Abstract
In a video broadcast or production plant including first and second video sources which provide first and second digital video signals respectively at integer related frame rates, the video sources are operated so that the first and second video signals are aligned at a reference time. Switch points for updating a router in the plant are defined by measuring lapse of time from the reference time.
