MPV file creating method and apparatus, and storage medium therefor

Abstract

A method and apparatus are provided for creating a MultiPhotoVideo or MusicPhotoVideo (MPV) file that enables minimization of resources and/or storage capacity required to use the MPV file in a multimedia application environment, and a storage medium having recorded thereon a computer readable program for performing the method. The method includes: generating profilebag elements based on multimedia content; generating unique identification information of assets included in the multimedia content; generating a last uniform resource locator (LastURL) based on universal resource identifiers (URIs) of the assets included in the multimedia content; and creating an MPV file corresponding to the multimedia content using the profilebag elements, the unique identification information of the assets, and the LastURL. Accordingly, the MPV file, which is available to multimedia reproducing devices having limited resources and/or storage capacity, can be provided.

1 . A MultiPhotoVideo or MusicPhotoVideo (MPV) file creating method comprising: 
 generating profilebag elements based on multimedia content;    generating unique identification information of assets included in the multimedia content;    generating a last uniform resource locator (LastURL) based on universal resource identifiers (URIs) of the assets included in the multimedia content; and    creating an MPV file corresponding to the multimedia content based on the profilebag elements, the unique identification information of the assets, and the LastURL.    
   
   
       2 . The method of  claim 1 , wherein in the creating of the MPV file, one predetermined namespace is used for each prefix.  
   
   
       3 . The method of  claim 1 , wherein in the creating of the MPV file, metadata is generated on the basis of a metadata format defined in the MPV specification.  
   
   
       4 . The method of  claim 1 , wherein in the creating of the MPV file, the MPV file is created on the basis of an eXtensible Markup Language (XML) without XML entities.  
   
   
       5 . The method of  claim 1 , wherein the unique identification information of each asset is “mpv:id.” 
   
   
       6 . A MultiPhotoVideo or MusicPhotoVideo (MPV) file creating apparatus comprising: 
 a profilebag element generator which generates profilebag elements based on multimedia content which is input;    an identification information generator which generates unique identification information of assets included in the multimedia content;    a last uniform resource locator (URL) generator which generates a last URL (LastURL) based on universal resource identifiers (URIs) of the assets included in the multimedia content;    a namespace provider which provides one namespace for each prefix;    an MPV file formatter which controls an MPV file corresponding to the multimedia content on the basis of the profilebag elements generated by the profilebag element generator, the unique identification information generated by the identification information generator, the LastURL generated by the last URL generator, and the namespaces provided by the namespace provider, and generates metadata of the MPV file; and    a metadata generating controller which controls the MPV file formatter to generate metadata of an MPV file based on a metadata format defined by the MPV specification.    
   
   
       7 . A storage medium having recorded thereon a computer readable program for performing a MultiPhotoVideo or MusicPhotoVideo (MPV) file creating method in a multimedia application environment, the MPV file creating method comprising: 
 generating profilebag elements based on multimedia content;    generating unique identification information of assets included in the multimedia content;    generating a last uniform resource locator (URL) based on universal resource identifiers (URIs) of the assets included in the multimedia content; and    creating an MPV file corresponding to the multimedia content based on the profilebag elements, the unique identification information of the assets, and the LastURL.
