The IBOC system for FM as developed by Ibiquity is a fascinating engineering feat.
IBOC has been officially launched, but what do we do with the data capacity?
Despite the hiatus in nighttime operation for AM IBOC, antenna research is continuing in an effort to comply with the FCC's existing requirements of two antennas for FM IBOC, and develop a system using one antenna that will satisfy the FCC's requirements.
It appears the Ibiquity team has found a good solution to the audio encoding problem.
With the FM implementation of IBOC, standard broadcast stations will need to deal with a number of technical problems related to making IBOC work with RF propagation issues.
10 steps to determining the best digital migration path.
New technology can be described as either emerging or breakthrough. IBOC is hardly breakthrough.
In the middle of May, the road to IBOC took a major detour. What has been an ongoing work in progress with a predictable slow and steady pace has been
WOR has encountered many positive results during its transition to IBOC. These tests were used to gather data on nighttime interference.
The FCC has selected in-band on-channel (IBOC) as the digital radio broadcast technology of choice for AM and FM--what does this mean to you?
The introduction of Ibiquity IBOC-capable radios is slated for the January 2003 CES, so let's review the information at hand so that you know how IBOC works.
Entercom, Shively and Broadcast Electronics work together on an alternate method of hybrid IBOC generation.
The Commission is on the verge of approving the Ibiquity standard, but serious questions still exist as to the value of the system to broadcasters and whether a full-time AM system will ever work.
Already 10 years in the making, in-band on-channel digital audio broadcasting has promised to be the next evolution of terrestrial radio; an evolution that would carry the radio industry through the next 100 years.
Some transmitter manufacturers have already announced the availability of FM IBOC transmitting equipment, and offered actual equipment at the NAB show. FM IBOC requires considerably more equipment than the AM version, and it is more expensive.
Many engineers anxiously awaited the release of the National Radio Systems Committee's AM IBOC Report, in hopes that the report would reveal good news about AM IBOC.
IBOC has been designed to occur simultaneously with the station's existing analog transmission and within the existing spectrum allocation.
As IBOC gets closer to being a reality, radio stations are starting to see the light ahead. This light is not just the promise of an improved service, but also the realization that nothing in life is free.
Ibiquity's IBOC system has been designed to support the broadcast of data services in all modes of operation.
At the end of November, the National Radio Systems Committee released its report recommending that the FCC authorize Ibiquity Digital Corporation's FM In-band On-channel digital radio broadcast technology as an enhancement to the current analog FM broadcasting system in the United States.
The single largest factor in the cost of an IBOC conversion, the transmitter, is the subject of the majority of inquiries.
Ibiquity has completed tests for its FM IBOC system, and tests for the AM version are currently underway. What interests most broadcasters is understanding the test objectives. At this critical point in the acceptance of IBOC, stations should be aware of the efforts being made to develop a workable and realistic system.
The NRSC's recommendation to the FCC is the result of a comprehensive test program devised and executed by the committee to determine the viability of iBiquity's FM IBOC technology and its ability to smoothly transition analog radio to digital.
The event will take place on Saturday, December 1, 2001, at 9 a.m.
The article titled "Transmission: Implementing IBOC" in the October 2001 issue of BE Radio is very informative, but one concept in it may need further clarification.
