ABSTRACT
This chapter focuses on digital television loudness management and explains proven, effective and required practices for mastering loudness across the television audio ecosystem, with particular focus on television engineering and operations. It explains the mastering of A/85's vital technical practices for digital television audio loudness management when using the Advanced Television Systems Committee (ATSC) AC-3 audio system, including references to the government digital television loudness regulations and enforcement at the writing. The chapter shows loudness practices for content transitioning, the recommendations can apply to every situation for normalizing loudness at any step throughout the entire audio ecosystem. It identifies important considerations for establishing a loudness normalization plan as specified in the 2011 Federal Communications Commission Report and Order based on the 2009 and 2011 releases of ATSC A/85. The output stream of the device was connected to the ATSC encoder in audio pass-through mode, enabling the 567's AC-3 audio stream to remain intact during emission encoding.
