Any of the following settings will ensure CALM ACT compliance. TheTV_5B_GEN setting
is the default setting that is recommended.
TV_5B_GEN : This is the recommended setting that provides moderate degree of
dynamic range processing and works with a wide variety of content.
TV_5B_LIGHT: similar to the GEN setting, but has a slower transition on sharp loudness
changes.
TV_5B_HEAVY: Stronger reduction to loudness changes but results in less dynamic
sound.
TV_5B_Loud : Strongest loudness suppression.
IT_LOUD_LIMIT : this provides a slow adjustment to the program loudness. This is
useful for live applications where the program loudness may be changing slowly.
Protect Limit : This provides a simple limiter function to protect against overload.

SDI source option
Audio Group: Audio group for input audio.
Audio Pair: Audio pair (stereo pair) for input audio signal
.

Advanced Transport Options
PAT: The Program Association Table of a MPEG-TS. Default value is 80 milliseconds.
This defines the repetition rate of a PAT table in the MPEG-TS. Higher value reduces
the overhead of the PAT component on the overall MPEG-TS bandwidth, hence
providing slightly more room for audio and video signaling.
PMT: The Program Map Table of a MPEG-TS. Default value is 350 milliseconds. This
defines the repetition rate of a PMT table in the MPEG-TS. Higher value reduces the
overhead of the PMT component on the overall MPEG-TS bandwidth, hence providing
slightly more room for audio and video signaling.
PCR: The Program Clock Reference of a MPEG-TS. Default value is 40 milliseconds.
This defines the repetition rate of the PCR in the MPEG-TS. Higher value reduces the
overhead of the PCR component on the overall MPEG-TS bandwidth, hence providing
slightly more room for audio and video signaling. However, lower values may be needed
for some networks with high jitter downstream of the encoder (for example IP network
connections add jitter, so a lower value may be needed).
