  1. IP Networks in the TV Studio Recent work by BBC R&D Stuart Grace April 2016

  2. Part One: The IP Studio Project at BBC R&D

  3. n T Current TV Studio Technology: Video • SDI (serial digital interface) for raw video feeds Coax cables with BNC connectors • • Synchronous, circuit switched Blanking intervals for • compatibility with CRT displays

  4. Current TV Studio Technology: Other Systems • Digital Audio (AES3 and AES10) Timing and • synchronisation • Talkback between locations • Tally lights Teleprompter • …all with separate cables

  5. Manual Patching in an OB Van

  6. Current Studio IP-based Studio Expensive specialist hardware Commodity hardware • • • Multiple cabling systems • Single multipurpose network Formats fixed in hardware Software defined formats • • • New production techniques • New forms of content

  7. Image Composition at the Studio Studio Home Combined image Vision Mixer

  8. Image Composition at the Display Studio Home IP streams www.bbc.co.uk/rd Search for “forecaster”

  9. SMPTE 2022-6: SDI video data over UDP

  10. Society of Motion Picture & T elevision Engineers European Broadcasting Union

  11. Recommended Protocols RFC 768 – User Datagram Protocol RFC 3550 – RTP: A Transport Protocol for Real-Time Applications RFC 4175 – RTP Payload Format for Uncompressed Video RFC 3190 – RTP Payload Format for 12-bit DAT Audio and 20- and 24-bit Linear Sampled Audio RFC 4566 – SDP: Session Description Protocol PTP: Precision Time Protocol IEEE 1588-2008 – Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

  12. Registration & Discovery Replication Standard open APIs

  13. Part Two: Streaming UHD Video – Uncompressed

  14. Uncompressed Studio Video Data format: 10-bit YCbCr 4:2:2  20 bits per pixel HD (high definition): 41.5 Mbits per frame 1080 2M pixels 25 frames / sec  1.04 Gbit/s 1920

  15. Uncompressed Studio Video Data format: 10-bit YCbCr 4:2:2  20 bits per pixel HD (high definition): 41.5 Mbits per frame 1080 2M pixels 25 frames / sec  1.04 Gbit/s 1920 UHD-1 (ultra high definition, 4K): 166 Mbits per frame 100 frames / sec  8M pixels 2160 16.6 Gbit/s 3840

  16. BBC News Gallery

  17. UHD-2 (Super Hi-Vision, 8K): 33M pixels 4320 7680 664 Mbits per frame 120 frames / sec  80 Gbit/s

  18. UHD Trial at the 2014 Commonwealth Games, Glasgow UHD-1 @ 50 frames / sec  8.3 Gbit/s

  19. Linux Network Stack

  20. Netmap with Standard NIC Driver

  21. Netmap with Optimised NIC Driver

  22. NIC Hardware Offloads

  23. NIC Hardware Offloads

  24. NIC Hardware Offloads

  25. Bursts of Traffic

  26. Bursts of Traffic Flow 1 Flow 2

  27. Bursts of Traffic Flow 1 Flow 2 Combined Flows

  28. Packet Pacing Tx rate limited to 3.5 Gbit/s in the NIC

  29. Packet Pacing Tx rate limited to 3.5 Gbit/s in the NIC Flow 1 Flow 2 Combined Flows

  30. Limitations • UDP  TCP  • Security – app sees all network traffic o Use separate interface for media streaming • Monolithic – app builds all headers from L2 upwards

  31. Limitations • UDP  TCP  • Security – app sees all network traffic o Use separate interface for media streaming • Monolithic – app builds all headers from L2 upwards But we get 75x increase in network I/O performance using COTS hardware

  32. CPU Load of RTP Sender Sending UHD-1 @ 50Hz Transmitting 8.6 Gbit/s with no packet loss Only one CPU core is busy

  33. Thank you www.bbc.co.uk/rd Stuart.Grace@bbc.co.uk @BBCRD
