West Chester, PA (March 20, 2015)—Belar Electronics will showcase Automatic Delay Correction, a method for radio broadcasters to eliminate delay between digital and analog signals on the fringes of HD Radio coverage, at the 2015 NAB Show.
The software-defined feature adjusts the time alignment, reportedly eliminating the roughly eight-second delay between the HD main and analog FM programming. In areas where HD Radio coverage is less robust, this allows switching back and forth between the two programs without audience detection, according to the company.
Belar will demonstrate Automatic Delay Correction in its FMHD-1 modulation monitor at its NAB booth 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.
