REMAINING BUFFER CAPACITY LIMIT PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a remaining buffer capacity limit processor which improves the degradation of picture quality after the limitation of remaining buffer capacity. SOLUTION: A remaining capacity limiting range detecting means 11 detects a remaining capacity limiting range as the range to limit remaining buffer capacity. A distribution ratio calculating means 12 calculates a distribution ratio so that the distribution ratio of bit amount to respective pictures in the remaining capacity limiting range can be equal with the ratio before the remaining capacity is limited. Based on the distribution ratio, a bit amount calculating means 13 calculates the amount of bits to be distributed to the pictures.
