IV.6.6
RTP protocol
This protocol performs plain streaming of audio embedded into RTP/UDP
packets. The main application is also compatibility with a very wide choice of
audio streaming devices.
It is remarked that this protocol does not include automatic procedures for taking
an incoming call or streaming supervision. Therefore the user is required to
enable or disabling manually any incoming or outgoing stream.
IV.6.7
SIP
The European Broadcast Union (EBU) is promoting the interoperability of audio
codecs for any manufacturer. For this purpose the use and the application of a
subset of the Internet Protocols has been proposed. This effort will allow to
setup in a friendly way audio streaming communications between several vendor
equipments.
The deployment of SIP Protocol Servers among the network will support calling
remote parties just by invoking their network name regardless of the actual
public o private IP addresses. Neither is required to manage the office routers
and the firewall’s TCP/IP ports for any new communication path.
The physical location, often related to fixed IP addresses or subnets, is not
further meaningful. In this sense, portable audio codecs will profit with an easy
call procedure. Neither is required to agree ahead on the audio compression type
and data stream rate, because the SIP Protocol manages by itself to negotiate
the convenient communication details with the remote party.
For Prodys’ former customers performing a call using SIP is much the same as
using Prodys’ proprietary protocols given that the SIP configuration is set.
SIP supports up to date only unicast streaming. Any Prodys IP Family codec’s
audio compression mode is supported also if SIP protocol is in use.

The apt-X compression is still undefined by the EBU Tech 3326 standard. For compatibility
reason this mode is not supported if SIP protocol is selected.
