NHK Science & Technology Research Laboratories

The role of 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 media organization NHK. NHK STRL conducts a wide range of both basic and applied research in broadcasting technology to fulfill this role. NHK STRL has led to creating new broadcast media, including satellite broadcasting, HDTV, and 8K, and has contributed to advancing program production technologies. We continue such research today, anticipating challenges the future will bring.
