Putting SAME Under Northbound Control | Riedel Online Help Center

Introduction

The SAME DSP Engine Host Configuration has a Direct Control Mode that:

Exposes static senders and receivers to external systems using AMWA NMOS IS-04 and IS-05.
- Registered Device’s audio signals.
- Processing Plugins and Mixers audio signals.
Provides parametric control and operational User Interfaces for processing Plugins and Mixers through the STAGE northbound GRPC Northbound API. See SAME_ STAGE Northbound API for more information about this API.
- Through this API, the URLs for plugins and mixer Web interfaces are available, allowing you to integrate these screens into your Broadcast Control System (BCS).
- The SAME DSP Engine uses the STAGE Northbound API to receive control commands and to send status updates.

For example, a SAME DSP Engine can be used in a static way to provide plain processing resources to an environment managed by a BCS and/or SDN. If parametric control from a BCS is required, the BCS must implement the STAGE GRPC Northbound API accordingly.

When the SAME DSP Engine is in Direct Control Mode:

It does not support a user being able to run Jobs and configure Volumes. It is dedicated to being operated by the BCS only.
The SAME DSP Engine and integrated Riedel Devices are not added or configured to the BCS directly. Instead they are discovered in STAGE using proprietary discovery protocols. Once registered in the SAME DSP Engine, STAGE will expose these devices and the SAME DSP Engine as NMOS Devices in a SAME DSP Engine NMOS Registry Node through IS-04. Each NMOS Device will have senders and receivers representing the actual senders and receivers on the device or engine.

AMWA NMOS capable devices are discovered directly by the BCS through the NMOS Registry.
Dynamically created Senders and Receivers are exposed by this SAME DSP Engine to the BCS. will be made available on the BCS northbound routing interface.
Connection requests from this SAME DSP Engine will always be sent to the BCS northbound routing interface.
The BCS will execute connection requests from SAME DSP Engine Northbound routing interface by reconfiguring receivers (including SAME DSP Engine managed Riedel devices).

Enabling the STAGE Northbound API and AMWA MNOS IS-04 and IS-05

To use STAGE Northbound APIs, you must first enable them in System Management.

For more information about System Management > System Configuration, see SAME_ System Management.

Enabling Northbound AMWA MNOS IS-04 and IS-05

When this option is enabled, STAGE will act as an AMWA NMOS IS-04 / IS-05 Node. Hosts that are enabled as Direct Control Mode (see below) will register itself to the NMOS Registry configured here.

Enable NMOS Registration	Set to register this STAGE instance as an AMWA NMOS IS-04 / IS-05 Node. For this, Direct Control Mode (see below) must be enabled.
Static Registry Protocol Http	Set the communication security level used by the AMWA NMOS registry. Http: Communication is in clear text. Https: Communication with the NMOS Registry is encrypted.
Static IS-04 Registry Host	Set the AMWA NMOS Registry’s IP address.

Create Senders / Receivers

In Direct Control Mode, you create Senders and Receivers audio streams. The SAME DSP Engine registers these streams in the AMWA NMOS Registry.

Proceed as follows:

Click Create Sender / Create Receiver.
Configure the parameters shown below.
Click Create.

Parameter		Applies to		Description
Parameter		Sender	Receiver	Description
Label	Label			Set a friendly name for this host. This host will be identified throughout STAGE and NMOS by this name.
Amount	Amount			Set the number of Senders / Receivers to create.
Network Interface Selection	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.
Network Interface Selection	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.
Destination Address Settings	Unicast / Multicast			Set the packet transmission method. Unicast: Use one-to-one connection to stream content. Multicast: Use one-to-many connections to stream content. Senders and receivers support the entire range of multicast IP addresses from `224.0.2.0` to `239.255.255.255`, as per JT-NM TR-1001-1 requirements. Nevertheless, certain multicast IP addresses in the range from `224.0.2.0` to `239.255.255.255` are subject to assignments and allocations, committing them to other purposes as per IETF RFC 5771.
	Main IP			Set the IP address for this stream.
	Main Port			Set the port number for this stream.
Source Address Settings	Auto / Manual			Auto: Set to enable to automatic use the Main IP address as the stream's source IP address. This overrides the Main IP setting. Manual: Use the Main IP setting.
	Main IP			Set the IP address to use as the stream's source IP address when Auto / Manual is set to Manual.
	Main IP			Set the IP address to use as the stream's source IP address.
Stream Settings	Channels			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.
	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.
Additional Settings	Time to Live (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.
	DSCP			Set the packet’s quality of service level to allow the network to prioritize packet traffic. See https://en.wikipedia.org/wiki/Differentiated_services.
	Receiver Buffer (ms)			Set the receive buffer size. The buffer size establishes the device’s resistance to network jitter and packet delay.

Sender / Receiver Configuration Settings

The Sender or Receiver settings can be changed. Proceed as follows:

Mixers / Plugins Tab

Configure the mixers and plugins that the BMS can automate, by for example, creating Snapshots of a setup that can be recalled.

Adding Mixers and Plugins for use with Northbound Control

When you add Mixers and Plugins to the SAME DSP Engine in the Volume Activation tab, they become available as a resource to be used under Northbound Control. To add Mixers and Plugins to the SAME DSP Engine, see SAME_ SAME DSP-Engine Volume Activation Tab.

Add Mixer and Plugin Presets and Snapshots

The configuration of certain SAME Applications can be memorized as a preset for instant recall. Presets can be used by automation to setup a plugin into a known configuration state as required.

Click a mixer or plugin listed in the Mixers / Plugins tab. This opens the mixer or plugin.
Configure the mixer or plugin as needed.
Create a preset / snapshot. To create a preset, see SAME_ SAME Application Preset Configuration.
The preset / snapshot can be invoked through the STAGE Northbound API.

For more information about Presets and Snapshots, see STAGE Northbound API #Presets, #Snapshots, and #Using-Snapshots-and-Presets.

Opening a Mixer’s / Plugin’s Web Interface

Through the STAGE Northbound API, the URLs for plugins and mixer Web interfaces are available, allowing you to integrate these screens into your Broadcast Control System (BCS). See STAGE Northbound API for more information.
