R&D Report 1996-14 : WTDM Pilot Installation. A report on the work of RACE Project 2001 C.D. Mathers (editor) The BBC has led two RACE-sponsored projects to develop the technology for a fibre-optic based video signal router. In the first project, R1036, prototype equipment was developed; a demonstration in 1992 showed that optical routeing was not only feasible, but could accommodate different signal formats such as serial digital 625-line and uncompressed EU-95 HDTV. In a second RACE Project, R2001, which is the subject of this Report, the equipment was improved, production-engineered, provided with a user-friendly operational interface, and demonstrated in a working broadcast environment.
