54. EMS Multicast mode transmission On a network that can support it the multicast mode can optimise the resource usage when an audio stream has to be distributed simultaneously to several destinations Contrary to the normal bidirectional unicast mode this mode is unidirectional one sender encoder sends a stream towards a multicast group address and one or several decoders receiving the stream pick up the packets sent to this group address and decode the audio stream On the SCOOP 5 the operating mode stays quite similar to the normal mode with mainly two differences in the multicast mode e A codec must be set as sender or receiver device e SIP is not used and hence the SIP configuration is not relevant For the operation it is assumed the network statically supports UDP multicast i e routers of the network recognise and deal with routing the packets with multicast group addresses For obvious reasons the coding setup is entirely decided at the source On the codec on the audio source side hence sender of the encoded stream the procedure for setting up a multicast stream is the following e Set the codec in multicast send mode To do this refer to the AoIP Parameters sub menu page 51 e Select on this codec the desired audio coding parameters e Start the streaming as for setting up a call in normal mode enter the IP group address then press the key Note that the codec decodes its own stream on its audio o
