Total bitrate: Total transport stream bitrate including null packets (PID
8191)
Min total bitrate: The minimum total bitrate including null packets
Max total bitrate: The maximum total bitrate including null packets
Effective Bitrate: Transport stream bitrate excluding null packets (PID 8191)
Min effective
bitrate:
The minimum effective bitrate excluding null packets
Max effective
bitrate:
The maximum effective bitrate excluding null packets
DVB-T/T2 status - DVB-T/T2 demod info:
Sync: A “bulb” indicating frequency lock when green, red
indicates no lock
Level: This is a measure of the stream signal power. It is
expressed according to the level mode selection made in
the Setup - ETR view:
dBm: in decibels relative to a reference value of 1mW.
dBuV: in decibels relative to a reference value of 1µ V
dBmV: in decibels relative to a reference value of 1mV
Signal to noise
ratio:
The signal to noise ratio in dB
Modulation error
ratio:
The modulation error ratio in dB
Frequency offset: The measured centre frequency offset in kHz
Spectrum inversion: The spectrum inversion parameter may have the value
'Normal' or 'Inverted'.
Pre Viterbi BER:
Pre LDPC BER:
The bit error rate before Viterbi or LDPC error correction
Pre RS BER:
Pre BCH BER:
The bit error rate before RS or BCH error correction
Post BCH FER: The frame error rate after BCH error correction
1 PPS input lock: A “bulb” indicating reference signal lock when green, red
indicates no lock
SFN drift: The SFN drift measured for the demodulated signal, with
the configured SFN drift zero offset subtracted
