to the same values as
the encoder to which it is subscribed. Note that the management IP address of a unit is dierent than its multicast IP
address.
Figure 1.3 shows two encoders and a single decoder connected to a network switch. Decoder “C” is subscribed to
encoder “A”, since the multicast IP addresses and UDP port numbers for both video and audio are set to the same
values as encoder “A”.
