The station was the first AM station in Seattle to transmit its signal in IBOC digital radio during a joint demonstration with Harris Corporation and iBiquity, the licensee of the new digital AM transmission method.

Stations using iBiquity Digital Corporation's " HD Radio " system are contractually required to delay their analog broadcast by about eight seconds so it remains in sync with the digital stream.

iBiquity also created a mediumwave HD Radio system for AM, which is the only system approved by the Federal Communications Commission for digital AM broadcasting in the United States.

The IBOC system allows transmission of an audio frequency range extending to approximately 15 kHz, 2-ch Stereo on the AM band, but with significant digital artifact and aliasing due to substantial codec inadequacy, which is further complicated due to proprietary nature of the company, iBiquity, which not only sells and licenses the associated equipment to broadcasters, but also maintains control over its deployment, use, and distribution.

However, audio compressed with this method led to complaints about poor sound quality, so in 2003 iBiquity combined it with an enhancer called SBR ( spectral band replication ) that improves audio quality at very low bit rates and branded the codec to HDC ( High-Definition Coding ).

Typical costs are at least several tens of thousands of dollars at the outset ( including transmitter, diplexer or antenna / feedline, and labor ), plus per-channel annual fees to be paid to iBiquity.

However, in January 2008 at the Consumer Electronics Show ( CES ) in Las Vegas iBiquity unveiled a prototype of a new portable receiver, roughly the size of a cigarette pack.

iBiquity Digital Corporation is a company formed by the merger of USA Digital Radio and Lucent Digital Radio, with the goal of creating an in-band on-channel ( IBOC ) digital radio system for the United States and around the world.

The first, and currently only, digital technology approved for use on AM and FM broadcast frequencies by the Federal Communications Commission in the United States, is the proprietary HD Radio system developed by iBiquity Digital Corporation, which transmits energy beyond the alloted ± 100 kHz FM channel.

There is a one-time license fee to iBiquity Digital, for the use of its intellectual property, as well as costs for new equipment which range from $ 50, 000 to $ 100, 000 US ( 2010 ) per station.

According to iBiquity Digital, holder of the HD Radio trademark, the " HD " in " HD Radio " does not stand for " High Definition " or " Hybrid Digital ".

An article on www. mediabuyerplanner. com, dated January 9, 2007 states " Emerson Radio Corp. has been granted a non-exclusive technology license from iBiquity Digital Corporation to produce and sell HD Radio digital audio receivers for the North American consumer electronics market.

Whereas the AAC ( Advanced Audio Coding ) family of codecs are publicly documented standards, the HDC codec exists only within the HD Radio system, and is an iBiquity trade secret.

In September 2002, the United States Federal Communications Commission approved the proprietary iBiquity in-band on-channel ( IBOC ) HD Radio system of digital audio broadcasting, which is meant to improve the audio quality of signals.

Instead, the IBOC system is named HD Radio and owned by a consortium of private companies that is called iBiquity.

NDS, a maker of digital media encryption technology, has a deal with iBiquity to provide HD Radio with an encrypted content-delivery system called RadioGuard.

WBAP transmitted iBiquity HD Radio ( digital ) during the daytime and when not airing sports programming, until abruptly ending the " HD " digital transmission in early December 2008.

As defined by iBiquity these channels could be sub-divided into CD-quality ( 100 kbit / s ), FM-quality ( 25-50 kbit / s ), AM-quality ( 12 kbit / s ), or Talk-quality ( 5 kbit / s ) channels.

Unlike the HD system iBiquity calls " hybrid digital " the CAM-D system truly is a direct hybrid of both analog and digital.

Based in Columbia, Maryland, with additional offices in Basking Ridge, New Jersey, and Pontiac, Michigan, iBiquity is a privately held, intellectual properties company, whose investors include global leaders in the technology, broadcasting, manufacturing, media and financial industries.

iBiquity is trying to get HDR chipsets into mobile phones by 2012.
