Abstract: Disclosed are methods for coding and decoding a multilayer video. The method for decoding a multilayer comprise: decoding a first layer picture and saving same to a decoded picture buffer (DPB); marking the first layer picture as a short-term reference picture; obtaining interlayer RPS information of a second layer picture which has a first POC identical to that of the first layer picture and which is interlayer-predicted by referencing the first layer picture; marking the first layer picture which has been marked as the short-term reference picture as a long-term reference picture, based on the interlayer RPS information; and performing interlayer prediction with respect to the second layer picture by referencing the first layer picture which has been marked as the long-term reference picture.
