In-Depth Information
Imaging devices with 33 million pixels were not available when the cameras and
displays were developed. Another important point is that current display devices
are projectors, not direct-view displays. Thus, our next research target is the devel-
opment of a full-resolution camera and a direct-view display. We will develop a
full-resolution camera with three 33-million-pixel image sensors. We expect that
display manufactures will develop a flat-screen display with the full pixel count. By
developing such cameras and direct-view displays, we can provide people with
their first experience of seeing SHV images with full resolution in a home viewing
environment. We believe this advance will be instrumental for determining the sig-
nal parameters of future broadcasting. Besides developing the cameras and dis-
plays, we are developing compression techniques. These systems and technologies
can be used for various events, such as cooperative museum exhibitions, live relay
of sports events on a global scale, and public viewing of SHV programs.
NHK will continue its tireless research and development efforts in accordance
with the roadmap aiming to launch SHV broadcasting in 2020 - 2025.
