Recording medium having data structure for managing recording and reproduction of multiple path data recorded thereon and recording and reproducing methods and apparatus
First Claim
1. An apparatus for reproducing video data having multiple reproduction paths from a recording medium, comprising:
- a controller configured to;
receive a request of a path change,determine an entry point based on an entry point fine table and the entry point coarse table in an entry point map,determine whether or not the path change is permitted by path information in the entry point map,determine a position where the path change is performed by identifying the path information in the entry point map, andcontrol the path change from a current path to the request path among the multiple reproduction paths based on the determined position if the path change is permitted,wherein the position is associated with the entry point in the video data, and the path information indicates whether or not the path change is permitted and indicates the position where the path change is performed if the path change is permitted.

Abstract
A method and apparatus for reproducing video data are discussed. According an embodiment, the apparatus includes a controller configured to receive a request of a path change, the controller configured to control the path change from a current path to the request path among the multiple reproduction paths by identifying path information in an entry point map, the path information associated with an entry point in the video data, and the entry point map having an entry point fine table including fine information of at least one entry point and an entry point coarse table including coarse information of the at least one entry point, the fine information and coarse information identifying a presentation time and an address for the at least one entry point.

-
a controller configured to; receive a request of a path change, determine an entry point based on an entry point fine table and the entry point coarse table in an entry point map, determine whether or not the path change is permitted by path information in the entry point map, determine a position where the path change is performed by identifying the path information in the entry point map, and control the path change from a current path to the request path among the multiple reproduction paths based on the determined position if the path change is permitted, wherein the position is associated with the entry point in the video data, and the path information indicates whether or not the path change is permitted and indicates the position where the path change is performed if the path change is permitted. - View Dependent Claims (2, 3, 4)

5. An apparatus for reproducing video data having multiple reproduction paths from a recording medium, comprising:
-
a controller configured to; receive a request of a path change from a current path to a request path among the multiple reproduction paths, determine an entry point based on an entry point fine table and the entry point coarse table in an entry point map, determine whether or not the path change is permitted based on the entry point map, and determine a position where the path change is performed based on the entry point map, and to control the path change based on the determination, wherein the position is associated with the entry point in the video data, the entry point map maps a presentation time and an address for one or more entry points, and the entry point map includes path information indicating whether or not the path change is permitted and indicating the position where the path change is performed if the path change is permitted. - View Dependent Claims (6, 7, 8, 9, 10)

11. A method for reproducing video data having multiple reproduction paths from a recording medium, comprising:
-
receiving a request of a path change from a current path to a request path among the multiple reproduction paths; determining an entry point based on an entry point fine table and the entry point coarse table in an entry point map; determining whether or not the path change is permitted based on the entry point map; determining a position where the path change is performed based on the entry point map, the position being associated with the entry point in the video data, the entry point map mapping a presentation time and an address for one or more entry points, the entry point map including path information indicating whether or not the path change is permitted and indicating the position where the path change is performed if the path change is permitted; and controlling the path change based on the determination. - View Dependent Claims (12, 13, 14)
