ABSTRACT:
A digital switcher of this invention comprises a matrix switcher section 11 adapted so that a plurality of serial digital video signals are inputted through respective input buses, a control section 12 for carrying out operation control of the matrix switcher section 11, signal processing sections 13A, 13B . . . connected to a plurality of output buses of the matrix switcher section 11, an input detector 14 connected to one output bus of the matrix switcher section 11, and an error detector 15 connected to one output bus of the matrix switcher section 11. An approach is employed to control the matrix switcher section 11 by the control section 12 with respect to a plurality of digital video signals inputted through respective input buses to thereby selectively detect presence or absence of input and occurrence of error by the input detector 14 and the error detector 15 connected to one output bus of the matrix switcher section 11.
