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. |
