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

• 4K: 3840 x 2160 pixels (4 times as many pixels as HDTV)

• 8K: 7680 x 4320 pixels (16 times as many pixels as HDTV)

• Proposed by NHK Science and Technology Research Laboratories

• Defined and approved by ITU-R and SMPTE

• There are several formats in uncompressed 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 suppressing information

8K Uncompressed Video IP Converter

PFU QG70(8K=4K * 4) * 2set

• 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 provideupcompressed 8K DG 60P system.
