The Institute of Electrical and Electronics Engineers holds its annual Broadcast Symposium in San Antonio this week. And if I could be there, I’d be hitting up the last session of Thursday afternoon, for there may be a few fireworks.
There are two planned speakers: first up is David Layer, the Director of NAB Labs’ Radio Technology Committee, who will give a status report on the state of all-digital AM-HD signal testing. The most recent round concluded in Seattle, and depending on who you ask, the results were either spectacular or so-so. Continue reading “NAB v. DPR: Showdown in San Antonio?”

The Limits of "Authorized" Innovation: Settling the DPR Dilemma
Last month’s stalemate between iBiquity Digital Corporation, the proprietor of HD Radio, and upstart-innovator Digital PowerRadio appears to have been broken.
For those just tuning in: DPR claims to have invented a process that can make HD receivers much more sensitive, allowing for better reception of digital radio signals. iBiquity asserts that DPR’s method is outdated and meaningless. Since iBiquity owns all aspects of HD Radio, it also controls the code necessary to verify or debunk DPR’s claims. Continue reading “The Limits of "Authorized" Innovation: Settling the DPR Dilemma”
Digital PowerRadio Dispute: The Downside of Closed Systems
There’s been an interesting story playing itself out over the last month involving a company’s claims of discovering a way to dramatically improve reception of HD Radio signals.
Florida-based DigitalPower Radio announced in late March that it has developed a computational method that allows radio receivers a stronger lock on AM- and FM-HD signals, especially in areas where there might be analog-to-digital interference. Challenging conditions such as these have been detrimental to the robustness of HD signals more generally, for which the (FM) power increase implemented by some stations a couple of years ago only partially helped.
This improvement might be especially helpful in portable and mobile devices, as the change is made on a chip in the HD receiver, not on the transmission side. Continue reading “Digital PowerRadio Dispute: The Downside of Closed Systems”
