    摘要: In general, the inputted digital images of multiple channels are subjected to compressing and encoding utilizing a correlation between frames for each channel, and the compressed and encoded images are intermittently recorded in a recording medium. Then while a time interval of intermittent recording exceeds a predetermined value, digital images are subject to compressing and encoding in a frame, and are recorded in a recording medium. When compressing and encoding in a frame are performed for digital images, the digital images of multiple channels are recorded in a buffer memory in units of frames.

    摘要: A method and an apparatus for recording and playing back monitored video data for recording monitored video data generated continuously for a long time on a magnetic tape, with less S/N degradation by shortening the operation time of the VTR to suppress the degradation of the magnetic tape, recording head, and other mechanical items, wherein video signals from a video camera are converted to digital signals in an A/D converter, compressed and encoded in a compression encoder & decoder circuit, then transferred to a time axis compression circuit including the first memory, the second memory, an SCSI controller, and a hard disk unit, thereafter compressed on the time axis and recorded on the magnetic tape loaded in a D-VHS standard VTR via an I/F circuit. Compressing the video data from the compression encoder & decoder circuit on the time axis in the time axis compression circuit makes shorter the recording time of the video data on the magnetic tape than the actual recording time of the video camera, whereby the VTR is only required to record video data intermittently on the magnetic tape and that a general home VTR can be adopted as the above VTR, moreover the magnetic tape itself is prevented from damages.

    摘要: A hexadecimal/binary-coded-decimal (HEXA-BCD) hybrid address coding method for representing digital timing address of data storage device, wherein the first digit of the minute filed is represented in Hexadecimal format with four binary data bits, therefore the 0-9 is the same as the BCD coding while 11-15 (A-F) is an extension which allows the proprietary recorder to recognize the data storage device and generates the time address for the digital data storage device. Furthermore, a slight fireware change is made by extending the address look up table to 159:59:74. Hence the first digit of the time address must be represented in Hexadecimal which fully utilizes the four addressing bits in the M1 frame.

    摘要: A data recording/reproducing apparatus applicable to, for example, an editing system having a plurality of hard disk units arranged to be in parallel operated to record/reproduce a video signal to be capable of recovering abnormal data without any interruption with the operations for recording/reproducing continuous data. The operations of a plurality of data recording/reproducing blocks are managed in time by a time slot to use a period of a blank time slot if an abnormal condition appears in one recording/reproducing block to recover abnormal data with data recorded on another recording/reproducing block.
