Abstract

An example method is provided and includes receiving a video bitstream in a network environment; detecting a question in a decoded audio portion of a video bitstream; and marking a segment of the video bitstream with a tag. The tag may correspond to a location of the question in the video bitstream, and can facilitate consumption of the video bitstream. The method can further include detecting keywords in the question, and combining the keywords to determine a content of the question. In specific embodiments, the method can also include receiving the question and a corresponding answer from a user interaction, crowdsourcing the question by a plurality of users, counting a number of questions in the video bitstream and other features.

Claims (59)

1. A method, comprising:

receiving a video bitstream in a network environment;

decoding an audio portion of the video bitstream;

automatically detecting a question in the decoded audio portion of the video bitstream;

marking a segment of the video bitstream with a tag corresponding to a location of the automatically detected question in the video bitstream, wherein the tag can facilitate consumption of the video bitstream;

receiving a search query seeking the automatically detected question; and

returning the segment marked with the tag.

2. The method of claim 1 , further comprising:

detecting keywords in the question; and

combining the keywords to determine a content associated with the question.

3. The method of claim 1 , further comprising:

receiving the question and a corresponding answer from a user interaction.

4. The method of claim 3 , further comprising:

attaching at least one of an audio file and a video file to the video bitstream at the location of the question, wherein the audio file and the video file are associated with the corresponding answer.

5. The method of claim 1 , further comprising:

crowdsourcing the question by a plurality of users.

6. The method of claim 1 , further comprising:

correlating the question to other questions with similar keywords; and

returning a plurality of segments corresponding to the question and the other questions.

7. The method of claim 6 , further comprising:

correlating an answer to the question to one or more other answers; and

returning another plurality of segments corresponding to the answer and the one or more other answers.

8. The method of claim 1 , further comprising:

counting a number of questions in the video bitstream.

9. The method of claim 1 , further comprising:

encoding the marked segment as an I-frame.

10. Logic encoded in non-transitory media that includes instructions for execution and when executed by a processor, is operable to perform operations comprising:

receiving a video bitstream in a network environment;

decoding an audio portion of the video bitstream;

automatically detecting a question in the decoded audio portion of the video bitstream;

marking a segment of the video bitstream with a tag corresponding to a location of the automatically detected question in the video bitstream, wherein the tag can facilitate consumption of the video bitstream;

receiving a search query seeking the automatically detected question; and

returning the segment marked with the tag.

11. The logic of claim 10 , the operations further comprising:

detecting keywords in the question; and

combining the keywords to determine a content associated with the question.

12. The logic of claim 10 , the operations further comprising receiving the question and a corresponding answer from a user interaction.

13. The logic of claim 10 , the operations further comprising crowdsourcing the question by a plurality of users.

14. The logic of claim 10 , the operations further comprising:

counting a number of questions in the video bitstream.

15. An apparatus, comprising:

a memory element for storing data;

a processor that executes instructions associated with the data;

an analyzer configured to interface with the processor and the memory element such that the apparatus is configured for:

receiving a video bitstream in a network environment;

decoding an audio portion of the video bitstream;

automatically detecting a question in the decoded audio portion of the video bitstream;

marking a segment of the video bitstream with a tag corresponding to a location of the automatically detected question in the video bitstream, wherein the tag can facilitate consumption of the video bitstream;

receiving a search query seeking the automatically detected question; and

returning the segment marked with the tag.

16. The apparatus of claim 15 , wherein the apparatus is further configured for:

detecting keywords in the question; and

combining the keywords to determine a content associated with the question.

17. The apparatus of claim 15 , wherein the apparatus is further configured for:

receiving the question and a corresponding answer from a user interaction.

18. The apparatus of claim 15 , wherein the apparatus is further configured for:

crowdsourcing the question by a plurality of users.

19. The apparatus of claim 15 , wherein the apparatus is further configured for:

counting a number of questions in the video bitstream.
