Japanese govt plans input on ultra high-definition TV


Nowadays, if you have a HDTV that can display 1080p video, you have the best picture quality that high-definition can offer to consumers right now. We have reported several times in the past about UHDV, or Ultra High-Definition Video, which later became known as Super Hi-Vision. For most of our readers, going by comments and feedback, it seems like a dream that won't be seen for a long time yet.

For those that don't know, UHDV or Super Hi-Vision consists of video at a resolution of a massive 7680x4320. Try to envision a 33-megapixel image, which is exactly what this resolution offers. It runs at 60 frames per second. It doesn't lack in the audio department either, offering 22.2CH audio (9 above ear level, 10 at ear level, 3 below ear level and 2 low frequency effects).

Now, the Japanese Government is set to begin a joint project with private companies to develop this next generation technology. The goal is to make this concept a broadcasting standard by 2015. Of course, there have been many technical problems like the development of a camera that can record it and equipment to transfer the 24Gbps uncompressed stream.

Some public testing with UHDV video required an array of 16 HDTV recorders to capture just 18 minutes of footage, about 3.5TB of space. The recorded footage was projected on a 4x7 meter screen for a public demonstration. Reports were that it gave an experience of actually "being there". People experienced nausea while watching the footage.
