Virtual SmartPanel Settings

This view allows configuring Virtual SmartPanel settings such as STUN and TURN server settings that permit IP connectivity with devices connected to the Internet (Wide Area Network) through firewalls to support the operation of devices running the Virtual SmartPanel app.

Overview

System Management - Virtual SmartPanel Settings

STAGE is typically located behind a firewall (that uses Network Address Translation (NAT)) on your corporate network to protect it from bad-faith actors (hackers) on the public internet who could otherwise interfere with the normal operation of your networked equipment by trying to send commands to your software, with harmful effects.

STAGE communicates with software such as the Virtual SmartPanel (VSP), where it is understood that users will use the public internet in order to interact with STAGE. The following techniques allow STAGE and Virtual SmartPanel to communicate through the NAT to allow Peer-to-Peer (P2P) communication without compromising network security:

STUN: Session Traversal Utilities for NAT; a network protocol that allows interactive UDP flows to pass through a NAT.
TURN: Traversal Using Relays around NAT; a network protocol that allows STAGE (located behind a firewall) to control the operation of a relay server, that in turn, exchanges packets with Virtual SmartPanel, for example. TURN is used when a P2P connection cannot be established with STUN.

Both STUN and TURN require a server exposed to the internet with the STUN / TURN software running on it. The white paper with more detailed information can be found in the follwing chapter: Riedel STAGE™ & Virtual SmartPanel® – How to Implement STUN and TURN

How to use the Virtual SmartPanel Settings

The System Administrator or Technical Administrator access level is required.

Adding a STUN Server

Select the STUN tab.
Click on the Add button.
Set the URL/IP for the STUN service in the following format stun:[FQDN/IP Address]:[Port]. Ensure to include stun: at the start of the URL/IP.
Click Save.

The STUN entry has now been added to the Riedel STAGE system and is available for use.

Adding a TURN Server

Select the STUN tab.
Click on the Add button.
Set the URL/IP for the TURN service in the following format turn:[FQDN/IP Address]:[Port]. Ensure to include turn: at the start of the URL/IP.
Optional: Set the required username and password for the TURN service.
Click Save.

The TURN entry has now been added to the Riedel STAGE system and is available for use.

STUN/TURN

Password
	Click to add a STUN/TURN service.
URL	Shows the URL or IP address of the STUN/TURN service.
Username	Optinal for TURN servers: Shows the username and Password of the the TURN service.

Setup

URL

Enter the URL or IP address of the STUN/TURN service.

Buttons

Click on Delete to delete the selected service.

Click on Cancel to discard changes.

Click Save to apply changes.

Media Settings

AES67

Codec	Selection of the Bit resolution. (L16, L24)
Packet Time	Packet time is the real-time duration of media data in a packet. (125, 250, 333 or 1000 µs)
Receive Buffer	Selection of the size of the AES67 receive buffer to adapt the expected delay of connected panels. The default buffer is 8 × Packet Time. (3 ... 112 x packets)
Preferred Sync Mode	In Strict mode audio packets will be discarded if the PTP timestamp is missing or invalid. Hence only audio signals are output if they are transmitted in a PTP synchronized network. In Adaptive mode audio packets without or with invalid PTP timestamps are processed and output, hence this mode can be used in networks without PTP synchronization. This may lead to increased delay and jitter.
