Abstract: A matrix switcher which is applied to a switcher system of a broadcasting station, connects a plurality of input lines and a plurality of output lines at any points, and outputs source video signals to be supplied from desired output lines, more particularly a matrix switcher capable of easily confirming inputs corresponding to the outputs. An operation panel 40 of the switcher system in which a plurality of inputs and a plurality of outputs are freely connected by switching is provided with cross point buttons 40A for selecting a plurality of inputs, source name display units 40N for displaying the source names being input, delegation buttons 45A selecting a plurality of outputs, and output source name display units 45N displaying the source names to be selected and output. Where the predetermined output is selected in the delegation button 45A, the source name displayed on the output source name display unit 45N is changed to a source name newly selected by the cross point button 40A.
