发明名称 Content indexing and searching using content identifiers and associated metadata
摘要 A method of indexing content for network searching comprises obtaining media content signals stored on a computer network; deriving content identifiers from the content signals; using the content identifiers to obtain metadata used to classify the media content signals; and creating a searchable index of the media content signals based on the metadata, wherein users access the searchable index on the distributed computer network to submit a search query for the searchable index to retrieve links to the media content signals.
