Open Mic 

Every radio engineer has his favorite songs that he uses to adjust a station's processing or evaluate performance.

Slow and Steady HD Radio Rollout 

This graph shows that consumers will increase their investment in HD Radio-capable receivers over the next decade.

Practicalities of surround 

While the standard defines the basic operation of the trasnmission system, the enhanced functions of data, surround sound and multicast operation have yet to be fully defined.

Notes on NRSC-5 and IBOC 

When the FCC asked for comments on NRSC-5, we asked readers to share their thoughts with us also. The response was overwhelming.

Case Study: Installing multicast 

Broadcasters have sought the killer application for FM HD Radio, and at first glance it looked like program-service data was going to be it.

IBOC and data 

The real return of migrating to IBOC comes down to the simple fact that it levels the playing field.

Digital radio? What's that? 

Radio has its work cut out for it because HD Radio is the best-kept secret.

One step closer 

Let NRSC-5 determine the basic operation of the system, which it has done. The added features and enhancements are needed, but they can wait until the next standards-setting announcement.

Maximized data 

Data networks have extended beyond basic bit shuffling. They now have support applications for nearly every function of the station.

PADding the truth 

One obstacle in displaying PAD from an automation system is that the information entered into the system may not have been keyed in a form that is suitable for the public.

The extra bits in IBOC 

Data has always been a part of the IBOC plan, but it is just being recognized for its current and future capabilities.

Open Mic 

We asked two industry professionals about their station's data capabilities. Read what they said.

Digital Radio Glossary 

The data aspect of HD Radio includes lots of new terms and abbreviations. Here are some of the more common abbreviations and terms that you will likely encounter.

Standards in data 

An informal standard for data services is defined by ID3, which grew from the popularity of MP3 files and the desire to include information about the audio within the file.

Digitized and confused 

I steered the sales people at a couple of local electronics dealers to terrestrial, digital receivers without using the terms IBOC, HD Radio or the dreaded high-definition radio and was told the that the receivers did not exist, that stores had head units but not the receiver unit or that the store had no plans to carry these units.

IBOC's real return 

Perhaps the answer to the return on investment for IBOC lies in its ability to keep pace with the emerging services.

How Tomorrow Radio Works 

Supplemental audio is poised to be one of the first data services used in HD Radio and is a key differentiator from the current analog service.

Digital alternatives 

While a single digital transmission standard has not yet been adopted by the FCC, the industry has already begun moving to IBOC. Despite this, HD Radio isn't the only game in town.
