Abstract
A coding method conversion apparatus converts the first coded data coded by the first coding method into the second coded data. The coding method conversion apparatus includes: an H.264 decoder which decodes the first coded data; a deblocking filter strength calculation unit which calculates a filter strength of deblocking filtering of a second coding method, using at least one piece of decoding information except a coding type of the first coded data, the decoding information being obtained by decoding the first coded data; and a deblocking filter which performs the deblocking filtering to reduce noise in a boundary of blocks according to the filter strength calculated by the deblocking filter strength calculation unit.
