1. An arrangement comprising:
- a memory containing stored sound representations;
an audio signal monitoring device that monitors a broadcast audio signal for the presence of the stored sound representations in the broadcast audio signal;
a processor responsive to detection of the stored sound representations in the broadcast audio signal by the audio signal monitoring device to perform a control function;
said processor including a means for generating a universal resource locator as a result of an analysis of the broadcast audio signal.

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.

12. A system comprising:
-
a display receiving a video broadcast signal and an audio broadcast signal; a sound recorder that cyclically records the audio broadcast signal for a first period of time, and is responsive to a control signal to continue recording of the audio broadcast signal for a second period of time in addition to the first period of time to create a sound clip of the audio broadcast signal that has a length equal to the first period of time plus the second period of time; a keyword listening device that monitors the audio broadcast signal and generates the control signal in response to detection of a keyword in the audio broadcast signal; a processor that analyzes the sound clip and controls an action by the system as a function of the analyzed sound clip; and a network port for connecting the system to an external network. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of responding to a broadcast audio signal, comprising the steps of:
-
receiving an audio signal; cyclically recording a sound clip loop of the audio signal; monitoring for the presence of keywords in the audio signal; recording the audio signal for a period of time upon detection of a keyword in the audio signal to generate an addition to the sound clip loop, the sound clip loop and the addition forming a sound clip; analyzing the sound clip; performing a control function in dependence upon the analyzed sound clip; and forming an external network address during said control function. - View Dependent Claims (20, 21)
