Method for generating a playlist and the system for the same
The present invention discloses a method for generating a playlist, which comprises: retrieving data of every video file stored in storing means; generating a video timeline based on the data, wherein the video timeline represents the video files arranged in order; setting at least one pair of beginning and end tags on the video timeline; creating a playlist by collecting all tags in that order; and storing the playlist in the storing means. With the present invention, users could edit a play sequence of a whole digital video disc in DVD-VR format by generating a playlist in a pretty easy and convenient way.
