Transporting Production/Mastering-Quality Digital Video Signals through the Public Network using SONET/SDH and ATM Technology

Many video production and post-production organizations have changed over to digital facilities as the advantages of an all-digital plant have become more apparent. Along with this move to digital origination, storage, routing, and editing, the need has arisen for transporting high-quality digital video signals over long distances. Means for transporting uncompressed digital video signals have to date relied upon fiber optic overlay networks, but these networks are limited in transmission distances and require dedication of the fiber to solely video transmission. — This paper describes a method for transporting a variety of high-quality, standards-based digital video signals through the global SONET/SDH public network infrastructure by using cost- effective, flexible ATM technology. The difficulties of creating non-standard SONET/SDH tributaries within concatenated Synchronous Transport Signals are bypassed by using ATM-based multiplexing techniques. This approach greatly simplifies the design of SONET/SDH video terminal equipment, while permitting transmission of lower-speed data channels along with the high-speed video signals along the SONET/SDH backbone.
