Standard CSA CST-RT-019 HDTV

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

- Scaling loudness measurement: LKFS curve weighting Leq (R2LB)

weighting ITU-R BS.1770-1

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

- Measurement methodology of e dynamiqu

it permits the following loudness of excursions:

s for dialogue: + - 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
