5-9
MODE SELECTIONS:
UDP PACKETS
-
the demodulator outputs seven MPEG
packets encapsulated in a UDP datagram.
COP 3 RTP - the demodulator outputs seven MPEG
packets encapsulated in a COP 3 compliant RTP
datagram.
COP 3 RTP FEC - the demodulator outputs COP 3
compliant Column FEC packets in addition to the RTP
datagram.
IP ADDR:
{XXX.XXX.XXX.XXX}
This is the IP address to be used by the Ethernet Data
Interface. This will be the source IP address for all
Ethernet traffic generated by this interface.
UDP PORT:
{XXXXX}
This is the source UDP port to be used by the Ethernet
Data Interface.
DEST IP ADDR:
{XXX.XXX.XXX.XXX}
This is the destination IP address that the Ethernet Data
Interface will sent all Ethernet traffic to.
Unicast Destination IP Addresses
When the destination address is a Unicast address
(000.000.000.000 thru 223.255.255.255) the Ethernet Data Interface will use an ARP
Request to determine the Destination MAC address to which the data will be sent. This
could be the MAC address of the final destination or the MAC address of the first router
through which this data will pass. The Ethernet Data Interface will not output any data
until it receives an ARP Reply to its ARP Request.
