Method for jump-reproducing video data of moving picture coded with high efficiency |
摘要 |
A disk stores data groups (GOP) of compressed picture data arranged over sectors. A 1st data indicative of a compression method and a 2nd data indicative of the presence of the GOP are contained in a leading sector. Data D (independent frame) is located at the head of the GOP. The 1st and 2nd data and GOP are aligned in order. The 1st data related to a 2nd GOP is detected after data D of the 1st GOP is reproduced to reproduce data D of the 2nd GOP. Data D arranged by an interval in the GOP are reproduced. In a quick traverse/reverse mode, a 2nd data D next to a 1st data D already reproduced is detected from a position of the GOP corresponding to a value obtained by subtracting/adding a fixed value from/to an integerfold of the interval to reproduce the 2nd data. Data D scattered over sectors of a disk are reproduced. Each sector has a 1st and a 2nd field. The 1st field stores signals not interleaved relative to signals of the 2nd field. A positional data of a leading sector is recorded in the 1st field. The leading sector is located in a 3rd field in which data D is recorded. The positional data is detected to reproduce the data D.
