Abstract:
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.
