A flow is independent of the transport protocol. For example, 48kHz LPCM audio is a flow; AES67 is one type of
stream which can carry the flow.
Flows cannot generally be passed around natively, and need to be encapsulated in a stream. Flows from the same
source are considered “editorially equivalent”, but may be encoded differently.
Receiver
An element within a device that receives exactly one stream, which contains one flow from a network.
Sender
An element within a device which presents exactly one flow, packaged as a stream onto a network.
Stream
One flow, encapsulated within a transport protocol (e.g. SMPTE ST 2110-30 Audio (AES67)).
Network Stream Group
A network stream group allows you to create a grouping of streams on the network into a unit that can be mapped to
a Watermark Encoder channel. Network stream groups are required when:
• the output has more channels than a stream on the network and the user wants to drive all channels;
• the user wants to perform complicated audio shuffling
