7.6.2. TRANSPORT
•
Transport Bitrate:
This field enables the user to set the transport bitrate in Kbps.
•
Transport Mode:
This selector enables the user to set the transport mode. The mode options
are MPEG, DVB or ATSC.
7.6.3. IP TRANSPORT
•
IP Output:
Placing a checkmark in the IP Output checkbox enables the IP output.
•
Output Protocol:
This selector enables the user to pick the output protocol for the carriage of
transport stream over IP. The options are UDP and RTP.
When the first option is selected, a number of TS packets are carried as the payload of a UDP
datagram. UDP, alias User Datagram Protocol, is classified as part of the Transport Layer in
the TCP / IP stack.
The second option uses RTP, alias Real-time Transport Protocol, to carry transport packets. As
with UDP, the RTP payload carries an integral number of transport packets. RTP fits within the
Application layer in the TCP / IP stack and the majority of RTP implementations are built on
UDP.
•
Network Interface:
This selector enables the user to select the network interface. The options
are Data – Main, Data – Backup and Control.
•
Destination IP:
This field enables the user to enter the destination IP address, which can be
either unicast or multicast.
•
Port:
This field enables the user to enter the port for the destination IP.
•
MTU Size:
Placing a checkmark beside the MTU Size box enables the user to adjust the size of
the largest packet that a network protocol can transmit, alias MTU, or maximum transmission
unit. The user can enter the MTU size in the adjacent field. The value range is 300 to 8192
bytes.
•
TTL Size:
Placing a checkmark beside the TTL Size box enables the user to adjust the
mechanism that limits the lifespan of data in a network, alias TTL, or time to live. The purpose
of this mechanism is to stop an undeliverable stream packet from circulating endlessly on the
network. Each hop reduces this number until it becomes zero at which time the stream packet
is deleted. The user can enter the TTL size in the adjacent field. The value range is 0 to 256.
