Setting Transport Mode
Connections can be established between the encoder and their receivers,
including UDP (Unicast), UDP (Multicast), RUDP (Unicast), TCP (Uni-Connection)
and TCP (Multi-Connection). Choose a proper one based on your networking
conditions. By default, TCP (Multi-Connection) is used.
UDP (Unicast) indicates that the encoder sends a UDP stream directly to the
receiver. It is used where lower latency matters. And multiple simultaneous
streams will work independently for multiple receivers.
■
UDP (Multicast) indicates that the encoder sends the UDP stream to a
multicast group. It is used for one-to-many broadcast for lower CPU
utilization. Parameters in a multicast configuration include:
■
Multicast IP ranges from 224.0.0.0 to 239.255.255.255.
■
Subnet Mask can be legitimate value ranging from 255.0.0.0 ~
255.255.255.252.
■
Time To Live ranges from 1 to 255. The default value is 4.
■
RUDP (Unicast), Reliable User Datagram Protocol, is a connection-oriented
and unicast protocol. RUDP helps to maintain the flow control and reliability
of data transfer. The transmission control algorithms on both sending and
receiving sides guarantee the RUDP capable of recovering from data loss,
duplication, delay, and as well as reordering.
■
TCP (Uni-Connection) indicates to establish single TCP connection between
the encoder and receiver, and transfer all A/V packets are transferred via
one port. Compared with UDP (Unicast) or TCP (Multi-Connection), it has
lower CPU utilization. It is used where reliable transmission of data
matters,which makes it suitable for 4K NDI streams.
■
TCP (Multi-Connection) indicates to establish multiple TCP connections
