1. A method comprising:
detecting, by one or more processors, a control signal communicated by a first device to a second device, the control signal causing the second device to select a data stream from a plurality of data streams;
accessing, by one or more of the processors, an output signal resultant from the second device in processing the data stream;
generating, by one or more of the processors, a representation of the output signal;
obtaining, by one or more of the processors, an identifier of a source of the data stream based on a comparison of the generated representation of the output signal to a reference representation that corresponds to the data stream; and
assigning, by one or more of the processors, the identifier of the source of the data stream to the control signal that caused the second device to select the data stream.
