6.9.8 ETR 290 — T2MI (requires T2MI-OPT)
T2MI monitoring is a licensing option available for transport streams over ASI and Ethernet. T2MI is
enabled on a per stream basis, most of the information is found in this GUI extracted from the L1 current
packets in the T2MI streams. The full parsing of this information table is found in the ‘Tables’ section.
Please note that the T2MI stream needs to have either a relative or an absolute T2 Timestamp to be
received properly. Signals without timing information can not be received.
Overview:
T2 timestamp:
The last received T2 timestamp. The probe supports both relative
and absolute timestamps.
Super frame index: The last received superframe index.
Frame index: The index of the last received frame.
Input streams: Indicates whether Single or Multiple Input Streams are used.
Coding and modulation:
Whether the stream uses Constant Coding and Modulation or Adap-
tive Coding and Modulation.
Input stream sync: The Input Stream Synchronizer (ISSY) value.
Input stream format: The format of the input stream. Will normally be ‘TS’.
Input stream identifier: The input stream identifier for the current stream.
Num TS pkt. last T2MI frame:
The number of transport stream packets that was in the last T2MI
frame.
Null packet deletion: Whether null packet deletion is in use or not.
High efficiency mode: Whether high efficiency mode is active or not.
Crc Errors BB header:
The number of CRC errors on the BB header detected since the
monitoring of the stream started.
