Abstract
Abstract A shared video data storage system eliminates the need for a costly dedicated server and high performance network connection in audio/video media delivery applications. Instead of stations requesting material from a server and waiting for the data to be delivered across the network from the storage devices via the server, the storage devices are connected locally to each station. Access is arbitrated locally over a low performance (and consequently lower cost) network and access is provided directly via the storage interface.
