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.

摘要： The video signal processing apparatus of the invention is an apparatus for processing a video signal superimposed on a carrier signal by digitizing. The video signal is sampled at a sampling frequency equal to 2n (where n is 2 or higher integer) times the frequency of the carrier signal to form 2n sample data per period of the carrier signal. After the formed sample data have been memorized in the sampling sequence, the corresponding 2n sample data to one period of the carrier signal are read in a different sequence from that when the aforesaid memorizing was carried out. Thus, the video signal can be processed by using means of simple structure.
