NEP Australia – The Andrews Hub
A case study for IP-based video production

TU Ilmenau – Media Event, 20.11.2018

Project History

Request for proposal (RFP) released to market for the provision of centralised production facilities in August 2016

The key drivers were:

Production Efficiency
    • Utilising Production Personnel across different geographic locations without moving them
    • Utilising Production Personnel for a full work day, or in some cases more than one in a day

Cost
       •   Minimise Production Personnel travel time
       •   Minimise Per Diems
       •   Minimise Hotel Accommodation
       •   Minimise Air Travel

       There could be no compromise in the quality on air, either technical or production

NEP embarked in one of the most comprehensive, and ground breaking broadcast projects.
The “anyone anywhere” concept was born

Dimensions

Highlights

•   HUBs and iOBs form production centers as needed for each production

•   29 Venues are connected to the Andrews HUB today

•   Diverse and fully redundant 50Gbs Network at 90% of the 29 Venues

•   SMPTE 2110 and/or VC2 as required by bandwidth availability

•   SMPTE 2059 (PTP) for System Wide Timing

•   VSM Control and monitoring of multicast streams

•   NEP clients are connected by 100Gbs Hitless Network to the Andrews HUB, meaning they are able to be uncompressed and hitless from the
    venue to the broadcaster

Why IP?

•   NEP’s concept of ‘anyone anywhere’, this only works in an IP environment

•   Transport from the venue to the hub is IP anyway
                                                                               Twice this much cable
•   It saves cost and time in deployment                                            @ 40Gbps

•   NEP needs to innovate and move technology forward

•   NEP COULD NOT HAVE BUILT THIS IN TIME IN SDI!

VSM – Control

For the end user, the experience is the same. We have changed almost every single device behind this control panel, the way the signals move and the distance we move
them. Can you see the difference?                                                                                                                                12

Standards

•   SMPTE ST2022-6 – for essence transport (V, A, MD all-in-one)
•   SMPTE ST2110 (-10, -20, -30, -31) – for essence transport (V, A, MD
    separately) and synchronization
•   SMPTE ST2022-7 – for path redundancy (seamless protection switching,
    hitless merge)
•   SMPTE ST2059-2 – for timing (SMPTE Profile for IEEE1588 PTPv2)

                                        The nice thing about standards is that
                                         you have so many to choose from.

Challenges – Network

•   ST2110
    • 1 SDI signal → 18 multicast streams (1 video stream, 4-16 audio streams,
      1 HANC/VANC metadata stream)
•   Switching speed:
    • SDI router max 3 frames for any number of input / output combinations
    • Network ~20-40ms per stream, scales linearly (300 signals = 300*18 flows
      = 216 seconds [5400*40ms] switch time)
•   PTP transport over WAN links
•   Bandwidth management

                                                                                 16

Challenges – Security

                        17

Challenges – Monitoring

 IT infrastructures are…
 ➢ entirely abstract
 ➢ extremely powerful
 ➢ highly dynamic

 Monitoring is key!

Outlook / Trends

•   100GbE → 200GbE → 400GbE → more!
•   Virtualization
•   Broadcast as a Service
•   Automated production
•   Programmatic network control
