Study on new media synchronous control system for outdoor complex surface projection

With the rapid development of new media technologies, outdoor live performances integrated with projection, LED screen, spotlights, fountain, multichannel music systems and other technologies become more and more common. To solve the problem of lip sync delay and other delay among different systems, a novel synchronous control technique for new media system was proposed. A data buffer was added to solve the synchronous control problem in the same system with changing playing speed and skipping frame or repeating frames. Timestamp synchronous control method was improved with feedback mechanism. The size of time domain data buffer can be changed automatically for the realization of a variety of new media technologies synchronous control.
