Abstract
An encoding method and apparatus in a data communication system are provided. The method includes inputting a source block including a plurality of source payloads, converting the source block to an information block including a plurality of information payloads according to an Information Block Generation (IBG) mode selected from a plurality of IBG modes, transmitting a delivery block generated by adding a parity block generated by encoding the information block according to a selected encoding scheme to the source block to a receiver, and transmitting information indicating the selected IBG mode to the receiver.
Claims24
An encoding method in a data communication system, the method comprising:
- identifying a source block including a plurality of source payloads;
- generating a symbol block including a plurality of symbol payloads from the source block according to a generation mode from among a plurality of generation modes;
- encoding the symbol block according to an encoding scheme to make at least one packet;
- transmitting the at least one packet to a receiver;
- and
- transmitting, to the receiver, a signaling message including an information field indicating the generation mode,
- wherein each of the plurality of generation modes indicates how the symbol block is configured by using the plurality of source payloads included in the source block, and
- wherein, in at least one of the plurality of generation modes, the source block is split into a plurality of sub-blocks each including at least one of the plurality of source payloads, at least a portion of a sub-block is included in a symbol payload, and a source payload is placed into at least one symbol payload of the symbol block.
