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. The third printed circuit board has mounted thereon a first digital signal processing integrated circuit (DSP-IC) for applying a data compression to the streams of video information, a second DSP-IC for controlling scaling and overlay mixing processes applied to the streams of video information, and a third DSP-IC for applying a moving image content analysis algorithm to the streams of video information. The first DSP-IC exchanges data with the microprocessor and transmits command messages to, and receives status messages from, the second and third DSP-IC's.
