Abstract
A television signal equipment assignment matrix comprises a plurality of ports respectively connected to video tape recorders and to edit controllers for the video tape recorders, passive switches for effecting connection between a selected two of the ports under control of an externally supplied control signal from an operator's control panel whereby an appropriate such control signal can cause a selected edit controller to be connected to a selected video tape recorder to enable it to be controlled by that edit controller and for commands and status reports to pass therebetween, a further switch for cyclically or randomly tapping the connections between the video tape recorders and the edit controllers to derive the commands and status reports, and a display for displaying indications in dependence on the derived commands and status reports and the physical connections made between the video tape recorders and the edit controllers.
