Methods and apparatus for presenting substitute content in an audio/video stream using text data
View Patent ↗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.
1. A method for processing a first audio/video stream having at least one segment of a show, at least one interstitial of the show, and closed captioning data associated with the show, the method comprising:
receiving autonomous location information separately from the first audio/video stream, the autonomous location information comprising a first unique text string, a second unique text string, a first forward offset associated with the first unique text string, a first backward offset associated with the first unique text string, a second forward offset associated with the second unique text string, and a second backward offset associated with the second unique text string;
processing the closed captioning data to identify the first unique text string; determining that the first unique text string is not located within the closed captioning data;
in response to determining that the first unique text string is not located within the closed captioning data, processing the closed captioning data again to identify the second unique text string;
determining that the second unique text string is located within the closed captioning data; and
in response to determining that the second unique text string is located within the closed captioning data, utilizing the second forward offset and the second backward offset to specify a beginning boundary of a segment of the show and an ending boundary of the segment of the show.
2. The method of claim 1 , further comprising: identifying a first video location within the first audio/video stream, the first video location corresponding to the beginning boundary; and identifying a second video location within the first audio/video stream, the second video location corresponding to the ending boundary.
3. The method of claim 1 , further comprising:
identifying substitute content to present in association with the segment of the show; and
outputting a second audio/video stream for presentation on a display device, the second audio/video stream including the segment of the show and the substitute content.
4. The method of claim 3 , wherein outputting the second audio/video stream comprises replacing the at least one interstitial of the show with the substitute content.
5. The method of claim 1 , wherein:
the first forward offset and the first backward offset are each specified relative to a beginning of the first unique text string; and
the second forward offset and the second backward offset are each specified relative to a beginning of the second unique text string.
6. A receiving device comprising:
a communication interface that receives a first audio/video stream including at least one segment of a show, at least one interstitial of the show, and closed captioning data associated with the first audio/video stream;
a storage unit that stores the first audio/video stream and the closed captioning data;
control logic that:
receives autonomous location information separately from the first audio/video stream, the autonomous location information comprising a first unique text string, a second unique text string, a first forward offset associated with the first unique text string, a first backward offset associated with the first unique text string, a second forward offset associated with the second unique text string, and a second backward offset associated with the second unique text string;
reviews the closed captioning data to locate the first unique text string;
determines that the first unique text string is not located within the closed captioning data;
in response to determining that the first unique text string is not located within the closed captioning data, reviews the closed captioning data again to locate the second unique text string;
determines that the second unique text string is located within the closed captioning data; and
in response to determining that the second unique text string is located within the closed captioning data, utilizes the second forward offset and the second backward offset to specify a beginning boundary of a segment of the show and an ending boundary of the segment of the show;
identifies substitute content to present in association with the segment of the show; and
an audio/video interface that outputs a second audio/video stream for presentation on a display device, the second audio/video stream including the segment of the show and the substitute content.
7. The receiving device of claim 6 , wherein the control logic sorts the closed captioning data according to a presentation order of the closed captioning data and stores the sorted closed captioning data in a data file separate from the first audio/video stream.
8. The receiving device of claim 6 , wherein the audio/video interface replaces the at least one interstitial with the substitute content when outputting the second audio/video stream.
9. The receiving device of claim 6 , wherein the audio/video interface outputs the substitute content before the segment of the show in the second audio/video stream.
10. The method of claim 6 , wherein:
the first forward offset and the first backward offset are each specified relative to a beginning of the first unique text string; and
the second forward offset and the second backward offset are each specified relative to a beginning of the second unique text string.
