Abstract: A method of video decoding is provided. In the method, a coded video bitstream including a current picture is received. Whether a current block included in the current picture is coded in an intra block copy (IBC) mode is determined. In response to determining that the current block is coded in the IBC mode, a maximum number of IBC predictor candidates associated with the current block is determined as equal to a value of max(M, MaxNumMergeCand). The MaxNumMergeCand is equal to a number of candidates in a merge mode list and the M is a predetermined integer. An IBC predictor candidate list is constructed based on the maximum number of IBC predictor candidates. A block vector associated with the current block is determined based on a block vector predictor included in the IBC predictor candidate list. The current block is reconstructed based on the block vector.

Abstract: A direct current (DC) electric motor assembly with a closed type overlap stator winding which is commutated with a timed commutating sequence that is capable of generating a stator rotating magnetic field. The coil overlap of the winding and a timed commutation sequence are such that the current in each slot of the stator is additive and when a previous magnetic pole collapses according to a commutation sequence; the energy released by that previous collapsing magnetic field is captured to strengthen the next magnetic field on the commutation sequence schedule. Electrical currents produced by the collapsing magnetic fields flow to low electric potential and add or subtract to the DC current provided by the commutator thus promoting formation of the next magnetic on commutation schedule. When used with a suitable commutator and rotor, the electric motor assembly provides a true brushless high torque speed controlled Real Direct Current (RDC) motor that operates with higher efficiency and higher power density.
