End-to-end framework for 4-D broadcasting based on MPEG-V standard

Advances in media technologies brought so-called 4-D movies to your neighbour. The 4-D movies represent movies (preferably in 3-D) with additional sensory effects such as motion chairs and wind effects. We present an end-to-end framework to provide sensory effects for home theaters based on MPEG-V standard. The key technologies of the 4-D broadcasting framework, required to provide sensory effect through home theaters consist of creating sensory effects synchronized with audiovisual contents, delivering the sensory effects with content to home theater devices, recognizing home devices for rendering sensory effects, and rendering contents through home theater system with connected sensory devices in a synchronized way. This paper proposes end-to-end technology required, in addition to the conventional broadcasting framework, based on international standard of MPEG-V, specifically Part 2 to describe capabilities of the home sensory devices, Part 3 to provide contents with sensory effects, and Part 5 to command the sensory devices among other parts of MPEG-V standard.

► It provides a framework for 4-D broadcast service based on international standards. ► 4-D broadcast is defined in terms of AV contents with accompanying sensory effects. ► Standards to carry the sensory effect metadata over broadcast network are reviewed. ► A standard based method to recognize the sensory effect devices is proposed.
