Abstract: A method of efficient information coding is provided. The method may code a bin string for signaling prefix part of a binarized absolute value of a first vector component of a block vector difference (BVD) or a motion vector difference (MVD). The method may code a bin string for signaling a prefix part of a binarized absolute value of a second vector component of the BVD or the MVD. The method may also code a bin string for signaling a suffix part of a binarized absolute value and a sign of the first vector component. The method may further code a bin string for signaling a suffix part of a binarized absolute value and a sign of the second vector component.

Abstract: A method of SAO (sample-adaptive offset) processing is disclosed, where EO classification is based on a composite EO type group. The composite EO type group comprises at least one first EO type from a first EO type group and at least one second EO type from a second EO type group. The first EO type group determines the EO classification based on the current reconstructed pixel and two neighboring reconstructed pixels, and the second EO type group determines the EO classification based on weighted outputs of the current reconstructed pixel and a number of neighboring reconstructed pixels. A method of inter-layer SAO processing is also disclosed. An inter-layer reference picture for an enhancement layer is generated from the BL reconstructed picture and the inter-layer SAO information is determined, where at least a portion of the inter-layer SAO information is predicted or re-used from the BL SAO information.
