Digital Networking Solutions for Enabling Metropolitan and Wide Area Digital Video Transport Networks

摘要

This technical discussion paper introduces 3 technology enablers that, when integrated, offer a solution to dramatically improve the present day digital video storae and access paradigm in the roadcast industry. when combined, Storage Area Networks (SAN), Fibre Channel, and fiber optic Dense Wavelength Division Multiplexing (DWDM) enable the transport and sharing of compressed and/or uncompressed digital video files among multiple users at different office locations. This capability is vital to the broadcast industry because digital video formats are used extensively and collaboration between production houses and broadcasters is essential. The paper will include an introduction to the technology enablers and will demonstrate the technical feasibility of creating a high speed, private, digital video file transport network in a metropolitan area. These new technologies present an opportunity for high bandwidth data and video file transport not previously attainable with traditional networking approaches such as SONET. As well, the migration to uncompressed HDTV signals (1.5 Gbps) and possible video wide area network applications will also be explored.
