INTER-LAYER TEXTURE CODING WITH ADAPTIVE TRANSFORM AND MULTIPLE INTER-LAYER MOTION CANDIDATES

摘要

Methods of adaptive transform type based on transform unit (TU) size for enhancement layer (EL) coding and multiple motion candidates for EL coding based on corresponding base layer (BL) video data are provided. One method selects a transform type from multiple allowable transform types based on the TU size and applies the selected transform type to the transform units of the inter-layer prediction processed data. Another method derives multiple motion candidates for the EL video data coded in Merge mode or Inter mode based on motion information associated with the corresponding BL video data.

1. A method of inter-layer prediction for scalable video coding, wherein video data is configured into a Base Layer (BL) and an Enhancement Layer (EL) and wherein EL video data has higher spatial resolution or better video quality than BL video data, the method comprising:
receiving input data associated with the EL video data, wherein the EL video data is partitioned into TUs (transform units) and each TU has a TU (transform unit) size; and applying a first type transform/inverse transform or a second type transform/inverse transform to the input data corresponding to a current TU of the EL video data depending on a current TU size.
