Fields Explanation
PCR Restamping Choices are Off or On. This is PCR (Program Clock Reference) Restamping of
transport packets. For a SFN, this function must be disabled. Either setting is
valid in MFN mode, but it is usually On
Flow Adaptation Choices are Off or On. Enables or disables the transport stream flow (bit rate)
adaptation by the addition or deletion of null packets. For a SFN, this function
must be disabled. Either setting is valid in MFN mode, but it is usually ON.
Null Packet Removal Choices are Keep All, Discard Min(imum), or Discard All.
Keep All = All incoming null packets are kept.
Discard Min = Discard the minimum number of Null packets to meet required
data rate.
Discard All = Discard all incoming null packets.
For a SFN, this function must be set to Keep All. Any setting is valid in MFN
mode, but Discard All is usually selected
TEI Flag Choices are Unchanged or Set. If Set is chosen, the TEI (Transport Error
Indicator) flag is enabled in each transport stream packet. This is used to
indicate uncorrected errors in the input transport stream. In the SFN operating
mode, this function must be set to Unchanged, where the TEI flag will remain
disabled. In the MFN mode, either setting can be used
MFN MIP Control MIP is Mega-frame Initialization Packet. On Enables the use of MIP packets
in MFN mode. Select On if MIP packets are to be used to control modulation
parameters.
MIP Frequency
Offset
No value can be entered. This is for Status only. MIP Frequency Offset is an
optional frequency offset included in the MIP packet and added to RF
frequency.
Use frequency Offset Choices are Local or MIP Control
