Abstract:
A video signal recording and/or reproducing apparatus for recording and/or reproducing a standard television signal and a high definition television signal having a broader band than that of the standard television signal, comprising:recording mode presetting means for presetting one of a first recording mode in which said high definition television signal is recorded and a second recording mode in which said standard television signal is recorded;interpolation and rate doubling processing means for applying scanning line interpolation and rate doubling conversion processing for the standard television signal to output a double rate signal;high definition processing means for applying to the double rate signal outputted from said interpolation and rate doubling processing means a scanning line conversion processing to convert the double rate signal into a signal having a same format as that of the high definition television signal and a same field frequency as that of the standard television signal and an aspect ratio conversion processing to convert the double rate signal into a signal having a same aspect ratio as that of the high definition television signal;a high definition television signal recording and/or reproducing means for recording and/or reproducing a high definition signal in accordance with a given format; andservo control means for performing servo control in given recording and reproducing modes on recording and reproducing, respectively in response to an output from said recording mode presetting means;one of said first and second recording modes being selected in response to an output from said recording mode presetting means so that the high definition television signal is recorded and/or reproduced by said recording and/or reproducing means when the first recording mode is selected and an output signal from said high definition processing means is recorded and/or reproduced by said recording and/or reproducing means when said second recording mode is selected.
