After decennia of developing leading-edge 2D video compression technologies, the Moving Picture Expert Group (MPEG) is currently working on the new era of coding for immersive applications, referred to as MPEG-I, where "I" refers to the "Immersive" aspects. It ranges from 360° video with head-mounted displays to free navigation in 3D space with headmounted and 3D light field displays. Two families of coding approaches, covering typical industrial workflows, are currently considered for standardization-MultiView + Depth (MVD) Video Coding and Point Cloud Coding-both supporting highquality rendering at bitrates of up to a couple of hundreds of megabits per second. This paper provides a technical/historical overview of the acquisition, coding, and rendering technologies considered in the MPEG-I standardization activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
