NHK Science & Technology Research Laboratories

NHK Science & Technology Research Laboratories (STRL) is to build a richer broadcasting culture from a research and development viewpoint, both as Japan's only research organization dedicated to broadcast technology, and as part of Japan's public broadcaster. NHK STRL is conducting a wide range of R&D, from basic research to practical applications: advanced program production technology, internet technology for broadcast services, 8K Super Hi-Vision, 3D television, universal service. We are using these technologies to enrich programming and are actively working on the international standardization, which is essential for implementation of new services.
