| Research Abstract |
The next contents of recently prevailing 3D contents are immersive contents. The users immerse themselves to the content world and enjoy it. There is a problem for them that the playback interruption time is very long under conventional broadcasting systems since the data size is very big. Hence, in this research, we realized broadcasting systems for immersive contents with no interruptions by exploiting stored playback, in that the clients receive the data beforehand and play them later. We proposed broadcasting schemes that divide immersive contents into the model data and the action data targeting various broadcasting systems such as electric wave broadcasting or node-relay broadcasting. Action data give actions to model data. Our evaluations show that our proposed schemes can avoid interruptions.
