Provided are a method for managing a reference picture list, and an apparatus using same. An image decoding method comprises the steps of decoding one picture of second-highest temporal layer pictures in a hierarchical picture configuration; and decoding top temporal layer pictures which precede and follow the second-highest temporal layer pictures with respect to a picture order count (POC) in a POC sequence, respectively. Therefore, available reference pictures remain in a decoded picture buffer (DPB), thereby improving image-encoding efficiency.
