<p>A plurality of communication devices constitute a network. It is possible to reduce the time required for transmitting program data to all the communication devices and reduce the retransmission time of the program data. A unique frame processing unit (12) successively receives a program data frame containing program data divided into a plurality of parts, stores the received program data in a reception frame storage area (14a), and successively transfers the program data frame to a downstream communication device.</p> |
