Arbitron: PPMs Track HD Radio

Arbitron has announced that its portable people meter (PPM) system can track HD radio technology, including its separately encoded sub-channels. The trials took place the week of July 28 on the digital channels of a radio station in one of the top ten metros; Arbitron did not release the name of the radio station.

Arbitron tested the PPM system with HD Radio technology to determine if separately encoded sub-channels could be tracked by its portable audience measurement system. The trials showed that separately encoded multicast channels did not conflict with the main channel’s encoding.

 

“With the PPM, each distribution stream can have a unique identification code. If a listener hears it, the PPM can identify it with near-perfect certainty,” said Pierre Bouvard, president, Portable People Meter, Arbitron Inc.

Arbitron announced earlier this week that PPMs could successfully track podcasts, as well.
