LAN Parameter
• Decoder Buffer Mode: The Audio transmission via IP networks with
UDP
1
requires a buffer in the decoder because of different delays (jitter) of
the individual IP packages in the network. The buffer administration
should be set by default to Automatic mode. For safety reasons, the buffer
at the automatic buffer administration is bigger than possibly necessary.
If you know the parameters from your network provider and a delaying
time is guarateed to you, you can set the buffer administration to Fixed.
Thereby the total delay of the Audio transmission can be optimized.
• Decoder Buffer Size: If the Decoder Buffer Mode is set to Fixed, you can
set the buffer size in a range of 20 ... 2000 ms.
• Encoder Packet Size: For an optimization of the total delay the size of the
packages can be adapted in the encoder. Whereby with bigger packages
the IP overhead will be minimized. However, therefore the total delay
increases and with a loss of a big package the interference can be heard
much more clearly. You can set the package sizes in a range of 5 ... 50 ms.
The standard value is 20 ms.
• Remote IP Address: In the LAN operation mode you can enter the IP
address of the remote station here (z.B. 192.168.12.15).

UDP = User Data Protocol: minimum, connectionless network protocol
ATTENTION If a loss of packages should occur (see CHAPTER4.9.1, Page 98), please try at
first whether it can be avoided with a bigger buffer.
NOTE
If you are using the ISO/MPEG Layer 2/3 algorithm the package size is set
by default internally always fix to 24 ms.
