Astra Deploys Broadcast MediaCluster Digital Video Server / First Transmission of Theater Quality AC-3 Audio

International announced that ASTRA, Europe's leading direct-to- home satellite system, has deployed the SeaChange Broadcast MediaCluster video server system to streamline operations. ASTRA is using the advanced video server system to store and manage two continent-wide promotional channels called ASTRA-Vision, featuring 7 languages and the first-ever delivery of Dolby Digital AC-3 audio. Serving 77 million TV households in Europe, ASTRA is the leading European satellite system. It selected the Broadcast MediaCluster (BMC) for its advanced networking capabilities and critical fault-resiliency in support of its highly automated operation. "SeaChange's video server system truly capitalizes on digital technology's advantages and that is why it is the most appropriate system for ASTRA," said Steve Lachard, Earth Station Engineer, ASTRA. "The Broadcast MediaCluster provides the powerful combination of automation, network connectivity and reliability, together with high-quality MPEG-2 digital video and audio." ASTRA's four-node Broadcast MediaCluster delivers 10 channels of MPEG-2 video at data rates up to 24Mb/sec., and is capable of storing over a terabyte of video, equal to almost 100 hours. ASTRA's BMC system is integrated with a number of production systems, including vision and audio mixers, character generators and others, with automation provided by Omnibus Systems. MediaCluster Technology The MPEG-2 4:2:2 Broadcast MediaCluster supports multichannel play-to-air applications including program origination, commercial insertion and time shift/delay. The system employs SeaChange's patented RAID2 ('raid squared') technology which performs RAID-5 striping on the disk drives on each node (computer) and also across all the nodes in the cluster. Only one copy of any video file is required, thereby dramatically reducing storage requirements and also providing fault resilience. Nodes are available with 9GB, 18GB or 36GB disk drives. Expansion increases capacity to hundreds of hours of storage and 20 I/Os. The Broadcast MediaCluster will include full support for reliable storage and delivery of MPEG-based DVB or ATSC Transport Streams in the fourth quarter of 1999.
