DEVICE AND METHOD FOR SYNCHRONIZING MULTI-CHANNEL EXPANSION DATA WITH AN AUDIO SIGNAL AND FOR PROCESSING SAID AUDIO SIGNAL |
摘要 |
For synchronizing multichannel extension data with an audio signal, wherein the audio signal includes block division information and the multichannel extension data include reference audio signal fingerprint information, the block division information in the audio signal is detected by means of a block detector. Thereupon, block division of the audio signal is performed by a fingerprint calculator according to the block division information in order to obtain a sequence of test audio signal fingerprints. In addition to that, a sequence of reference audio signal fingerprints is extracted from the reference audio signal fingerprint information of the multichannel extension data. Both sequences of fingerprints are correlated in order to obtain a correlation result, by which a compensator is controlled in order to reduce or eliminate a time offset between the multichannel extension data and the audio signal. |
