BBC Starts Broadcast in Ultra High Definition

The BBC and Japan's NHK teamed up this week to go Super Hi-Vision, which is also known as Ultra High Definition, and simply 4320p. This format is 16 times better than regular HDTV which 1080p. 

In terms of the cameras, back in 2003 when this experiment was announced, it took 16 separate HDTV cameras to produce the pilot video.  These days, there are three cameras, all developed by NHK, that can handle the video's 7680 x 4320 resolution, but for this broadcast, the NHK had to create a customized lens and a 103-inch plasma screen for viewers.

Of course, the other big issue is space. We're talking about terrabytes of storage for video. A 20 minute video requires 4 terrabytes of space. Sheesh!
