The Design of Film Review Rooms for Color Television

The Canadian Telecasting Practices Committee (CTPC) has issued its practice CTP 1, “Viewing Rooms for Evaluation of 16mm Color Film for Television.” CTP 1 is based on work done by the CBC to improve the quality of television film programs. CTP 1 has been applied for the first time in the CBC Toronto Film Dept. Four film review rooms have been built with a common and separate projection room; the rooms can be operated independently of one another. The purpose of each room is to evaluate film quality from the point of view of the television viewer. To this end the screen has been built to look like a 25-in television monitor; a surround light has been provided. The listening environment has been designed to allow adequate evaluation of the soundtrack. A working desk, at the proper distance from the screen, includes remote controls of all projector circuits. It also houses a film timer and audio-level monitoring and control. The decor is pleasing and comfortable, as required for long periods of work by the film evaluators. Salient features of the equipment are described; of particular interest is the method of obtaining the surround light from the side of the lamphouse of the 16mm projector using a separate optical system.
