1. Multi-channel streaming for medical and multimedia industry application TNC2011 Prague, 17 May 2011 Jiří Halák 1, Milan Šárek 1, Sven Ubik 1, Petr Žejdl 1 Pavel Pečiva 2, Jan Schraml 2 1 CESNET, 2 MNUL

2. CESNET is a National Research and Educational Network (NREN) in Czech Republic established in 1996 10 Gb/s DWDM hybrid network connections to Géant, GLIF national and EU research projects www.ces.net CESNET

3. Ultra high-definition video is used in various scientific and industrial applications Low-latency sharing of such content can enable remote collaboration of distributed teams or enhance education Leveraging our experience in high-speed FPGA supported network traffic monitoring & processing Motivation

4. Uncompressed transfer of 4K (4096x2048) and scalable to higher resolutions Low latency (for interactive work) Working across Internet infrastructure (routers, switches) Lightweight and easy to deploy Requirements

5. MVTP-4K Input: 8x HD-SDIOutput: 8x HD-SDI Network – 10 Gigabit Ethernet Modular Video Transfer Platform uncompressed transfer adds less than 1 ms to networking delay full-duplex single- or dual-link embedded audio

6. Hardware structure

7. 8x HD-SDI full-duplex transmission over packet network MVTP-4K

14. Two modes for each HD-SDI separately - full frame: approx. 1.5 Gb/s per channel - visible frame only: 0.8-1.2 Gb/s depending on format Allows to pack 8x HD/2K with audio to 10GE (up to 25 fps, higher fps for 7 channels) Receiver HD-SDI outputs are synchronized No external clock source needed, receiver adapts to incoming data rate automatically Features

15. Low-latency 4K transmissions for: real-time remote post-production of multimedia content streaming from events to remote auditoriums Stereoscopic and multi-view transmissions for: e-learning in medicine and other fields collaboration on scientific models (CAVE) Applications

16. Cinegrid 2009 - In cooperation with CINEPOST - Remote real time uncompressed 4K color grading - 4K content and colorist in Prague (Barrandov studios) - 4K projector and DoP in San Diego - 5 Gb/s sustained bit rate

17. Uncompressed 4K x 2K content edited in Prague and sent in real-time to San Diego (>10000 km) Cinegrid 2009 Director of photography Parallel videoconference

18. Cinegrid 2010 In cooperaton with UPP Remote 3D 2K post-production 2.5 Gb/s sustained bitrate

20. Robotic surgeries are laparoscopic operations with the surgeon using 3D vision and console to manipulate instruments They generally enable minimally invasive operations with less bleeding, lower stress for the patient and less fatique for the surgeon Medical universities and conferences can use real-time low-latency transmissions of 3D vision from robotic surgeries for educational purposes Robotic surgeries

21. Intuitive Surgical company in more than 800 hospitals around the world cost about $1.3 million da Vinci Surgical System

22. 3D HD transmission to conference daVinci Surgical System in Masaryk Hospital in Ústí nad Labem urological operation lead by MUDr. Jan Schraml, head of department audience at 5th International congress of mini-invasive and robotic surgery, Brno, Czech Republic, October 2010

25. 3D HD transmission CZ to Japan Robotic surgery in Masaryk hospital in Ústí nad Labem, Czech republic Approx. 11000 miles / 17600 km 10 Gb/s path

26. 3D HD robotic surgery to Tsukuba, Japan (Nov. 2010) 150 ms network delay + 1 ms sender & receiver delay (negligible) Parallel full HD videoconference for commentary and questions

27. 3D HD robotic surgery to APAN meeting, Hong Kong (Feb. 2011) Robotic surgery in Masaryk hospital in Ústí nad Labem, Czech republic 150 ms network delay + 1 ms sender & receiver delay Parallel full HD videoconference for commentary and questions Approx. 11000 miles / 17600 km 10 Gb/s path
