ESPN transmission facility
ESPN's continued rapid growth was the catalyst for a new transmission facility, which opened on July 15, 2010, and was designed with a 10-year vision of growth. It consists of a 5400sq-ft control room, two equipment rooms and a network operations center to support ESPN's private fiber network. The control room was designed to provide the engineers better tools to increase their productivity and to optimize work space.
The consoles in the control room are sleek and display minimal physical equipment. By using GUI displays, ESPN was able to move the hardware to the equipment rooms, thus eliminating heat and noise in the control room.
The heart of the facility is a new automation system, the intelligent resource manager that was developed in collaboration with Evertz Microsystems. This system uses a variety of discrete control systems. The intelligent resource manager provides a common user interface to optimize the use of resources through a real-time data exchange with ESPN's internal event scheduling application. Resources for an event are reserved, configured and routed with just a few mouse clicks, which has yielded significant improvements in
Due to the tremendous growth of ESPNet, the private fiber network that is engineered, maintained and operated by ESPN's network transport team, a unique network operations center was required. Net Insight's Nimbra Vision platform provides service provisioning, bandwidth monitoring and alarm notifications for network events across all nodes in the system, which allows full view and enables fast response times to any network event on a 24/7 basis.
The new transmission facility is connected to various buildings on the ESPN campus via a large Sumitomo air-blown fiber network with more than 2300 connections. Available technical space increased five-fold with respect to the previous facility: 57-unit Stantron equipment racks expanded the usable vertical space by 1500RU. The new facility also houses a multiviewer platform system that provides 304 video inputs, 80 graphical inputs and 64 video outputs.
The facility is 3G-compliant with two 1152-squared Evertz EQX 3G routing systems, two 576-squared ASI routing systems, two 256 x 128 L-band routing systems and dual MADI routers. Streamlined management systems and consolidation of core routing systems reduce the complexity of the day-to-day operational workflow.
Best-practice optical and electrical cable management systems have greatly enhanced the integrity of infrastructure installation and maintenance, eliminating clutter encountered in a shared space. The use of embedded audio has expanded audio channel-handling capability from eight to up to 16 channels, and the Consumer Experience Lab allows for real-time evaluation of ESPN's end product, including 3-D and 5.1 discrete surround sound.
ESPN uses dual-redundant UPS power distribution across two diverse, firewall-protected equipment rooms. All air-critical equipment has been distributed across two rooms for maximum operational resiliency in the event one room is compromised.
