4 NHK Corporate Plan Vision Statement 1 : Looking forward to 2020, the year of the Tokyo Olympic and Paralympic Games, NHK (Nippon Hoso Kyokai, also known as Japan Broadcasting Corporation) endeavors to provide broadcasting and services of the highest standards, utilizing leading edge technologies. NHK Corporate Plan Major Objectives 1 : Creating Broadcasting and Services that open up new possibilities Focus on new services utilizing 8K, the internet, and other technologies to provide new audience value Implement the total reach concept, enabling content delivery through a wider range of media Fulfill our role as a technical pioneer Enhance creativity and strengthen content production capabilities by operational structure reforms 1: NHK s corporate plan for Please reference

5 Technology Selection Infrastructure Replacement with IP Switching Infrastructure Replacing the central switching and distribution from coax to 10GbE fiber with multiple bi-directional video streams per link Concept known as Video IP Routing Switcher Media Links has 8 years past operational experience in Fuji TV as a model MD Max (2008) Fuji TV - 10G Ethernet 160 ports HD Media Global Links.

6 Technology Selection Where are the boundaries? For the contribution/primary distribution network; SMPTE2022-6/SMPTE For In-Studio application, SMPTE2110 in definition now, however ASPEN/NMI, are the present solutions (during design phase 2014) For remote production, the solution will be affected by the camera vendor s or encoding strategy Central Switching must be hybrid /IP to enable workflow to migrate to IP in other areas Network Remote Production Central Video Switching Facility ( 回線センター ) : SMPTE2022 Broadcasting Station Boundary Post Production Master Studio : In-Studio 2016 Media Global Links.

7 Technology Selection Decisions SMPTE2022-6/SMPTE are popular wide area formats Central Video Switching Facility ( 回線センター ) SMPTE2110 was still in development ASPEN/NMI are proprietary Stick to for core infrastructure with adapters Edge Adapters Edge Adapters Redundant Core Infrastructure Edge Adapters Edge Adapters Redundant Core Infrastructure 2016 Media Global Links.

8 Technology Selection JPEG2000 video monitoring system Each ingress is replicated in for main content distribution and JPEG2000 (TR-01) for monitoring 1GbE Networking can be used for monitor feeds Small, low power JPEG2000 decoder to HDMI is used at monitor locations HDMI GbE Video-In J2K- Enc Video-Out IP-GW IP-VR L2 SW IP Decoder 2016 Media Global Links.

9 Important Project Requirements

10 Important Project Requirements Edge Capacity and QoS Configuration Two Configurations: 4 x Tx (+ 4 J2K monitoring streams) + 4 Rx or Tx (+ 5 J2K monitoring streams) + 2 Rx + 1 x 1Gb Data Video streams, inband telemetry, and data are managed All can be set to 100% QoS or data can be set to lower (opportunistic) priority Edge Adapters Edge Adapters Each trunk port has programmable head room for management, and programmable value for policing data traffic. TX <Example> RX 4Tx/4Rx 5 x Tx = 7.5 G TX RX Ethernet 5Tx/2Rx/1E 5 x J2K = 375 M Management = 100 M Policed Data = 2 G

11 Important Project Requirements Redundancy Edge Adapter Dual Trunk Ports Each Gateway interface unit has two trunk ports. Each port is directly connected to IP-VR No more than 6 HD- (1080i or 720p) per 10Gb port IP-VR#1 IP-VR#2 CNT# 1 #1 #2 #3 #4 #5 #6 #7 #8 CNT# 2 IP-GW

12 Important Project Requirements Distributing Video Streams Uplink bandwidth for video is statically assigned based on the installed services. The IP-VR keeps track of the active bandwidth for video at the egress side of each port to prevent over-subscription (each table entry has a bandwidth which is summed) Active Services Active Services Active BW Management CN T#1 #1 #2 #3 #4 #5 #6 #7 #8 CN T#2 CN T#1 #1 #2 #3 #4 #5 #6 #7 #8 CN T#2 IP-GW IP-GW

13 Important Project Requirements Cabling and Patching Switch and Patching Source Coax Normal Jack DA Coax Normal Jack Gate way Fiber Jack & Jumper 10Gb Switch Fiber Jack & Jumper Gate way Coax Normal Jack Dest J2K Stream Fiber Jack & Jumper 10Gb Switch Fiber Jack & Jumper 1Gb Switch RJ45 Patch J2K Dec HDMI Coax Normal Jack Dest Ethernet Source RJ45 Patch Gate way Fiber Jack & Jumper 10Gb Switch Fiber Jack & Jumper Gate way RJ45 Patch Ethernet Dest Ability to patch around failed path

14 Important Project Requirements Redundancy Management for Data Services and Inband Telemetry Redundant paths are automatically managed by a redundancy management protocol (GSRP*). One IP-VR is assigned to a group of VLANs. L2 loops are avoided based on a group of VLANs Upon link or switch failure, the alternative path is automatically enabled. IP-GW IP-VR VLAN Group A VLAN Group B L2 SW Redundancy Management Protocol L2 SW IP-VR *) GSRP is a proprietary protocol, supported by Alaxala, NEC, Hitachi

15 Important Project Requirements SDN per flow forwarding based on MRF (Media Rapid Flow) rapid IPbased provisioning Emulating crosspoint switch performance(<30ms switching time) Centralized bandwidth and route management Perfect Non-blocking for Video traffic Optimized for 100% throughput, maximum forwarding rate and memory allocation to priority queues Hitless protection switching and clean switching to new source Genlock over IP(SMPTE2059-1/2) File/data transfer over IP, sharing the network with video streams 2016 Media Global Links.

16 Important Project Requirements Management System Structure Ember + interface to control panels for legacy systems Provisioning/Activation Service configures Edge Adapters, Core Switch, J2K Decoders NetGazer NMS monitors the entire system and forwards alarms to the customer s alarm system. Client GUI SNMP Trap/Alarm Forwarding HW Panels Legacy System NetGazer: Network Management System Northbound API API Layer to Client Provisioning Control Service SNMP Agent Server Service; VM, Cloud Architecture IP-VR IP-GW L2-SW IP-Decoder IP-GW IP-VR L2SW J2K-Decoder MRF Agent MRF Agent CLI SNMP Agent SNMP Client CLI SNMP Agent SNMP Agent MRF Agent CLI, JSON, OAM
