Abstract
A plurality of video devices, that is, a PC card controller 17, an MPEG2 decoder 18, a P1394 controller 20, and a video capture 31 have each a motion-picture output port connected to a video/audio dedicated bus 4, as well as an interface with a PCI bus 2. Hence, any motion-picture source can be transferred directly to a display controller 14 through the video/audio dedicated bus, without using the PCI bus 2. Various motion-picture sources can therefore be efficiently displayed.
