HBO Communication Center was built in 1983 as a distribution center. The HBO Communications Center is protected by redundant power distribution, keeping it in operation for 18 days without outside fuel refills. In addition to an advanced server infrastructure, the HBO facility includes a main master control suite and three control rooms. The MC suite monitors 32 channels internally and is equipped with a full wall of Barco VGA monitors, four Panasonic plasma displays, a New Point Technology alarming system and Barco Vivaldi monitor display hardware. All distribution of on-demand content comes from the HBO Communications Center in Hauppauge, N.Y., from which HBO distributes approximately 150 to 200 hours of content to cable systems across the nation. HBO's digital facility and its systems incorporate highly automated Sun/Hitachi and Profile servers and Open SAN systems that have resulted in the development of electronic workflow architectures. This has increased the efficiency and allowed HBO to put additional safeguards in place to continue its mission-critical distribution.
