Abstract
A method of signaling of coding modes including an IntraBC mode (Intra-block copy mode) to improve the coding efficiency is disclosed. The embodiment takes into consideration the facts that Inter prediction is more common in Inter slices than IntraBC prediction. In another embodiment, a binary sub-tree is disclosed that includes all the partition modes associated with IntraBC mode and the binary sub-tree consists of only said all members of the partition mode group.
