摘要: A method for transform processing in video coding is disclosed. Embodiments according to the present invention reduce computational complexity of determining size a block corresponding prediction or block. The determination based on encoder information external without comparing costs associated with different sizes. can be information. may correspond system bandwidth, network power, remaining energy battery mobile device, timing budget related performing given size. In another embodiment, each performed only during cost evaluation data reconstruction.
