VIDEO CODING DEVICE AND VIDEO CODING METHOD

摘要

A video coding device (100) has a buffer simulation section (103) which computes the occupancy amount of a virtual buffer to be used for controlling a code amount by using per-picture code lengths of a code being the halfway result of compression coding processing and a compressed code being the final result. That is, with respect to a picture before the finish of compression coding by an arithmetic coding section (102), the occupancy amount of the virtual buffer is computed by using the code length of a code outputted from a binarization section (101).
