Device	Monitoring device name.
PID	PID of the channel source.
Codec	Codec Type. *Audio Codec Types: MPEG, AC3, E-AC3, DTS, ADTS/AAC, ADTS/HE-AAC, LATM/AAC, LATM/HE-AAC, ATMOS. Video Codec Types*: H.264, MPEG2, MPEG1, JPEG2000, H.265, SMPTE-2022-6, SMPTE-2110-20.
Language	Language of the PID type (Relevant for Audio, Subtitles, Teletext, AES3, ID3 Metadata).
Bitrate	PID bitrate. (either single CBR value or dual VBR value).
Short Term Loudness	Short Term Loudness measures the loudness of the past 3 Seconds (in LUFS) based on the EBU R128 standard.
Momentary Loudness	Momentary Loudness measures the loudness of the past 400 Milliseconds (in LUFS) based on the EBU R128 standard.
Current True Peak	Specifies the Current True Peak based on the EBU R128 standard.
Current Dialnorm	Specifies the current Dialnorm based on the EBU R128 standard.
Hourly LRA	Specifies the Hourly LRA based on the EBU R128 standard.
Hourly True Peak	Specifies the Hourly True Peak based on the EBU R128 standard.
Hourly Integrated	Specifies the Hourly Integrated based on the EBU R128 standard.
Daily LRA	Specifies the Daily LRA based on the EBU R128 standard.
Daily Integrated	Specifies the Daily Integrated based on the EBU R128 standard.
