Japanese - 33 million pixel TV Standard

January 22, 2008 | Chris Payatagool
ultrahighdef.jpgAmericans are still stumbling today to upgrade their ailing televisions to HD standards. Many do not realize that their friendly broadcast over the waves is about to change. As America pushes the Hi-Def deadline back, the Japanese are pushing forward with plans to drop their "Hi-Vision" standard pioneered by NHK, who is a Japanese broadcaster . The Hi-Vision technology was also used on the JAXA moon mission. The communications ministry is pouring 300 million yen into the NHK project to develop and launch a higher quality 33.2 million pixel broadcast standard by 2015. Due to the ailing USD, that is 2.735 million dollars.

The broadcast standard will be able to travel along 260 kilometers of fiber optic cable and carry 16 different wavelength signals. The total bandwidth they have achieved in tests is 24 gigabit. Back in 2003 and 2005 NHK demonstrated the "Super-Hi-Vision" technology. Back then, there were 16 HDTV recorders hacked together recording 18 minutes of footage. They took the resultant 3840 x 2048 image and "upscaled" it through pixel shifting to 7680 x 4320 pixels or 4000 scan lines. Three years later, the project is still advancing and has overcome many of the hurdles they once had.
