Abstract
A data transmitting device connected to a prescribed network includes a coding device for receiving plural kinds of coded data, and coupling these coded data in first data units to generate a first coded stream. A divider divides the first coded stream into second data units of a prescribed data size to generate divided pack data corresponding to divided packs as the second units. A packet generating device adds header information to respective divided pack data to generate packet data corresponding to packets as data transmission units; and a transmitter outputs the respective packet data toward the network as a second coded stream which has a data structure different from that of the first coded stream.
