Abstract
A recording apparatus for a high definition video cassette recorder, comprises a tape discriminator for checking for the presence of a hole on a specified position of a tape to discriminate whether the tape is of the normal-VHS type or the super-VHS type, a clock signal generator for generating a clock signal of a desired period in response to an output signal from the tape discriminator, a frequency divider for frequency-dividing the clock signal from the clock signal generator by an integer N, a first switch for selecting either the clock signal from the clock signal generator or the frequency divided clock signal in response to the output signal from the tape discriminator, a video data separator for separating intra-frame data and inter-frame data from an input digital video signal in response to the clock signal selected by the first switch and outputting the separated intra-frame data, a second switch for selecting either the input digital video signal or the intra-frame data from the video data separator in response to the output signal from the tape discriminator, a video data formatter for formatting an output signal from the second switch in response to the clock signal f…
