How do I choose the right algorithm?
The algorithm you select will not only affect the quality of the broadcast but it will also contribute to
the amount of latency or delay introduced. For example, if MP2 algorithms are used, program
delays will be much longer than when using Tieline Music or MusicPLUS algorithms. This is due to
the additional inherent encoding delays involved when using MP2 algorithms. This can be a major
consideration for live applications that integrate remotes into a broadcast. The algorithm you select
to connect with will also depend upon:
·
The codecs to which you are connecting (Tieline versus non-Tieline)
·
Whether you are creating multi-unicast connections.
·
Whether you are connecting using SIP or not.
·
The uplink bandwidth capability of your broadband connection.
Important Notes:
Music and MusicPLUS algorithms cannot be used over SIP
connections. Use MP2 algorithms at 64kbps mono or 128kbps stereo for high quality
connections when using SIP, or use G.711 and G.722 if required. Tieline G3 codecs do
not support connections using AAC, aptX Enhanced and Opus algorithms and will default
to MPEG Layer 2 if an incoming connection is configured to use these algorithms.
It can be a good idea to listen to the quality of your program signal using each algorithm and to see
how it sounds when it is sent at different connection bit rates (as well as different FEC and jitter-
buffer millisecond settings). This will assist you to determine which is the best algorithm setting for
the connection you are setting up. Please see the following table for details on the connection
requirements of the different algorithms available.
