 streaming, the downloaded content to the at least one target terminal via an Internet connection inside or outside a home network in the home network system, in response to the command; 
 analyzing the reserved word from the at least one target terminal and generating a search word for searching a content source; 
 receiving information on a content corresponding to the search word from the content source, generating the reservation list including the content information, and transmitting the reservation list to the at least one target terminal; 
 downloading a corresponding specific content from the content source in response to the command from the at least one target terminal; 
 performing control so that in response to a recording cancelling request, the recording cancelling requested content streamed from the content source stops being recorded; and 
 streaming the corresponding specific content downloaded from the content source to the terminal in response to a corresponding specific content transmitting request. 
 
     
     
       2. The method of  claim 1 , wherein the reserved word further includes at least one of a keyword, an inquiry, and schedule information. 
     
     
       3. The method of  claim 2 , wherein the content information includes at least one of image size information of the content, a title of the content, information on time when the content is aired, and image quality information. 
     
     
       4. The method of  claim 2 , wherein downloading the content included in the content information from the content source comprises:
 when recording cancellation is selected on a specific content among the at least one content included in the content information, stopping recording the specific content streamed from the content source in response to a recording cancelling request from the terminal, wherein stopping is performed by the digital media server. 
 
     
     
       5. The method of  claim 4 , wherein downloading the content included in the content information from the content source further comprises:
 deleting the recording cancelling requested content from the reservation list and updating the reservation list. 
 
     
     
       6. The method of  claim 2 , wherein downloading the content included in the content information from the content source comprises:
 when recording is selected on a specific content among the at least one content included in the content information, downloading the specific content from the content source in response to a content recording request from the terminal and initiating recording of the specific content. 
 
     
     
       7. The method of  claim 2 , wherein downloading the content and streaming the content further comprises:
 when playing is selected on a specific content among the at least one content included in the content information, downloading the specific content from the content source in response to a specific content transmitting request from the terminal and streaming the specific content to the terminal. 
 
     
     
       8. The method of  claim 1 , wherein streaming the downloaded content to the at least one target terminal from the digital media server includes:
 streaming the downloaded content to plural target terminals included in same reserved word in a multicast manner. 
 
     
     
       9. A digital media server used for a home network system, the digital media server comprising:
 a content processor configured to:
 receive a pre-registered reserved word including a first information related to at least one content to be reserved and a second information for at least one target terminal in the home network to reserve the at least one content from a terminal, 
 search the at least one content corresponding to the first information of the reserved word, 
 generate a reservation list for the at least one target terminal including content information on the searched content, the at least one target terminal corresponding to the content information in the reservation list, 
 transmit the reservation list to the at least one target terminal, 
 receive a command related to reserving the at least one content from at least one of the at least one target terminal, respectively, 
 download the content from a content source in response to the command, and 
 stream the downloaded content to the at least one target terminal via an Internet connection inside or outside a home network in the home network system, in response to the command; and 
 
 a reserved word analyzer configured to analyze the reserved word from the at least one target terminal and to generate a search word for searching the content source, 
 wherein the content processor includes:
 a content information generating unit configured to receive information on a content corresponding to the search word from the content source, to generate the reservation list including the content information, and to transmit the reservation list to the at least one target terminal, 
 a content downloading unit configured to download a corresponding specific content from the content source in response to the command from the at least one target terminal, 
 a content streaming control unit configured to perform control so that in response to a recording cancelling request, the recording cancelling requested content streamed from the content source stops being recorded, and 
 a content streaming unit configured to stream the corresponding specific content downloaded from the content source to the terminal in response to a corresponding specific content transmitting request. 
 
 
     
     
       10. The digital media server of  claim 9 , further comprising a content storage configured to store the reservation list. 
     
     
       11. The digital media server of  claim 9 , wherein the content information generating unit is configured to delete the recording cancelling requested content from the reservation list and to update the reservation list. 
     
     
       12. The digital media server of  claim 9 , wherein the reserved word includes at least one of a keyword, an inquiry, schedule information, and
