As a broadcaster in Japan, QVC had the opportunity to begin broadcasting UHD content in line with the Japanese broadcast deployment schedule for UHD. QVC selected Diversified to serve as technology partner and system integrator and Imagine Communications as lead technology supplier to provide a solution to meet their unusual 24×7 live production requirements, in UHD, with full HDR support. This talk describes the scale of the system, the technical approach, the technologies involved, and some lessons learned in the project.

ST 2110 UHD HDR facility at QVC Japan John Mailhot, CTO Networking & Infrastructure, Imagine Communications Jon Panneman , SVP Emerging Technologies, Diversified What makes this project interesting? • Full - Chain Requirements • Multiple Live Studios with 20+ cameras • Dual Production Control Rooms (fully mirrored) • Dual Network Master Control (fully mirrored) • 24 MV canvases (re - entrant) with 216 unique pips • Multiple regional variations downstream • 24x7 full production requirements • All in UHD and HDR Why IP ? Which IP? • IP Networks can scale to the required size • SMPTE 2110, fully uncompressed, lowest latency • ST 2110 -20 • UHD (Single -Stream) video streams • HD video streams • ST 2110 -30 audio • Streams sized to reflect real mixes • ST 2110 -40 ANC data General Architecture • Dual IP Cores (Arista 7504R) • 100G "universal" ports • Devices with high port utilization are direct - to - core • 7 Leaf switches (per core) are used to aggregate monitors, audio, and other low - utilization signals • PTP Boundary Clock in the Core • Dual PTP generators (Evertz) via leafs IP Stream Switching • UHD signals are single - stream in this network • 10.1 Gbits /sec per UHD stream (2160p59) • Devices in the air - chain support make - before - break switching model • Utility devices (test, monitoring) may not Redundancy Redundancy • This is a 24x7x365 live multi - studio production • Feeding live master control • Feeding regional variations with complex graphics • There is redundant equipment including full production - control - room redundancy • 2022 - 7 hitless redundancy of all signals provides redundancy and maintainability of the core IP plant Principle Equipment • Arista 7504R (and other smaller) IP infrastructure • Imagine Selenio Network Processor • SDI/IP gateways for UHD and HD • Up / Down Conversion including HDR conversion • Grass Valley K - frame UHD switchers • Imagine EPIC - MV Multiviewers • Harmonic UHD servers • Ikegami UHD Cameras • Evertz UHD Downstream Keyers More Equipment • Ross "newt" back - of - monitor conversion • Evertz PTP generators • DirectOut Montone42 MADI/IP • Tektronix Prism test equipment • And some others By the Numbers • 200 unique UHD signals in the network • 200 unique HD signals (plus HD versions of UHD) • 710 unique audio streams (multi - channel streams) • 175 unique ANC data streams • 1485 (primary) multicast groups (plus 2x secondary) • 200 by 200 (UHD video) routing system • 400 by 200 (HD video) routing system • 710 by 1600 (audio stream) routing system • 175 by 500 (ANC Data) routing system • Adding 75 more UHD src & dest soon What did we learn ? • Japan is a wonderful country with friendly people and great food. • And trains that work perfectly What did we learn technically? • PTP – the backbone of everything. Get it right, check it often, have a monitoring approach • There will be lots of multicast addresses – have a plan and follow it and keep it accurate • Test equipment is not optional – at the video layer and at the IP layer Questions?
