The document introduces MPEG-V, a standard for interfacing with virtual worlds. MPEG-V includes four parts that define the system architecture and representations for information exchange between virtual worlds and between virtual and real worlds. Part 3, on sensory information, defines a language called SEDL to annotate multimedia content with sensory effects metadata to control sensory devices and enhance the user experience. The presentation provides an overview of MPEG-V and its goals of achieving interoperability and a better user experience through sensory stimulation related to multimedia content.
