Device-adaptable contents generation device, contents Device-adaptable contents generation device, contents reproduction device, and method thereof

A device-adaptable contents reproduction device comprising:

• a contents analysis unit configured, based on both media information extracted from a file of content loaded from a contents generation device upon request and specification information of a terminal device, to determine a resolution suitable for reproduction of the loaded content;
• a media loading unit configured, based on the determined resolution,to load only basic level media contained in the loaded content or both the basic level media and at least one extended level media contained in the loaded content;
• a media combination unit configured to create a combined media by combining the basic level media and the at least one extended level media loaded from the media loading unit;
• and
• a media decoding unit configured to decode the basic level media or the combined media and to display the decoded media on a display unit.

A device-adaptable contents generation method comprising steps of:

• generating basic level media having a first resolution on the basis of rich media content;
• generating at least one extended level media having a higher resolution by stages than a first resolution of the basic level media;
• generating metadata for allowing selective access to the basic level media and the at least one extended media;
• generating feature information about the rich media content;
• and
• storing a file of the rich media content containing the feature information, the metadata, the basic level media and the at least one extended level media in a database.

A device-adaptable contents reproduction method comprising steps of:

• determining a resolution suitable for reproduction of content composed of multistage media;
• based on the determined resolution, generating a combined media by combining selectively the multistage media of the content;
• and
• decoding the combined media to reproduce the decoded media on a display unit.
