HD-SDI VIDEO TRANSPORT OVER OPTICAL NETWORKS
OPTICAL TRANSPORT OF UNCOMPRESSED HIGH DEFINITION VIDEO

Broadcast and entertainment providers are expanding their capabilities to deliver more high definition (HD) content to satisfy the growing hunger of viewers for high quality HDTV programming. Broadcasters have been upgrading their networks to broadcast more channels in HD but to complete this picture, the broadcasters themselves need to access HD content from studios, live events (sports, news and political conventions) and postproduction companies. Although transporting SDI and HD-SDI can be achieved by compressing these signals, the quality is enhanced when these video signals are transported in their uncompressed format. Transmission of uncompressed HD video content creates a new market for service providers, serving customers with the need for very high transport capacity.

Increasingly, content providers and production companies are looking for transport of uncompressed digital video signals, regardless of format, over long distances without degrading the original quality. Production companies are now starting to digitally transfer SDI and HD SDI content over fiber for purposes of pre-and post-production, editing, and distribution, live or otherwise.

The key to addressing this market need is a solution that eliminates the need for compressing video signals before transport and provides the necessary flexibility for transmitting over short and long distances for local, metro, regional and wide area distribution.
