Abstract: A flexible video information analysis apparatus stores a video information data base and a plurality of moving image content analysis algorithms for analyzing the video information in the data base. A user can manipulate a mouse to select one of the analysis algorithms. The selected algorithm is used to analyze video information in the data base.

Abstract: Signals from sixteen video cameras are selectively captured using three video decoding circuits. Each decoding circuit is selectively connectable to each camera. Each of two A/D converters is selectively connectable to each of the three decoding circuits. Two video field buffers are provided to store, respectively, the digital video signals generated by the two A/D converters.

Abstract: A structure for supporting a plurality of recording medium drive units includes a base member supporting a floppy disk drive and a DAT drive, an intermediate member supported on the base member and supporting two hard disk drives, and a top member supported on the intermediate member and supporting one or two hard disk drives.The recording medium drive unit support structure is mounted within a housing, within which are also housed a motherboard, a second printed circuit board and a third printed circuit board. The motherboard has mounted thereon a microprocessor for controlling storage of video data on at least one of the hard disks. The second printed circuit board has integrated circuits mounted thereon for receiving plural streams of video information and for selecting for storage fields of video information included in the streams of video information.
