Abstract
A receiver includes a processor. The processor is configured to receive first data blocks and a first parity block from a transmitter. The first data blocks are obtained by dividing first transmission data at a predetermined size. The first parity block is generated on basis of the first data blocks. The processor is configured to restore a first missing block on basis of first received blocks and the first parity block. The first missing block is an unsuccessfully received block of the first data blocks. The first received blocks are successfully received blocks of the first data blocks. The first parity block is successfully received.
Claims17
A receiver, comprising:
- a processor configured to
- receive first data blocks and a first parity block from a transmitter, the first data blocks being obtained by dividing first transmission data at a predetermined size, the first parity block being generated on basis of the first data blocks, and
- restore a first missing block on basis of first received blocks and the first parity block, the first missing block being an unsuccessfully received block of the first data blocks, the first received blocks being successfully received blocks of the first data blocks, the first parity block being successfully received.
A transmitter, comprising:
- a buffer memory configured to
- temporarily store first transmission data to be transmitted to a receiver;
- and
- a processor configured to
- obtain first data blocks by dividing the first transmission data stored in the buffer memory at a predetermined size,
- generate a first parity block on basis of the first data blocks,
- add first information to each of the first data blocks and the first parity block, the first information indicating a first group corresponding to the first transmission data, and
- transmit the first data blocks and the first parity block together with the first information to the receiver.
A data transmission system, comprising:
- a transmitter including
- a first processor configured to
- obtain first data blocks by dividing first transmission data at a predetermined size,
- generate a first parity block on basis of the first data blocks, and
- transmit the first data blocks and the first parity block;
- and
- a receiver including
- a second processor configured to
- receive the first data blocks and the first parity block from the transmitter, and
- restore a first missing block on basis of first received blocks and the first parity block, the first missing block being an unsuccessfully received block of the first data blocks, the first received blocks being successfully received blocks of the first data blocks, the first parity block being successfully received.
