Multiple devices synchronization and control architecture for orchestral media service system

Future digital home is changing into actual feeling/intelligence ubiquitous home, and the future media will include not only audio, video, text but also synchronizing information, control information to be orchestral media with user peripheral devices. To play this orchestral media, there needs efficient media/device synchronization method and multiple devices control technology. Therefore, we will explain active device and passive device synchronization, media/device synchronization, and multiple devices control methods for orchestral media.
