Abstract (en)

[origin: WO2020188149A1] There are disclosed a method and an apparatus for video encoding. A method may include generating a bitstream of coded video sequence comprising pictures in a picture order; wherein the generating comprises 1) for a first picture of the video sequence, coding a region on a corner of the picture in intra mode to generate a refresh region; and 2) repeating the following for each subsequent picture of the video sequence in a picture order:coding a region corresponding to the refresh region of a previous picture in inter mode, and coding a region that is diagonally next to the region corresponding to the refresh region of the previous picture in intra mode to expand the refresh region, and indicating in a bitstream a use of a diagonal refresh and transmitting the coded bitstream to a decoder.
