About SPI

(Sample Performance Indicator) SPI is a longitudinal response metric for electronic panels that measure radio and television. For PPM, the average daily persons SPI each month shows the percent of total persons in the original, pre-designated random sample who have provided fault free data for at least eight hours on a given day (five hours among persons aged 6-17). SPI is calculated for each of the 28 days in a PPM survey and it is averaged for the reporting period.

About Designated Delivery Index

Designated Delivery Index or DDI is the actual sample size for a given demographic divided by the target sample size for the demographic (multiplied by 100). A DDI of 100 means that Arbitron achieved its sample target; a DDI of greater than 100 means that Arbitron exceeded its sample goal.

About the Portable People Meter

The Arbitron Portable People Meter(TM) system uses a passive audience measurement device - about the size of a small cell phone - to track consumer exposure to media and entertainment, including broadcast, cable and satellite television; terrestrial, satellite and online radio as well as cinema advertising and many types of place-based electronic media. Carried throughout the day by randomly selected survey participants, the PPM(TM) device can track when and where they watch television, listen to radio as well as how they interact with other forms of media and entertainment.

The PPM detects inaudible codes embedded in the audio portion of media and entertainment content delivered by broadcasters, content providers and distributors. At the end of the day, the meter is placed in a docking station that extracts the codes and sends them to a central computer. The PPM is equipped with a motion sensor, a patented quality control feature unique to the system, which allows Arbitron to confirm the compliance of the PPM survey participants every day.
