Patent ID: 8244742

Claim:
A method for data communications based on a Digital Living Network Alliance (DLNA network), the method comprising: searching stored contents files by a digital media server (DMS) in response to a request; extracting a non-supported file which the DLNA network does not support from among the contents files; assigning a virtual file name to the extracted file not supported by the DLNA network; the virtual file name distinguishing the file as being a file not supported by the DLNA network from a file supported by the DLNA network; generating a contents list including the name of the virtual file and names of files that the DLNA network supports; providing the contents list to a Digital Media Controller (DMC); selecting one of the generated contents list, by the DMC; determining whether the selected contents file is a non-support file, by the DMS; generating, by the DMS, a conversion file by converting a file attribute when the selected file is a non-supported; and transmitting the conversion file to a digital media renderer (DMR) by the DMS.
