Abstract:
A method and apparatus for video coding operates by receiving input data associated with a current block in a current picture, determining restricted prediction based on whether IntraBC prediction (Intra Block Copy prediction) is included in a plurality of candidate coding modes, wherein said determining the restricted prediction comprising disabling or disallowing selected prediction for one or more selected PU (prediction unit) sizes, PU prediction types or both, and applying video coding to the current block using the candidate coding modes including IntraBC prediction (Intra Block Copy prediction) in accordance with the restricted prediction.
