摘要:
A video signal recording and/or reproducing apparatus which is capable of recording and/or reproducing both high definition and standard television signals is disclosed. Accordingly, video signals of two systems such as the high definition and standard television signals can be recorded and/or reproduced by a single apparatus. The standard television signal is reproduced as a video signal having a high picture quality in a format similar to that of the high definition television signal. Even if the video signal to be recorded is the standard television signal, a reproduced picture having a higher picture quality than that of the standard television signal and having no distortion due to a difference in aspect ratios between the high definition and standard television signals can be provided.
