The ISDB-T threshold parameters are:
ISDB-T threshold — Edit:
Name: A text field describing the threshold template
Maximum pre Viterbi/LDPC BER:
Threshold level for bit error ratio before Viterbi or LDPC error
correction
Maximum pre RS/BCH BER:
Threshold level for bit error ratio before Reed-Solomon or BCH
error correction
Maximum post BCH FER: Threshold level for bit error ratio after BCH error correction
Minimum MER: Threshold level for calculated modulation error ratio
Minimum signal to noise ratio: Threshold level for signal to noise ratio (dB)
Minimum signal strength:
Threshold level for minimum signal strength. 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
dBμV: in decibels relative to a reference value of 1μV
dBmV: in decibels relative to a reference value of 1mV
Maximum signal strength:
Threshold level for maximum signal strength. 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
dBμV: in decibels relative to a reference value of 1μV
dBmV: in decibels relative to a reference value of 1mV
