发明名称 Data sending/receiving system and method for a defect-free data transmission
摘要 In a data sending/receiving system (1), an information providing apparatus (2) including a content data storage unit (21) to store content data, a streaming data generator (22) to generate streaming transmission data from content data, a streaming interface (23), a download file generator (24) to generate a download file of content data and a download interface (25) for the download file, is connected to a data receiving terminal (3) including a storage control circuit (39) to control storage of content data into a content data recording unit (41), a packet information recording unit (40) to record data packet ID information and a packet resend requesting circuit (38) to request for resending a missing packet, via a network (4). Series of content data are sent by a connectionless-mode transmission whereas a missing packet is resent by a connection-mode transmission. Defect-free data can be transmitted with the real-time signal transmission being assured even when data is received, for recording, via a low-reliability network. <IMAGE>
