摘要： An encoding apparatus encodes image data using a picture order count (POC) that indicates a display order of a picture. The encoding apparatus includes a remainder calculating unit that calculates a remainder by dividing an absolute frame number counted from an instantaneous decoding refresh (IDR) picture by a divisor which is a number of reference frames in one POC cycle, and a remainder code converting unit that coverts the remainder calculated by the remainder calculating unit into a code. A decoding apparatus decodes image data using the POC. The decoding apparatus includes a remainder extracting unit that, when random access decoding is performed, extracts a remainder by decoding a remainder code added to a picture at a random decoding start position, and an initializing unit that initializes an input value of a decoding process for the POC, by using the remainder extracted by the remainder extracting unit.
摘要翻译：编码装置使用指示图像的显示顺序的图像顺序计数（POC）对图像数据进行编码。编码装置包括余数计算单元，该余数计算单元通过将从瞬时解码刷新（IDR）图像计数的绝对帧数除以一个POC周期中的参考帧的数目的除数和余数代码转换单元来计算余数，将由余数计算单元计算出的剩余量覆盖为代码。解码装置使用POC解码图像数据。解码装置包括：余数提取单元，当执行随机存取解码时，通过对在随机解码开始位置添加到图像的余数码进行解码来提取余数;以及初始化单元，用于初始化解码处理的输入值，通过使用由剩余提取单元提取的余数来生成POC。
