Abstract
A method and apparatus for recording additional data such as graphic and subtitle data to be overlaid on a main video on a high-density recording medium and for reproducing the recorded additional data is disclosed. The method and apparatus in accordance with the present invention receives video data and additional data including graphic data and/or subtitle data and records the additional data as a plurality of streams on the recording medium by dividing and organizing the additional data in such a way that the additional data is included in a plurality of regions that will be overlaid on a video image constructed from the video data.
Claims23
A method for recording graphic/subtitle data on a recording medium, comprising the steps of:
- receiving video data and additional data including graphic data and/or subtitle data;
- and
- recording the additional data on the recording medium by dividing and organizing the additional data in such a way that the additional data is included in a plurality of regions that will be overlaid on a video image constructed from the video data.
A method for recording graphic/subtitle data on a recording medium, comprising the steps of:
- receiving video data and additional data including graphic data and/or subtitle data;
- and
- recording the additional data as a plurality of individual streams on the recording medium.
A high-density recording medium having video data and additional data including graphic data and/or subtitle data, wherein the additional data is divided and organized in such a way that the additional data is included in a plurality of regions that will be overlaid on a video image constructed from the video data.
A high-density recording medium having video data and additional data including graphic data and/or subtitle data, wherein the additional data is recorded as a plurality of individual streams.
An apparatus for recording graphic/subtitle data on a recording medium, comprising:
- first means for receiving video data and additional data including graphic data and/or subtitle data;
- second means for dividing and organizing the additional data in such a way that the additional data is included in a plurality of regions that will be overlaid on a video image constructed from the video data;
- and
- third means for recording the additional data and the video data on the recording medium.
