METHOD AND APPARATUS FOR IMAGE ENCODING/DECODING

摘要

Disclosed are a method and an apparatus for encoding/decoding an image, which support a plurality of layers. The method of decoding an image includes the steps of: interpreting layer dependence on a current layer in a VPS(Video Parameter Set) extension; interpreting the layer dependence on the current slice in a slice by determining whether the layer dependence is not used for the current slice or a new layer dependence in a range of the interpreted layer dependence in the VPS extension is used; and constituting a reference picture list about the current layer based on at least one of the layer dependence interpreted in the VPS and the slice.
