Overview

The hybrid digital and analog broadcasting solution deployed in the United States, FM and AM IBOC, more commonly known as HD Radio*, allows simultaneous transmission of broadcast radio signals in both the analog and digital domain. A key component is that receivers can immediately acquire the analog signal and then transition (or blend) into the digital signal after it has acquired and buffered. Audible blending artifacts are the top HD Radio complaint from auto manufacturers and consumers. The majority of the problems can be traced back to individual broadcast stations. The industry has long relied on manual management of diversity delay and time alignment. However, the results in the field often have shown us that stations set manually have been known to drift over time. This presentation will cover some of the causes of drift and how those can be resolved. However, we have learned there are a myriad of potential problems that can cause drift that are out of control of any individual device that has been traditionally installed in the broadcast chain. What is needed is a systems approach to this problem. This presentation will discuss implementing various combinations of hardware and/or software to provide continuous monitoring and adjustment of diversity delay in real-time to reduce or eliminate the objectionable blending artifacts impacting listeners.
