FIELD: video encoding and decoding.
SUBSTANCE: inventions group relates to video encoding and decoding technologies, and more specifically, to signaling information related to reference image resampling and adaptive resolution change. A method for decoding an encoded video bitstream using at least one processor is proposed. The method includes the step of obtaining an encoded image from an encoded video bitstream. Next, the encoded image is decoded to form a decoded image. The first flag is obtained indicating whether resampling of the reference image is allowed. Next, a second flag is obtained indicating whether the reference pictures have a constant reference picture size. A third flag is obtained indicating whether the output images have a constant output image size specified in the encoded video bitstream.
EFFECT: improving the efficiency of encoding/decoding the video bitstream.
