TRANSMISSION METHOD USING PARITY PACKETS, TRANSMITTER AND REPEATER

摘要

A packet error rate in a receiver needs to be effectively reduced.;Solution to Problem: A transmitter 11 inserts error detection codes into information packets on one-to-one basis, at a certain layer at which signal processing is performed earlier than at a physical layer, to obtain first information packets. The transmitter 11 codes the first information packets at the physical layer to obtain second information packets, and transmits the second information packets. At the certain layer, the transmitter 11 generates parity packets by coding the information packets and inserts the error detection codes into the parity packets on one-to-one basis to obtain first parity packets. The transmitter codes the first parity packets at the physical layer to obtain second parity packets. The transmitter 11 transmits the second parity packets in accordance with a transmission request from each of one or more receivers.

1. A transmission method executed by a transmitting apparatus to transmit a content to a plurality of terminals, wherein
the content has transmission count information indicating a number of times the content is to be transmitted by the transmitting apparatus, the transmission method comprising: a first transmission step of generating and transmitting a first transmission signal which transfers at least a first portion of a plurality of data packets configured by a plurality of content packets, storing data of the content therein, and by a plurality of parity packets, generated from the content packets, and a second transmission step of, when the transmission count information of the content indicates a plurality of times, generating a second transmission signal including at least a second portion of the plurality of data packets, and transmitting the second transmission signal during a period which differs from a period during which the first transmission signal is transmitted.
