Patent ID: 8345164

Claim:
A video switching apparatus having a plurality of slots each for mounting any of a first input module capable of inputting any one of a plurality of predetermined types of video signals and performing processing, content of which varies depending on the type of input video signal and a second input module capable of inputting only predetermined one type of video signal, switching and outputting video signals of a plurality of channels input to input modules mounted to the plurality of slots, the video switching apparatus comprising: input setup data memory processing means for storing input setup data indicating a type of input module mounted to each of the plurality of slots and a type of video signal input thereto in memory means; detecting means for reading the input setup data from the memory means and detecting a slot having an input module mounted at present the type of which is different from a module indicated in the read input setup data; and input setup changing means for determining the type of video signal input to the first input module and causing the first input module to execute processing corresponding to the determined type of video signal upon detecting by the detecting means that the input module mounted at present to the slot is the first input module, wherein the first input module processes a type of video signals different from the second input module, and wherein each input module includes a frame synchronizing and resizing section that synchronizes and resizes input video signals and a local CPU that stores identification information of the input module.
