| The ultimate broadcasting system will convey a heightened sensation of reality to the viewer. Viewers could feel as though they were actually at the broadcasting site, or that the object they are viewing is right in front of them. With such a system as our ultimate goal, research continues on the Super Hi-Vision system. This system boasts extremely high resolution video with 16 times the number of pixels of the current HDTV system and a 22.2 multichannel three-dimensional sound system. |
- Its video format uses 7,680×4,320 pixels (16 times the pixels in an HDTV), and a 60-Hz frame rate progressive scanning scheme, making it possible to present an unparalleled amount of information on a screen.
- It employs a 22.2 channel 3D loudspeaker arrangement to realize excellent sound field reproduction and a wide listening range.
- Broadcasting satellites in the 21-GHz band have potential as a delivery system for broadcasting of Super Hi-Vision to individual homes. we are studying special compensation technologies employing a phased array antenna system to solve radio attenuation problem caused by rain in 21-GHz band.
- We constructed an OB van system for carrying a compact ultrahigh-definition camera and hard disk recorder, and shot videos that are being presented at the 2005 World Exposition, Aichi*, Japan.

We are positioning the Super Hi-Vision system as a core medium for future audio video technologies, and conducting research and development in view of broad application possibilities. Special attention will be given to an introduction scenario for home receivers. Research and development in this area will progress with constructing a system for recording and transmission and a lightweight home display device with a low profile. From the aspect of human sciences, we will study the psychological and biological effects of large-screen, wide-view video and audio presentations.
* The World Exposition is being held in Aichi prefecture, Japan , until September 25, 2005. |
