COMPUTER SYSTEM AND PC CARD CONTROLLER USED IN THE SAME

摘要

PROBLEM TO BE SOLVED: To hold high versatility while reducing restriction in the number of the input/output terminals of a PC card controller and enabling various function circuits for a signal to be outputted to a ZV port. SOLUTION: A system is provided with a PC card-PCI bus bridge 13 which is connected to a PCI bus 15 so as to control PC cards 11a and 11b connected to card slots 12a and 12b, detects that the PC cards 11a and 11b output a video/ audio signal at the time of outputting and outputs selection deciding signals a and b and a ZV signal selection synthesizing circuit 14 which selectively outputs the video/audio signal transmitted from the card slots 12a and 12b in accordance with the selection deciding signals a and b to the ZV port 18 to which a display controller 16 executing the display processing of a video signal and an audio controller 19 executing the output processing of an audio signal are connected.
