A benefit of using the IBC mode is a referencing structure of the IBC mode where a two-dimensional (2D) spatial vector can be used as the representation of an addressing mechanism to reference samples. A benefit of an architecture of the IBC mode is that the integration of IBC requires relatively minor changes to the specification and can case the implementation burden if manufacturers have already implemented certain inter prediction technologies, such as the HEVC version 1).
