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 Initial meeting with arena TV was held around the time of IBC 2015. From this we learned that Arena TV had some very specific requirements: Arena TV wanted the Truck to be unique in the market place, and to be very pioneering. Arena wanted a solution with a COTS IP switch at the heart of the truck – No SDI Routing. The Solution had to be Standards Based so as to allow for technologies offered by other companies to be used within the truck as and when required. Arena TV wanted to adopt the IP standards around at that time but also wanted to understand what other IP standards were coming and required a solution capable of adopting these as they became available. Format Agnostic – Support multiple formats. So, whilst OBX needed to be a UHD truck, it would also be required for 1080p and 1080i productions. So a multi-purpose deign was essential. Arena understood that OBX was to be a significant investment and so it was important that it would be able to support upcoming challenges such as HDR and HFR productions also. Future Ready – High Dynamic Range and High Frame Rate Arena TV were keen to achieve a Reduction in cabling and with it a reduction in weight. Must remember that OBX would be driving up and down the U.K. attending sporting events and so a reduction in fuel costs was clearly good news. Also, less cabling improves access within the truck which becomes important when maintaining and changing set-ups. As cost neutral to a traditional SDI based truck design (albeit Quad-Link)
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 Solution needed to support 32 x UHD Cameras (not a small truck, needs to support Premier League Football Matches) 12 x UHD Replay Systems 1 x UHD Production Switcher 47 Multiviewers (plenty of monitoring positons for Production, Audio, VT, Engineering or on the Tailboard). Important to remember that the deliverables to the client have more than doubled. No longer HD with 5.1 and Stereo Audio Mixes, we are now having to provide UHD with Dolby Atmos. 5.1 and Stereo plus an HD Variant and a Clean version for the World Feed and so on… As is usually the case at large sporting events, Arena understood that OBX would not be the only IP truck that turned up, other OB’s would require a feed, trucks for uplinks, trucks for graphics and so this connectivity would also need to be catered for. In light of this GV provided a fairly unique solution whereby the OBX Tailboard offers bi-directional connectivity. So, Input ports could become output ports by having the control system switch them. We also provided a flyaway frame that could be provided to the Graphics truck so they could patch up to OBX and provide an IP connection back to OBX. As OBX was going to be the first of three trucks, it would be a nice feature if we could hook all three trucks up using IP as opposed to large umbilical's of SDI.

High Level Overview BLAN is Broadcast LAN Management of all broadcast devices Media LAN is all TR-04 Media Transport Grass Valley Kayenne Production Switcher Pretty much the largest one we have, fully populated. Even though we were using IP connectivity, the ability to work in 2SI mode allows us to support 4M/E’s when working in UHD. On-board Modular IP Gateway Interfaces, also supporting TICO. All GV devices capable of providing a TICO Encoded stream also provide a 1080p monitoring stream. So, the TICO stream is used for the Production Switcher, it can go to the Tailboard whilst your 1080p monitoring stream can be sent around the truck for use by other devices such as the Multiviewers.
