摘要 <p>Various embodiments of apparatus and/or methods are described for skipping, filtering and/or replacing content from an audio/video stream using text data associated with the audio/video stream. The text data is processed using location information that references a segment of the text data of the first audio/video stream to identify a location within the first audio/video stream. The location within the first audio/video stream is utilized to identify portions of the audio/video stream that are to be skipped during presentation. The portions of the audio/video stream that are to be skipped are filtered from the audio/video stream, and some of the skipped portions of the audio/video stream are replaced with substitute content. The filtered video stream, including the substitute content, is outputted for presentation to a user.</p>
