Patent ID: 7756595

Claim:
A live performance management device for controlling a plurality of live performance providing apparatus each operable to output a live performance signal, said device comprising: means for generating synchronization information and for supplying the synchronization information to only one of the live performance providing apparatus by way of a communication network; means for receiving a respective live performance signal and the synchronization information from each of the live performance providing apparatus by way of the communication network, wherein the synchronization information received at the receiving means from each of the live performance providing apparatus other than the one live performance providing apparatus is based on the synchronization information transmitted from the one live performance providing apparatus to a second live performance providing apparatus of the live performance providing apparatus other than the one live performance providing apparatus; synchronization correction means for performing a synchronization correction process on the live performance signal based on the synchronization information received from each of the live performance providing apparatus; and synthesizer means for synthesizing the live performance signals synchronization corrected through the synchronization correction means.
