ATSC Approves Successorto Its "A/85 Recommended Practice"
MB Docket No. 11-93By this Public Notice, the Media Bureau announces that the Advanced Television Systems
Committee, Inc. ("ATSC") yesterday approved a successor document to its A/85 Recommended Practice
("ATSC A/85 RP"). In the Notice of Proposed Rulemaking ("NPRM") to implement the Commercial
Advertisement Loudness Mitigation ("CALM") Act, the Commission directed the Bureau to issue a
Public Notice announcing the ATSC's approval of any successor to the ATSC A/85 RP.1 The ATSC has
published this document on its website at http://www.atsc.org/cms/standards/a_85-2011a.pdf.2 This
document adds an Annex K titled "Requirements for Establishing and Maintaining Audio Loudness of
Commercial Advertising in Digital Television When Using Non-AC-3 Audio Codecs."3
On May 27, 2011, the Commission released the NPRM, which sought public comment on its
proposed rules to implement the CALM Act. The CALM Act directs the Commission to incorporate by
reference and make mandatory the ATSC A/85 RP, "and any successor thereto, approved by the
Advanced Television Systems Committee, only insofar as such recommended practice concerns the
transmission of commercial advertisements by a television broadcast station, cable operator, or other
multichannel video programming distributor."4 By statute, the Commission must adopt final rules no
later than December 15, 2011.
On July 18, 2011, in anticipation of this successor document to the ATSC A/85 RP and in
response to a request by the ATSC, the Media Bureau extended the reply comment filing deadline in this
proceeding until August 1, 2011 "to allow interested parties an opportunity to review and provide
comments on the successor document to the ATSC A/85 RP."5 This document, for which we extended
the reply period, is now available.
