Abstract
An object of the present invention is to provide a digital signal recording method and a digital signal recording apparatus, capable of readily producing a signal used to reproduce in a trick play mode from a digital compression video signal. The above-described object of the present invention may be achieved by such a digital video signal recording method for recording a first compression frame signal compressed without using a correlation between frames, and a digital compression video signal having preselected bytes of a packet format constituted by a second compression frame signal compressed with using the correlation between the frames, in which a third signal made of a packet containing the first compression frame signal is produced, and then is recorded in combination with the packet of the digital compression signal.
