Unicast TCP
This method transports data using standard TCP (Transport Control Protocol) and should only
ever be used for single point-to-point transfer of data.

Each encoder is ‘paired’ to a decoder
with a point to point data link.
Figure 4. Using Unicast TCP as a Single Point-to-Point Transfer of Data
TCP is a connection-based protocol and, therefore, data is guaranteed to be delivered.
However, in the event of excessive network trafc, delivery may be delayed impacting
real-time performance.
NOTE: Multiple decoder connections are theoretically possible using this method but
NOT recommended. Each additional connection creates extra loading on the
encoder CPU which ultimately results in poor display performance. In addition,
multiple TCP streams carrying the same source data is an inefficient use of
network bandwidth.
