A method and apparatus for controlling a memory to record data received at random rate into a fixed rate and to reproduce the data recorded in a fixed rate includes a shuffle memory with a plurality of memory banks for recording and reproducing a digital data at a fixed rate and the smoothing memory is also allocated to a surplus region of the shuffle memory. By using a serial clock and a plurality of FIFOs, the data can be efficiently recorded and reproduced without collision.

Method for controlling memory and digital recording/reproducing device using the same

A video signal recording and reproducing apparatus for a digital video cassette tape recorder by which it is possible to judge the transmission amount of the digital data inputted from a digital source, the type of the video tape, and whether or not the tape is recorded in accordance with the judgment result, for thus automatically controlling a recording mode and a reproducing mode, which includes a tape type detector for judging a tape type in accordance with a recordable wavelength of the video tape on which a digital signal is recorded; a data rate detector for detecting and judging a data transfer rate of a digital signal, and a controller for varying a recording or reproducing speed in accordance with the judged tape type and the data transfer rate of the digital signal.

Video signal recording and reproducing apparatus for digital video

An improved video signal recording and reproducing apparatus for a digital video cassette tape recorder by which it is possible to divide, record and reproduce a digital video signal on a low density video tape into multiple tracks based on the amount of data recordable on one track of a high density video tape by controlling a recording/reproducing speed and a tape running speed in accordance with a judgement of the type of the video tape having a predetermined recordable wavelength. The apparatus includes a detector for detecting the type of the video tape in accordance with a recordable wavelength of the video tape, a judgement section for judging the type of the tape by receiving a detected tape type signal from the detector, and a controller for controlling a recording and reproducing speed in accordance with the judged tape type.
