Media 
Sequencer
8580
8594
For clients connecting to the Media Sequencer. 
8580 is specifically used when connecting over 
http using the REST interface.
Viz Video Hub 8080 Used for sending keyframes (service: ardok).
Viz Gateway 10001
10002
10540
10541
For DB notification events.
For Viz Gateway controller clients.
For MOS object updates.
For MOS playlist updates.
Viz World Server 10100
10200
10100 (TCP) is a Server Allocator listener port for 
Viz World Client connections, and is only used in 
order for clients to get connection details about 
Viz World Server(s). The first client connection will 
always be diverted to port 102. In case of multiple 
server instances port numbers are assigned 
according to a predefined schema (i.e. 10101, 
10102 for server instance 2 and 3 and so on). In 
case there is no Server Allocator, Viz World Server 
will itself switch to port 102.
10100 (UDP) is a Viz World Server listener port for 
Server Allocator communication.
10200 (UDP) is a Server Allocator listener port for 
Viz World Server communication.
Both UDP ports are internal ports used between 
the servers.
For more information, please see the Viz World 
Client and Server 11.1 User’s Guide and later. See 
also Vizrt Maps.
Viz Content 
Pilot
10640 Used by Viz Gateway to establish a connection to 
Viz Content Pilot in order to send and receive 
updates on MOS messages (e.g. elements and 
playlists).
Viz Engine 14300 Alternative port used to avoid conflicts with port 
6100 (e.g. when using Viz Multiplexer). Port 6100 
is normally used by renderers that are on air, 
hence, it is (e.g. when running Viz Content Pilot 
version 4 or Viz NLE Plugin towards Viz 2.x) 
recommended to use another port.
Port 14300 is an optional port. The default 6100 
may also be used if the renderer is not used on air.
Viz Graphics 
Hub
19392-
19396
Ports in use when connecting to different Viz 
Graphics Hub components.
Viz Connection 
Broker
21098 Connection to the Viz Connection Broker 
configuration interface (e.g. http://
localhost:21098/)
