摘要

DIRECTV began construction of its new HD playout area in May 2007 with a tight deadline: nine months from inception to deployment of up to 80 fully redundant new HD channels based on a system architecture that was flexible enough to rapidly accommodate a range of further services when the need arose. The number of channels, the short timescale and the decision to run the operation on IT server hardware made this an innovative and ambitious project. Based within DIRECTV'S existing facility in the Los Angeles Broadcast Center, the equipment for these new HD services needed to fit into a smaller area than is typical with a conventional, multivendor installation. OmniBus iTX was chosen for its versatile features and performance, space efficiency and because, as an integrated system, it can be installed and commissioned in a comparatively short time. Integration needed with DIRECTV's proprietary business and engineering management systems required custom development from OmniBus. Web services and high-level interfaces were used to develop further solutions for specific requirements such as real-time connectivity for schedule updates, real-time alerts to provide feedback to the engineering monitoring system and interfaces to DIRECTV's conditional-access systems to automate the insertion of access information into playlists.
