Patent ID: 10165282

Abstract:
An image decoding method includes: receiving information on a set of reference pictures for configuring a set of reference pictures of a current picture, wherein the information on the set of reference pictures includes MSB that may calculate the MSB of POC of a long-term reference picture relative to the current picture, and flag information that represents whether there is MSB; and eliciting the set of reference pictures by using received MSB when the flag information is 1, and performing marking on the reference picture, wherein the flag information may be 1 when a temporal sub-layer identifier is 0, and there is at least one POC value for which a remainder obtained by dividing by a maximum value MaxPicOrderCntLsb is the same as LSB of the POC of the long-term reference picture, in a set of POCs of a previous picture including POC values related to the previous picture.
