Claim:
1. A method for video decoding which supports multi-layer videos, the method comprising: analyzing a first layer dependency on a current layer based on a video parameter set (VPS) extension; analyzing a second layer dependency on a current slice in the current layer based on information encoded in a slice unit, wherein analyzing the second layer dependency on the current slice comprises determining, for the current slice, whether to use the first layer dependency of the VPS extension or the second layer dependency of the slice unit; and constructing a reference picture list for the current slice based on at least one of the first layer dependency on the current layer or the second layer dependency on the current slice, wherein the reference picture list includes a temporal reference picture belonging to a same layer as the current slice and an inter-layer reference picture belonging to a different layer from the current slice, and wherein the inter-layer reference picture has a same POC (picture order count) value as the current slice.
