摘要：: A method of decoding multi-layer video includes decoding a first layer picture, storing the decoded first layer picture in a decoded picture buffer (DPB), and marking the first layer picture as a short-term reference picture; obtaining interlayer reference picture set (RPS) information regarding a second layer picture having a same first picture order count (POC) as the first layer picture; marking the first layer picture, which is marked as the short-term reference picture, as a long-term reference picture, based on the interlayer RPS information; performing interlayer prediction with respect to the second layer picture with reference to the first layer picture; decoding the second layer picture based on a result of performing the interlayer prediction; and, after the second layer picture is decoded, marking the first layer picture, which is marked as the long-term reference picture, as a short-term reference picture.
主权项：: 1. A method of decoding multi-layer video, the method comprising: decoding a picture of a first layer; storing the decoded picture of the first layer in a decoded picture buffer (DPB); marking the decoded picture of the first layer as a short-term reference picture; obtaining interlayer reference picture set (RPS) information regarding a picture of a second layer having a second picture order count (POC) that is the same as a first POC of the picture of the first layer; marking the picture of the first layer, which is marked as the short-term reference picture, as a long-term reference picture based on the interlayer RPS information; performing interlayer prediction with respect to the picture of the second layer with reference to the picture of the first layer; decoding the picture of the second layer based on a result of performing the interlayer prediction; and marking the picture of the first layer, which is marked as the long-term reference picture, as a short-term reference picture.
