Abstract:
A communication system, comprising:a transmission device including: first reception means for receiving a transmission signal of a first data amount unit of a first format having first header information including a first error correction signal and first user information, said transmission signal being transmitted by a first transmission path, transmission signal generation means for generating a transmission signal of a second data amount unit of a second format by adding a second error correction signal to the transmission signal of the second data amount unit including at least one of second header information and second user information, wherein information obtained by removing the first error correction signal from the first header information of the transmission signal of the first format received by the first reception means is used as the second header information and the first user information is used as the second user information, and wherein redundant first header information is omitted from the second header information based on a payload count representing a repetition count, and transmission means for transmitting the transmission signal of the second format to a second transmission path; and a reception device including second reception means for receiving the transmission signal of the second format transmitted by the second transmission path, error correction means for performing error correction for the transmission signal of the second data amount unit on the basis of the second error correction signal included in the transmission signal of the second format received by the second reception means, error correction signal generation means for generating a third error correction signal serving as an error correction signal for the second header information corrected by the error correcting means, and transmission signal generation means for generating the transmission signal of the first format from header information including the third error correction signal and the second user information.
