METHOD AND DEVICE FOR CONSTRUCTING ON-LINE REAL-TIME UPDATING OF MASSIVE AUDIO FINGERPRINT DATABASE

摘要

According to the present invention, a kind of method and apparatus are provided,For constructing a large amount of audio fingerprint databases of online real-time update. The technical problem, wherein online real-time update causes the prior art for being not easy to a large amount of audio fingerprint databases to solve. This method is for constructing online real-time update a large amount of audio fingerprint databases according to the present invention, comprising steps of the corresponding relationship between audio-frequency fingerprint, establishing has same keyword value and the key assignments; Establishing index list includes that each key value and audio-frequency fingerprint correspond to the key assignments, wherein pointer of each key assignments index instruction in the form of corresponding audio-frequency fingerprint; Continuously storage audio-frequency fingerprint has the record of identical key assignments. It is real-time to support to add and delete music fingerprint that this method and device make online service engine, not by search service, task of complicated sum being avoided to waste time is because of building offline database and the service of playing, ensure a large amount of audio fingerprint databases of the timeliness of data, and the requirement that can be updated in response to secondary data. ;The 2016 of copyright KIPO submissions
