AN EFFICIENTAUDIO-VIDEOSYNCHRONIZATIONMETHODOLOGY

Ina multimedia information system, different typesof digital media(suchasvideo, audio, etc.) arestored, transmitted, andpresented. During presentation time, the synchronization between audioandvideodatahastobe preserved inorder tooffer thebestperceptual quality. However,the timestamp-based synchronization methodology inMPEG/System layer suffers datapacket lossduring transmission, andtheresulted absence of synchronization will beunacceptable forusers. Inorder to addressthisissue, an information hidingbased synchronization methodology hasbeenproposed. Inthis methodology, audiodatais embeddedwithinthe corresponding videoframesbymeansofhighbitrate information hidingtechniques. At thereceiver, the embedded audio dataisextracted andplayed withthehost videoframes toachieve thesynchronization. Withthis approach, significant advantages havebeenobtained: (1)the communication channel foraudiodatatransmission is avoided; (2)thesynchronization between audio andvideo data isrobust topacket loss.
