General Settings

Main

Name

Set a friendly name for this host. This host will be identified throughout STAGE by this name.

Description

Set a meaningful description for this host.

Version

Shows the WebRTC Gateway’s software version.

Date Added

Shows the date and time when the host was added to STAGE.

PTP

Preferred Interface

Set the Ethernet port the server is to prioritize for use to communicate on the network.

Profile Type

Set the PTP profile to use as a preset configuration for the below PTP settings.

Custom: Freely set the PTP parameter values.
AES67-Media: Use the PTP preset values for AES67 media signal type.
ST2059-2: Use the PTP preset values for SMPTE ST 2059-2 signal type.
AES-R16: Use the PTP preset values for AES-R16 signal type.
IEEE1588 Default: Use the PTP preset values for IEEE1588 signal type.

PTP Domain

Set the domain to use for this WebRTC Gateway’s PTP clock.
PTP domains allow you to use multiple independent PTP clocking subdomains on a single network.

Priority 1

Set the Priority-1 of the PTP source.
Default PTP Priority 1: 128, Range: 0...255

Priority 2

Set the Priority-2 of the PTP source.
The PTP Server-Clock of AES67 cards have a higher priority than the PTP Server-Clock for panels. The highest possible priority for panels is 126. Thus the default setting of AES67 cards is increased to 120.
Default PTP Priority 2: 120, Range: 0...255

Announce Interval

Set the base-2 logarithm of seconds of the interval of PTP announce messages.
Default Announce Interval: 1, Range: -3...4

Announce Timeout

Set the timeout for the receipt of the aforementioned messages.
Default Announce Receipt Timeout: 3, Range: 2...10

Sync Interval

Set the base-2 logarithm of seconds of the interval of PTP sync messages.
Default Sync Interval: 0, Range: -7...1

Delay Request Interval

Set the base-2 logarithm of seconds of the interval of PTP delay request messages.
Default Delay Request Interval: 0, Range: -7...5

Transport Type

Set the transport protocol used for PTP packets.

Delay Mechanism

Set the delay mechanism in the network: E2E (End to End), P2P (Peer to Peer) or Auto.

Slave Only

Set if this WebRTC Gateway is to be a PTP TimeReceiver (enabled) or a PTP TimeTransmitter (disabled).

Processing

Maximum Connectable Clients

Set the maximum number of clients this WebRTC Gateway is to support. Default: 100, Range: 1...1000

Opus Packet Time

Set the real-time duration for the transmission of audio data packets.

Default value: 20 ms Range: 2, 5, 10, 20, 40, 60, 120 ms

Opus Receive Buffer

Set the minimum Receive Buffer size for the WebRTC (Opus) service.

This works in conjunction with the Additional Dynamic Receive Buffer parameter to define a dynamically sized buffer range. For example, when the buffer size parameters are set as follows:

  • Opus Receive Buffer: 40ms

  • Additional Dynamic Receive Buffer: 40ms

This means the receive buffer is sized for 40ms of delay and up to a total 80ms of delay when needed.

Additional Dynamic Receive Buffer

Set the dynamically sized extra buffer range, beyond the Opus Receive Buffer size for the WebRTC (Opus) service.

Actions

Reboot

Click to reboot the WebRTC Gateway server.

Network Interfaces

Network Scope

Network Scope

Set the type of traffic to exchange on this interface. See also chapter Network Architecture for more information about the different network types used by STAGE. See also chapter Network Scopes for more information about how to configure the different network scopes used by STAGE.

  • image-20251218-214928.png Management

  • image-20251218-215027.png Media Main: For SMPTE ST 2022-7 network redundancy, this the RED network on which SMPTE ST 2110 streams are sent.

  • image-20251218-215055.png Media Redundant: For SMPTE ST 2022-7 network redundancy, this the BLUE network on which SMPTE ST 2110 streams are sent.

  • Any other Network Scope that has been added to STAGE.

When two network interfaces are set to the same network scope, STAGE assumes that the network is capable of routing packets between those interfaces. That is, if you have one sender on a network scope and a receiver on the same network scope, then the network will pass multicast traffic flows between these hosts. This setting must represent the real world network topography for each host.

Interface Capabilities

Select the types of network traffic that this network interface provides access to.

ICE Candidate: Specifies the network interface for WebRTC use.
Media: Set to use this network interface for SMPTE ST 2110 audio streams.
PTP: Specifies the network interface for PTP clock signals.
Control: Specifies the interface for system control signals. For example, for NMOS connections to devices.

IPv4 / IPv6

Enabled

Set to enable this network addressing protocol on this network interface.

DHCP

Set to enable the use of DHCP for this network interface.

When your network has a working DHCP server, set this option so that this network interface automatically negotiates and acquires its dynamically allocated Ethernet interface parameters (IP Address, Network Mask, and Gateway) from the network. In this situation, it is not necessary to set the below IP Address, Network Mask, and Gateway parameters.


Add new address

Click to add a new:

  • IP address and network mask to this network interface.

  • IP address for a network’s DNS server.


IP Address

When the DHCP parameter is disabled, double-click the value to set the IP address for this network interface.


Network Mask

When the DHCP parameter is disabled, double-click the value to set the network mask for the associated IP address.


DNS Server Address

When the DHCP parameter is disabled, double-click the value to set the IP address for your network’s DNS server.


Default Gateway

When the DHCP parameter is disabled, double-click the value to set the IP address for the local network’s router

Auto (IPv6): Double-click to manually set the IP address for the local network’s router.
