PURPOSE:To constitute the communication network tying a wide variety of stations, by performing transmission with the correction code block made for the arrangement through interleaving after the synchronizing signal and with the format of message of code block succeedingly. CONSTITUTION:The parity codes P1 to Pn correctable at the reception side are added to each character, arranged immediately before the original information I1 to In block, and only the added arrangement is interleft and rearranged. The synchronizing signal PN informs to the reception station for the start position of error correction in one message. The station b makes transmission with this system B, and when the station a of the system A without correction and the station c of conventional correction system C receive it, the both stations print the received message as it is and the reading is made by taking into account the ineffective print. Although the reception of the station a b and a c is enabled, but the reception of the station c a and c b is disabled due to difference of the message system for the code transmission. As shown in the solid and broken lines for the transmission and reception and only reception, the stations using the system B increase the number of mutual transmission line than the stations a and c in other systems. |
