ADVANCED SEARCH FOR MEDIA CONTENT

摘要

Methods and systems for indexing and efficiently retrieving media content in a database use subtitle data of media content items, including subtitle text and timestamps, for indexing the items. A media server coupled to a communication network identifies keywords in the subtitle data, and stores the media content items in association with metadata including the keywords. When a search request for media content is received, a search for media content includes searching the metadata of the stored media content to identify media content items having subtitles matching the search request. In one example, keywords are translated into multiple languages to enable searching of the metadata in multiple languages. In another example, timestamp information included in the subtitle data is also included in the metadata so as to enable a search to return a time point within a media content item at which a keyword matches the search request.
