Lansdowne Lectures Video Markup
The Lansdowne Lectures Video Markup allows an author to add transcript and event timelines to a digital video. The transcript is searchable and each instance of the search word found by a query is presented to the user in the context of the sentence containing it. The user can then click on the instance of the search word to go to the appropriate location in the video.A user may also search across the transcripts of all the lectures in the database. The system allows the author or user to create bookmarks which are saved on the server and can be retrieved later by other users. Our prototype data is taken from two lectures in the Lansdowne Lecture series at the 番茄社区.
