1. A method for filtering a video stream, the method comprising:
- receiving a video stream including at least one segment of a show, at least one interstitial of the show, and closed captioning data associated with the video stream;
receiving metadata referencing the closed captioning data to identify first and second anchor frames within the video stream, the metadata comprising first and second displayable text strings included within the closed captioning data as originally transmitted by a content provider;
parsing the closed captioning data associated with the video stream to locate the first anchor frame corresponding with the presentation of the first displayable text string located in the closed captioning data recorded;
determining that the first displayable text string is not located within the closed captioning data recorded;
processing the closed captioning data recorded to locate the second anchor frame corresponding with the presentation the second displayable text string in the closed captioning data recorded;
identifying the boundaries of the at least one segment of the show based on the second anchor frame and the metadata;
filtering the at least one interstitial from the video stream based on the identified boundaries to generate a filtered video stream; and
presenting the filtered video stream to a user.

Abstract
Various embodiments of apparatus and/or methods are described for skipping and/or filtering content from a video stream using text data associated with the video stream. The text data is parsed using metadata to identify portions of the video stream to skip during presentation, and/or to identify portions of the video stream to present to a user. The portions of the video stream that are to be skipped are filtered from the video stream, and the filtered video stream is presented to a user.
