Demonstration of 8K video at TNC16

June 16, 2016 at TNC16 Networking Conference, he largest and most prestigious European research networking conference, CESNET has demonstrated in collaboration with the colleagues from Polish PSNC centre the first live 8K video transmission using the PC platform. An interactive transmission connected the PSNC centre in Poznan with the TCN16 conference venue in Prague across the Géant network. The transmission was implemented using the UltraGrid SW developed by CESNET for very high quality video and audio transmissions. The transmissions of live video with 8K resolution introduce a number of technical challenges. Uncompressed video with 8K resolution (7680×4320) at 60 frames per second means a bitrate of almost 30 Gbps. Up to date gaming PCs are capable of processing such a bitrate. Moreover latest GPUs have enough performance to compress the 8K video at 60 frames per second in real time using the highly optimized GPUJPEG codec. The GPUJPEG codec, a part of the UltraGrid platform, is also developed by CESNET. The resulting bitrate of the transmitted 8K video is approximately 3.5 Gbps. Hence it is possible to implement such a demanding transmissions using commodity, academic networks and two high-performance gaming PCs.
