Abstract
A method of indexing content for network searching comprises identifying media content signals stored at sites distributed over a distributed computer network; extracting 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.
Claims14
A method for processing media content on a distributed network, the method comprising:
- identifying media content signals stored at sites distributed over the distributed computer network;
- extracting 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.
A method for searching for audio or images on a distributed computer network comprising:
- from a location in the distributed computer network, receiving a query for content signals related to a first content signal, the first content signal being part of the query;
- receiving a content identifier extracted from audio or image data of the first content signal;
- using the content identifier to obtain metadata used to classify the first content signal;
- searching a searchable index of media content signals based on the metadata, which forms search criteria for the first content signal;
- and
- returning a set of search results including references to content signals stored in the distributed computer network that correspond to the search criteria.
