Video Server Technology: Sharing media with media area networks
Broadcasters re-purposing their high-value content over a variety of distribution media require the greatest possible efficiency and limitless access to media access within their facilities. These environments support applications where distributed, networked servers are best suited - and others where a work group approach using shared storage is more appropriate.While there are many implementations of storage area networks, there are few that can rise to the challenges posed by the demanding world of broadcasting - one that requires guaranteed isochronous data delivery across multiple channels and the ability to shuttle and jog on any channel, at any time, without impacting on-air reliability. User requirements demand file access from standard operating system calls allowing the storage array to serve any NT application, as well as robust play to air capability and a fault tolerant architecture. Such systems must operate with mixed compression formats and at varying data rates storing all within the same array. In addition, simply working in a shared storage environment does not guarantee interoperability. When different applications are involved in content creation, there must also be a solution to interoperability at the application layer that allows applications to search each other's metadata databases to locate content.This article explores a universal, Microsoft Windows NT-based infrastructure that promises to overcome the shortfalls of today's shared storage solutions. This technology, known as Media Area Networks, or MAN, will provide broadcasters an extremely flexible environment for attaching devices to their media SANs. MAN leapfrogs current shared storage technologies to enable seamless integration of third-party applications, reduce disk storage requirements, provide centralized asset management - all while delivering real-time quality of service for on-air playout and record.
