On Thursday, the Federal Communications Commission began a serious look at
digital audio broadcasting, a service that could provide enhanced sound
quality, improved radio signal reception and new products such as
datacasting, multiplexing and subscription services.
Digital audio broadcasts will compete with satellite radio services, which
deliver subscription-based offerings providing digital audio quality and
most channels in a commercial-free format.

Some radio stations are already broadcasting digital audio services using
iBiquity technology, a move approved by the FCC in 2002. During its meeting
Thursday, the commission moved on a "Further Notice of Proposed Rulemaking,"
seeking comments on what rule changes and amendments are necessary for
digital audio broadcasting services today.

Specifically, the FCC is seeking comment on how its existing public
interest, programming and operational rules should be applied to digital
audio broadcasts. And the commission wants input on policies it may adopt to
encourage broadcasters to convert from an analog-only service to a hybrid
analog/digital radio service, and eventually to an all-digital radio
service.

Commissioners praised the move into digital broadcasting. But one
commissioner, Democrat Michael Copps, said more work should be done
concerning the new service.

With the proposed rulemaking, "We ask about local programming requirements
and the extent to which they should include news or public affairs
programming. We address the obligation to provide emergency information to
the public and how digital radio can provide greater access to critical
information. And we seek comment generally on ways that broadcasters can use
digital technology to better and more fully meet the needs of their
communities," Copps said.

IBOC is the US digital broadcast standard. AM IBOC uses digital sidebands
spaced away from a standard AM channel. It takes up a very wide channel,
over 30 khz. I'm not aware of any plans to put AM IBOC on SW, and let's
hope that bandwidth hog never shows up there.

I doubt the FCC cares if the US SW broadcasters use DRM modulation. The FCC
hardly seems to know SW radio exists.
