5.5.4.4 ProMPEG FEC (SMPTE 2012-1, 2)
5.5.4.4.1 FEC Parameters
FEC is set up on a per-Transport Stream basis. The following description applies to
the graphical user interface.
If the user has the appropriate license installed to use FEC then below are the
parameters which can be set (with itemised lists of available values where
appropriate).
Table 5.118 FEC Parameters
Parameter Values Description
IP Encapsulation UDP UDP encapsulation of TS packets
RTP RTP encapsulation of TS packets
RTP/FEC Column
UDP/RTP encapsulation of RTP Packets with added one-
dimensional FEC
RTP/FEC Column and Row
UDP/RTP encapsulation of RTP Packets with added two-
dimensional FEC
Number of Rows 4 - 20
An integer between 4 and 20. See FEC constraints section for
allowable ranges.
Number of Columns 1 - 20
An integer between 1 and 20. See FEC constraints section for
allowable ranges.
Alignment Block Aligned
Non Block Aligned
If the user does not have a license to use FEC then the available IP Encapsulation
options become UDP, RTP, RTP/FEC Column (No License) and RTP/FEC Column
and Row (No License). If either of the ‘(No License)’ options is selected then IP
Encapsulation will be set to RTP and FEC will not be enabled. If subsequently the
license is enabled for FEC then the ‘(No License)’ suffix will be removed from the
displayed valued of IP Encapsulation
Constraints on FEC Parameters
To promote interoperability and simplify implementation, limits are specified for
values of the L (number of columns) and D (number of rows) parameters. ProMPEG
FEC requires equipment manufacturers to support all combinations of values of L
and D within these limits. The specified limits are:
Columns Only: (L x D <= 100) and (1 <= L <= 20) and (4 <= D <= 20)
Rows and Columns: (L x D <= 100) and (4 <= L <= 20) and (4 <= D <= 20)
