Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording time extended digital recording apparatus and method, and more particularly, to a digital recording apparatus and method capable of variably extending a recording time recorded on a digital video tape.

For the purpose of the present invention, a frame dividing signal generating means for outputting a control pulse signal for variably dividing a frame inputted by receiving a frame-based synchronizing signal, and a control means for controlling the number of pulses of the time control pulse signal in the frame dividing signal generating means And recording control means for selectively changing a frame of the recording data in the modulating means recorded on the recording medium.

As described above, according to the present invention, in the digital VCR system, the same image quality is ensured even when the digital VCR is used in high image quality and repeated recording by simple control, and the amount of recorded information is varied according to the characteristics of information to be recorded, The recordable time can be extended.
