As can be seen, there is an independent control bar for each connection. Each of
the connection bars will show the line status in real time. The procedure to
establish a call is the same as that for Unicast connections.
As for Unicast connections, the Tx and Rx parts of the connection are divided so
that it is possible to receive from one end at the same time the unit is sending
audio on one or more Tx connections.
In addition, it is possible to make or hang up several connections at the same
time by using the ‘Group Call’ and ‘Disconnect All’ buttons respectively.
This operation mode is compatible neither with the IP ‘DOUBLE MODE’
,
nor with BackUp operation mode.

Prodys Proprietary set of protocols
Prodys developed this proprietary set of protocols to carry out IP streaming
connections, due to the lack of a standard in this regard:
•
Prodys Real Time Control Protocol (P-RTCP): This is a protocol based
on TCP that allows for the establishment and termination of a
connection as well as for the negotiation of the codec mode (automatic
audio synchronisation in all modes).
•
Prodys Real Time Protocol (P-RTP): This is a protocol based on UDP
used for the transmission of audio.
•
Prodys eXtended Real Time Protocol (PX-RTP). This is a protocol based
on UDP used for the transmission of multicast audio.
•
Prodys Upgrading/Identifying Protocol. This protocol is based on UDP
and used to identify/upgrade the units.
•
Prodys External Protocol (P-XP). This protocol is based on TCP and can
be used for controlling the units from an application other than the
web page or ProdysControl.
•
Prodys Auxiliary Data Protocol (P-AUXP). This protocol is based on UDP
and used for transmitting/receiving auxiliary data
17
.
•
Prodys U-bit Protocol (P-UbP). This protocol is based on UDP and used
for transmitting/receiving the User Bit from the AES/EBU frame.
Available from version 4.8.0 on.
It is worth mentioning here, that at the time of writing, Prodys
has a close relationship with the EBU group N\ACIP which have
started the first committee in order to define an standard in
audio contribution over IP. Prodys work in the definition of the
standard along with the members of the EBU group, in

Available from version 4.8.0 onwards.
