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.
