Table: Loudness monitoring


With optional loudness module enabled, Volicon Media Intelligence service performs loudness meter measurements to meet following standards: EBU R 128, BS-1770-1, BS-1770-3, ATSC A/85 and EBU Tech 3341/2/3; Volicon Media Intelligence service loudness module, accurate per each video frame, takes measurements every 100 milliseconds; measurements able to be done with/without gating windows (-10 dB but adjustable)

Gating mode

Dropdown used to select ATSC1, ATSC3 or EBU

Input adjustment

Adjustment to input level for fine tuning; a floating-point value will be added to the input measurement


Loudness Range Measurement (LRA) quantifies variation in time-varying loudness measurement; supplementary to main audio measure, program loudness, of EBU R 128; measures variation of loudness on macroscopic time-scale loudness units (LU); LRA computation based on measurement of loudness level specified in ITU-R BS.1770 - with different gating threshold; LRA not to be confused with other measures of dynamic range

Long IM

Long-form Integrated Measurements: Greater than two minutes; total of seven user-defined, configurable measurements (e.g., 1 hour, 6 hour, 1 day, 5 day intervals); long-term values Volicon Media Intelligence service default setting: 60, 360, 1440, 0, 0, 0, 0

Short IM

Short-form Integrated Measurements: Two minutes or shorter; total of seven user-defined, configurable measurements (e.g., 10s, 30s, 60s); short-term values Volicon Media Intelligence service default setting: 10, 15, 20, 30, 60, 120, 0


Dialnorm indicates level of average spoken dialogue within encoded audio program; short-, long-term values often factory preset; Dialnorm not to be enabled when encoder ingesting digital audio stream (e.g., optical, S/PDIF or Dolby AC-3)

True peak

Enables monitoring the value of the audio signal waveform of a program in the continuous time domain; detects peak loudness that otherwise would escape the sampling process

Number of free text lines


Number of characters in a free text line

Score line

The line on which the scores will be burnt in a 1-based index system

Status line

Line on which scores to be burnt in 1-based index system; if using default height, this is line before last

Video input line

Table: Timestamp

Timestamp enable

Dropdown used to position the info on player screen

Auto calculate offset from UTC

Based on probe’s time setting


Specifies how time is displayed: %month%-%day%-%year%%hour%:%minutes%:%second%/%frame%

Offset from UTC

Manually sets a time zone offset; setting overrides probe O/S time zone setting; Volicon Media Intelligence service uses value instead of offset in probe
