Abstract
A method for video content searching is provided. The method accesses video content and segments the video content into a plurality of frames. The method identifies one or more characteristics for at least a portion of frames of the plurality of frames and determines time frames for each characteristic of the one or more characteristics within the portion of the frames. The method generates frame keywords for the plurality of frames based on the one or more characteristics. The method assigns at least one frame keyword to each time frame within the portion of the frames and generates an index store for the video content. The index store is generated based on the frame keywords and assigning the at least one frame keyword to each frame. The index store includes the frame keywords and time frames assigned to the frame keywords.
