Once a processing blade is part of the operational network, its streaming connections can be managed from HOME's 'Stream Routing' page.

The operation of this page is identical for all devices on the HOME network, and so the same steps apply to all devices known to HOME. 

For .edge, the main points are:

  • The senders and receivers are pre-defined, where each one handles the three essence types of an SDI I/O: 1 x Video, 4 x Audio, 1 Meta(data).
  • The essences can be routed as a group (Video, Audio & Meta) or individually (by revealing the flows).

'Stream Routing' Overview

The 'Stream Routing' page manages all of the network's streaming connections.

From here, you can connect a sender to a receiver, interrogate and lock existing connections, disable the sending streams and view/edit the stream configuration parameters.

Sources and Destinations

The page lists all available IP senders on the left (as Sources) and IP receivers on the right (as Destinations).

  • For each source and destination, there are two parts to the label: <device>/<sender> or <device>/<receiver>.
  • The icons in the Essence column describe the type of flow(s): Video, Audio, Metadata and/or GPIO.
  • If a source or destination handles more than one flow, then an arrow appears beside its label. Click on the arrow to show (or hide) the individual flows.
  • Once a source is connected, a number appears in the "source used" column. This indicates the number of times the source is used. i.e. the number of connections made.
  • Once a destination is connected, the "Connected Source" field shows the label of the connected stream.

Why is my device missing?

If your device or app is missing from the source and destination lists, check the following points:
  • Are any Filters applied (to restrict the view)?
  • Is the device online? Go back to the 'Devices' list and check the Status.
  • For HOME Apps, is the app running and healthy? Open the 'Device → General' settings page and check the Lifecycle information.
  • Are the senders and receivers configured? Open the 'Device → Senders/Receivers' page to check the available flows.

'Stream Routing' Operations

The following operations are possible:

  • Make or break connections - using Connect and Disconnect.
  • Interrogate connections - using Show Destinations (for a sender) and the "Connected Source" field (for a receiver).
  • Lock connections - using the Lock option (for a receiver).
  • Disable sending streams - using Disable (for a sender).
  • View (or edit) the stream configuration parameters - via the Info dialog (for a sender or receiver).
  • View (or edit) the audio channel mappings - via the I/O Routing page (for a sender or receiver).

Connecting Streams (Quick Start)

To make a connection, select a source (on the left) and a destination (on the right); then click on Connect.

  • A dotted (preview) line appears when a valid connection is prepared.
  • This changes to a solid line once the source(s) and destination(s) are connected.

Connections can be made between individual or groups of flows, and for multiple sources and destinations. This is explained in more detail here. For now, it is useful to know that:

  • If a source or destination handles more than one flow, then the flows are grouped so that they can be connected (or disconnected) in one operation. For example, select an SDI In, SDI Out and Connect (to connect Video to Video, Audio to Audio and Metadata to Metadata).
  • If there is more than one possible match, then the sender(s) and receiver(s) are connected consecutively. For example: Audio 1 to Audio 1, Audio 2 to Audio 2, and so on.
  • At any time, you can expand a group to reveal its flows. For example, to deviate from the default routing and connect a different audio sender.

How is the Stream Routing saved?

The stream routing (for all devices in the HOME network) is stored automatically on the HOME server(s) whenever a change is made.

If the HOME system restarts, then the configuration is re-instated once the server(s) reboot.

If an end device restarts, or is disconnected, then any streaming connections to and from the device are lost. However, the connections are still prepared. This means that as soon as the device comes back online, its streaming connections are re-established.

If you wish to backup the current configuration for the system's physical devices, then this can be done by creating a HOME snapshot. Snapshots can be created either globally (for all online devices) or partially (for selected devices). For more information, please see HOME - Snapshots.
