Demonstration of 8K video at TNC16June 2016
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. You can learn more at CESNET website (post is available in Czech only).

CESNET and the Laboratory of Advanced Networking Technologies (SITOLA) are happy to announce a new stable release of the UltraGrid software for low-latency and high-quality video transmissions over IP networks. The current stable release is versioned 1.5 and is available for download for all supported platforms at http://www.ultragrid.cz/.
Another story featuring UltraGrid has been published by In the field blog. The authors go back to the net:art near in the distance production performed Brucknerhaus Linz in June 2017. The near in the distance 3 production connected multiple locations across Europe including Linz, Barcelona, Prague, and Rome. UltraGrid and LOLA were deployed and integrated into a single audio-visual performance. Read the whole story In The Field Stories blog.
