Media/playback device synchronization for the 4D broadcasting service system

In these days, various 4D media service system which can give users a lot of special effects (eg., wind, heat, light, vibration, scent effect, ect.) according to the contents has been developed with the increment of 3D media consumptions. Also, standardizations for presenting events in the virtual world to the real world are continuously progressed in the MPEG forum, and companies have developed systems to play media efficiently in the field of game, entertainment, education. These 4D systems are also adapted to the 4D broadcasting services. The 4D broadcasting service systems can transfer captured image from camera with SI(Sensory Information) on the spot to the home server of users. Therefore, there needs researches of the method for acquiring, inserting, time synchronizing, and transferring SI with captured 3D contents. To do this, in this paper, we explained the system architecture of the 4D broadcasting service system, acquiring time methods from an aggregator, time synchronization method between 3D contents and SI.
