A system is described for the transmission and routing of uncompressed digital HDTV signals for use within studio centers. Interfaces have been developed in RACE Project 1081 which allow the transmission of uncompressed digital HDTV signals on optical fiber using the CCITT synchronous digital hierarchy (SDH). Two channels of HDTV or a combination of HDTV and other standard video formats can be carried in a single STM-16 signal. The interfaces can be used with the broadband customer premises network developed in RACE Project 1036 which uses a combination of optical wavelength and electrical time-division multiplexing (WTDM). This network can satisfy all the routing requirements of a modern studio center but also has the capability of routing HDTV signals. The network has a total payload capacity of over 38 Gbits/sec and can therefore carry up to thirty-two HDTV signals. The results of recent experiments are described where the HDTV interfaces were used with a partially populated WTDM network.
