Abstract
The present disclosure provides an encoding and decoding device, as well as an encoding and decoding method. In particular, the present disclosure relates to method for decoding of a video bitstream implemented by a decoding device, wherein the video bitstream includes data representing a coded picture comprising tile columns, the decoding method comprising: obtaining a syntax element by parsing the video bitstream, wherein the syntax element is used to derive the width of the tile columns, wherein the width of the tile columns is uniform; predicting the picture according the width of the tile columns.
