Standard CSA CST-RT-019 HDTV

This new standard, being signed, complements the recommendation CST - RT 017 to define methodologies for assessing the sound dynamics.

- Change of scale for measuring loudness: LKFS curve weighted Leq (R2LB)

weighting ITU-R BS.1770-1

- Average level dialogue s LKFS -25 + - 2 dB

- Measurement methodology dynamiqu e

we allow the following loudness of excursions:

for dialogue s + - 7 dB measured in short term around the Dialog level

for all the sound elements of the program: + - 12 dB measured in short term around the Dialog level

management of peaks mixing 5.1 -3 dB FS (term generalized to all mixing versions, 5.1, LtRt, LoRo, Dual Mono)
