Future challenges of UHDTV technology and expectations for RD in photonics

摘要

For the 2020 Tokyo Olympics and Paralympics, NHK is preparing 8K devices for 8K regular broadcasting.However, the equipment is in the early stages of development; therefore, it is necessary to continue improvingtheir performance and operability. Particularly, the sizes of the cameras and lenses are larger than those forHDTV. Furthermore, handling uncompressed data is challenging because of the sheer size of the data. In thispresentation, we introduce the current 8K UHDTV technologies that are closely related to photonics technologyand the challenges for its development. Moreover, we describe our expectations for the research and developmentin the eld of photonics.
