Optical video/audio signal distribution network for a broadcast center using WD/TD/SD hybrid multiplexing

Today's TV broadcast centers require large capacity and flexible routing networks for handling uncompressed serial digital video signals. Fuji Television's new broadcast center employs a newly developed optical video/audio signal distribution network This paper describes the design concept, the system structure, and the performance of the optical network. A wavelength-division and time division hybrid multiplexed (WD/TD) optical network has been applied to the broadcast center. This type of optical network is attractive for a broadcast center application, because of its large capacity, multiple format handling, and flexible operation capabilities.
