West Chester, PA, March 17, 2015� At the 2015 NAB Show, Belar Electronics will showcase a simple and cost-effective way for radio broadcasters to eliminate delay between digital and analog signals on the fringes of HD Radio� coverage. Branded as Automatic Delay Correction, the software-defined feature consistently adjusts the time alignment, eliminating the roughly eight-second delay between the HD main and analog FM programming. This ensures a pleasant listening experience for audiences in areas where HD Radio coverage is less robust, seamlessly switching back and forth between the two programs without audience detection.
Belar accomplishes this important task without forcing its customers to push the audio through the modulation monitor. Instead, Belar�s Automatic Delay Correction for time alignment feeds the adjustment back toward the front of the air chain, with corrections taking place in the audio processor, precision delay or exporter. This is a significant innovation, as it keeps costs lower for the broadcaster while eliminating a redundancy in the air chain.
�Every HD Radio broadcaster already has a delay line built into the air chain, whether it�s through the leading audio processors on the market or within a current generation exporter,� said Mark Grant, CEO, Belar Electronics. �We are removing an unnecessary step by feeding the signal back to the processor or exporter. Our modulation monitors require only a simple software upgrade in the field, ensuring that broadcasters can seamlessly incorporate time alignment without significant costs or complexity.�
Belar will demonstrate Automatic Delay Correction in its FMHD-1 modulation monitor at its NAB booth (C2452, April 13-16 at the Las Vegas Convention Center), with additional demos on the exhibit floor to be confirmed. The demos will detail how Automatic Delay Correction establishes a connection to an audio processor or exporter, measures the signal error and communicates the necessary adjustment to the delay line. That communication is locked into in a continuous loop, ensuring that the appropriate time delay is constant and consistent.
