Apparatus and method for providing additional information using extension subtitles file
First Claim
1. An apparatus for providing additional information using an extensible caption file, the apparatus comprising:
- a data input unit to receive a multimedia file, a caption data file and an additional information data file as separate files;
an inverse multiplexing unit to separate video and audio data from the multimedia data file;
an XML parser to parse the caption data file and the additional information data file;
video and audio data processing units to decode the video and audio data input from the inverse multiplexing unit, and convert the decoded video and audio data into processed video and audio information;
a caption processing unit to process the caption data file parsed and input by the XML parser to generate processed caption information;
an additional information data processing unit to process the additional information data file parsed and input by the XML parser, and to generate user interface information based on the processed additional information data file; and
a data output unit to display the processed video, audio, caption and user interface information,wherein the user interface information is located in a layer upper than layers in which the caption and the video are located when the user interface information is displayed, andwherein the user interface information comprises a non-text type object.
