System and method for identifying computer systems being used by viewers of television programs

A system to identify computer systems being used by viewers of television programs, comprising:

• at least one processor;
• memory;
• and
• at least one program stored in the memory and executable by the at least one processor, the at least one program comprising instructions to:
• monitor an audio signal received by a microphone of a television metering device, the audio signal corresponding to audio of a television program presented on the television set, at least one audio tone generated by at least one audio transmitter of at least one viewer of the television set, and at least one audio tone generated by at least one computer system in use by at least one viewer of the television set;
• analyze the audio signal to determine an identifier for the television program being presented on the television set;
• analyze the audio signal to identify a first audio tone generated by an audio transmitter of a viewer of the television set;
• analyze the audio signal to identify a second audio tone generated by the at least one computer system in use by the viewer of the television set;
• determine an identifier of the viewer corresponding to the first audio tone identified by analyzing the audio signal;
• determine an identifier of the computer system corresponding to the second audio tone and an identifier of the viewer encoded in the second audio tone, identified by analyzing the audio signal;
• and
• transmit an identifier for the television metering device, the identifier for the television program, the identifier of the viewer corresponding to the first audio tone, and the identifier of the computer system to a server.

A non-transitory computer readable storage medium storing at least one program configured for execution by at least one processor of a computer system, the at least one program comprising instructions to:

• monitor an audio signal received by a microphone of a television metering device, the audio signal corresponding to audio of a television program presented on the television set, at least one audio tone generated by at least one audio transmitter of at least one viewer of the television set, and at least one audio tone generated by at least one computer system in use by at least one viewer of the television set;
• analyze the audio signal to determine an identifier for the television program being presented on the television set;
• analyze the audio signal to identify a first audio tone generated by an audio transmitter of a viewer of the television set;
• analyze the audio signal to identify a second audio tone generated by the at least one computer system in use by the viewer of the television set;
• determine an identifier of the viewer corresponding to the first audio tone identified by analyzing the audio signal;
• determine an identifier of the computer system corresponding to the second audio tone and an identifier of the viewer encoded in the second audio tone, identified by analyzing the audio signal;
• and
• transmit an identifier for the television metering device, the identifier for the television program, the identifier of the viewer corresponding to the first audio tone, and the identifier of the computer system to a server.
