    Abstract: A video encoding device includes: a first video encoding section 11 for encoding an input image to generate first coded data; a buffer 12 for storing the input image; a coded data transcoding/merging section 13 for transcoding and then merging the first coded data generated by the first video encoding section 11, to generate second coded data; and a second video encoding section 14 for estimating a syntax value for encoding the input image stored in the buffer 12 based on the second coded data supplied from the coded data transcoding/merging section 13, to generate a bitstream. The first video encoding section 11 has a function of handling a first encoding process included in a second encoding process handled by the second video encoding section 14. The coded data transcoding/merging section 13, in the case where a predetermined condition is met, merges frequency transform/quantization blocks in the second encoding process.

    Abstract: A video encoding device includes: first video encoding means for encoding an input image to generate first coded data; a buffer for storing the input image; coded data transcoding means for transcoding the first coded data generated by the first video encoding means, to generate second coded data; and second video encoding means for generating a prediction signal based on the second coded data supplied from the coded data transcoding means. The first video encoding means includes: dividing means for dividing the input image into a plurality of image areas; and at least one encoding means corresponding to the image areas each of which is made up of a plurality of blocks, and for performing encoding in units of blocks. The encoding means also encodes a block that is included in an image area adjacent with a dividing line in between and is located near the dividing line.
