According to an embodiment, a method includes a step of receiving an input video stream including one or more pictures having a first size from a single encoding engine and a step of generating a plurality of encoded streams by the single encoding engine; first encoded streams includes the pictures having the first size, second encoded streams includes pictures having a second size smaller than the first size, and the encoding of the second streams is based on video coding information sharing used for the encoding of the first encoded streams. [Reference numerals] (502) Receive an input video stream including one or more pictures of a first size from a single encoding engine; (504) Generate a plurality of streams having different picture sizes in parallel by the single encoding engine based on the input video stream; (506) Map macro blocks from a down-scaled picture of a stream with a block among streams having pictures of the first size; (508) Map motion vectors with down-scaled blocks; (510) Generate a plurality of encoded streams having different sizes in parallel by the single encoding engine based on sharing video coding information used for encoding a first encoded stream; (AA) START; (BB) END |
