Abstract: A file transmission system and a file management method thereof that is capable, when files are transmitted between devices, of allowing the user to determine whether to download a file having a delete history, among those files, so that an undesired file is not transmitted. The file transmission system includes a host device to provide content files, a user device connected to the host device, the user device receiving the content files provided from the host device, and a controller to search for a delete history of a file to be transmitted from the host device to the user device and determine whether to transmit the file to be transmitted, if the file to be transmitted has the delete history. Therefore, it is possible to efficiently manage files having delete histories.

Abstract: The present invention relates to a method of processing a data structure for real-time image processing of huge-sized data, where the data structure of an original image comprising a plurality of pixels is processed, the method comprising the steps of: rearranging the plurality of pixels according to an index indicating the location of each pixel and determining the data containing the rearranged pixels as a region having a resolution lower than that of the original image; and recursively performing a transforming process of rearranging a part or all of the data containing the rearranged pixels in the aforementioned rearranging method and determining the rearranged data as a region having a resolution lower than that of the previous region, until a predetermined resolution is obtained.
