Abstract:
1. An encoding apparatus that encodes image data using a picture order count (POC) that indicates a display order of a picture, the encoding apparatus comprising: 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; a remainder code converting unit that coverts the remainder calculated by the remainder calculating unit into a code a SEI generating unit that generates recovery point supplemental enhancement information (SEI) that is information related to a random start time; an adding unit that adds the remainder converted into the code by the remainder code converting unit to the recovery point SEI generated by the SEI generating unit; and a transmitting unit that transmits the recovery point SEI to which the remainder converted into the code by the remainder code converting unit is added, to a decoding apparatus.
