ABSTRACT:
A method and arrangement for monitoring the audio portion of a broadcast signal includes a keyword listening device. A relatively limited set of keywords are stored in a memory and the keyword listening device monitors the broadcast signal for any of these keywords. Upon recognition of any one or more of the keywords, the broadcast audio signal is recorded for a period of time and then fully analyzed. After analysis, and in dependence upon the recorded and analyzed broadcast audio signal, a number of different functions, such as connection to an external network at a specified address, or control of a video cassette recorder, may be performed.
