Apparatus for recording video signals at a plurality of different recording speeds |
摘要 |
A video signal recording apparatus for recording a video signal on a magnetic tape includes an oscillator which generates an oscillation signal; a variable frequency divider for frequency dividing the oscillation signal; a control circuit for controlling the frequency-dividing ratio of the variable frequency divider in accordance with the speed of advancement of the magnetic tape during the recording operation; a frequency divider for generating a plurality of synchronizing signals in response to the output of the variable frequency divider; a camera including an image transducer from which the video signal is obtained in correspondence to incident light from an object image projected on the image transducer, and a transmission device for transmitting the signal from the image transducer at a rate determined by the synchronizing signals; and a recording section including a processing circuit for separately processing the luminance and chrominance components of the transmitted video signal, and at least one transducer for recording the processed video signal on the magnetic tape in response to the synchronizing signals, wherein the video signal is always recorded on the magnetic tape in the same format regardless of the speed of advancement of the magnetic tape during the recording operation.
