Abstract: A recording apparatus for recording compressed video data has compressed video data generator for generating a compressed video data having a plurality of intra frames each of which has no cross-reference to any other frames, and bidirectional interpolated frames and predictive frames each of which has cross-reference to other frame. In the first cycle operation, address detector detects addresses of the intra frames and stores the detected addresses in a memory. A scan information generator generates, with reference to the stored addresses in the memory, scan information for an independent frame including one or two addresses of advanced intra frames and one or two addresses of previous intra frames. The scan information is inserted to each frame and then recorded on a disk. During the reproduce of the disk, the scan information is detected to have a quick access to the intra frame located near by.

Abstract: A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.
