摘要:
A video decoder is configured to receive a bitstream including a first coded picture having a first resolution and a second coded picture having a second resolution, wherein the first coded picture is an intra-coded picture, parameters defining a cropping window. The decoder decodes the first coded picture and stores the first picture as a reference picture, determines a scaling factor from at least one parameter in the bitstream defining the first cropping window, determines a predictor for the second picture from the reference picture and the scaling factor, decodes the second coded picture using the predictor, and outputs for display the first picture as cropped in accordance with the parameters defining the cropping window.
