2.1. First Steps
At first, the video network designer needs to decide what purpose needs to be satisfied with the video system - it will determine the size of the matrix and
the type of the network switch. The size of the matrix primarily depends on the number of inputs and outputs. When the designer knows that, the choosing
of the type of the switch can be started. The following table can help in that:
Required UBEX devices
Sources /
Business type
Destinations
Small business
up to 6 / 6
up to 12 / 12
Medium business
up to 22 / 24
up to 46 / 48
Corporate business
100+ / 100+

The Calculation
Let's see an example: the video network is designed for a small
business calculated with maximum 6 source and 6 destination devices.
The UBEX endpoint has 2 HDMI input ports and 2 HDMI output ports,
so the network needs 3 transmitters for the 6 inputs and 3 receivers
for the 6 outputs. It is 6 endpoints (the operation mode (TX or RX)
does not matter, the UBEX endpoint can be configured freely anytime
by the user), moreover the network needs one Matrix Management
Unit (UBEX-MMU-X200) to control the UBEX network.
The endpoints require two SFP+ ports in the switch per unit, in
summary, it is 12 ports in the case of six extenders. The video network
requires a 12-port 10G L3 fully managed switch to ensure the stable
data transmission for the UBEX system.
ATTENTION! The SFP+ ports must support 10 Gbps Ethernet!

Comparison table for video network designing
In the case of corporate business, the UBEX system gives an
opportunity building even an 1000x1000 video matrix. The transmitters
and the receivers can be variated dynamically because of the MMU is
able to handle it in real time. An asymmetric matrix can also be built
with UBEX endpoints, e.g. an 1x1000 or 1000x1 video system. The
possibilities are only limited by imagination.
The Matrix Management Unit requires one RJ45 or SFP ports with
1 GbE support to the network switch. The MMU does not transmit a
video, it controls the UBEX system only.
Bandwidth Management
The next challenge of the video network designing is the bandwidth
management. The next section describes how to calculate the
required bandwidth based on the video resolution and refresh rate on
the network and the general know-how of the bandwidth requirement
calculation.
