Signal processing apparatus, signal processing method, signal processing program, program reproducing apparatus, image display apparatus and image display method

A signal processing apparatus comprising:

• an audio signal detection circuit which detects a plurality of audio signals;
• and
• a control unit which controls an interface of a peripheral device,
• wherein said audio signal detection circuit generates a control signal for controlling said control unit when said audio signal detection circuit detects the plurality of specific audio signals within a predetermined time, and
• wherein said control unit selectively performs predetermined control for the peripheral device according to the plurality of specific audio signals.

A signal processing method comprising:

• an audio signal detection step of detecting a specific audio signal from a broadcasting program including an image signal and an audio signal;
• and
• a control step of controlling an image processing processor by a control unit,
• wherein said audio signal detection step generates a control signal for controlling the control unit when the audio signal is detected, and
• wherein said control step controls the image processing processor according to the control signal so as to display a specific image and/or text by synthesizing the specific image and/or text corresponding to the specific audio signal and an image of the broadcasting program displayed according to the image signal.

A signal processing method comprising:

• an audio signal detection step of detecting a plurality of audio signals;
• and
• a control step of controlling an interface of a peripheral device by a control unit,
• wherein an audio signal detection step generates a control signal for controlling the control unit when the plurality of specific audio signals are detected within a predetermined time, and
• wherein said control step selectively performs predetermined control of the peripheral device according to the plurality of specific audio signals.

A signal processing program executing:

• an audio signal detection step of detecting a specific audio signal from a broadcasting program including an image signal and an audio signal;
• and
• a control step of controlling an image processing processor by a control unit,
• wherein said audio signal detection step generates a control signal for controlling the control unit when the audio signal is detected, and
• wherein said control step controls the image processing processor according to the control signal so as to display a specific image and/or text by synthesizing the specific image and/or text corresponding to the specific audio signal and an image of the broadcasting program displayed according to the image signal.

A signal processing program which causes a computer to execute:

• an audio signal detection step of detecting a plurality of audio signals;
• and
• a control step of controlling an interface of a peripheral device by a control unit,
• wherein said audio signal detection step generates a control signal for controlling the control unit when the plurality of specific audio signals are detected within a predetermined time, and
• said control step selectively performs predetermined control of the peripheral device according to the plurality of specific audio signals.

An image display apparatus comprising:

• output means for outputting an image and an audio;
• pattern registering means for causing a user to register a pattern including the image, the audio, or a combination thereof;
• action designation means for causing the user to designate an action performed in association with the registered pattern;
• determination means for determining whether the pattern is included in the inputted image signal or audio signal or not;
• and
• control means for outputting the stored image signal and audio signal to the output means when the pattern is not included, the control means causing the output means to perform the designated action when the pattern is included.
