11.6.6.4 IP Address Type
Define whether unicast or multicast is used for TS over IP reception.
M6100>TS over IP >> Monitor
When unicast is used the device listens to the IP address of the input selection, being one of the
following:
• Data 1;
• Data 2;
• Data Bond.
When multicast is used a specific multicast address must be defined.
This is the IP address where the different devices in the multicast group have to listen to.
IP Multicast uses a reserved range of IP addresses (from 224.0.0.0 to 239.255.255.255). The IGMP
(Internet Group Management Protocol) is used as communication and coordination protocol between
source and recipients.
With IGMPv3 a source address can be detected so that traffic from this source only is selected.
To configure an IP Address, refer to DataIPConnectivity.onpage110
IGMPv2 and IGMPv3 (standards) are supported by the M6100 Satellite Broadcast
Modulator.
11.6.7 Traffic Profile
In the M6100 Broadcast Satellite Modulator the traffic profile must comply with the profile used in the
encoder/video multiplexer. This is needed to ensure that the M6100 Broadcast Satellite Modulator
recognizes the traffic.
11.6.7.1 VBR (Variable Bit Rate)
This is the property of a transport stream, where the packet rate is varying over time. It means that
when the compressed data contains less information, less packets are sent. In other words, the
number of packets in two time intervals of the same duration is variable.
