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.
