Television Technical Facilities at Maison de Radio-Canada

Integrated circuit techniques and a systems approach are making it possible to centralize equipment and facilities at Maison de Radio-Canada and to permit them to be assigned as needed. Such centralizing is desirable to meet the timing requirements of color TV, but it requires remote control of switching, delegation, machine control, etc. Particular attention is given to a Program Routing Switcher (which routes program audio and video from source to distribution) and a Control Assignment Switcher (which handles the point-to-point assignment of intercom, pulses, and remote machine control). A minicomputer is employed to control the Program Routing Switcher and perform code translations and validity checks; provision has been made to computerize the Control Assignment Switch also. Other systems and subsystems treated include studio vision mixers, TV audio consoles, the TV intercom system, live camera channels, and VTR and telecine chains.
