Abstract
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 head-mounted 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 high-quality 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.
