Abstract: 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.

Abstract: A method and apparatus for coding video data in a scalable or three-dimensional video coding system are disclosed. In one embodiment, context for the input data associated with an inter-layer or inter-view coding syntax element of a current block in an enhancement-layer (EL) or a dependent view is formed or the input data is parsed to identify the context based on information associated with one or more neighboring blocks, information associated with the current block, or both. In another embodiment, encoding or decoding is applied to the input data associated with the current block in the EL using inter-layer texture prediction based on the BL block in the BL, wherein a flag indicating whether there is any transform coefficient coded for the current block is signaled.
