Patent ID: 8111976

Claim:
A method of reproducing a sub-picture in a reproducing apparatus for display thereof, comprising: decoding video data within a recording medium according to a play speed of a trick play mode of the reproducing apparatus via the reproducing apparatus and displaying the decoded video data; and selectively decoding at least one of a plurality of sub-picture data within the video data that is being decoded via the reproducing apparatus and displaying the decoded sub-picture data during a time displayed in a normal play mode, wherein a display-off time point of the decoded sub-picture data depends on a value found by adding a start time of a corresponding sub-picture display control sequence to a first PTS (presentation time stamp) of the video data that is being decoded, wherein, when next video data is displayed, sub-picture data within the next video data is skipped while the displayed sub-picture data is displayed, and a next sub-picture data to be decoded is selected based on the display-off time point and the play speed of the trick play mode, wherein the selected next sub-picture data is decoded and displayed based on the first PTS of video data that is being decoded after the display-off time point, when a STC (system time clock) is greater than a PTS of the decoded next sub-picture, and wherein the STC is not greater than the first PTS of video data that is being decoded after the display-off time point.
