Abstract  Abstract

A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units determines a multiplex code on the basis of respective information amounts derives a parity of the first determined multiplex code to form a second multiplex code adds a CRC to each of the multiplex codes to generate two headers H 1 and H 2 takes out information data of respective media according to the multiplex codes incorporates the information data into a packet together with the two headers H 1 and H 2 and outputs the packet. If error correction of H 1 is impossible on the receiving side error correction decoding is conducted by using the header H 2. If error correction of H 2 is also impossible error correction decoding is conducted collectively for H 1 and H 2.
