Harker: PPM Encoding Accuracy Questioned

The decoding accuracy of PPM is being challenged at the NAB, where TELOS ALLIANCE Omnia Team Leader CORNELIUS GOULD spoke at the SUNDAY Radio Technology Forum. In the new Radio Insights column, HARKER RESEARCH concludes that “radio has not done enough to make sure PPM meters properly register station listening, as GOULD “shared test results illustrating how gaps in PPM station encoding levels can potentially cost stations quarter-hours of listening.
“One potential problem is programming material with weak mid-range content. GOULD singled out older Hip-Hop played by Urban ACs as an example. High ambient interference such as highway noise can also have a negative impact on PPM decoding. Improper processing is a third source of lost quarter-hours.”
