ATSC has delivered an updated version of ATSC A/85, the core technology mandated by the Commercial Advertisement Loudness Mitigation (CALM) Act, to the Federal Communications Commission (FCC).
The A/85 Recommended Practice (Techniques for Establishing and Maintaining Audio Loudness for Digital Television) provides the industry with uniform operating strategies that optimize the audience listening experience by eliminating wide variation of television loudness. The ATSC, which optimized A/85 based upon industry experience and feedback is fortunate to have industry experts from our member organizations participate in this important work.
As approved by ATSC members, the revised version of A/85 includes an update of the reference to the International Telecommunications Union (ITU) recommendation for “algorithms to measure audio programme loudness and true-peak audio level.”
The updated ATSC Recommended Practice A/85:2013, dated March 12, 2013, is the successor document to Recommended Practice A/85:2011, dated May 25, 2011.
The ATSC looks forward to continuing to collaborate with the FCC on the implementation of the CALM Act.
