Real World Design for IP Based Systems Jeff Rivera Diversified. Media & Entertainment
Introduction Diversified is an industry leader in the design and installa:on of a broad spectrum of custom engineered and integrated audiovisual media delivery solu:ons. They specialize in the use of audiovisual technology for complex and scalable professional broadcast, corporate communica:ons and digital signage networks providing businesses with the enhanced capability of crea:ng, managing and mone:zing original digital content. Jeff Rivera joined the broadcast industry 23 years ago at CBS Network in New York City aOer obtaining his B.S.E.E. at ManhaPan College, and achieved a M.S. in Computer Engineering shortly aOer that. He has been involved in numerous projects for major televisions networks as well as sports venues during the Digital and HD transi:ons and now the transi:on to IP.
Project Description • Number 4 Market sta:on migra:ng to a newly constructed facility • 3 Produc:on Control Rooms • 3 Audio Control Rooms • 3 Studios with flash loca:ons throughout/outside the facility • Newsroom & Weather studio • Off-‐site Satellite Farm
Why Transition to IP? • Technology Efficiencies
• Mul:ple signals carried on one cable -‐ bidirec:onal • Rou:ng and signal paths can change and scale with minimal reengineering
• New devices/func:onality can be added into the air chain with liPle to no down:me
• Take advantage of Network redundancy and protec:on schemes
• Workflow and Opera:onal Agility • Assignable & Scalable resources • Virtualiza:on/Cloud Services
• Geographical Flexibility
• Operate over longer distances • Alterna:ve to Satellite
Where to Start? • Choosing a Standard • What is available at the :me of delivery? • ASPEN • SMPTE RDD 37 -‐ Uncompressed video over MPEG-‐2 TS • SMPTE ST 302 -‐ AES3 audio over MPEG-‐2 TS • SMPTE ST 2038 -‐ Metadata over MPEG-‐2 TS • SMPTE 2022-‐6 -‐ SDI encapsulated over IP • SMPTE 2022-‐7 -‐ Seamless protec:on switching • SMPTE 2110 -‐ Essence based streams over IP • Uncompressed • Under development
Equipment Selection • Switch fabric and produc:on equipment selected to support SMPTE 2022-‐6/7 • Not all devices IP capable • Need IP Encapsulators and De-‐encapsulators
It’s All About Bandwidth • 10GB bi-‐direc:onal connec:ons • 3x 3G signals fit on one connec:on
• 1 connec:on per device wastes tremendous bandwidth • Need signal aggrega:on to bePer u:lize bandwidth • Some devices are source or des:na:on only • Display monitors for example
Infrastructure • Switch fabric has 40GB ports on MPO-‐12 connec:ons • How does one get 10GB connec:ons?
• MPO-‐12 to quad DLC breakout cables • MPO-‐12 to DLC Demarc panels/ cartridges
What to Do With Audio • AES67 compa:ble devices • Typically 1G connec:ons • Need signal aggrega:on • Some devices are source or des:na:on only • Speakers • Microphones
