How does the HEMC recognise the content in a D-Box system

Movies are encoded frame by frame to perfectly match the on-screen action. D-BOX motion artists add another dimension to audio and video by integrating motion. They program every single movement in a movie as a separate track. This motion track is then added to audio and video. They create layers of vibrations and motion effects based on the action, the characters and music to enhance and support the storytelling. Whenever the viewer is selecting a movie for which a Motion Code was created, automatically the HEMC will recognise the signal and will push the motion into the chairs perfectly in-synch with the on-screen action.
