1. A method for decoding a coding unit, comprising:
determining that a coding unit spans over at least a first virtual pipeline decoding unit and a second virtual pipeline decoding unit without completely covering the first virtual pipeline decoding unit and the second virtual pipeline decoding unit;
in response to the determining, obtaining a coding mode for the coding unit in a sub-set of a set of coding modes larger than the sub-set, wherein the sub-set comprises at least one coding mode without dependency, wherein the coding mode without dependency is a coding mode involving at least one processing tool giving identical results whether the processing tool is applied to an entire coding unit or independently to each sub-block of the entire coding unit; and
decoding, based on the obtained coding mode, a coding unit sub-block falling entirely within the first virtual pipeline decoding unit independently of a coding sub-block falling entirely within the second virtual pipeline decoding unit.
