Guaranteeing interoperability between devices and applications is the core business of standards organizations. Since its first JPEG standard in 1992, the JPEG committee has published several image coding standards that were successful in a plethora of imaging markets. Recently, these markets have become subject to potentially disruptive innovations due to the rise of new imaging modalities such as light fields, point clouds and holography. These so-called plenoptic modalities hold the promise that they facilitate a more efficient and complete representation of a 3D scene when
compared to classic 2D modalities. However, due to the heterogeneity of plenoptic products that will hit the market, serious interoperability concerns arise at the horizon. In this paper, we particularly focus on the holographic modality and outline how the JPEG committee addresses these tremendous challenges. We discuss main use cases and a preliminary list of requirements. In addition, based on the discussion of real-valued and complex data representations, we elaborate on potential coding technologies that range from approaches that utilize classical 2D coding echnologies to holographic content-aware coding solutions. Finally, the paper addresses the problema of visual quality assessment of holographic data covering both visual quality metrics aspects as subjective assessment ethodologies.
