12.8 Destination IP Settings
This section sets the IP address that is assigned to the outgoing IP stream when
working in MPTS mode. There will be only one multiplex created and only one address
may be assigned. This address will be used across all of the output Ethernet ports as
the four ports are on an integrated switch.
12.8.1 IP Address:
This is the IP address that is assigned to the output unicast or multicast MPTS stream and will be reported in the resulting
MPTS stream as the Destination IP Address.
12.8.2 Destination Port: [1-65535]
This is the port number that is assigned to the output unicast or multicast MPTS stream and will be reported in the resulting
MPTS stream as the Destination Port Number.
12.8.3 Enable Multicast:
This check box enables the use of multicast as an output. The Ethernet card
does not use the actual assigned destination
IP address range to determine if unicast or multicast transmission is desired. In other words, merely assigning a multicast
address in the range 224.0.0.0 through 239.255.255.255 will not cause the output to be multicast.
•
If this check box is unticked
ARP protocol will be used to find and establish a unicast connection to the computer or receiving device with
the destination IP address. The stream will be unicast to the destination address specified. If the address of the
destination specified is not found, the transmission will default to multicast.
•
If this box is ticked
The Ethernet interface will not need to find the destination IP address before beginning transmission. It will assume
that there are multiple receivers of the stream. The stream will be multicast to the address specified.
12.9 Protocol Settings
In this section, some configuration settings for the IP protocol may be changed.
12.9.1 Encapsulation:
Defines the type of IP encapsulation to be used for IP transmission.
•
UDP
User Datagram Protocol is a connectionless protocol (as opposed to TCP)
and is commonly used to send audio and video over Ethernet. There is no
ordering of the data enforced and data arriving late is ignored.
•
RTP
Some routers support RTP (Real-time Data Protocol) and will pass data sent under this protocol with priority.
12.9.2 Number of TS Packets per Frame:
Here the number of MPEG packets that are encapsulated into each IP packet may be defined. The default value is seven,
which is also the maximum number. Encapsulating more MPEG packets in each IP packet reduces overhead but there is more
MPEG data loss with each lost IP packet. Assigning less MPEG packets per IP packet increases overhead but results in a
possibly more robust stream. Seven is most commonly used.
12.9.3 Enable Pro-MPEG FEC:
The DVIS supports transmission with Pro-MPEG FEC protocol defined by Pro-MPEG COP#3. For more information on
configuring Pro-MPEG FEC see the
12.9.4 L value: [1-20]
Pro-MPEG FEC Values
12.9.5 D value: [1-20]
Pro-MPEG FEC Values
12.9.6 Col port: [1-65535]
Port number to use for transmission of FEC column data.
