Method and apparatus for encoding/playing multimedia contents
First Claim
1. A method of encoding multimedia contents, comprising:
- separating media data and metadata from multimedia contents;
creating metadata complying with a predetermined multimedia application format (MAF) by using the separated metadata; and
encoding the media data and the metadata complying with the standard format, and thus creating an MAF file including a header containing information indicating a location of the media data, the metadata and the media data.

Abstract
A method and an apparatus for encoding and playing multimedia contents are provided. The method includes: separating media data and metadata from the multimedia contents; creating multimedia application format (MAF) metadata by using the separated metadata, the format of the MAF metadata being predetermined; and encoding the media data and the MAF metadata to generate an MAF file including a header, the MAF metadata, and the media data, the header having information that provides a location of the media data. Accordingly, in a process of integrating digital photos and other multimedia content files into one file in the application file format MAF, visual feature information obtained from photo data and the contents of the photo images, and a variety of hint feature information for effective indexing of photos are included as metadata and content application method tools based on the metadata are included. As a result, even when the user does not have a specific application or a function for applying metadata, general-purpose multimedia content files can be effectively used by effectively browsing the multimedia content files.

38. A method of playing multimedia contents, comprising:
-
decoding an MAF file including a header and application data to extract media data, media metadata, and application data, the header having information that provides a location of media data, the application data providing media application method information having at least one single track with media data and media metadata; and
playing the multimedia contents using the extracted metadata and the application data. - View Dependent Claims (39)

40. An apparatus for encoding multimedia contents, comprising:
-
a pre-processing unit separating media data and metadata from multimedia contents;
a media metadata creation unit creating MAF metadata by using the separated metadata, the format of the MAF metadata being predetermined; and
an encoding unit encoding the media data and the MAF metadata to generate an MAF file including a header, the MAF metadata, and the media data, the header having information that provides a location of the media data. - View Dependent Claims (41, 42, 43, 44, 45, 49, 50, 51, 52, 53)

54. An apparatus for playing multimedia contents, comprising:
-
an MAF decoding unit decoding an MAF file including a header having information that provides a location of media data, at least one single track having media data and media metadata, and application data representing media application method information to extract the media data, media metadata, and the application data; and
an MAF playing unit playing the multimedia contents by using the extracted metadata and application data. - View Dependent Claims (55)
