M6100> TS over IP >> TS Encap Protocol
To transport these time critical media files over IP networks it is possible one of the following
protocols can be used.
• UDP (User Datagram Protocol);
• RTP (Real Time Protocol);
• RTP FEC (Real Time Protocol with Forward Error Correction).
The used protocol depends on the situation.
The following sections explain:
• The different protocols;
• When to use a certain protocol.
11.6.6.1 UDP
The User Datagram Protocol is used to send data (MPEG Transport Streams) from a source
(encoder) to the modulator over an IP network. The protocol does not require to setup special
transmission channels or data paths. UDP provides an unreliable service and it is possible that
packets arrive out of order, are duplicated or are lost without notice. This means that UDP can only
be used in simple IP networks where no jitter, packet loss or packet reordering is expected.
For example in a DSNG truck where two encoders are connected to two Modulators via a simple
Ethernet switch. See the following figure:
The TS packets are packed into IP packets with only a UDP header. This is displayed in the
following figure:
