In the diagram above one ST 2110 stream has been subscribed to by 6 outputs but the bandwidth required by
the network switch bandwidth is for one stream only.
PTP Grandmaster
In order to maintain timing you need a Precision Time Protocol grandmaster or PTP clock
connected to the switch. Similar to using genlock via a master sync generator for synced SDI
connections, PTP generates accurate timing and frequency to maintain the packets of ST 2110
data over the network. This ensures that all streams are synchronized.
The PTP clock is the grandmaster and all other IP video devices should be set as the 'follower'
to ensure no timing conflicts can occur. For more information on setting your Blackmagic 2110 IP
Converter 3x3G as a follower, refer to the 'setup menu' later in this manual.
NMOS Controller
Traditional SDI connections send signals in one direction with video, audio and ancillary data
such as timecode and closed captions embedded in the one signal.
With ST 2110, the signal is split into video, audio and ancillary data elementary streams. This
provides flexibility to route video, audio or ancillary data streams independently whilst keeping
each essence stream synchronized so they can be brought back together at the end of
the workflow.
This is all achieved through timing. But how does one converter know what the other converter
is doing? This is where the Networked Media Open Specifications, or NMOS for short, is
important.
NMOS is a group of specifications that direct the flow of traffic in an IP network and manage
communications between all the endpoint devices. Once a hardware or software NMOS
controller is connected to the network you can route any or all of the elementary streams to any
endpoint device on the network.
