Method and apparatus for providing streaming data encoding

摘要

A method for encoding streaming data according to one embodiment of the present invention comprises: a step of dividing a forward error correction (FEC) source block into one or more FEC sub-blocks; a first encoding step of FEC encoding said one or more FEC sub-blocks; a second encoding step of encoding said FEC source block; and a step of generating third encoded data including first encoded data encoded in the first encoding step and second encoded data encoded in the second encoding step. According to one embodiment of the present invention, a streaming service is provided to multiple users in various environments or in a communication environment that varies according to movement or changes in a communication state. Further, a plurality of pieces of parity information is transmitted to provide a streaming service which is capable of high reliability data recovery.

1. A streaming data encoding method comprising:
dividing a forward error correction (FEC) source block into at least one FEC sub-block; performing first FEC encoding on the at least one FEC sub-block; performing second FEC encoding on the FEC source block; and generating a third encoding data including a first encoding data as a result of the first FEC encoding and a second encoding data as a result of the second FEC encoding, wherein the first encoding data includes an encoded FEC sub-block and a first parity payload of the encoded FEC sub-block, and the second encoding data includes a second parity payload of an encoded FEC source block.
