A coding device (101) encodes image data with the coding self-contained within specific image data units, and supplies the encoded data stream to a packetizer (103) to generate packets from the encoded image data stream, and a packet header adding device (104) adds to each packet a packet header containing time information whereby the temporal position of the packet is determined. Thus, temporal information associated with data received after recovery of an error can be known immediately by the receiver even when an error occurs on the communications network over which a data stream containing image data, audio data, and other information is transmitted. <IMAGE> |
