Benefits of technology

[0022] A fourth aspect of the invention involves a method of controlling playback of an audio presentation comprising: receiving an indication of at least one objectionable word; receiving an audio signal; storing the audio signal in a memory; processing the stored audio signal to determine whether the at least one objectionable word is present in the audio signal; and controlling an audio presentation of the audio signal as a function of the operation of processing. The operation of controlling may com...

Embodiment Construction

[0031] Aspects of the present invention involve a television receiver, cable or satellite set-top box, video cassette recorder, DVD player, or other such audio signal processing apparatus configured to receive or otherwise process an audio stream. In one particular implementation, the audio signal processing apparatus is configured to mute certain words, such as words considered objectionable to a particular listener / viewer, within the audio stream. An apparatus or method conforming to the present invention may provide a mechanism whereby a user may indicate various words as objectionable. One embodiment conforming to the present invention analyzes the close caption stream to detect the objectionable word or phrase, converts the close caption word to an audio representation, and then compares the audio representation of the close caption to the audio stream to identify the objectionable word in the audio stream. When the objectionable word is identified, embodiments of the invention...

Abstract

Apparatus and methods conforming to the present invention comprise a method of controlling playback of an audio signal through analysis of a corresponding close caption signal in conjunction with analysis of the corresponding audio signal. Objection text or other specified text in the close caption signal is identified through comparison with user identified objectionable text. Upon identification of the objectionable text, the audio signal is analyzed to identify the audio portion corresponding to the objectionable text. Upon identification of the audio portion, the audio signal may be controlled to mute the audible objectionable text.
