Enter the name of the stream for better reference.
Unicast/Multicast.
IP for the destination Multicast group, if selected in the field Type.
Sender UDP port (the same as configured in the encoder settings for output
streaming).
Elementary stream encapsulation, either UDP only or UDP/RTP.
Choose the Ethernet connector for the input signal: Data 1 or Data 2.
Select a configured VLAN ID.
The dejitter buffer for IP transforms the variable delay into a fixed delay. It holds the
first packet received for a period of time before it sends it out to the decoder. This
time period is necessary for reordering the packets as well as to compensate the jitter
and optionally to apply FEC correction and/or the combine with the second, dual
streaming input.
Enter the value for this holding period in ms (for more information see section 19
"Buffer Delay Management" on page 102).
NOTE: The delay time of the input source must not exceed 200 ms if the sample rate is
192 kHz (see "Demux Configuration" in section 13.2 "Assign Input Source/Codec
Profile" on page 44).
Enable by selecting "ON" in the virtual switch (see section 14.2)
Enable by selecting "ON" in the virtual switch (see section 14.3).
Activate Dualstreaming by selecting "ON" in the virtual switch "Dualstreaming" in the
last field. The menu will be expanded to the additional configuration field.
Configure the IP parameters for Dualstreaming. For the Ethernet input you can set up
the same or different sources Data 1/2.
