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.
