FCC Ponders Secondary Audio for Emergency Alerts
NRPM addresses Communications and Video Accessibility Act of 2010
WASHINGTON: Federal regulators are proposing that emergency broadcast
information be provided on secondary audio streams. The details are included in the Federal Communication
Commission’s Nov. 19 Notice of Proposed Rulemaking on making emergency messages
accessible to blind people, a requirement of the Communications and Video Accessibility Act of 2010.
“This NPRM proposes to make
televised emergency information more accessible to individuals who are blind or
visually impaired by requiring the use of a secondary audio stream to provide
emergency information aurally that is conveyed visually during programming
other than newscasts,” the document states. “Second, we seek comment… on how to
ensure that television apparatus are able to make available video description,
as well as to make emergency information, accessible to individuals who are
blind or visually impaired.”
The NPRM seeks comment on the incremental costs of providing a secondary audio
stream to convey emergency information. It asks if the new rules should be
applied differently to broadcasters or multichannel video providers who may not
have a secondary audio stream and lack the technical capability to pass through
video description information. The 2011 Video Description Order, which compels
large-market stations to provide aural description of regular
programming—contains a technical capability exception. The NRPM asks if there
are alternatives to using secondary audio for provision of video description.
It also asks for feedback on how the scheme would affect channel-sharing, which
is a large part of the commission’s incentive auction proposal.
While the emergency information referenced in the NPRM is not limited to
Emergency Alert System notifications, they are mentioned.
“We seek comment on whether and how the proposals contained herein should apply
to EAS alerts,” it states. “For example, to what extent is emergency
information provided as visual-only EAS alerts?”
The commission has until April 9, 2013 to complete the proceeding on
access to emergency information, and until Oct. 9, 2013, to complete receiver requirements.
The deadline for comments will be 20 days after publication in the Federal
Register. The Docket No. is 12-107.
