    "abstract": "Conventional methods for routing signals in a television plant, with their associated limitations, may include patch panels, passive switching, and electronic routing switchers. The production-quality color television routing and measurement system concept discussed here utilizes a modern, standard production, video/audio routing switcher as the central system element. This system eliminates the need for testing through the production switcher (the conventional method) by providing facilities for accurate testing of all sources at the engineering area during full operation. This is of particular significance where unattended switchers are in operation. Other precision timing benefits become possible and practical, further reducing the number of chances for errors. The ‘path length accuracy” principle is demonstrated in a practical operational model.",
