Abstract:
1. A transmission method of performing transmission with use of parity packets, the transmission method comprising: a first error detection code insertion step of inserting at a certain layer, by a first error detection code insertion unit of a processor, error detection codes into information packets on a one-to-one basis to obtain first information packets, the certain layer being a layer at which signal processing is performed earlier than at a first layer; a parity packet generation step of generating at the certain layer, by a parity packet generation unit of the processor, parity packets by coding the information packets; a second error detection code insertion step of inserting at the certain layer, by a second error detection code insertion unit of the processor, error detection codes into the parity packets on a one-to-one basis to obtain first parity packets; a first layer coding step of coding at the first layer, by a first layer coding unit of the processor, the first information packets and the first parity packets to obtain second information packets and second parity packets, respectively, a transmission step of initially transmitting, by a transmission unit of the processor, the second information packets; and a parity packet transmission step of transmitting, by the transmission unit of the processor, the second parity packets to each of one or more receivers with reference to feedback information obtained from the receiver.
