Unmanaged Host Configuration

Overview

An unmanaged host represents in STAGE a device that STAGE is unable to configure or control. However, this host can send and receive AES67 audio stream(s). Essentially it is a proxy in STAGE for this device.

Depending on the selected item in the Settings section Untitled-1-20251202-195927.png , the available parameters on the right-hand section Number_2_red.png changes.

General Settings

Main

Name

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

Description

New Producers can be added manually or by using an SDP file.

Name

Name of the Producer.

Main

Displays the Primary Multicast Group and Port.

Redundant

If Redundancy is enabled, the Secondary Multicast Group and Port are displayed.

General

Name

This host will be identified throughout STAGE by this name.

Producer Type

Shows the audio stream type:

Audio (AES67): The stream uses the AES67 audio over IP standard.

Redundancy

When the host supports SMPTE ST 2022-7 network redundancy, this option can be enabled or disabled.

Set: SMPTE ST 2022-7 network redundancy is enabled.

Cleared: Only the primary interface is used for the audio stream.

Primary/Secondary Sender Settings

Primary (Main) Interface

Set the Ethernet interface that STAGE uses:

  • When the host does not support SMPTE ST 2022-7 network redundancy, this is the network on which the host’s media interface is connected.

  • When the host supports SMPTE ST 2022-7 network redundancy, this is the RED network on which the host’s primary media interface is connected.

Secondary (Redundant) Interface

Set the Ethernet interface that STAGE uses when the host supports SMPTE ST 2022-7 network redundancy, this is the BLUE network on which the host’s secondary media interface is connected.

Source IP

Shows the host’s IP address for the source media stream.

Multicast Group / Port

Set the host’s multicast destination IP address.

Audio Sender Settings

Sampling Rate

Set this WebRTC Gateway’s operating audio sampling data rate.
44.1 kHz, 48 kHz, or 96 kHz.

Chanel Count

Set the number of supported audio channels.

Audio Format

Set the audio sampling bit depth.

L16: Linear PCM 16-bit depth.

L24: Linear PCM 24-bit depth.

L32: Linear PCM 32-bit depth.

Packet Time

Set the duration of the audio data captured and transmitted in a single digital packet over a network. See https://en.wikipedia.org/wiki/AES67 for more information. Select one of: 125 μs, 250 μs, 333 μs, 500μs, 1 ms, 2 ms, or 4 ms.

Stream Settings

RTP Payload Type

Set the values for dynamically assigned RTP Payload Type (RFC3550) for the audio stream in the range of 96 to 127.
Values between 0 and 95 should not be used as they are either reserved or unassigned. The default value is: 98 for AES67 audio.

Multicast TTL

Set the initial TTL value in sent packets. This sets the number of hops through network routers that are allowed before the packet is discarded. When a router receives a multicast packet, it decrements the packet’s TTL value by one. If the packet’s TTL is less than the minimum threshold set on the router’s interface, the packet is discarded.

This setting tunes the network to prevent multicast packets from circulating indefinitely, to help contain multicast traffic within specific network segments.
