Japanese public broadcaster NHK says that next week (May 28-31) during NHK’s Science & Technology Research Labs ‘open day’ in Tokyo that it will showcase its latest developments for 8K ‘Super Hi-Vision’ transmission.

NHK will transmit 8K material to the ‘Open Day’ using its BSAT-1 broadcast satellite on Channel 17. Highlights for the public will be the compression system used to reduce the huge 72 Gb/s image files to 85 Mb/s for broadcast.

NHK Labs says that it are using HEVC video encoding, and the MMT (MPEG Media Transport) standard for use in multiple transmission channels and MPEG-4 AAC for its 22.2 channel sound capability.

“By incorporating these technical elements for the realization of 8K broadcasting, this public demonstration will enable visitors to gain the advance experience of next year’s test 8K broadcasts,” said a NHK statement.

NHK will be showing an 8K recording (33-megapixels) in ultra-HDTV from NHK’s Symphony Orchestra of Tchaikovsky’s Symphony No. 6 (the Pathetique) conducted by Herbert Blomstedt, and captured last September.
