Ultra-high-definition television in the context of "NHK"

DaVinci Resolve is a proprietary application for non-linear video editing, color correction, color grading, visual effects, and audio post-production. It is developed by the Australian company Blackmagic Design for macOS, Windows, iPadOS and Linux. The software was originally created by the American company da Vinci Systems and released as da Vinci Resolve. In 2009, da Vinci Systems was acquired by Blackmagic Design, which has since continued the software's development.

DaVinci Resolve is available in two editions: a free version, and a paid version known as DaVinci Resolve Studio. The Studio edition includes support for resolutions beyond 4K (up to 32K) and frame rates up to 120 frames per second, as well as 10-bit video processing, multiple GPU acceleration, stereoscopic 3D, HDR grading, collaborative workflows, additional plug-ins and AI-driven features.

Digital terrestrial television (DTT, DTV, or DTTV) is a broadcast technology that transmits television signals digitally over the air, replacing analog transmission methods. It has become the primary form of free-to-air broadcasting in many countries, offering improved picture quality and the capacity to carry multiple channels within a single frequency. Reception typically requires a television antenna and a compatible receiver, such as a HD/UHD TV or set-top box.

The conversion from analog to digital broadcasting, known as the digital transition or analog switch-off (ASO), began with experimental transmissions in the 1990s. By the mid-2000s, many governments had established timelines for phasing out analog signals, with deadlines for the changeover, often including subsidies for equipment upgrades and limited exemptions for remote areas. Regional technical standards differ widely. North America and South Korea developed ATSC 1 and ATSC 3.0, while Europe and most of Africa and Oceania primarily use DVB-T and DVB-T2. Japan and much of Central and South America adopted ISDB-T and ISDB-Tb, and China operates the DTMB standard. Some of these standards also support mobile reception and interactive features. By late 2024, the International Telecommunication Union and DVB/EBU reported that more than 160 countries had completed their DTV transition, while some states were still in various transition phases.
