Abstract
Embodiments of the present invention relate to an apparatus. The apparatus includes a supplementary decoder and a memory. The supplementary decoder is configured to decode supplementary data. The supplementary data is associated at least one of audio data and video data. The memory is coupled to a supplemental video decoder. The memory is configured to record the start position of the decoded supplementary data. In embodiments, the apparatus includes a user input. The user input is configured to cause the apparatus to replay at least one of audio data and video data with the supplementary data starting from the start position of the decoded supplementary data stored in the memory.
Claims14
A method for reproducing sub-picture data in an optical disc device comprising:
- displaying sub-picture units on a screen;
- storing, on the optical disc device, a recording start position of each of the sub-picture units at a point in time when the sub-picture unit is displayed on the screen;
- receiving a predetermined user key input while displaying the sub-picture unit on the screen;
- searching for the recording start position of a sub-picture unit corresponding to search information generated in accordance with the received predetermined user key input, wherein the searched recording start position corresponds to a recording start position of the sub-picture unit being currently displayed when the user key input is received;
- and
- reproducing sub-picture data starting from the searched recording start position, wherein the storing comprises:
- storing a recording size of each of the sub-picture units displayed on the screen,
- storing search information associated with the each of the sub-picture units,
- comparing a recording size of successively inputted sub-picture units with the stored recording size of the sub-picture units,
- determining that successively inputted sub-picture units are new sub-picture units having new data when the comparing determines that the recording size of one of the successively inputted sub-picture units is different than the stored recording size of the sub-picture units, and
- storing the recording size of the successively inputted sub-picture units along with search information associated with the successively inputted sub-picture units when the successively inputted sub-picture units are determined to be new sub-picture units having new data, wherein the storing the recording size of the successively inputted sub-picture units is carried out to determine that new sub-picture data is displayed when the recording size of a current sub-picture unit does not correspond to the recording size of a sub-picture unit immediately preceding the current sub-picture unit.
