Hybrid retransmission method based on semantic coding

The invention discloses a hybrid retransmission method based on semantic coding. The method comprises the following steps: a main semantic codec and a plurality of incremental redundant semantic codec are trained for content to be transmitted; for a first type hybrid retransmission method, only one main semantic codec is used for replacing an original information source channel for coding and decoding, a sending end performs semantic coding and CRC check coding on an information source and sends the information source, a receiving end performs decoding and CRC check, and if errors exist, code words are discarded, and the sending end is notified to retransmit the same code words; for a second type hybrid retransmission method, the receiving end does not discard error code words after finding errors, the sending end is notified to continue to use an incremental redundancy semantic encoder to encode an information source and send the information source, and the receiving end combines all the received code words every time, uses the corresponding incremental redundancy semantic decoder to complete decoding and carries out CRC check.
