Abstract

Described herein are methods and apparatus for the identification of locations in a presentation stream based on metadata associated with the presentation stream. Locations within a presentation stream are identified using location information and/or signature data associated with the presentation stream. The identified locations within a presentation stream may be utilized to identify boundaries of segments within the presentation stream, such as segments of a show. The boundaries of the segments may then be utilized to change the volume of segments or playback a segment at a non-real time presentation rate.

Claims

1. A method for processing an audio/video stream, the method comprising:

providing an audio/video stream including at least one segment of a show, at least one interstitial of the show and closed captioning data;

receiving location information referencing the closed captioning data to identify a video location within the audio/video stream;

receiving at least one off-set specified relative to the video location;

processing the audio/video stream to identify boundaries of the at least one segment of the show based on the location information and the off-set;

outputting the segment of the show for presentation by a display device;

modifying a volume of audio data corresponding with the interstitial; and

outputting the modified volume interstitial for presentation by the display device.

2. The method of claim 1, wherein modifying the volume of the audio data further comprises:

muting the volume of the audio data corresponding with the interstitial.

3. The method of claim 1, wherein receiving the location information and the at least one off-set further comprise:

receiving the location information, in association with the off-set, separately from the audio/video stream.

4. The method of claim 3, further comprising:

receiving a signature of a portion of the audio/video stream associated with the video location;

wherein processing the audio/video stream to identify the boundaries is further based on processing of the signature.

5. The method of claim 4, wherein the location information includes at least one text string contained in the closed captioning data that is associated with the video location, beginning and ending offsets, associated with the text string, that are specified relative to the video location, the beginning and ending offsets identifying beginning and ending locations of the at least one segment, and wherein processing the audio/video stream further comprises:

processing the closed captioning data to identify an intermediate location within the audio/video stream corresponding with presentation of the text string;

processing the audio/video stream to identify the video location based on the signature;

determining an adjustment offset between the intermediate location and the video location;

adjusting the beginning and ending offsets based on the adjustment offset; and

identifying the beginning location and the ending location of the at least one segment in the audio/video stream based on the adjusted beginning and ending offsets.

6. A method for processing an audio/video stream, the method comprising:

providing an audio/video stream including at least one segment of a show, at least one interstitial of the show and closed captioning data;

receiving location information referencing the closed captioning data to identify a video location within the audio/video stream;

receiving at least one off-set specified relative to the video location;

processing the audio/video stream to identify boundaries of the at least one segment of the show based on the location information and the off-set;

outputting the segment of the show at a first presentation rate for presentation by a display device; and

outputting the interstitial of the show at a second presentation rate for presentation by the display device.

7. The method of claim 6, wherein the second presentation rate is greater than the first presentation rate.

8. The method of claim 6, wherein receiving the location information and the at least one off-set further comprise:

receiving the location information, in association with the off-set, separately from the audio/video stream.

9. The method of claim 6, further comprising:

receiving a signature of a portion of the audio/video stream associated with the video location;

wherein processing the audio/video stream to identify the boundaries is further based on processing of the signature.

10. The method of claim 9, wherein the location information includes at least one text string contained in the closed captioning data that is associated with the video location, beginning and ending offsets, associated with the text string, that are specified relative to the video location, the beginning and ending offsets identifying beginning and ending locations of the at least one segment, and wherein processing the audio/video stream further comprises:

processing the closed captioning data to identify an intermediate location within the audio/video stream corresponding with presentation of the text string;

processing the audio/video stream to identify the video location based on the signature;

determining an adjustment offset between the intermediate location and the video location;

adjusting the beginning and ending offsets based on the adjustment offset; and

identifying the beginning location and the ending location of the at least one segment in the audio/video stream based on the adjusted beginning and ending offsets.

11. A digital video recorder comprising:

a communication interface that receives an audio/video stream including at least one segment of a show, at least one interstitial of the show and closed captioning data;

a storage medium;

control logic communicatively coupled to the communication interface and the storage medium that;

coordinates storage of the audio/video stream onto the storage medium;

receives location information referencing the closed captioning data to identify a video location within the audio/video stream and at least one off-set specified relative to the video location; and

processes the recorded audio/video stream to identify boundaries of the at least one segment of the show based on the location information and the off-set;

an audio/video interface communicatively coupled to the control logic that outputs the segment of the show for presentation by a display device, modifies a volume of audio data corresponding with the interstitial and outputs the modified volume interstitial for presentation by the display device.

12. The digital video recorder of claim 11, wherein the audio/video interface mutes the volume of the audio data corresponding with the interstitial.

13. The digital video recorder of claim 11, wherein the control logic receives the location information, in association with the off-set, separately from the audio/video stream.

14. The digital video recorder of claim 13, wherein the control logic is further operable to receive a signature of a portion of the audio/video stream associated with the video location and process the audio/video stream to identify the boundaries based on the signature, the location information and the off-set.

15. The digital video recorder of claim 14, wherein the location information includes at least one text string contained in the closed captioning data that is associated with the video location, beginning and ending offsets, associated with the text string, that are specified relative to the video location, the beginning and ending offsets identifying beginning and ending locations of the at least one segment, and wherein the control logic is further operable to:

process the closed captioning data to identify an intermediate location within the audio/video stream corresponding with presentation of the text string;
