Scalable, adaptable, and manageable system for multimedia identification
First Claim
1. A method for query caching, the method comprising:
- generating signatures of a video content at a client, wherein the signatures are split into blocks of signatures and each block of signatures represents a non-overlapping segment of the video content;
generating a hash key from each block of signatures at the client, wherein a sequence of hash keys are generated at the client;
requesting a search of a remote reference database using the sequence of hash keys;
searching the remote reference database for a match with the sequence of hash keys to find search results for a match with at least one hash key of the sequence of hash keys;
sending to the client the search results linked with a matching hash key, wherein the results were generated from a previous full search of the remote reference database; and
storing the search results in a cache at the client, wherein the search results are accessible from the cache using the at least one hash key.

Abstract
An architecture for a multimedia search system is described. To perform similarity matching of multimedia query frames against reference content, reference database comprising of a cluster index using cluster keys to perform similarity matching and a multimedia index to perform sequence matching is built. Methods to update and maintain the reference database that enables addition and removal of the multimedia contents, including portions of multimedia content, from the reference database in a running system are described. Hierarchical multi-level partitioning methods to organize the reference database are presented. Smart partitioning of the reference multimedia content according to the nature of the multimedia content, and according to the popularity among the social media, that supports scalable fast multimedia identification is also presented. A caching mechanism for multimedia search queries in a centralized or in a decentralized distributed system and a client based local multimedia search system enabling multimedia tracking are described.
