Abstract
A moving image coding apparatus which has coders (17, 18, 19) for dividing an input moving image signal into a plurality of frames, dividing each of the frames into one or more image areas, compressing and coding the image areas, and outputting an area image code string, a system multiplexer (20) for separating frame header information indicating the coding mode, etc., of the frame frame from the frame frame and adding the frame header information to one or more coded area image code strings, and a sender (25) for collecting one or more area image code strings to which the frame header information is added, adding packet header information, putting into a packet, and sending the packet.
