Identifying optimal thumbnail images for video search hitlist

摘要

A video database is indexed using the terms of closed-captioning which accompany the video components of the video database. When a query is run against the video database, a list of hits, corresponding to video components relevant to the query, are presented to the user by selecting a representative image from each video component in the hitlist and presenting the representative images to the user in an array of thumbnail images with the corresponding closed-captioned text.
