Multi-Unicast Programs

A multi-unicast program (also known as multiple unicast) can transmit a single audio stream with common connection settings to a number of different destinations. All connections that are part of a multi-unicast connection will automatically attempt to reconnect if they are terminated remotely.

 

Multi-unicasts are useful for distributing audio to several studios and can only be created using the Programs panel in the Java Toolbox Web-GUI. Once multi-unicast connections have been created you can press CONNECT on the codec keypad to connect without using the Java or HTML5 Toolbox Web-GUIs. The codec can also simultaneously send up to 3 different mono or stereo multi-unicast audio streams simultaneously to a maximum of 50 endpoints in total.

 

Multicast Programs

A multicast audio stream can be used to broadcast to unlimited numbers of 'subscriber' (client codecs) wanting to receive a particular audio transmission. Multicast transmissions are broadcast by a multicast server codec using a dedicated IP multicast address, which looks similar to a regular IP address, and multicast subscribers request transmissions from this address. It is possible to simultaneously broadcast 3 separate stereo streams in multicast server mode and distribute each of these streams to unlimited endpoints over compatible IP networks.
