Movie Theme Wallpaper Biography
Since this format is highly experimental, NHK researchers had to build their own prototype from scratch. In the system demonstrated in September 2003, they used an array of 16 HDTV recorders to capture the 30-minute-long test footage.
The camera itself was built with four 2.5 inch (64 mm) CCDs, each with a resolution of only 3840 × 2048. Using two CCDs for green and one each for red and blue, they then used a spatial pixel offset method.[4] to bring it to 7680 × 4320.[5]
The system was demonstrated at Expo 2005, Aichi, Japan, the NAB 2006 and NAB 2007 conferences, Las Vegas, at IBC 2006 and IBC 2008,[6] Amsterdam, Netherlands, and CES 2009. A review of the NAB 2006 demo was published in a Broadcast Engineering e-newsletter.[7] In November 2005, NHK demonstrated a live relay of a UHDTV program over a distance of 260 km by a fibre optic network. Using dense wavelength division multiplex (DWDM), 24 Gbit/s speed was achieved with a total of 16 different wavelength signals.
On December 31, 2006, NHK demonstrated a live relay of their annual KĊhaku Uta Gassen over IP from Tokyo to a 450 inch (11.4 m) screen in Osaka. Utilizing a codec developed by NHK, the video was compressed from 24 Gbit/s to 180–600 Mbit/s and the audio was compressed from 28 Mbit/s to 7–28 Mbit/s.[8] Uncompressed, a 20 minute broadcast would require roughly 4 TB of storage.
In another indoor demonstration at the NHK Open House, the UHDTV signal was compressed to a 250 Mbit/s MPEG2 stream. This was later input to a 300 MHz wide band modulator and broadcast using a 500 MHz QPSK modulation. This "on the air" transmission had a very limited range (less than 2 metres), but shows the feasibility of a satellite transmission in the 36,000 km orbit.
