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

摘要： Methods for determining reference type of each image unit and adjusting the corresponding lambda table of the reference type are disclosed. Embodiments according to the invention are used to improve the quality of video compression or reduce the requirement of memory buffer, memory power or computation power. The reference type is determined based on the encoder system information or image unit information. The frame/slice type structure of a video sequence is adjusted according to the image unit information of encoded frames or together with input frames. By fine-tuning the mode decision process, the coding efficiency can be improved. The mode decision process is modified by adaptively adjusting the lambda table. The lambda table is adaptively determined according to the conventional image unit type (such as Intra coded, predicted or bi-directional predicted type) and the reference type determined.
