Keiichi Kubota, director-general of the Japan Broadcasting Corporation“s (NHK) Science & Technical Research Laboratories, predicted this morning at a demonstration of Super Hi-Vision (SHV) that the new television technology, carrying 32 times more information than 1080i HDTV, could reach homes in 10 years.
The demonstration featured a live feed from London carried over fiber-optic cable as well as one from a server in Turin, Italy, sent by satellite. The fiber feed used a data rate of 640 million bits per second (Mbps). The satellite feed, however, used just 140 Mbps, carried on two standard satellite transponders. It could be received by a dish only three feet in diameter.
Asked about a previous date of 2025, Kubota said it had been chosen as the centennial of broadcasting in Japan. But advanced research and international cooperation (today“s demonstration involved British and Italian broadcasters as well as NHK) now suggests that all standardization necessary for home reception of SHV could be completed in just ten years.
Today“s 1080i HDTV has 1920 x 1080 pixels at 30 frames per second. SHV has 7680 x 4320 pixels at 60 frames per second. During the live feed from London, the camera panned from the top of City Hall to the other side of the Thames River with extraordinary clarity.
