  1. Grass Valley SET Expo 2018 Case Studies

  2. Studio Application North American Network

  3. The Challenge • Design a COTS based infrastructure solution for a Top 10 US market station. • Customers core requirements: • COTS based infrastructure - Cisco • Standards based –TR04 with ability to upgrade to ST-2110 • Mixed Reference Environment – Black Burst and PTP • Signal agnostic – HD 1080i 60, with ability to transport UHD • Future-ready - HDR (High Dynamic Range) and 1080p • Simplified wiring– multi-mode and single-mode fiber • TOR and EOR Design

  4. The Challenge • Studio technical requirements: • 3 Studios • As Much IP at the Edge as Possible • Traditional SDI switcher • Very large multi-viewer requirement • Master Control and Live Production • Extensive IP/SDI Connectivity with Video & Audio Processing • Remote Production Requirement • Large video Ingest and Playout requirement

  5. The Challenge • Studio technical requirements: • Distributed IP infrastructure • Spans multiple floors • Multiple sites around city • Uncompressed and compressed feeds • Multiple Codecs • J2k • H.264 • MPEG 2

  6. The Challenge Key that the users don’t know or care about the technology

  7. How did we do it? • Cisco Core • DCNM • Installed on Cisco UCS platform • Multiple VM’s for redundancy • Multi-Spine • Cisco 9236C • Multi-Leaf • Cisco 93180LC—EX • 2022-7 X-Y Design • Ties into broadcast LAN

  8. How did we do it? • Grass Valley Gear • IPG-3901 2x10G SDI-IP Gateways • Small failure block was key to high availability solution design • GV Node 12x40G used for vertically accurate IP switches • KMX-4901 IP Multi-viewers • LDX-86N IP Studio Cameras • GV Convergent SDN Control and Flow Management • iControl for unified facility monitoring and configuration

  9. Network Topology

  10. High Level Overview BLAN is Broadcast LAN • Management of all broadcast devices Media LAN is all TR-04 Media Transport

  11. IP Core X and Y Spines 11 + 11 Leaves Approx 150 IPG’s 10 GV Cameras 6 GV Nodes w KMX

  12. Remote Facility Requirements • Redundant 100G media trunks to remote facility • Remote facility uses third party switch • Interop was not an issue • GV Convergent controlling flows and managing bandwidth between the sites • Redundant 10G trunks to broadcast LAN for control and monitoring

  13. Modular IP I/O (2 x 10GbE SFP+)

  14. GV Convergent • GV Convergent was used as SDN interface to DCNM • Used to configure all IP devices and end-points • High level topology view • Key to give quick and simple view of entire solution • With DCNM integration we simplified system diagnostics • Path view of media flows • Real-time data on system bandwidth • Security was key principle • Default deny ACL • Only flows that have been managed by GVC are allowed

  15. Topology View

  16. Path View Select destination to examine Source Destination Shows route through both X and Y networks

  17. PTP • Pick your Grand Master Clocks carefully • This GM was fixed to 1G SFP, Media Network switches only support 10G+ SFPs • Only one NIC on each GM • Required the use of extra switches to distributed PTP • PTP was distributed to Media Network, Broadcast LAN, and station operations network • On hindsight, PTP was built overly complicated • Extra PTP distribution switches added a lot to complexity

  18. PTP High Level Broadcast LAN PTP Distribution switches X-Y Media LAN

  19. PTP Distribution LAN

  20. PTP Media Network

  21. PTP into Broadcast LAN

  22. Audio Interop was initially an issue • GV gear was using Level C • 125 packet timing • 16 channel trunks • Audio Console only supported Level A • 1ms packet timing • 8 channel trunks • Intercom was using Level C

  23. SMPTE ST 2110-30: Audio SMPTE ST 2110 – 30 (uncompressed audio – RFC 3190) Specifies the real-time, RTP-based transport of PCM digital audio streams over IP networks by reference to AES67. An SDP-based signalling method is defined for metadata necessary to receive and interpret the stream Uncompressed linear PCM audio only Relatively flexible 48kHz sampling 16 and 24-Bit depth Variable packet timing è 125us to 1ms Channel count based on packet timing è 8 channels @ 1ms vs 64 channels @ 125us Low bandwidth consumption è 8 channels x 24 bits x 48,000 samples x 1.5 (RTP) = 9.7Mbits/sec Published

  24. SMPTE ST 2110-30: Audio Levels SMPTE ST 2110 – 30 (Uncompressed Audio – RFC 3190)
