A moving picture streaming file, method and system for a moving picture streaming service of a mobile communication terminal. The streaming file is generated by adding audio payload data to an MJPEG moving picture file, and adding payload headers for controlling streaming of each payload data. When the mobile communication terminal requests the streaming service, a server provides the previously-generated wireless moving picture streaming file to the terminal. The terminal then plays the payload data using payload header information of the streaming file, and controls transmission of the payload data including a plurality of segments using segment headers.
