Abstract
In the design of a digital television broadcast plant there are many issues to consider, such as digital format, tape format, embedded audio, and future advanced image formats. The heart of any broadcast plant is the central routing and distribution system. For CBC's new Broadcast Centre in Toronto, a large, multimatrix digital routing system was designed by a multidisciplinary team formed from several different companies. The design incorporated a complex, custom-designed control and supervisory system, and CRT-type custom control panels. In the absence of final standards and established test procedures for digital systems, new approaches were investigated to establish testing criteria and methodologies.
