System and method for data transmission in dlna network environment

Abstract

A system and method for data transmission in a DLNA network environment are disclosed. The data transmission system includes a content creation unit creating at least one content, a content correlation check unit checking a created content to classify the created content by category and a conversion content creation unit extracting header information and body information of the classified content and converting the extracted information into preset type information.

1 . A data transmission system in a Digital Living Network Alliance (DLNA) network environment, comprising:
 a content creation unit creating at least one content;   a content correlation check unit checking the at least one created content to classify the at least one created content by category; and   a conversion content creation unit extracting header information and body information of each of the at least one classified content and converting the extracted information into preset type information.   
   
   
       2 . The data transmission system of  claim 1 , wherein the content correlation check unit classifies a content into an audio content or image content. 
   
   
       3 . The data transmission system of  claim 2 , wherein the content correlation check unit further classifies the content classified as an audio content or image content by indexes. 
   
   
       4 . The data transmission system of  claim 2 , wherein the conversion content creation unit converts the audio content header information, extracted from the content, into MPEG-7 type metadata. 
   
   
       5 . The data transmission system of  claim 2 , wherein the conversion content creation unit converts the audio content body information, extracted from the content, into MPEG-4 or MAF type information. 
   
   
       6 . The data transmission system of  claim 2 , wherein the conversion content creation unit converts the image content header information, extracted from the content, into one of MPEG-7 MDS metadata and MPEG-7 visual metadata. 
   
   
       7 . The data transmission system of  claim 1 , wherein the conversion content creation unit:
 extracts supplementary information from the at least one created content; and   generates supplementary metadata based on of the extracted supplementary information.   
   
   
       8 . The data transmission system of  claim 1 , wherein the conversion content creation unit combines multiple related content into a unified file on the basis of the classification result. 
   
   
       9 . The data transmission system of  claim 8 , further comprising:
 a content directory service unit creating and providing a list of content, list of converted contents, and list of unified files;   a content storage unit storing at least one of contents, converted contents and unified files; and   a content transmission unit transmitting at least one of contents, converted contents and unified files.   
   
   
       10 . A method for data transmission in a Digital Living Network Alliance (DLNA) network environment, comprising:
 creating a content;   classifying the created content by checking the category of the content; and   extracting header information and body information of the content classified by category, and converting the extracted information into preset type information.   
   
   
       11 . The method of  claim 10 , wherein classifying a created content comprises:
 classifying the content into an audio content or an image content.   
   
   
       12 . The method of  claim 11 , wherein classifying a created content further comprises:
 classifying the content classified as an audio content or image content by indexes.   
   
   
       13 . The method of  claim 11 , wherein converting the extracted information comprises:
 converting an audio content header information, extracted from the content, into MPEG-7 type metadata.   
   
   
       14 . The method of  claim 11 , wherein converting the extracted information comprises:
 converting body information of the audio content extracted from the content into MPEG-4 or MAF type information.   
   
   
       15 . The method of  claim 11 , wherein converting the extracted information comprises:
 converting an image content header information extracted from the content into one of MPEG-7 MDS metadata and MPEG-7 visual metadata.   
   
   
       16 . The method of  claim 10 , wherein extracting header information and body information further comprises:
 extracting supplementary information from a created content; and   generating supplementary metadata based on of the extracted supplementary information.   
   
   
       17 . The method of  claim 10 , wherein extracting header information and body information comprises:
 combining multiple related contents into a unified file on the basis of the classification result.   
   
   
       18 . The method of  claim 17 , further comprising:
 storing the contents, converted contents and unified files;   creating and providing a list of content, list of converted content, and list of unified files; and   transmitting at least one of said contents, converted contents and unified files.
