Abstract
Video coding methods and apparatuses are provided. A set of two or more pictures is coded. The set includes at least a first picture coded with a first spatial resolution, and a second picture coded with a second spatial resolution different from the first spatial resolution. The set of two or more pictures is stored in a decoded picture buffer based on corresponding spatial resolutions. The set of two or more pictures stored in the decoded picture buffer is used as a set of reference pictures for coding one or more successive pictures subsequent to the set of two or more pictures. The set of two or more pictures is incorporated into a reference picture list that contains pictures with at least two different spatial resolutions.
