Abstract: A video encoding method is provided. The method includes obtaining a list of reference pictures stored in a buffer, the reference pictures including pictures having different spatial resolutions.

The method further includes signaling, in a picture parameter set, syntax information indicative of a picture width and a picture height for each reference picture. The current picture is encoded with a spatial resolution determined based on the reference picture, wherein a ratio between the spatial resolution of the current picture and the spatial resolution of the reference picture is used for encoding.
