Abstract (en)

[origin: WO2021057629A1] The present disclosure relates to a method and apparatus for determining filtering related parameters for deblocking filtering on a sub-block edge between a first and a second sub-block of a coding unit that, even in the case of motion vector refinement, do not require refined motion information.
