administrative uses.  ImmediaTV recommends the use of UDP ports 1024 and higher.  
The MVN-XC440, however, will accept any legal value. 

 

Reception: 

selects the address to receive from.  The options are: 

o

 

Unicast:

 the packets are being sent to the IP address of this Ethernet port.  The 

address of the Ethernet port can be set or reviewed in the Network Tab. 

o

 

Multicast:

 the packets are being sent to a Class-D multicast address (between 

224.0.0.0 and 239.255.255.255).  If this option is selected, a new field is 
displayed to accept the multicast address: 

 

 

 

The MVN-XC440 will warn the user if the address entered in this field is not a 
multicast address.  The device includes a full implementation of IGMP V1/V2/V3 
to convey group membership information to upstream routers; IGMP is 
configured in the Network Tab. 

o

 

Broadcast:

 the packets are being sent to a broadcast address (either the all-hosts 

broadcast address of 255.255.255.255 or a subnet broadcast address).  Note that 
this is extremely rare in practice. 

 

Source: 

If desired, the MVN-XC440 can filter packets by source IP address.  This is 

useful when the network includes a primary and a backup stream, sent to the same 
address, but from different sources.  The options are: 

o

 

Any Address: 

this input will accept packets from any address. 

o

 

Specific Address:

 this input will only accept packets from a given specific 

address.  When this option is selected, a new field appears where the desired 
source IP address can be entered: 

 

Unicast/Broadcast

Multicast

Unicast/Broadcast

Multicast

 

 

The 

Source Address

 must be a valid unicast address.  In case of Multicast 

reception, the MVN-XC440 will go into SSM (Source-Specific Multicast) mode.  
If IGMP V3 is in use, the card will use it to inform the network of the choice 
selection.  Note that the MVN-XC440 does 

not

 require an IGMP V3 network to 

operate in SSM mode, as it can filter packets in real-time at line rate. 

 
The IP Input Ports will automatically detect the use of RTP, in a packet-by-packet basis.  The 
MVN-XC440 will only accept RTP version 2 packets satisfying the following conditions:
