    摘要: An apparatus for recording and/or reproducing video signals is disclosed. First and second video signals from an imaging unit and an external video input, respectively, are coupled to the apparatus. A converter circuit selectively acts to form a time expanded or time compressed version of the input video signal depending upon whether the input is the first or second input signal. In the former case, the first input video is recorded on a recording medium and the time expanded version coupled to a display, while in the latter case, the second input video signal is coupled to the display and the compressed version recorded. During the reproduction, the converter circuit also generates a time expanded version of the reproduced signal for coupling to the display.
