Abstract
A source original HD video signal Sof 24-frame rate is subjected to 2-3 pull-down process, thereby generating a 30-frame rate SD video signal S. The 24-frame rate time code added to the source video signal Sis described in the user area of the VITC data () inserted into the 30-frame rate video signal. The sequence numberindicating the order of fields in one sequence of the pull-down process is described in the user area of the VITC data () inserted in the 30-frame rate video signal. Inverse 2-3 pull-down process is performed on the 30-frame rate video signal recorded on tape, by using the sequence numberdescribed in the user area of the VITC data, thereby generating a 24-frame rate video signal. The 24-frame rate video signal is recorded on a hard disc. A nonlinear editing device () uses the 24-frame rate time code inserted in the user area of the VITC data, thereby generating an edition list that will be supplied to an on-line editing system.
