Abstract
A system, computer-readable storage medium storing at least one program, and a computer-implemented method for identifying computer systems being used by viewers of television programs is presented. An audio signal received from a microphone of a television metering device is monitored, where the audio signal corresponds to audio of a television program presented on the television set and audio tones generated by computer systems of viewers of the television set. The audio signal is analyzed to determine an identifier for the television program being presented on the television set and to identify an audio tone generated by a computer system of a viewer of the television set. An identifier of the computer system associated with the audio tone is determined. An identifier for the television metering device, the identifier for the television program, and the identifier of the computer system is transmitted to a server.
