In June 2006, Showtime Networks Inc. (SNI) contracted Globecomm Systems to design, build and integrate a new network operations center to originate and transmit all SNI premium cable channels. This contract was awarded to Globecomm based on technical competence, depth of engineering support, proximity to New York City and competitive bid. The new operations center is located within the Globecomm facility.
Globecomm Systems finalized equipment selection in close coordination with the SNI design team, and ultimately the project was underway. Content acquisition played a significant role in choosing Avid’s MediaStream8000 as playout servers to maintain asset compatibility with SNI’s existing content library. SNI selected Harris’ Invenio digital asset management system for data essence with complete media tracking, indexing and archiving. The ingest subsystem’s workstation client handles digitization of content and QC functions prior to storage and archiving.
For physical asset management, SNI chose Masstech’s Massstore media asset management system for asset transfer from the multiple SAN domains to Spectralogic’s T950 robotic nearline archive library for long-term storage and protection. Harris’ H-Class automation takes the overall command and control mechanism from operator standpoint and provides the discrete instructions to all on-air equipment and resources. Miranda ImageStores and IntuitionXG are used for on-air graphic insertions and multilayer channel branding. The master control room is populated by large Panasonic professional 65in TFT flat-screen displays driven by Evertz’ MVP processors.
Signifying the order of signal workflow, the central equipment room houses 105 racks of broadcast equipment arranged in hot aisle/cold aisle to allow for maximum cooling. All equipment is clearly identified showing position and channel it supports. The facility was built with expansion in mind, so equipment was strategically located to allow for future growth while maintaining an orderly position. Cable trays and power were sized to accommodate any future load while minimizing disruption to the surroundings. Test and measurement functionality was deployed in every equipment row and supported by Harris’ VTM4100 rasterizers.
The most stressful part of any broadcast center deployment is putting it on the air. In just a couple of hours, instead of weeks or months, SNI transitioned 25 SD digital channels, three HD channels and one analog channel to the new broadcast center. That smooth transition was the product of intense planning as well as on-the-spot improvisation.
