Abstract
A decoding device that includes a decoding determination unit to determine a procedure of recovering and decoding missing packets in consideration of a packet missing pattern in data including a set of media packets and redundant packets generated by a two-dimensional XOR-based FEC encoding method. Further, a decoding unit executes the recovery of the missing packets according to the procedure determined by the decoding determination unit.
Claims20
An information processing device, comprising:
- circuitry configured to:
- calculate each of a number of rows and a number of columns with one missing packet of a plurality of media packets of data, wherein
- generation of the data is based on a two-dimensional XOR-based forward error correction (FEC) encoding process;
- compare the calculated number of rows with the calculated number of columns;
- determine a first recovery process of a plurality of recovery processes for the one missing packet;
- and
- execute the determined first recovery process in one of a row direction or a column direction based on the comparison.
A method, comprising:
- calculating each of a number of rows and a number of columns with one missing packet of a plurality of media packets of data, wherein
- generation of the data is based on a two-dimensional XOR-based forward error correction (FEC) encoding process;
- comparing the calculated number of rows with the calculated number of columns;
- determining a first recovery process of a plurality of recovery processes for the one missing packet;
- and
- executing the determined first recovery process in one of a row direction or a column direction based on the comparison.
A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a processor, cause the processor to execute operations, the operations comprising:
- calculating each of a number of rows and a number of columns with one missing packet of a plurality of media packets of data, wherein
- generation of the data is based on a two-dimensional XOR-based forward error correction (FEC) encoding process;
- comparing the calculated number of rows with the calculated number of columns;
- determining a first recovery process of a plurality of recovery processes for the one missing packet;
- and
- executing the determined first recovery process in one of a row direction or a column direction based on the comparison.
