NHK has been researching Super Hi-Vision (SHV) as a next-generation broadcasting system. SHV aims at an ultra-high definition television (UHDTV) system with a 7,680 × 4,320 resolution (8 K resolution), 120-Hz frame frequency, and wide-colour gamut, which we refer as `full-specification SHV', although its R&D was initiated with limited parameter values owing to the available technologies. In this paper, we discuss the equipment developed for a full-specification SHV system. Utilising CMOS image sensors for capturing 8 K images at 120 Hz and a prism designed for the wide gamut, we produced the world's first full-specification SHV camera system. A new signal interface for studio equipment was developed to transmit the full-specification SHV signal with a data-rate of approximately 144 Gbit/s using a single optical cable. In addition, we developed an 8 K/120 Hz liquid crystal display and 8 K/120 Hz wide-colour gamut laser projector. We used these pieces of equipment to produce full-specification SHV video content, and confirmed the improvements in the image quality of 8 K resolution, 120-Hz frame frequency, and wide-gamut colorimetry.
