8K-UHD Video Transmission Experiment
in Snow Festival 2019
• Video Transmission Experiment in Sapporo Snow Festival
• Since Feb. 2003
• Trying Different Technical Challenges every year
• Ex.) International Multicast-Multipath Transmission,
25Gbps real-time video encryption
• 49 organizations (companies / universities / institutions) including
broadcasting companies, and over 150 people joined the project this
year

What is 8K-UHD ?
• 8K UHDTV (Ultra High Definition TeleVision): 33million pixels 7680 pixels
3840
• 4K: 3840 x 2160 pixels (4 times as many pixels as HDTV) 1920
• 8K: 7680 x 4320 pixels (16 times as many pixels as HDTV) 1080 HDTV
• Proposed by NHK Science and Technology Research Laboratories 4320 2160 4K
• Defined and approved by ITU-R and SMPTE pixels
• There are several formats in uncompressed 8K. 8K
• In this experiment: 8K-DG(Dual Green) format.

8K-UHD Dual Green format
• 8K-UHD Dual Green is two Green
• Green elements are the high ratio for brightness, so big influence for human eyes
• Realizing video with resolution feeling like 8K while

8K Uncompressed Video IP Converter
• Video transmission device
(RTP over UDP/IP)
• IP network (10Gbps) transmits
uncompressed video up to 4K 30P
• Multiple video streams can be transferred
simultaneously
• Tandem operation provides up to 8K
uncompressed video transmission
• The QG70 allows the synchronization of
multi channel signals and multi devices for
transmitting 4K/8K images
• Using four QG70, these operation can
provide
upcompressed 8K DG 60P system.
