Streaming 

Streaming parameters objectives: 
 
-Provide  a  ‘test’  tool  to  check  in  real  time  the  bandwidth,  delay  and  jitter  of 
the IP connection between two Prodys IP codecs. 
 
-To allow adjustment of the various reception parameters to optimize the unit 
to provide the best quality real-time audio streaming for a particular network 
connection. 

 
These tools are grouped in the following manner:  
 
1 – Protocol. 
2.- Reception parameters. 
3.- Test tool. 
 

Streaming  Protocol

:  This  option  allows  the  user  to  configure  the  streaming 

protocol to use for transmission over IP. There are five choices;  

•

 

Proprietary: Prodys proprietary IP streaming protocol. 

•

 

Proprietary v2: Prodys proprietary IP streaming protocol version 2. 

•

 

SIP

17

: SIP is a signaling protocol for creating, modifying, and terminating 

sessions with one or more participants. For more information about this 
protocol and compatibility with other units please contact 
[email protected]. 

                                        

17

 SIP protocol is available from version 4.7.1.
