PURPOSE: A dual mosaic file architecture, and a streaming device and a method using the same are provided to carry out streaming using the dual mosaic file architecture in order to enable a user to download and correctly view a desired part. CONSTITUTION: A communicator(401) secures a communication port if a request is received from a client. A thread generator(402) generates a thread managing a streaming service and transmits the basic information. A block requestor(403) transmits the position information of a large and a small block image requested from the client. A database manager(404) transfers a query to a database, and transfers the handle of an image file to a block extractor(406). A block sequence rearranger(405) rearranges a transfer order of the small block as an order of a concentric circle, adds the position information of the changed small block to a front part of the small block information, and transfers it to the communicator. The block extractor transfers the image information, the outline image information, and the common image header information of the small block to the communication part, and transfers the small block information to the block sequence rearranger.
