At the GSCA Film Expo 2025 held in Los Angeles, NHK presented video content captured with an 8K square sensor camera. The 8K square sensor camera enables the capture of high-resolution images with an ultra-wide field of view.

STRL is developing a sign language translation AI specialized in breaking news articles, along with control technologies for sign language location and mouthing to convey the content more accurately.

Just one week to go until STRL Open House 2025. We can't wait to welcome you—see you there!. When: May 29, Thu. – Jun 1, Sun. Where: NHK STRL (Setagaya, Tokyo).

STRL is conducting R&D on a cryptographic technology known as the proxy re-encryption method. By using this method, data can be stored in a single storage location, which is expected to enhance the efficient use of storage capacity and simplify management.

Members of STRL participated in the EBU Production Technology Seminar 2025, which was held in Geneva from Jan. 28 to 30. Director Kanda delivered a lecture, introducing the world envisioned for 2030-2040 outlined in Future Vision 2030–2040 (2024 Version).

STRL Open House 2025 Website is now OPEN!.Please take a look at the overview of our exhibits and be sure to watch our "Future Vision" concept video.

As an initial study for 360-degree video services, a subjective quality assessment was conducted to evaluate the QoE of a 360-degree video with 8K pixels, compressed and encoded using the HEVC method, when displayed on different devices.

A prototype of a high-quality 360-degree.camera and recording equipment has been developed, capable of capturing.spherical 360-degree images at a 30K pixel resolution by integrating multiple.camera units.

A method has been developed to train speech recognition models on overlapping voices without the need for auxiliary information. It is possible to train highly accurate models using real conversational audio.

STRL has developed the world’s first real-time VVC multi-layer encoder that enables video content layering. We are conducting research to realize sub-content broadcasting that provide sign-language, captions, etc, to offer a new experience to viewers.

STRL Open House 2025 is planned to be held from May 29 (Thu) to June 1 (Sun) at the NHK STRL on the theme of “Expanding, connecting, and deepening your experience!”.An overview of the exhibits, etc., will be rolled out gradually in future releases.

We've updated our STRL overview video!.Please take a look at our history and initiatives toward the future.

STRL has been conducting research on wireless transmission technology using millimeter-wave in the 42-GHz band, which enables large-capacity transmission for use in the production of immersive content such as 360-degree video.

STRL is conducting research on technologies for producing immersive audio content that supports #6DoF experiences, enabling users to immerse themselves in content and move freely within it.

To achieve an imaging system acquiring high-definition 3D information, research is underway on incoherent digital holography (IDH) that can capture holograms under natural light such as sunlight.

NHK showcased recent R&D advances at IBC2024, held from September 13-16. NHK received comments from the visitors sharing the view on the R&D direction, and opinions were exchanged with them, which will lead to international collaboration.

We have been conducting research and development to realize "Future Vision 2030-2040" published in 2021. Future Vision has now been revised as the 2024 version, taking into account the latest changes in the media environment and technological trends.

STRL has developed the world's first thin, bendable silicon image sensor with a thickness of 0.01 mm and has succeeded in capturing images with significantly reduced horizontal blurring by operating the sensor in a curved configuration. #ImageSensor.

STRL is engaged in research to systematize the diverse content produced and published on the Internet by NHK, as well as related knowledge, from a learning perspective using Web technologies, to make it easier to utilize in educational settings.

With the spread of social media and generative AI, the world is being flooded with an unprecedented amount of information and content. In this context, STRL has begun research aimed at contributing to the realization of informational health.
