1. A reproducing apparatus which synchronously reproduces motion picture data and sound data provided separately from each other, comprising:

  • a motion picture reproducing unit; and

    a sound reproducing unit, wherein;

    said motion picture reproducing unit comprises;

    a motion picture decoder for decoding said motion picture data; and

    a display control unit which converts the motion picture data decoded by said motion picture decoder into an image signal for a display unit, and outputs the image signal to said display unit;

    said sound reproducing unit comprises;

    a sound decoder which decodes said sound data;

    a data buffer which stores the sound data decoded by said sound decoder; and

    a sound conversion means which converts the decoded sound data stored in said buffer into a sound signal for a sound device, and outputs the sound signal to said sound device;

    said display control means asserts a synchronous reproducing start signal according to output of said image signal corresponding to a top frame of said motion picture data; and

    said sound conversion means starts output of said sound signal according to assertion of said synchronous reproducing start signal.
