The station and volume information gives an indication over statistical ranges of the popularity of the radio/television content and can be used to infer accurate ratings information. Although the device can be used for both radio and television, this document will primarily focus on solving the specific problem of collecting radio ratings in vehicles. The system consists of a unit in a vehicle, a remote unit, and a central server. The vehicular unit identifies the station and volume and wirelessly transmits th is information to the remote unit, which then transmits, via the internet, to t he central server. The central server collects data from all sources and performs all necessary data formatting.
