Is a multicast flow created by a transmitter alone a true statement?

A multicast flow is indeed created by a transmitter alone, which makes the statement true. In a Digital Audio Network Through Ethernet (DANTE) environment, when a multicast flow is initiated by a sender (transmitter), it sends audio data packets to a specific multicast address that can be received by multiple endpoints at once.

This operation is designed to be efficient, as it allows for one transmission to reach multiple receivers without having to create separate connections for each one. The critical aspect here is that the creation of the multicast stream is independent of the presence of receivers; the transmitter initiates the multicast flow by sending data packets to the multicast address, regardless of whether there are any receivers actively listening or registered to that address at the time.

This concept is vital because it highlights DANTE's capability to handle audio distributions effectively over an Ethernet network, featuring a point-to-multipoint transmission method that supports scalability for many devices.
