Planning for Video Streaming on IT Networks

NETWORKED AV
For the IT manager worried about “video” on his network think of Networked AV
not as “video-over-IP” but as “data-over-IP”. The “video” packets are data
packets just like any other packet on the network with the same protocols,
monitoring, control & security options as for other data packets.
The primary cost advantage with Networked AV comes when there is no cable
pulling at all – rather the house network with all its benefits is used to transmit
video and audio from anywhere to anywhere.

NETWORKED AV
A networked video stream can be thought of as items on a conveyor belt
being processed one at a time rather than in large batches
Bitrate is a measurement of how many
‘boxes’ per second are travelling down
the belt – network infrastructure is
defined by speed, in Megabits per
second (Mbps) or Gigabits per second
(Gbps)
Available bandwidth addresses how
many streams can be accommodated
simultaneously on the network

NETWORKED AV
Uncompressed video bandwidth requirement:
1080p30 1920x1080 30Hz 4:2:2 1 Gbps
1080p60 1920x1080 60Hz 4:2:0 1.5 Gbps
1080p30 1920x1080 30Hz 4:4:4 1.5 Gbps
1080p60 1920x1080 60Hz 4:2:2 2 Gbps
1080p60 1920x1080 60Hz 4:4:4 3 Gbps
2160p30 3840x2160 30Hz 4:2:2 4 Gbps
2160p60 3840x2160 60Hz 4:2:2 8 Gbps
2160p60 3840x2160 60Hz 4:4:4 12 Gbps
10 Gbps is the highest capacity Ethernet bandwidth available on CAT cable
10 Gbps CAT infrastructure is 10x the cost of 1 Gbps and doesn’t support POE
For economic and practical reasons
uncompressed video is largely
unsuited for video-over-IP

NETWORKED AV
Unicast point to point
• Example computer file to a printer
Broadcast point to every point
• Example device discovery
Multicast point to multiple points
• Example high-quality live video

NETWORKED AV
Multicast
One to many or many to many communication
Acts like broadcast if not properly controlled
Can be a great tool when managed correctly
Can disable a network when managed incorrectly!

NETWORKED AV
IGMP (Internet Group Management Protocol)
Groups ports based on multicast addresses.
Used to control multicast traffic within a single VLAN or
subnet.
Configured at the switch level – supported by all Layer 3
switches
IGMPv2 provides support for "low leave latency” which is a
reduction in the time it takes for members to leave and join
groups – required for some SVSI installations.

NETWORKED AV
Additional protocols supported by SVSI
SNMP
Provides for collecting and organizing information about managed
devices on IP networks and for modifying that information to change
device behavior.
LLDP
Used by network devices for advertising their identity, capabilities, and
neighbors on an local area network.
Gratuitous ARP
A broadcast packet sent to the network to maintain device authentication.

NETWORKED AV
Single 52 port network switch design (full backplane managed switch)
Each port has 1 Gbps bidirectional bandwidth, switch needs IGMP Querying &
Snooping
 52 i/o N1000 or N2000-4k with each encoder and decoder home run to
the switch (26 x 26, 16 x 36, 44 x 8 etc.)
 312 i/o N2000 at 150 Mbps with encoders and decoders ‘daisy-chained’
in groups of 6, each group connected to a single switch port.
 936 i/o N3000 at 5 Mbps with encoders and decoders ‘daisy-chained’ in
groups of 18, each group connected to a single switch port.

NETWORKED AV
Multiple network switch design

20 Gbps
links
 Uplinks determine total number of
possible sources (20 Gbps / stream
bandwidth)
 Encoders and decoders can be
attached to any port on any switch
 Any source can be routed to any
display or multiple displays on any
floor of the building
 One switch needs to be configured
for IGMP Querying, the additional
switches need IGMP Snooping
enabled

SVSI’s N-Series Applications

NETWORKED AV
Juniper Networks Campus, Sunnyvale, CA
World’s largest AV install on a fully converged network.
1200 x 800 decentralized and virtualized matrix switch.
On going expansion to new buildings on campus!

NETWORKED AV
Wynn Casino Sports Book, Las Vegas
The system has 66 inputs by 132 outputs.
Of the 64 inputs, 24 are designated for
traditional TV sources from satellite and cable
boxes. The remaining inputs are for horse race
track feeds. All TVs can display feeds from either
horse racing or sports. The large race and sports
area features 64 TV screens. There are 10
screens in the adjoining deli. The additional
outputs are used for preview monitors in the
control room, 34 feeds in the horse racing
carrels and six additional feeds in the poker
room.
“SVSI’s N-Able software allowed the engineers
to provide a spreadsheet to the installation
team. When the team loaded the spreadsheet
into the processor, the processor identified and
uploaded the configurations to the devices
based on the MAC addresses”.

NETWORKED AV
University of Little Rock, Arkansas
Nursing School
In the 22 clinical rooms patient care stations are
set up with a patient simulator manikin and
monitoring equipment. In each room two HD
camera feeds, microphone audio and patient
monitoring data (from PCs) are encoded real-
time by SVSI encoders for distribution to the
observation or meeting rooms and then
distributed throughout the facility and captured
by SVSI Network Video Recorders for archiving
and later playback.
“SVSi ‘s products provided a flexibility and
quality that I don’t believe could have been
met at this price point with other designs.”
Mark Chard, MS, CTS, DMC-D

NETWORKED AV
Havas World, Manhattan, NYC
Inside their new soaring glass play structure in
Hudson Square AV is everywhere, and nowhere.
It’s visually integrated into the architecture; it
runs on the main enterprise network; the
sources move freely through the open, glass-
filled building, across eight stories and 150
rooms. Nearly any source goes to nearly any
display; there’s no AV rack room. You can pop
your phone onto to a huddle display or pump
full HD onto a 25ft. canvas. You can send your
videoconference feed upstairs; you can monitor
your focus group from just about anywhere.
“The network is in all our jobs today. We see
it in our projects; our recent hires are
network engineers. We’re tying into a
massive IT structure, and AV has to flow from
that. It’s not designing screens on walls
anymore. If I fail at the IT objectives, I’ve
failed the client.”
